Watch Out for these Air and Heating Scams

It’s not uncommon for reputable heating and air conditioning manufacturers to offer fall and winter deals on system replacements. In the southwest, it’s a way to give a small boost to a contractor’s slow season while also rewarding forward-thinking consumers who don’t want to contend with a mid-summer breakdown.

“This is the slow time of year for our trade and manufacturers know that; so they’ll offer better incentives,” said Josh Morehart, president of Morehart Heating & Air Conditioning, in Phoenix. “Sometimes, they might sell off some overstock, but they’re still brand-new systems with full warranties.”

Unfortunately, this is also the time of year where less-reputable contractors offer deals that are too good to be true. With some due diligence, Morehart says consumers can protect themselves from a bad situation.

Questionable warranties

At the heart of a sketchy deal you’ll often find an exuberant warranty claim. A reputable manufacturer carries a 10-year warranty. Longer ones may not be actual factory warranties, but contractor warranties, instead, explained Morehart.

“If that contractor goes out of business, you’ve paid for a service you’ll never receive. … You have to make sure it’s a manufacturer-backed warranty,” the HVAC pro emphasized.

Know about SEER ratings

The SEER (Seasonal Energy Efficiency Rating) rating of a system is one of today’s most critical talking points when buying a new heating and air conditioning system. The higher the SEER rating, the more efficient the system is – or the less energy it requires to do its job.

As of Jan. 1, 2015, a 14-SEER rating is the minimum for the southwest region (which includes Arizona), according to the U.S. Department of Energy. However, an 18-month sell-through period has been established where 13-SEER units can still be sold as long as the equipment was built prior to Jan. 1, 2015.

Unfortunately, some unscrupulous contractors will purchase 13-SEER units from a northern region vendor. These systems may not be compliant with local standards. “It’s a big no-no, but it’s happening,” Morehart added.

Unknown brands

At the heart of a bad deal masked by an incredible price is a brand you haven’t heard of. Unfortunately, there are some lesser-heard names that may not even offer warranty service in the U.S.

“There are brands that used to sell in the U.S. but they’ve pulled out of the country and don’t have support here,” Morehart said. “You may be in a situation where they’ll honor a warranty, but you have to pull the part out and ship it to China. It could take two to four months to get it back.”

Used versus new

Some scams will try to pass off used equipment as new. Buying used equipment is not uncommon for those who own rental properties. At times, Morehart’s team even has refurbished units on hand, but it must be made clear to the buyer that the unit is used.

“There are some who will try to sell it as a new unit,” he added. “If the price is far lower than expected, you need to make sure you’re not getting scratch and dent equipment or equipment that can’t be registered. … We’ve even seen situations where the equipment was stolen.”

Questions to ask

Morehart suggests taking the following due diligence steps:

Make sure the contractor is an actual manufacturer’s distributor. You can visit the manufacturer’s website or call them directly.
Check the state’s Registrar of Contractors (ROC) to see if there has been any disciplinary action filed against the seller.
Ask for testimonials and check the Better Business Bureau (BBB) website for complaints.
Ask the contractor if the unit is SEER compliant and don’t be afraid to follow up with the manufacturer with serial number in hand if you suspect the unit is either used or does not meet regional standards.

Clean Your A/C Condenser Unit

How to Keep Your A/C Unit Running Efficiently

Chances are if you’ve neglected a spring checkup, your air conditioner isn’t cooling nearly as well as it could. A year’s worth of dirt and debris clogging the cooling fins, a low coolant level, a dirty blower fan filter and a number of other simple problems can significantly reduce the efficiency of your air conditioner and wear it out faster.

We’ll show you how to clean the outdoor unit (called the condenser) and the accessible parts of the indoor unit (called the evaporator). All the steps are simple and straightforward and will take you only a few hours total. If you feel this job is better suited for a professional call Morehart Air and Heating 623-566-0005.

You may have a different type of air conditioner or a unit mounted horizontally in the attic. However, you can still carry out most maintenance procedures we show here, because each system will have a condenser outside and an evaporator inside.


