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.

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.

How Much Money Can a New Air Conditioner Save You?

Our SEER2 (Seasonal Energy Efficiency Ratio 2) energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit’s SEER value and compare it to a newer, more efficient SEER2 unit. You can even customize it to better match your home’s system for a more accurate calculation.

“A few weeks ago our AC wasn’t working. Tim from JL Anderson came & repaired it. No problems worked well through all the hot days. Fast forward to last night, the house seemed warm. The AC wasn’t working. Marty was here this morning & it was our capacitor. Since we had a service earlier, that fee was waived. We’re running cool & happy that we choose JL Anderson!”

Whole System Replacement in Zionsville, IN, 46077

“After getting bids from several companies, I knew that J.L. Anderson was the best company to totally replace my furnace, air conditioner and humidifier. Starting with Kirt Bunch, the fabulous Consultant who came to my home to present the system to me. I couldn't have asked for a more
professional, knowledgeable and courteous young man. He answered every question I had and provided me with great incentives and a fabulous
new Trane System. Bret Leslie was my lead technician along with Dentrell Parker. Bret was outstanding, professional ever so courteous. He worked mainly in the lower level of my home and Dentrell was outside. They covered all of my hardwood floors and carpets. I honestly hardly knew that they were working inside and outside of my home. Mine was a 2 day job and they left my home in perfect condition. There wasn't a sign of any debris, dust, etc., just a brand new system which I am already enjoying. I must also mention that my air conditioning went out about a week before they were scheduled to replace everything. I called Kirt and he came out and got my unit working on a temporary basis so I could have coolness and moved up my installation date. With customer service being at a premium these days I am incredibly pleased with Kirt, Bret, Dantrell and J.L. Anderson Heating & Cooling.”
