Heating & Air Conditioning / HVAC near Alamo

“Elliott Air Systems did a phenomenal job with the installation of a new Carrier heat pump system in our home. They carefully removed the 80 year old gas furnace from the crawl space and patched all holes. They installed the air handler in the attic and carefully cut in all new vents in the ceiling. Duct runs in the tight attic space are installed with the highest level of care and craftsmanship. They were extremely diligent about managing dust and mess; the only sign that they had been in the house were the new vents in the ceiling. As an architect, I have the opportunity to work with a lot of different contractors. Based on the great experience I had working with them in my home, I highly recommend Elliot Air Systems to all of my clients. Great value, phenomenal work; EAS earned my highest recommendation.“

“We went to fire up the furnace and no heat. If you are reading this review you are no doubt inundated with the amount of people that can replace your furnace or air conditioner. I asked our plumber Jason Cooper who does all our work and is very trust worthy who would he recommend and his response was immediate - Wes Gardner. Wes came on site and the control board was dead and it was a $1000 repair and Wes recommended we replace the entire unit because it was 17 years old and get this the air conditioner was the original from when the house was built in 1977. There was also a multitude of other issues that Wes found and repaired like the air return being disconnect and drawing air from outdoors. Wes was great to deal with, straight forward and matter of fact about what we needed and no over selling on all the gizmo's you can get these days. We felt in very safe hands and Wes had us back up and running in less than a week with a brand-new furnace and air cond even with all these "supply chain issues". When I sent a text to Wes thanking him for getting us operational before Thanks Giving he responded that he takes pride in his workmanship and it's clear that he does and he has years of experience to go with it. I definitely recommend Wes and Gardner Heating and Air Conditioning.“

“The blower motor broke on my Carrier Infinity furnace and they were able to get the motor the next day in Concord and changed the unit for me in Oakland. It was also covered under warranty even though they did not do the initial installation. When it comes time to change the unit I would use them.“

“10/10 for quality and service. Oren is a great guy and has a team of experienced and loyal experts.“

“Top-notch roofing service! They reinforced my roof and ensured a flawless finish. Great customer service, excellent workmanship, and competitive pricing. Will definitely use them again!“

“Heater stopped working. James came out shortly after (same day), replaced our heater's gas valve, and got the unit back in working order within a couple hours. Will use them again for HVAC or other appliance needs.“

“Andrew with Adrium is a true professional. I initially contacted him via Thumbtack along with 2 other business late at night to get the process going. He replied early the next day and I was fortunate in that he could come by to diagnose the problem with my broken GE double oven that same day. He checked the error code and did some testing and went back to his office to review the necessary parts he would order. He gave me a game plan of ordering some extra parts in case there were multiple problems and said he would only use the necessary parts and charge labor based on what was used. He is prompt, professional and clear about what he'll be doing. I will definitely use Adrium again if I have problems with other appliances in my home.“

“Steve was super helpful and was very clear in the issues with our dryer. He outlined our options for us which was greatly appreciated.
Highly recommended.“

“1sr class operation. They installed two units in my apartment in the Waterford at Rossmoor and came back as many time as needed to make adjustments to make them work perfectly. I called them to come a year later and change the filters and they scheduled an appointment right away. Their technicians are all superb, very well trained and a pleasure to work with. Highly recommend these folks.“

“Eric and Avery came out and showed me what Professionals they are. Very courteous gentlemen. I also liked how Eric was teaching Avery every step of the way!??“

“Contacted these folks and they recommended The Solar Pros. Great company that replaced two bad inverters for a great price.“

“I cannot say enough positive things about my experience with Andy and his HVAC installation service. From start to finish, he was an absolute pleasure to work with. Andy's expertise in replacing my HVAC system from gas to electric was truly impressive. He walked me through every step of the process, ensuring I understood everything that was happening. His pricing was incredibly fair and affordable, which was a huge relief. Beyond the installation, Andy went above and beyond. He conducted a thorough check of my home to ensure everything was working optimally and even offered to continuously monitor the HVAC capabilities to guarantee the best service. Andy is not only a skilled technician but also a genuinely friendly and easy-going guy. I highly recommend his services to anyone in need of HVAC work!“

