"Prompt, courteous, hard working! Called for service and they came the same day and gave me an estimate for repair and an estimate for a new furnace! I decided on a new furnace as mine was 18 years old! They came the next morning and were done within 2 hours! The thing I liked most was they didnâ t pressure me at all but waited patiently for my decision!"

"Thought all these 5 star reviews were "suspect" until I experienced them for myself. WOW. Just WOW. End to end the experience was amazing. I received a text message detailing my appt, they even sent over their contact details for me to add to my phone for future. Sent a photo and details of the service rep and follow up to make sure everything went as planned. Very through detailed walk through of the problem and my heating / air system. THIS is how all companies should run their business. Our current system was 24 years old and we wanted to replace proactively. The crew was absolutely amazing - very efficient, knowledgeable and confident. Installing a heating / air system is complicated and requires skill. I don't need to worry if my system will work, or how to get service. I now have a team I can call and know everything will be cared for."

"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

FAQs for central a/c service or repair projects in Brentwood, 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.
