What Makes a Heat Pump the Best Choice for Home Comfort?

Monday, October 16th, 2017

dog-home-comfortEvery home has unique heating and cooling needs, requiring a different system for homes of different shapes and sizes. The biggest heating system or cooling system is not necessarily the best. In fact, choosing an air conditioner or heater that is too large for your home can result in short cycling—the system running too often and wearing down its parts. And of course, a system that is too small will not do a sufficient job of heating or cooling your home.

While homeowners will choose different efficiency ratings for their comfort systems based on what they can afford, and while sizing changes based on the size of the home, there is still one type of system we recommend time and time again. In our area, the heat pump is the way to go.

A New Thermostat Makes Your HVAC System Easier to Use

Monday, November 28th, 2016

An article in the Washington Post reveals that many people do not really know how to operate their thermostats. The traditional digital wall thermostat can be difficult, especially if you inherited it with the home and you’ve never had a technician walk you through it.

In addition, many older thermostats can have a lot of limitations. An older thermostat may not allow you to make variations in the temperature schedule from day to day, even if your work schedule varies. If this is the case in your home, or if you’ve ever had trouble figuring out the programming on your system, it may be time for a change. A new Wi-Fi thermostat can make things so much easier!

Selecting a Heating System for New Construction

Thursday, January 8th, 2015

Building a brand new home can be an exciting undertaking, but some of the decisions you have to make in the process can seem daunting. Choosing a new heating system for installation is one of those difficult decisions, but it can be made much easier if you choose professionals to assist you along the way. For now, you may simply be wondering what type of unit is best for your new construction, so we’ve made a guide to a few of the most common systems used for heating in Rincon, GA.


Furnaces are some of the most common heating systems installed in homes today. Furnaces are reliable and effective, and today’s models are safer and more efficient than ever. Modern furnaces have many kinds of added safety features to prevent any potential gas leaks and protect the furnace from faulty operation. Today’s systems are also extremely efficient; all have an AFUE (annual fuel utilization efficiency) of 80% or greater, an improvement over those built decades ago that had an AFUE of about 50%.

Heat Pumps

Heat pumps use the same technology used for heat removal in air conditioners to bring heat into a home. Refrigerant moves through the system, removing heat from the outside air (even when it is very chilly outside) and transferring it to the air handler indoors. In the summer, refrigerant reverses to move heat outside. This is an efficient heat source, as it moves heat around instead of generating it, and it can be used in place of a separate AC and heating system.

Geothermal and Water Source Heat Pumps

A geothermal heat pump is partially buried underground, so building a new home presents a great opportunity for installation. Because the temperature underneath the earth stays relatively stable, heat is always available, and it’s one of the most efficient ways to move heat from one area to another. Water source heat pumps instead use water as a starting point for the heating process, and either unit can save you a lot of money over time.

How a Malfunctioning Thermostat Can Impair Your Heating

Monday, March 3rd, 2014

Your heating system is a vital part of your Hilton Head, GA home. Despite our mild Southern winters, we get our share of cold nights, and without a proper heater, you’re apt to feel the chill far more often than you should. Heaters encounter problems from time to time of course, and when they do, you need a reliable service to handle them. But not all those problems stem from the heater itself. The thermostat, which controls when the heater turns on and off, can wreak havoc with your household comfort levels when it breaks down. Here’s how a malfunctioning thermostat can impair your heating.

The thermostat can’t do its job unless the timer works properly and it can accurately read the temperature in the house. Furthermore, it needs to be able to trigger the heater at the right time and turn it off when temperatures reach their stated levels. If one of the internal components develops a fault, it can’t do that. Suddenly, your ability to regulate the temperature is gone. Either the heater won’t turn on when it should, or it will run much longer than it should. Either way, it prevents your home from getting the heat it needs, resulting in temperatures that are either to hot or too cold.

