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.

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 Air Synergy, we provide all the services you need to keep your AC running in top-notch shape. Call us at 925-510-2037 for repairs, maintenance, or new-system installation.

Air Conditioner Repair in Rio Vista, CA 94571

“Luis was able to determine what the problem was with the air conditioner, showed me the bad part, explaining what had happened, replaced the part, then checked to make sure everything was working correctly in a very timely manner. He was very courteous and answered all of my questions.”

Air Conditioner Installation in Other, CA 94505

“From the beginning to the end, everything was great!!! I felt very comfortable throughout the entire process. I never felt pressured or like this was a ripoff in any fashion (like the last guy who ghosted me so Air Synergy had to come in a clean up his mess). They were very professional and very time efficient. The crew, Josue, Mario and Shawn were great. Several times they laughed, and I mean that gut-wrenching laugh, while working – it sounded as though they were really having fun – working!
Air Synergy came referred to me by trusted friends and I would not hesitate to refer them to everyone I know and to my clients, as a Realtor.
I would use them again for any of my other properties, because I don’t think I will be needing them for my home, again. Alberto gave me the best kind of warranty! This was just a great experience – I loved it!!!”

Air Conditioner Replacement in Oakley, CA 94561

“I am so very pleased with the service we’ve received from Air Synergy. We used them for a full furnace/AC replacement and the process was wonderful from beginning to end. Alberto was extremely informative during his first visit with us and did not hesitate to return to our house a few days later when we had a couple more questions to ask. We received quotes from four different companies and the pricing from Air Synergy was extremely competitive. The staff that performed the work were all very knowledgeable and respectful during the entire process. We also had Air Synergy move our A/C unit from the back of our house to the side of our house and it looks so much better not seeing the unit as soon as we walk out of the back door. The pricing to do this additional work was also very reasonable. We are extremely happy with Air Synergy and would recommend them to anyone, especially those looking to support local businesses!”

Air Conditioner Installation in Walnut Creek, CA 94598

“From the first engagement with Air Synergy to the final installation of my new home air conditioning system, the service level was professional, informative and super responsive. I was uncertain about what improvement pathway to select and I was presented with several informative alternatives that incorporated the overall improvement to be gained in overall home environment quality, power efficiency compared to the required investment. On the day of the installation, the crew arrived on scheduled and did not leave for the day until the work was completed and the air system fully functioning. I highly recommend Air Synergy.”

Alberto quickly assessed the immediate problem and fixed it. He provided a concise explanation of what was wrong, how to fix it for the short term and what my options were, cost upfront and quoted me on the spot for replacement of my air conditioner and heater if needed.