  1. Clean the condenser – Begin by shutting off the electrical power to the unit. Normally you’ll find a shutoff nearby. It may be a switch in a box, a pull lever or a fuse block that you pull out.
  2. Vacuum the fins clean with a soft brush. On many units you’ll have to unscrew and lift off a metal box to get at them. Check your owner’s manual for directions and lift off the box carefully to avoid bumping the fins. Occasionally you’ll find fins that have been bent. You can buy a special set of fin combs to straighten them.
  3. Unscrew the fan to gain access to the interior of the condenser.
  4. After you hose off the fins, check the fan motor for lubrication ports. Most newer motors have sealed bearings and can’t be lubricated. Check your owner’s manual to be sure. If you find ports, add five drops of electric motor oil. Don’t use penetrating oil or all-purpose oil.
  5. Clean the indoor unit – The evaporator usually sits in an inaccessible spot inside a metal duct downstream from the blower. If you can get to it, gently vacuum its fins with a soft brush as you did with the condenser. However, the best way to keep it clean is to keep the air stream from the blower clean.
    Begin by turning off the power to the furnace or blower. Usually you’ll find a simple toggle switch nearby in a metal box, otherwise turn the power off at the main panel. If you have trouble opening the blower unit or finding the filter, check your owner’s manual for help. The manual will also list the filter type, but if it’s your first time, take the old one with you when buying a new one to make sure you get the right size. Be sure to keep the power to the blower off whenever you remove the filter. Otherwise you’ll blow dust into the evaporator fins.
  6. The evaporator fins dehumidify the air as they cool it, so you’ll find a tube to drain the condensation. The water collects in a pan and drains out the side. Most tubes are flexible plastic and are easy to pull off and clean. But if they’re rigid plastic, you’ll probably have to unscrew or cut off with a saw to check. Reapply glue to the rigid tubes using a coupling, or replace them with flexible plastic tubes.

We here at Morehart Air and Heating like to provide our customers with as much knowledge as possible when it comes to your heating and cooling units. If you would like to clean your system yourself the tips are here. If you feel a professional is better suited we are waiting for your call. Here to help….Always.

How Inverter Technology Can Boost Efficiency

For the thousands of Valley residents whose homes are not served by natural gas, upgrading a heating and cooling system to one of the most energy-efficient technologies available today has been difficult to do.

But this year, that’s changing.

Up until now, highly-efficient inverter systems, which have reported power savings as high as 50 percent in energy-efficient homes – according to the Department of Energy’s Energy Star program – have been available primarily for gas furnace systems. Meanwhile, some electric heat pump owners have been waiting for these better systems to come to market.

Some brands have rolled out heat pump inverters, but their SEER (Seasonal Energy Efficiency Ratio) rating usually doesn’t top 17, says Josh Morehart, president of Morehart Air Conditioning & Heating, in Phoenix. However, on Jan. 1, Amana released its AVZC20 high efficiency heat pump, with inverter technology, offering up to 21 SEER performance.

“This is the next big step in [inverter] technology. We’ve actually had a lot of customers waiting for it.” Morehart added. “If your home was all electric, you really didn’t have an option like this in the past.”

Inverters and efficiency

The Department of Energy uses SEER ratings to measure the efficiency of heating and cooling systems. The higher the SEER rating, the lower the cost of operation and the greater the overall efficiency of the system.

Long used in Europe, inverters run on DC (direct current), as opposed to AC (alternating current) power. Using DC power with a variable-speed compressor allows the machine to only use the minimum amount of energy needed to increase the temperature in a space.

Morehart makes a comparison between a standard light switch and a dimmer. A traditional switch turns the bulb completely on or off, while a dimmer adds only the minimal amount of power needed to increase or decrease the illumination of a bulb.

“With an inverter, it’s never running full blast like what you see with older systems, and that really helps with energy savings,” he added.