The same thing can happen if there’s nothing actually wrong with your thermostat. If it’s placed in the wrong location in your home – near a draft, say, or too close to an outside door or window – then the temperature it reads will not accurately reflect the temperature in your home. The result is very much the same, with the heater turning on when it isn’t supposed to, not turning on when you need it to, turning off too soon or not turning off until your home is baking like a sauna.

Though a malfunctioning thermostat can impair your heater, a good repair service can restore it to normal. For problems with heating in Hilton Head, GA, call on the experts at AAction Air to help. We’re skilled in repairing and replacing faulty thermostats, and we can perform the operation with professionalism and care. Call us today to set up an appointment!

Problems Caused by a Dirty Furnace Filter

Monday, February 3rd, 2014

Furnaces contain filters designed to keep dirt, dust and other build-up from interfering with its functioning. It’s an important role, which is why you should change your furnace filter on a regular basis in order to keep it functioning as it should.  If you don’t change it, your furnace can develop serious issues that only a qualified Savannah GA heating repair technician can correct. Here’s a short list of the problems caused by a dirty furnace filter.

  • Clogged parts. The burners on your furnace can get clogged with dirt and grime, causing them to perform fitfully or not at all. This can severely restrict your heater’s efficiency, costing you more in monthly bills as it struggles to make up for the shift.
  • Friction on moving parts. Dust and build-up can increase friction on moving components such as the fan motor. That forces them to work harder and increases the chances of a breakdown in the bargain.
  • Reduced air flow. A dirty air filter restricts air flow through your system, and this can cause inadequate heating and can possibly lead to your furnace overheating. Once again, this means the furnace won’t function the way it needs to, and your bills will go up accordingly.

You can prevent problems caused by a dirty furnace filter by changing it often — once every three months at least, and even more frequently if you or a family member suffers from allergies. Furthermore, a regular maintenance visit from a trained professional can clean off dirty parts, as well as tightening loose fittings and ensuring that the furnace is functioning at peak capacity. If you need heating repair in Savannah, GA, you can count on the experts at AAction Air. We’re dedicated to keeping your furnace running as efficiently as possible, so give us a call to set up an appointment today!

3 Myths about Heating

Monday, January 27th, 2014

Heating a home has as many myths around it as anything else. We’ll address three of the most prevalent myths about heating that we encounter in our work. When you have questions about heating in Savannah, GA and want to get to the truth and the repairs you need, call us at AAction Air.

1. Setting your thermostat lower will always save you energy

While in theory, turning down your thermostat will save energy in heating your home, it actually depends on your heating system. With heat pumps, you want to be sure to use the electric resistance coils as little as possible, and letting your house cool down too much during the day might cause them to turn on to restore your home to a comfortable temperature when you get home. Thankfully, there are thermostats that are specially designed to work with heat pumps that take their unique operation in mind and allow you to save energy.

2. Heat pumps will not work effectively in winter

Heat pumps work both as air conditioners and heaters, but their efficiency rating for heating is lower than for cooling. However, unless you live in an area where the temperature drops far below freezing during the winter (certainly untrue for Savannah), you won’t notice a difference in the effectiveness of the heating from a heat pump.

3. Gas furnaces are dangerous

If this is rephrased to “Gas furnaces can be dangerous,” then it is no longer a myth. Any system that uses natural gas can pose a safety risk. However, hairdryers can be dangerous, as can toasters and electric holiday lights—if they are used incorrectly. The same applies to gas furnaces; if given proper maintenance and prompt repairs, a gas furnace poses no greater danger than an electric furnace or a heat pump.

AAction Air has many years of experience and a staff of NATE-certified technicians who know the truth behind the many myths surrounding home heating in Savannah. When you need repairs, maintenance, or simply advice, contact us: we’re available 24 hours a day.

Are These Noises from My Heating System Normal?

Monday, January 20th, 2014

All heating systems will produce some level of noise, although a few operate so quietly that you will hardly ever notice them. One thing all heating systems have in common when it comes to the sounds they make: any noise that is unusual—something you don’t normally expect—is usually a warning sign that the heater requires professional repairs.

