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 Montgomery HVAC Service Co LLC, we provide all the services you need to keep your AC running in top-notch shape. Call us for repairs, maintenance, or new-system installation.

Air Conditioner Repair in Plano, TX 75025-6300

“My request for service on July 4th was left on voicemail. To my surprise Betty returned my call to acknowledge my request for service. Betty was unable to provide a date at that time and said she would call the next day. Sure enough the next morning Betty called and scheduled service for the following day, Although this was not an emergency I was delighted with the rapid response. Friday, Dwayne arrived on time (I was a little late) and addressed each issue I presented to him. Dwayne efficiently and effectively addressed each issue to my complete satisfaction. I am very satisfied with the Montgomery HVAC company and look forward to a continued excellant working relationship. Thank you Betty and thank you Dwayne”

Air Conditioner Maintenance in Allen, TX 75002

“Montgomery HVAC is the company to call when you need someone you can trust.
We have lived in Allen for nearly 18 years. During that time we have encountered companies which will try to upsell to the extent that they have unplugged a system to make us believe we needed to a new unit.
You will never have that problem with Montgomery, They are honest, prompt, respectful, efficient and very capable. They will provide options and will always stand behind their work. Call Betty, she'll get someone on the job right away.”

“The appointment was scheduled for 2PM. Dwayne arrived at our home 1:55PM. That's about a close to the appointed time as one can get!!! Dwayne attended to his duties commencing with the unit in the attic and than the outdoor unit. We discussed the service that was performed as was documented on the check-list. Dwayne appeared to be very efficient in his work practices and was enjoyable to talk with. I will anticipate continuing our working relationship with Montgomert HVAC in the future and will in-fact attempt to have Dwayne respond to any of our HVAC related needs”

“Every aspect of this company gets an A+ ! Betty (who answers the phone)felt like an instant friend! Steve was right on time and worked diligently to find the problem and tried to resolve it without having to replace the unit. When it was know that we would have to replace the unit, they were so kind and almost "hated" to have to give me the price! We did get another estimate and immediately (!!!) called Betty back! The other company's charge was almost twice as much! I've actually never done a review before…and since reading other's reviews is what made me call Montgomery in the first place, I wanted to add mine! If there were more than 5 stars, I would use them all!”