Sound control, installation

Because inverters rarely work at full capacity to cool a space, the AVZC20 is also very quiet. The Amana system even comes acoustically-engineered with a compressor sound-reduction cover and high density sound control blanket. “People sit outside on their patio and don’t hear their own systems. Since so many homes are built close together here, they start to realize how loud their neighbor’s system is,” Morehart noted.

When shopping for inverter heat pump systems, the HVAC pro cautions consumers to buy from licensed dealers who have been specifically trained to install and maintain them. Trained installers know to watch for certain details that can help an inverter system perform at its peak, like, for example, assuring a system has proper clearances around it. They can even offer guidance on maintenance to help consumers maintain warranties and keep their systems working right.

With the AVZC20, Amana offers a lifetime warranty on the compressor. If an untrained or unlicensed dealer improperly installs the system, a homeowner could be in for a rude awakening if problems arise.

“Not all contractors are inverter contractors and not every Amana dealer is invited to sell these inverters,” Morehart said. “Training is absolutely critical.”

Why Amana and York are Leading the Way

York and Amana Lead the Way in Heating and Cooling

Whether you are looking for reliable heating during the cooler months or an air conditioning system that can meet the demands of a hot Arizona summer, no systems are as highly regarded as York and Amana. According to Consumer Reports, the heating and air conditioning systems (HVAC) produced by these companies are the top rated systems to own.

Here is some additional information about the York and Amana heating and cooling systems. The qualities that make them highly rated are why a vendor such as Morehart Air Conditioning & Heating installs these systems in homes like yours throughout the Phoenix area.

York Heating and Cooling Systems

York Heating and Cooling Systems has been in the business of providing heating and air cooling solutions for more than 140 years. Since 1874, this York, Pennsylvania company has been at the forefront of the HVAC industry, being the first company to create air conditioning in a commercial office in 1924. Users today of the systems developed by York include the Empire State Building, U.S. Capitol building and the famous Sydney Opera House in Sydney, Australia.

York’s systems are as suitable for residential use as they are for commercial buildings. They offer a variety of solutions for the home, including a furnace and air conditioner combination that not only provides heat and cooling but is also designed to humidify and dehumidify the home. There systems are energy efficient and built to withstand the climates, making them a durable, high quality appliance to consider.

Modern A/C Technology Shows Old Tech the Door

This summer, Robert Krein’s floundering home air conditioning unit was clunking and gurgling towards another expensive repair. It was becoming an annual occurrence for Krein, who openly regrets the purchase of a cheap system four years ago. So, this summer the Surprise retiree, and his wife, opted for something very different.

The Kreins purchased an Amana AVXC20 high efficiency air conditioner from Morehart Air Conditioning & Heating. At first thought, the make and model may mean little to a consumer who hears plenty of marketing noise out there about energy efficiency. But in his conversation with the Morehart team, one word caught Krein’s attention, and it was ultimately the dealmaker. That word was: inverter.

“I’m not a technical genius by any means, but I knew what that meant,” Krein recalled. “I knew it would be more reliable and run quieter.”

The DC power advantage

With the AVXC20’s inverter system, AC (alternating current) power is converted to DC (direct current) power – a more efficient and stable current.

From there, the unit relies on circuit boards to efficiently control the amount of electricity the system uses. The variable-speed compressor consumes the absolute minimum amount of energy needed to maintain a consistent temperature in the home, running more frequently, but using less wattage overall.

“Think of a dimmer switch on a light bulb, using the bare minimum amount of electricity,” adds Josh Morehart, founder of Morehart Air Conditioning & Heating.

A standard system, the A/C pro explained, operates a lot like a roller coaster, with peaks and valleys, using all the energy it can at once to achieve its goal of reaching a certain temperature programmed into a thermostat.

“This really is like the difference between a gas guzzling V8 and a Tesla (electric car),” Morehart noted.

DC and air conditioners

In the late 1800s, DC power was the go-to source in the U.S. DC electricity, which moves in one direction, however, loses power when traveling long distances. The more volatile AC current, which could move in many different directions, was better for long distance power transmission. So, America grew up with AC power distributed to its homes and businesses.

