"It was a scam. The price was too good to be true. My AC was not working and all I needed was someone to take a look and see what needs to be fixed. The cost quoted was $59. I even scheduled the appt. But once I called them for something, they said the appt process through Angie's list does not work and the $59 is only for changing the filter or something silly like that and I had to upgrade to the $89. But for the $89, the guy did spend time with me explaining what is wrong and if its worth fixing or not. So, why advertise as $59 with bunch of details that you won't even perform?"

"I highly recommend Aire Serv of Campbell & Saratoga to anyone in need of HVAC services. Alton helped me find the right system that works for our home within my budget. Alton was knowledgeable and truly explained the different options & HVAC available that would fit for our home. Alton answered all my questions with patience and expertise. The installation crew (Rene & Julio) were on time and explained the complete removal our old system and installation of the new HVAC. They treated my home with respect, cleaned up thoroughly after the job. I like their attention to detail and commitment to doing the job right the first time. Thank you for making our home energy efficient. I'm happy with the results."

"Highly recommend Alanis Air! I own a commercial property and when one of my tenants called about an ongoing issue, John came out and brought his team to quickly diagnose. Explained the pros and cons of repairing compared to replacing. Was genuine and gave me a price I could not pass up. Coordinated the project with the tenant and replaced the whole system smoothly with zero business interruptions. Tenants are more than satisfied with the new system and extended their lease. Excellent service, gentlemen. Thank you Alanis Air!"

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