"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"Due to the extremely old furnace and the damaged burners no work or repair were done.Parts not available. They also were alarmed by the old asbestos vents. I will consider installing a new system and not use gas anymore. They were both polite and professional and frank in warning against attempting any repair of the vintage (fities??) unit. Glad it lasted this long without any serious damage to our home. Thank you."

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"Peter did a great job installing two new furnaces at our house.  Install took a little longer than expected due to venting issues that were beyond his control.  Overall - he was in constant communication throughout the job and his crew was very professional.

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