However, through the years, experts and consumers realized the more efficient DC current was better suited for home electronics and small appliances, particularly those with imbedded microchips and semiconductors. Cords that changed AC power coming into homes from the electrical grid to DC power for machines and appliances quietly became the norm. Think of your computer charger today; that’s an inverter that converts AC power to DC power for your machine.

Using inverters in air conditioning systems still hasn’t caught on in America the way it has in Europe and Asia, said Morehart. But Amana has been perfecting the practice in Europe for years, and it’s now making its energy efficiency case with A/C compressor inverter technology in the US.

“This, more or less, is going to be the standard. Solid State compressors will be phased out. This is what will help us meet stricter guidelines from the Department of Energy.” – Josh Morehart

20 SEER on a bad day

Krein is expected to save about 40 percent over an expected 15-year life for the unit, Morehart says. He paid a bit more up front, but between using DC power and other efficiencies built into the system, Amana third-party verifies that savings will pile up the moment Krein first sets his thermostat.

“This, more or less, is going to be the standard. Solid State compressors will be phased out. This is what will help us meet stricter guidelines from the Department of Energy,” Morehart added.

The Amana system comes with a 20 SEER (Seasonal Energy Efficiency Ratio) rating, well above today’s national minimum of 14. However, it’s important to note that the AVXC20 operates at 20 SEER when the air temperature hits 115 degrees. “The rest of the time it’s running at an even higher efficiency,” Morehart noted.

The product is getting favorable reviews, even though it comes with sticker shock during the sales process. Morehart draws a parallel to buying solar panels today.

“They see the price and they’re concerned, but if the math is explained properly then the customer understands what this can do for them,” he added.

For Krein, paying more now means spending less later, but also hearing a lot less today, too.

“The system is very, very quiet. The only thing you ever hear is the wind noise from the cooling fan. You never hear the fan motor itself,” he added.

A New Heating System for the Holidays

What’s on your Christmas list? How about investing in something that can really pay you back over time? We’re talking about a new heating system just in time for the holidays. If your existing home heating system is more than 15 years old, you’re very likely losing energy efficiency and paying much more than you should for electricity and fuel. Let’s take a look at the many reasons why a new heating system can benefit you.

Fewer Repairs

Just like anything else, as your heating system ages, components tend to break down. You may find yourself replacing parts every year or getting extensive maintenance done just to get it to work properly. These repairs bills are unexpected and can really eat into your household budget. A new system will cost you outright, of course, but at least you know you can rely on that unit to do its job when called on.

Efficient Airflow

A new heating system can boost the airflow through the ducts in your home, ensuring every room gets equal and adequate heat distribution. It’s this reliability that you can count on when you replace your old system with a new one. If you’re not getting the airflow you want, your old model could be on its way out. The efficiency of older furnace and boiler systems is only between 60 and 70 percent, compared with modern heating systems that can achieve efficiencies as high as 99 percent, according to This means your new unit is converting almost all the fuel to useful heat!

Increased Efficiency

Think of your heating system purchase as a long-term commitment that will pay off for many years down the road. You’re not buying a toaster oven here. According to HGTV, when you buy the highest energy efficiency rating possible now, you can avoid the high energy prices that come later.

Installing a new heating system is a great idea for the holidays. Having family to your home for Thanksgiving and Christmas and keeping everyone warm and happy is the gift that keeps on giving. Morehart AC has been serving the valley for many years. We will provide your home with a system made from some of our industry’s top heating manufacturers and give you a nice, warm home to relax in during the colder months.

Is a Heat Pump Right for You?

When it comes to heating your home, you have several options, but two of the most common choices are either a heat pump or a furnace. There are pros and cons to both, and the final decision depends upon the local utility cost comparisons for electricity vs. natural gas or other fossil fuels.

Here in Phoenix, where winter temperatures can get cold at night, it rarely makes sense to install a heat pump. Rather, homeowners can choose to adapt their gas furnace to a heat pump, called a hybrid heat system, to maximize energy savings during both extreme and temperate weather days.

