"In the middle of a heat wave, a/c went out...emailed 7 or 8 businesses and 5 were 2 to 3 weeks out. This company came out in 1 day and fixed the problem in 1 hour. Prompt, professional, no bullying or scare tactics. i would recommend this company without hesitation. My tech was Johnathon Martinez and at no time did i feel he was going to milk the job or B.S. me. You can believe the ratings for this business."

"

They have been great. They helped me out a lot. They came out pretty quickly and helped me decide what I needed to do. They got the work scheduled and were able to come out on short notice. They took care of a couple of things right away. Ultimately we were very happy with the equipment they helped us select so, everything -- service, equipment, follow up, scheduling -- and the people they sent out here were terrific too.

"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

"Great team! Mark, Sergii and Pavel replaced my furnace and installed an AC. It was a real pleasure to work with them. Mark listened carefully and provided several options for me to choose from. He was also flexible on scheduling the work to match my family needs. Sergii and Pavel performed the installation exactly as planned, kept the house clean, and payed a lot of attention to the aesthetics of the visible parts of the system. They explained to me where they'd run the lines, what were the options and why they preferred one over the other. I'm very happy with the choice of brand and model and with the installation. The team really cares about their customers. Thank you!"

"Ricardo was timely and professional, quickly diagnosed the problem and hone in on the best solution. He is down to earth and know what he's talking about. He didn't push for irrelevant repairs or upsell me on more expensive solutions and just focused on fixing the root problem. Would love to work with him again."

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