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.

“I am a LoneStar comfort club GOLD member.
The plan includes "Repair Warranty" 2 years.
Outdoor unit capacitor was replaced, though still working, due to "out of compliance capacitance".
This capacitor clearly stated, "5 year unconditional warranty" AND was installed by Lone Star less than 2 years ago.
I was invoiced for a $133 WARRANTY PROCESSING FEE. There is no "*" noted on the protection plan indicating a "FEE" for "WARRANTY" work.
To make matters worse the capacitor was replaced with the "same" manufacturer's capacitor. Might be looking at another failure in less than two years!!!!!
I suspect I'd have been better off not paying the protection plan, capacitor failing and having another service provider fix it.
PS
The only reason for a 2 star vs. 1 star rating is that the tech, Keldon, did excellent service work and confirmed LS comfort services management recommended replacing the still functioning capacitor.”
