"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!

"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."

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

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