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.
AC Facts
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.
SEER
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.

did their own problem solving when they could. They were here quite a long time and I got a good look at how they worked together and how neither one took over or ignored the other. There was clearly a leader but he didn't take over the job and leave the other standing around. Because of their cooperation and clear communications with their boss, the problem was solved smoothly and everyone involved was satisfied.
The best team I have ever observed. I just had to tell somebody that could appreciate what I just witnessed. I'm sending this same message to their boss. He ought to know.”
“Awesome! The guys were prompt, prepared and finished the job leaving the area very clean. Patiently answered any and all questions we had.