Heat Pump Basics

A heat pump does double-duty, serving as both a heating and cooling unit. It is essentially a heat transfer machine. To heat your home, it extracts heat from outside air, concentrates that energy—thereby raising the temperature—and then transfers this energy to the inside of the structure. The process is reversed during the warm months, in which the heat pump essentially replaces the air conditioner. In this case, the heat is removed from the inside and transferred outside to accomplish the desired reduction in temperature we call cooling. Their compressors can be noisy, so they need to be installed properly and maintained by licensed HVAC technicians, such as Morehart Air and Heating.

When temperatures dip below 39° F during the nights, it becomes impossible for heat pumps to extract heat from exterior air, so the hybridized mini-furnace system kicks in using electric or gas-fired heating coils.

Geothermal Heat Pumps Increase Energy Efficiency

Eco-conscious homeowners also have the option to install geothermal heat pumps, which place the compressor deep in the ground where ambient earth temperatures are consistent. While the initial investment is steep, it pays for itself over time, providing reduced utility bills year-round. As of 2015, the government is still offering tax credits for qualifying geothermal heat pumps, which can further offset the investment.

To optimize the efficiency of a new heating and/or cooling system, contact Morehart Air and Heating. We’ll determine whether a furnace or hybrid heat system makes the most sense for your home.

How Air and Heating Got Their Start

For the first 100 years home heating in a heavily forested America was dominated by biomass (wood) and it was not until 1885 that the nation would burn more coal than wood. Prior to 1885 the majority of homes in America were heated with wood burning brick fireplaces and derivatives of the cast iron Franklin Stove invented in 1742.

By the end of the 19th century the invention of low cost cast iron radiators would bring central heating to America’s homes with a coal fired boiler in the basement delivering hot water or steam to radiators in every room. At about the same time, in 1885, Dave Lennox built and marketing the industry’s first riveted-steel coal furnace. Without electricity and fans to move air, these early furnaces transported heat by natural convection (warm heated air rising) through ducts from the basement furnace to the rooms above. These two methods would dominate home central heating until 1935, when the introduction of the first forced air furnace using coal as a heat source used the power of an electric fan to distribute the heated air through ductwork within the home.
In 1882, the first coal fired electric power plant opened in New York city delivering enough power to light 11,000 light bulbs and marking the beginning of the end for gas and kerosene lamps.

The heating and AC industry has certainly come a long way since the days of no temperature regulation. Let’s take a look at the history of both the air conditioning and heating industries.

Air Conditioning Units

In the early 1900s, the concept of air conditioning was still very primitive at best. Machines were invented that blew air over ice or cold coils to control room temperature and humidity, says Popular Mechanics. In 1902 Willis Carrier would build the first air conditioner to combat humidity problems inside a printing company and in 1917 the first documented theater to use air conditioning made its debut at New Empire Theatre in Montgomery, Alabama.

Between 1928 and 1930 the Chamber of the House of Representatives, the Senate, the White House, the Executive Office Building, and the Department of Commerce would be air-conditioned.It wasn’t until the early 1930s that individual units were designed to sit on the ledge of a window, which soon grew in popularity — at least with the rich. This is because the units were large and expensive, not very accessible to the masses. With the approach of 1940 came the first air-conditioned car. When 1953 rolled around, residential air conditioners were becoming more available to everyday folks thanks to the prosperity enjoyed by the country after World War II ended, with one million AC units sold that year alone. The 1970s saw the emergence of central air conditioning, making this the coolest way to control temperature throughout a home. Today, central air is still the preferred method of temperature and humidity control.

Heating Units

The very first heating options available to man came about, of course, with the discovery of fire. Fire pits, them chimneys and hearths were the primary way of keeping a home warm, although there was no effective way to distribute that warmth.

The Industrial Revolution brought about the invention of the first gas metering system for residential use, but not until the 1920s did the oil-burning furnace first make its debut. Electric-powered furnaces gained in popularity not long after that. Fast forward to today and you’ll see that nearly eight million homes in this country are powered by heating oil, electric or gas fireplaces.

