What’s Wrong with Your Heater’s Ignition System?

Monday, February 1st, 2016

Today, standing pilot lights—ignition systems that rely on a steady flame at all times during the winter—are no longer in widespread use. Standing pilot lights aren’t used in new manufacturing, and electronic ignition, in which the burners heat up only as needed, has taken over.

How Does My Gas Furnace Work?

Monday, January 18th, 2016

The furnace may be the most common heating system used in the country, but that doesn’t mean homeowners are familiar with its operation. Furnaces are a mystery to many (especially in our area, where warmer weather calls for infrequent use). And due to the complexity of these systems, you should only allow a professional to service your gas furnace whenever you need repairs or a replacement.

A Few Common Furnace Repairs

Friday, January 2nd, 2015

Furnaces are the most common type of home heating system in the country. This means that furnace problems also happen to be the most common type of home heating problem. Since it is likely that you either own or will own a furnace at some point during your life, it pays to know a bit about the kind of repair needs furnaces can run into. Let’s examine some of them.

Broken Fan Belt

The fan belt is a rubber loop that connects the air handler motor to the fan. When the motor turns on, it uses the fan belt to actually turn the fan and circulate the air. Over time, the fan belt stretches and cracks from the stress of regular usage. Eventually, it can snap and render the fan unable to turn. You can tell that the fan belt is failing by the squealing sound that happens when the furnace turns on. If your furnace is on, but air doesn’t seem to be circulating, it is possible that the fan belt has already broken.

Faulty Pilot Light

The pilot light is a small, continuous flame responsible for lighting the burners and starting the furnace. Every once in a while, the pilot light may blow out and have to be relit. If the pilot light is refusing to stay lit, however, you may have a more serious problem. In older furnaces, the likely culprit is the thermocouple. The thermocouple is the part that senses when the pilot light is lit, and allows fuel to be supplied to it to keep it burning. A faulty thermocouple is one that has lost the ability to sense the pilot light, and so never opens the gas line to supply fuel to it.


Furnaces can overheat for any number of reasons, but the most common cause is actually the one most homeowners never expect. When the furnace’s air filter is not replaced often enough, it can become clogged with dust and debris, blocking air flow into the furnace. This traps heat inside the furnace itself, causing it to overheat and shut down as a safety measure. You can tell that your furnace is overheating when it starts turning itself on and off rapidly throughout the day, which is called “short-cycling.”

Furnaces vs. Heat Pumps

Monday, November 11th, 2013

For heating in Savannah, GA during our mild but unpredictable weather, furnaces and heat pumps are two of the most popular options. Furnaces have a long history, and chances are good that you’ve spent much of your life, from childhood through adulthood, with a furnace keeping you warm. Heat pumps are newer devices (although they also have a good bit of history behind them) that have moved from the world of commercial use and into homes during the last fifty years. For this upcoming Savannah heating season, which one will provide you the most effective and efficient performance?

There is no standard answer to that question, because excellent home heating requires balancing many factors, starting with a home’s size and its insulation. What we can do for you here is provide the basic pros and cons of both systems to give you a start in thinking about the direction you want to go for warming your house this winter.

When you need expert guidance—and you will when you see how many options you have—contact AAction Air.


Furnaces have run on the principle of burning fuel to heat air since their creation. Modern home furnaces rely on electricity, natural gas, or propane, with natural gas being the most popular option because of its relatively lower cost than other fuels. Furnaces are flexible; you can find one to fit most homes. If you already have a furnace in your house that you want to replace, a second furnace can be installed with few problems. Older furnace models often had poor energy efficiency, but newer ones score high AFUE (annual fuel utilization efficiency) ratings that make them competitive for energy savings.

Heat pumps

As a general concept, “heat pump” means any device that removes heat from one location and releases it to another. When used in the modern HVAC world, the term refers to a comfort system that combines a heater and air conditioner: it can reverse the flow of heat exchange to keep you cool in summer and warm in winter. This is the heat pump’s biggest advantage, a two-in-one comfort deal. Heat pumps don’t have to rely on burning fuel and they run entirely on electricity. But they have the drawback of working less effectively as heaters than as air conditioners. Considering the mild winter climate in Savannah, this is rarely a problem.

Getting a new heating system installed should start with a trained technician performing a heat load calculation on your home to arrive at specific idea of what type and size of heating system will do the best job for you. Whether a heat pump or a furnace ends up as your No. 1 choice, you can count on superb installation from AAction Air. Call us today!
