Air Conditioning Basics
The four main components to your air conditioner are:
Condenser: The condenser is the outside metal unit and where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.
Compressor: The compressor is inside the condenser. It circulates the pressurized refrigerant, to concentrate the heat, and changes the low pressure gas to high pressure.
Evaporator: The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.
Expansion Valve: The expansion valve controls the amount of refrigerant in your system.
All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.
An air conditioner doesn’t create cool air.
What happens in the AC process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.
Your AC will remove humidity.
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.
Your air filter needs to be checked and replaced every three to six months (depending on the manufacturer’s recommendations).
A dirty air filter restricts your air flow, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair.
Maintenance, maintenance, maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns over all.
The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.
At AA-AIR Company, we provide all the services you need to keep your AC running in top-notch shape. Call us for repairs, maintenance, or new-system installation.

“Kevin and Travis installed a new HVAC and completely new ductwork throughout my almost 100 year old home in Historic Old North Knoxville, and it was no easy task! Despite the challenges, their work was flawless, and I couldn't be more thrilled with my new system. I've had quite a bit of work done on my home in the past few months, and Kevin and Travis of AA-AirCo are by far the best service providers I've experienced. Kevin and Travis are extremely knowledgeable and tireless workers, not to mention quiet, respectful, and meticulous. Installing my system was a big messy job, but they made it look easy and left my home spotless. THANK YOU!”

“Philip recently serviced our system in my shop building. It had stopped running completely on a very hot day… the service was prompt… the very next morning. Philip got our system running again, needed a new part. The system runs better on these hot days than it has earlier this summer. Not only did Philip get us up and going again, he helped me with a woodworking problem I had been having. Good job all around Philip, and thanks! Your suggestion of a bit extender did the trick!”
