A short word from Jim at Airforce Heating & Cooling

Reliable AC Repair, Maintenance and Tune-ups

Investing in regular tune-ups helps to ensure that your air conditioner will remain working at peak performance.

AC System Basics

When air converts to a gas (in a process called phase conversion), it absorbs heat.  Air conditioners exploit phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils. The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm air over the cold, refrigerant-filled coils. Central air conditioners have a whole system of ducts designed to funnel air to and from serpentine, air-chilling coils.

When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils, and a second fan. As the gas cools, it changes back to a liquid, and the process starts all over again. Think of it as an endless cycle: liquid refrigerant, phase conversion to a gas/ heat absorption, compression and phase transition back to a liquid again.

There are two distinct things going on in an air conditioner:  Refrigerant is chilling the indoor air, and the resulting gas is being continually compressed and cooled for conversion back to a liquid again.

Condensation Problems in an Air Conditioner

A number of issues can cause the water in the condensate pan to begin to build up.  The line can become dislodged or something may have blocked up the drain. When this occurs, the condensate pan will start to overflow and spill into your home.  As a result, water damage can become extensive and may lead to significant repairs.

High humidity encourages growth of mold and mildew. These bacterial contaminants contribute to damage such as mildew, and also release toxic spores into the air, lowering indoor air quality.

Last but not least, standing water that results from condensation will start to increase your home’s humidity, causing additional discomfort and makes the system work more difficult.
