"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!"

"They came out within 2 hours of my phone call and fixed quickly the A/C Exterior motor, which had been shutting down. However, two weeks later, the unit began shutting down again. Because I was more familiar with the unit, I was able to act quickly so as not to have the motor burn out. I can not say that the motor beginning to shut down again was due to their negligence or oversight. However, I will need to call either 411 Heating or someone else in order to have someone come out a second time to repair the unit."

"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."

"The company was fast to send a technician over to diagnose the issue and the rate was reasonable, however, they are trying to sell a new furnace too hard instead of trying to fix the old one, the second technician they sent who was supposed to estimate the new unit cost is pretty rude to my tenant, he basically ignored our questions about the repair cost vs. replacement cost, he said to my tenant 'hey I am not talking to you, you are not the owner of this place' simply because he thought the old unit can be fixed. Once he realized that we want to try the repair first before buying, he got up and left without saying a word. He has a very bad attitude and downright rude. I gave the company 4 stars for sending people over quickly but 1 star for their customer service. they need to train their technician some manners. update 2/4/18, after I posted this review, the company called me to get more information about this event and wanting to improve their service, I was very impressed how they trying to make things right and apologize for this unfortunate event. I understand that it could just be this one technician and the company seems very concerned and wanted to do the right thing. I changed my rating for this company because I think they do care about customer service and is making an effort to fix their mistakes."

"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!"

"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 Walnut Creek, 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.
