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 DS Heating & Air, we provide all the services you need to keep your AC running in top-notch shape. Call us at 661.231.8118 for repairs, maintenance, or new-system installation.

Gabriel and Adrian well let’s just say I HIGHLY recommend this company because of my impression of these two professional techs

“Gabriel and Adrian well let’s just say I HIGHLY recommend this company because of my impression of these two professional techs, We had to look out of the area because everybody was booked up here so we searched in Lancaster and we are so glad we did! First thank you to the young lady who answered the phone and was caring enough to get us in the same day. Second, when Gabriel and Adrian came they were professional from start to finish. I just can’t say enough about these techs, they cared, even offered to talk to my landlord about what was going on with the AC! Plus they took the time to explain everything to us. I was very impressed with Gabriel’s knowledge of the entire system. Adrian was also very knowledgeable, just an overall great attitude and experience. THANK YOU to both of you for your outstanding customer service. It’s employees like you that show me old fashioned simple excellent customer service is still here!!!already referred you guys on our local FB page👍🏼👍🏼👍🏼”

This is an all solutions company that really does care for their customers and I highly recommend them

“I think this company is a little pricey. After meeting with Cameron and working out the details I find that you get what you pay for. The team, Cameron, Alex, Juan, Angel, Louis, Javier, and Dylon performed the work in a professional manner. All were polite, timely and seemed like an engine as each one completed their tasks. After the installation they cleaned everything and vacuumed to make sure there was no mess left behind. Further, I was lost at programming the new thermostat and they sent out a tech to program it for me. Again, This is an all solutions company that really does care for their customers and I highly recommend them.
Thank you Cameron and crew!”
