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.

“Our air conditioner stopped working on on one of the hottest days of the season. We were told probably couldn't get anyone here until 4 pm. We went to buy a window unit to get us thru until they could get here. Jake called before we got home and said he was on his way. He was here repaired the unit and gone by noon. He was very professional and friendly and is our Hero.”
“Jason was fantastic. Very kind and had no issues.”

Thank you”
“We had an issue with our unit that Central City installed about a year ago. Apparently had a bad board from the factory. Wayne quickly made the diagnosis, ordered the part for us and came back and installed it. Super friendly. Answered all my questions and made friends with our dogs. Great service.”
“Brad, Garrett and Ryan installed a new heat and air unit at our house today. They were professional, courteous and knowledgeable. We love Central City Heat & Air. Highly recommend.”
“Had the routine inspection service for my 2 AC units performed in late April. Came back from travel this week (5/23) and found the the downstairs unit hadn't been running for some time (temp well above setpoint on t-stat). Inspected the unit and found the blower cabinet door was sitting in place but not latched. Observed electrical tape had been used on the interlock switch so the unit ran following the inspection visit. All stopped when the tape let go. I put the cabinet door in place and latched it – system op resumed. The initial installation was very good as have subsequent maintenance checks over the years. This was not the expected quality service I paid for…”
“Raining heavy. They still came. Had to make a trip to Knoxville for parts. They did. Came back quickly and repaired unit. Did I mention it was raining heavy. Well actually it was pouring! Good job! Thanks to all of you ! I have ordered snow! Lol”
“Doug did a great job in servicing my HVAC unit this past spring. Thanks Matt!”
“Our air conditioner was not working, and tech Steve was sent over to take a look at it. He was EXTREMELY thorough, and it was evident that he knew what he was doing. He quickly diagnosed the problem and got our air conditioner back up and running. For all our future maintenance, Steve is the one we will ask for.”