We’ll go through some of the more “common” uncommon sounds from a heater that indicate trouble. For quality repairs on your heating in Hilton Head, SC, contact AAction Air. We have 24-hour emergency service to make sure your heater keeps working for you.

Noises that May Indicate Heating Problems:

  • Booming or rumbling: This is a sound you may hear from gas furnaces, whether a standalone unit or as part of dual fuel hybrid system. It usually indicates trouble with the burner. The usual problem is the burner has too much dust or debris on it, or possibly rust flakes, and it’s preventing the gas jets from coming on. This is something that requires immediate attention; shut off the gas power to furnace and call for repairs. Another cause for a booming sound—and this applies to any HVAC system that uses ductwork—is the ducts expanding from the heat. The sound will usually only happen when you turn the heater on at the start of the season.
  • Rattling: Sometimes this issue is as simply as loose bolts on the cabinet of a furnace or heat pump. However, if the sound seems to be coming from the inside of the cabinet, it likely indicates a damaged, broken motor. The motor parts are rattling around, and the motor will soon stop working entirely. Motors need professional replacement when they burn out. The rattling sound could also be a fraying blower motor fan belt, in which case it is probably on the way to breaking away entirely, which will result in it striking against other components in the cabinet.
  • Shrieking: High-pitched noises are often warnings in furnaces and heat pumps that the motor bearings are dirty. This will eventually cause the motor to burn out.
  • Clicking: For heat pumps, this is probably a failing capacitor, which will need a replacement.

Go with the Professionals

Repairing a heating system safely and effectively is a skill that requires years of training and experience. Don’t try to open the cabinet of your heating system an attempt repairs on your own, and don’t rely on unlicensed amateurs to perform the work. Only professionals can do the work accurately and in a timely fashion, leaving you with an effective and safe heater.

When Should I Call for Heating Repair?

Monday, January 13th, 2014

The Georgia winter can contain a few cold and uncomfortable surprises, especially if you have a heater that is on the fritz. To make sure you have an enjoyable season here in Savannah, GA, schedule heating repair as soon as you think you need it. The longer you wait, the more likely that the problem will grow worse and become a more extensive and expensive repair.

Here are some tips from AAction Air to help you know when you should call for heating repair in Savannah, GA. We are ready 24/7 to help you with any of these issues.

Signs to call for heating repair… now

  • Loud and strange noises – You should have a good idea of the sort of sounds your heater makes during normal operation. If an abrupt and unusual sound interrupts this harmony, it usually means there is a major malfunction somewhere inside the heating system: dying motors, broken fan blades, cracked heat exchangers. Although the noise might have an innocuous source, don’t take that risk: call for professional repairs.
  • Foul smells from the vents – If you have a forced-air heating system that uses ductwork (furnace, heat pump, geothermal), any odd smell coming from the vents is a warning sign of trouble. The issue might be with the ducts, although an acrid odor could point to a burnt-out motor.
  • The heating system won’t turn on – …and you’ve already checked the thermostat and the power supply. If you can’t account for the failure of the system to turn on, don’t wait and hope that it will resolve itself in a few hours on its own, because it won’t. You need repair technicians to get to the bottom of the problem.
  • Your heating bill takes a sudden, unexpected jump – You can expect an increase in your heating bills at certain times of the year, but if you can’t account for a sudden spike in energy use, it could mean a repair need in the heater is making it work harder than it should.

Why you need expert repairs

There’s a running theme with all of the above warning signs: none of them have a single cause behind them. You need to have trained experts in HVAC technology investigating your heater to find out what needs attention. Attempting to troubleshoot these problems on your own could result in damages, or worse, injury to yourself (this is a major concern with natural gas-powered heaters). When you need repairs, call licensed experts.

AAction Air has trained technicians on call 24 hours a day to make sure your heating repair in Savannah, GA  is taken care of quickly. Call us today for superior service.