At Morehart Air Conditioning & Heating, we’re experts at what we do – but we don’t expect you to be familiar with the terminology of the HVAC industry. We want to discuss some of the most important HVAC terms and acronyms used by HVAC companies today, with the hope of educating our current and future customers. By exploring the terms below, you may gain a better understanding of the details involved with a service call to your residence.

AFUE: This stands for Annual Fuel Utilization Efficiency. This term represents a rating reflecting the efficiency level when fuel is converted to energy via a gas furnace. A higher AFUE rating means greater energy efficiency. But unlike SEER, which has an arbitrary rating associated with it (like SEER-16, etc), AFUE is actually far simpler to read and understand. A furnace’s AFUE rating is listed as a percentage of how much fuel it can convert into usable heat, with a scale ranging from around 30-100.

BTU: BTU stands for British Thermal Unit, specifically, it is the amount of energy needed to raise 1 pound of water 1°F at sea level. A single BTU is equal to the amount of heat emitted by one wooden kitchen match. In terms of heating and cooling, a BTU is the measure of heat emitted by fuel or eliminated through cooling. A higher number of BTUs isn’t always the answer. Using any type of air conditioner, whether a portable unit, a window unit or central air conditioning, with a BTU level higher than needed can cause the unit to cool quickly, cycle off and then, to maintain your desired temperature, have to cycle on again soon after. By cycling on and off too many times, your air conditioner’s compressor will quickly over-work itself.

CFM: This is an acronym for Cubic Feet per Minute, which is a measurement for airflow. To calculate this properly follow these steps:

  1. Measure the length, width and height of the room, using a tape measure. Round all the values up to the next full foot, to simplify the calculations. For example, if a room length is 17 feet and 7 inches, round it up to 18 feet.
  2. Multiply the three values together to determine the volume of the room in cubic feet. For example, if the length is 18 feet, the width is 12 feet and the height is 10 feet, the room volume is obtained from the equation volume = 18 x 12 x 10, giving a room volume of 2,160 cubic feet.
  3. Multiply the volume of the room by the number of times the heated air is to be changed every hour. The result is the volume of heated air that passes through the room in one hour. For example, if the air is changed six times every hour, multiply the volume of air determined in Step 2 by six. Using the example data from Step 2, the result would be six times 2,160 cubic feet, or 12,960 cubic feet of air passing through the room per hour.
  4. Divide the value obtained in Step 3 by 60, the number of minutes in one hour. The result is the volume of air that must be passed through the room every minute. For example, 12,960 divided by 60 equals 216, so 216 cubic feet of air must be fed into the room every minute. The room requires 216 CFM for heating.

Compressor: The compressor is the core of a heat pump or air conditioning system. It compresses the refrigerant to get it to the right pressure and temperature before it passes through the condenser coil. If your compressor fails, your air condenser or heat pump will not be able to effectively make your house comfortable. The compressor is also the biggest energy-sucking part of your air conditioner or heat pump.

Condenser Coil: A coil changes refrigerant from vapor form to liquid form by causing heat to dissipate. After the gas refrigerant is pressurized and heated in the compressor, it enters the condenser coil. Here, two things happen. The gas refrigerant transfers its heat to the air blowing over it. Simultaneously, the refrigerant cools and turns into a liquid.

Energy Star®: Equipment that qualifies for this national program is much more energy efficient than standard equipment. As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home’s heating, ventilating, and air conditioning system can have a big effect on your utility bills.

Heat Pump: It serves to heat or cool the home, depending on the season. A heat pump is a device that provides heat energy from a source of heat to a destination called a “heat sink”. Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one.

HEPA Filter: Sometimes called high-efficiency particulate arresting or high-efficiency particulate air, is a type of air filter. This type of filter removes allergens in the air. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes.

HSPF: This means Heating Seasonal Performance Factor. The term is used to describe the measure of efficiency for a heat pump during a heating season. The higher the HSPF rating of a unit, the more energy efficient it is. HSPF is a ratio of BTU heat output over the heating season to watt-hours of electricity used.

HVAC: An acronym for Heating, Ventilation, and Air Conditioning.

