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.

A Very Professional Operation

“From the time Ryan gave us an estimate to the completion of the installation of the new Daikin AC and gas furnace by Dustin and Abel everything proceeded smoothly. The old AC and furnace were removed cleanly. The new furnace and AC are functioning flawlessly. A very professional operation.” – Deon E.

We highly, highly recommend ACS for AC service and installations

We highly, highly recommend ACS for AC service and installations. We have been in Marana for over a year and purchased a wonderful, relatively new (4 years old) home but with a faulty designed AC system. The builder touted the home as a two zone system but installed a one zone system that has failed at least twice and has never cooled the house to our comfort level.
Having tried several AC companies, we found ACS when we came home to a 95 degree interior temp on a Sunday. Called them for emergency after-hours service and they fixed the problem.
Recently decided to upgrade our overall system and again called ACS to suggest solutions and provide a bid. They recommended a Daikin multi-split system to create a true two zone system using our existing duct work. Very, very satisfied with their solution and cannot recommend them more highly.

I purchased a Daikin system

I was searching for a new AC/ gas heater unit and my friend recommended ACS. He said he had an excellent experience and received a competitive price. I included ACS in the bid process and they were very competitive for my system as well. The instillation was very professional and their attention to detail sort of blew me away. I purchased a Daikin system and I have been very satisfied. My house has two complete systems and ACS just finished the install of my second system (6 months later), which is proof that I an satisfied. M. Henry, Tucson Dec. 2017