Causes of Cracked Heat Exchangers

Monday, January 6th, 2014

Gas furnaces are old standbys of the heating world for good reasons: they supply affordable warmth and can last for many years. However, as with any system that runs on natural gas, they have potential safety issues. One of these is a cracked heat exchanger.

Modern natural gas furnaces are built with safety as the main concern; malfunctions that can cause safety problems are very rare. With proper maintenance and the help of professionals, like those at AAction Air, your gas furnace in Rincon, GA should provide you many years of efficient heating.

The heat exchanger

The heat exchanger resembles a metal clamshell. It does the vital job in a furnace of transferring heat from the combustion gas to the air that then circulates through your home. After the heat transfer, the combustion gas inside the exchanger is safely vented through an exhaust flue to the outside. Should the heat exchanger develop any cracks, the high heat from the combustion gas will cause these small gaps to spread open and allow combustion gas to escape into the cabinet instead of through the flue.

The main reason for cracks appearing in heat exchangers is corrosion. People often think that their furnace can’t develop corrosion or rust because the furnace doesn’t use water. However, corrosion can occur because of the reaction between the combustion gases and the metal of the furnace—especially if the furnace isn’t venting properly. Moisture from the ducts can also enter the furnace, and if (as is often the case) the air conditioner unit is mounted above the furnace, leaks in the AC will quickly promote rust inside the furnace.

Corrosion weakens metal, and because the high heat inside the heat exchangers causes them to expand and contract, the weakening with soon lead to cracks and the escape of combustion gas. Combustion gas is dangerous: it is carbon monoxide, which is colorless and odorless—as well as toxic and highly combustible. Cracked heat exchangers need to be replaced as soon as possible.

Call for professional repairs

Carbon monoxide leaks are difficult to detect, which is why we advise homes with gas appliances have CO detectors installed. Another warning sign of a cracked heat exchanger is unusual sounds from the furnace, such as rattling or clicking. You should never try to fix a gas furnace on your own because of the potential risk of further CO exposure. This is a job for licensed and trained professionals only.

AAction Air has 24/7 emergency service for when you’re worried that cracks in heat exchangers, or any other issue with your gas furnace. Call us any time you need help with your furnace in Rincon, GA.

Why Your Heater Keeps Shutting Down Prematurely

Monday, December 16th, 2013

Your heating system seems to be running fine: it comes on when it should, without making any strange noises, and starts providing you heat. But there’s one problem… it keeps shutting off too early, before it can reach the temperature set on the thermostat.

This problem is known as short cycling, and it’s a malfunction that we see often in heaters. It usually requires repairs, or sometimes a new installation. When it comes to heating Hilton Head, SC, AAction Air is a trusted name for quality; call us if you start to encounter “short cycling.”

There are a number of different reasons for premature shutdown of your heater. From our experience, these are the two most common:

An improperly sized heater

If your heater is too large for your home, it will raise the temperature rapidly and reach its target temperature too fast, shutting itself off before it can complete its cycle. This can turn into a serious problem since it will 1) drain extra power each time it has to turn back on, and 2) wear down faster, leading to more repairs and potentially an early replacement. Check with a professional HVAC technician to see if your heater is the wrong size.

An incorrectly calibrated thermostat

It’s easy to overlook the thermostat as the source of a problem, but it often is. The thermostat switches the heater off when it senses that it has met its temperature goal. But if the thermostat has become miscalibrated so it senses the temperature incorrectly, it may shut the heater off before it reaches its target. This is usually an easy fix for technicians.

Whatever has caused your heater to short cycle, it is an issue that needs remedy as soon as you can arrange it. If the heater continues to malfunction this way, it will lead to uneven heating and cause the system to age rapidly. Have an expert inspect your heater and find out what is wrong.

AAction Air has NATE-certified technicians on staff to provide you with a knowledgeable assessment of your heater’s needs. We offer customer service 24 hours a day, 7 days a week, so help is always available for your heating in Hilton Head, SC.
