"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!"

"We actually called this company out on the previous Sunday.  We were getting small gas explosions whenever the furnace turned on.  We first called out PG&E, and their field-service person red-tagged the furnace and said that we would have to call out a professional service to deal with the repairs.
The company owner came out promptly on Sunday and inspected our furnace, and gave us an estimate of about $500 to repair it; he clearly and thoroughly described what the issues were and what needed to be replaced.  However, the furnace was over 40 years old, and he suggested that I consider replacing rather than dumping that much into interim repairs.  His comments seemed reasonable to me, so I agreed with him and asked for an estimate for the work, which was $2600 for everything involved.  Once I heard that, I was *very* pleased, because when we previously got a quote to replace it, the other company (no longer recall who) had wanted over $4000!!!
Anyway, his workers came out yesterday, arriving a few minutes before the 0800 appointment, got immediately to work, and had the entire job done in 5 hours.  They did immaculate work, didn't mind me watching over their shoulders as they worked, and I am quite pleased with all of their work.
We also love the new furnace!!!  We never realized before, how weak the old blower was; the house heats up *amazingly* fast now, and it has an electronic ignition, so we don't need to worry about pilot lights any more.  The reason I'm mentioning the equipment is to communicate that they clearly choose good-quality equipment to install.
Highly recommended!

"Was very responsive throughout the process. Called us back shortly after sending request for quote via Home Advisor. Came within the two hour window offered the very next day and completed the job without delay. Technician repaired our Central AC during a historically hot stretch of weather and did not oversell us on having to upgrade or replace our unit which was refreshing."

"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."

"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."

"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 San Ramon, 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.
