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.

At Union Services, we provide all the services you need to keep your AC running in top-notch shape. Call us at 704-288-0812 for repairs, maintenance, or new-system installation.

Air Conditioner Installation in Indian Trail, NC 28079

“I’m very satisfied with the ac unit and heat system. Very professional people. Thank you so much to all of them.”– Daisy M.

They Did a Wonderful Job

“Had our A/C replaced and everything went wonderfully well– and the new system is working great. Thank you for sending out two great servicemen. Please tell them that they did a wonderful job.”

– Cindy E.

Very Pleased

“I had two Heating & A/C systems replaced. I’m very pleased with the professional way this was performed by Matt, Craig, Chad, and Marc. Very neat, clean, and professional job.”

– Jim D.

We Plan to Use Only Union Services From Now On

“We plan to use only Union Services from now on. One of our air conditioners (purchased from another company) was not blowing cool air. We called Union Services and that day a Technician was sent to check the unit. He found loose wires. After reconnecting the wires, we were good to go. Separately, last year we purchased a new unit from Union Services and were pleased.”

– Linda K.

Impressive on all Counts!

“Union Services’ professionalism on all counts–– whether maintenance or system replacement–– has been impressive! We began using Union Services for our home’s Heating & A/C system maintenance in 2015. By then our 9-year-old builder-installed system was needing frequent attention. We decided to fully replace our downstairs system this spring. We have a sealed crawl space, which reduces airflow and causes the units to operate inefficiently–– something only Union Services was able to point out. They performed a very professional job installing a vent pipe to prevent our units from working so hard. Due to a small access door, there was some damage to a seal in our crawl space–– but we were thrilled that this was immediately addressed by Union Services without our having to exchange multiple phone calls and emails.”

– James & Natalie F.

Amazing Job From Start to Finish

“The Union Services guys were very professional and friendly–– that’s what made the process go smoothly. They did an amazing job from start to finish installing my new Heating & A/C system.”

– Edward R.