“Our home remodeling was perfect very reliable company. We love them. We felt really confortable with our home remodeling process. The quality of work was perfect ? We highly recommend“

“Great installation - very good people and a good job. The installation completed late in the night so it might be a long day.“

“Flawless excellent service. We had two instant hot water heater units fully serviced (scale and flush). The technician Victor was extremely knowledgeable and professional. Big Air was running a special so the cost was very reasonable for what is a long job. We liked the technician so much and were so impressed that we will definitely be returning customers.“

“Contra Costa Climate Control did a great job repairing our AC. Another company quoted us twice as much and they just seemed dishonest somehow. That's why we asked a friend who they use, and heard about this company. Thanks for being honest, reliable, and straightforward.“

“Nate is the man — an absolute master of his craft who exudes professionalism and honesty. Really appreciated his patience and thoughtful responses to my questions and concerns. The whole experience was a “breeze” — I can’t recommend Nate and Clayton Brothers Heating and Air enough.“

“Great Service! On time, professional, and thorough. Humbert & Rolando are perfect representatives for your corporation.“

“I cannot say enough good things about Qual-Tech AC & Heating and their technician, Christian. After being without AC for two months, I had already gone through four different AC companies, none of which could figure out the problem. To make matters worse, I kept being told my unit was an Inverter system that they didn’t know how to work on.

Christian showed up and immediately recognized what all the other companies had missed — my system is not an Inverter AC, but a regular system with a circuit board that allows for variable speed startup. That detail had confused every other technician, but not Christian. While I waited for a truly competent company to arrive, my second AC went out as well. Christian was able to repair both units quickly and efficiently.

For context, one of the first companies I called treated my system like a guessing game — swapping out parts on my 2-year-old unit and even over-pressurizing the system, which caused it to fail after they left. Christian found and corrected this issue right away.

He was professional, courteous, and efficient throughout the entire process. After months of frustration, I finally have both AC units working perfectly again, thanks to Christian and Qual-Tech.

Huge thanks to Christian and the entire Qual-Tech team — I highly recommend them to anyone who needs reliable, knowledgeable, and honest AC service.“

“Chris came through for me BIG TIME! It was hot out as you know what out, I was due to have a big gathering in a couple days and the AC takes a crap!! Chris was prompt, honest, communicative, and very fair. He went above and beyond and you get more for your money. If you have a problem with your HVAC call Chris!! HIGHLY RECOMMEND! Oh and I would disregard any negative review as those are probably people who will complain just to complain. IYKYK! Chris is a solid man and great asset to our community in Groveland and the East Bay Area!!“

“Had a great experience! Our AC stopped working in the middle of a heatwave and they were able to come out quickly because of a cancellation and repair our unit for a very reasonable price. So grateful they were able to get it up and running so fast (you miss AC when it is 106!) Thank you!“

“Ron was great! He quickly identified the issue with my furnace, explained my options and proceeded with the repair. I’m so glad I called Sears for this service!“

“There is no one better than Don. Simply put, he's the only one in the business I trust. He's not going to B.S. you into spending money on something you don't need. I had two different AC companies this past summer tell me I needed a new furnace and AC system because I had leak in my system. Cost would be over $20K. Don came over and found a small loose gasket which was leaking gas, which somehow the other two companies missed after being here four times , and possibly even intentionally caused (I was also charged over $1K to refill the puron gas multiple times). Don had a gas detector that didn't pick up any other leak. Net net, Don saved me at least $20K which I'll be forever grateful for!!“

“They brought my old AC back to life! Fast and reliable service. A lifesaver during this heatwave...“

“Jose and Keven from this company just checked my Carrier heater unit. They both were very nice and knowledgeable, honest and patient. They helped us greatly and I sincerely appreciate them both. I would call them again for any problem with my Ac and Heater unit. The only thing was that Keven was scared of my mini Golden Doodle dog?
So if you have dog, put a leash on your dog ? and keep the dog away from Keven.“

“Mike has done numerous projects for us over the years. He is honest, capable, and reliable. I'm always happy to recommend him.“

“James did a great job updating and rerouting my dryer duct. He responded very promptly, came on time, was friendly and polite and there were no hidden or added costs.“
