"After having my a/c unit looked at my service guy said it would need some work but the unit was 18 years old. He told me they had some good deals going so I took at look. He sold me a Lennox Air Flow unit and an updated larger return to get my system up to speed. They installed the unit and return on the following Wed and when I got home that evening and took at look at it to my surprise it was a different unit than the one I purchased, a Rheem not a Lennox. I called the company to see what was going on and was told the install manager would return my call, he never did. I called again and finally got  the install manager and he told me the unit they sold me was too big for the area I had so they upgraded me to this unit. He said he would email me the dimensions and  the paperwork for the new unit, he never did. At this point I am thinking I just got screwed and they are hiding something. I called the company again and the reception girl told me someone would call me back, they never did. I gave it one last try before calling my lawyer and asked for the company manager, I was told he wasn't in yet and that he would call me back. This time I did get a call and he really couldn't tell me why but said the unit they put in was a better unit and he would find out what happened. He emailed me back and explained the situation and I was satisfied with his explanation, but it was not what the install manager had told me. All in all the service people they have on the a/c side are great but the office people are a little sketchy. The unit works great but I really had to jump through a lot of hoops to get satisfaction and at the price I paid I should not have had to. A simple phone call from them telling me the problem would have averted any concerns, but like the several calls I made to them, I never got a call. I probably wouldn't use them again but I am kind of tied to them for taking care of my new unit under the warranty."

"We received the phone number of this company from a friend that hired them and he was able to reduce his utilities bills by doing an efficiency audit that includes covering all the openings at the house (windows, HVAC, Doors etc.?.) and then with a machine, running the test and to see from where the house is losing most of the energy and to perform a repair that will prevent that in the future. Ezra and his team of workers came to perform the test and to see what need to be repaired or improved. The audit took close to 5 hours and then the machine that they used worked for additional 2 plus hours. After that was completed, we saw clearly that the problem was the windows and the HVAC. Ezra recommended us to perform a repair to both of them and then to run the test again. After the workers of them finished the repair, Ezra came once again and did the test. He was pleased with the results and so as we. During all the work, we saw how it was before and how it was after. We do recommend this company for that type of work! They are professional and honest people to hire and they carry all the relevant licenses as well."

FAQs for central a/c service or repair projects in Hamilton-city, CA

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