Hybrid Comfort System: A hybrid system is a combination of a gas furnace and a heat pump.

Matched System: In this type of system, all of the components are equally matched in terms of efficiency and capacity. The cooling components consist of an outdoor condensing unit and an indoor air handler. The two components are designed to work together to provide optimal performance, maximum efficiency, and comfort. When a new outdoor condenser is installed, you should install a new, corresponding and equally efficient indoor air handler at the same time. The installation of the two components that are designed to be used together comprises a matching system.

Modulating Heating: This kind of system continuously adjusts the temperatures in a building or home as they change. Unlike single-stage gas furnaces that operate ON or OFF, a modulating, variable-speed gas furnace minimizes energy use by running at the lowest possible fan speed, and producing just the right amount of heat to keep a steady, comfortable temperature in your home.

NATE: An acronym for North American Technician Excellence, which is the only certification program recognized nationally by the entire HVAC industry.

Packaged System: This is a heating and/or air conditioning system that contains all of its components in a single cabinet.

Refrigerant: This substance helps to create cooling, and it’s used with most cooling systems and units.

SEER: This means Seasonal Energy Efficiency Ratio, a rating that reflects the measurement of cooling produced by an air conditioner or heat pump.

Split System: This is a system with components in dual locations, such as one with a furnace indoors and an air conditioner unit outdoors.

Diagnosing Different Air and Heating Issues in Phoenix

Ensuring Air and Heating System Efficiency

As a homeowner in Phoenix, you need to ensure that everything is in order and that your air and heating system equipment used at your home is functioning properly. If your heating and cooling system isn’t working as efficient as it’s supposed to, you ought to look for solutions early enough before a minor issue becomes a major one. One piece of equipment you need to check and ensure is in good working condition is your heat pump. There are several ways to determine if the heat pump needs to be repaired. Some of these ways include:

Look Out for Foul Odors

Heating components tend to have a dusty scent in the first few months or years of being used. This is quite normal but you should be sensitive to any other smell as it could signify AC failure. Foul odors indicate possibility of open tears enabling the system to suck in air from the crawl space or bacteria built up within the air duct system. Even if the odor is not intense, this is something that you should not ignore. The last problem you need every time your air kicks on, whether air conditioning or heating, is bacteria getting blown into your homes air for you to breath.

Check These Out

Abnormal Sounds

You know the obvious sounds from your heating and AC components but if you notice any sound that is abnormal such as grinding, clanging and squealing, you need to call a professional because those could be signs of even bigger underlying problems.

Strong Air Flow, Poor Cooling

If you notice that your air conditioning components are not cooling your home yet there is still strong air flow, it could be the right time to call an air and heating technician. However, before you do, ensure that you confirm that the thermostat has not been set on fan only mode which could be the result of poor cooling. It is very important to have your cooling and heating components inspected in case of a failing compressor, which can be expensive to replace especially if not repaired during the early stages of a problem.

Weak Air Flow

This is another sign of a faulty air and heating system. It could be a result of damaged ductwork, debris inside the vent or a closed register. However, before you contact a technician, clean the air filter and recheck everything. You don’t want to make a phone call to have an HVAC contractor out to your home just to tell you that your air filters are too dirty and are restricting air flow. Changing your air filters every 30-45 days will ensure this minor problem is prevented.

Leakage Near the System

Every heat pump requires the drainage of moisture. If the drainage is not well controlled, water will accumulate near the system, in the pan near the heat pump. Some of the major causes of system leaks include clogged drain lines or a frozen control regulator. Apart from the leaks near the system, you also need to watch out for leaking refrigerant. A professional HVAC technician from Morehart Air Conditioning and Heating will be able to diagnose this and inform you of the proper solution.

Won’t Change Modes

This is usually a problem with the heat pump reversing valve when it gets stuck between modes. You need a technician to determine what measures to take because it could be a problem with the solenoid.

If you have noticed the above signs or anything that is abnormal with your heating or cooling systems, you need to contact a licensed and professional technician from Morehart.
