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.“

“Our AC broke down during the hottest week of the summer, and we were desperate for help. Oren came to the rescue! He quickly diagnosed the problem and had it fixed within a few hours. He explained everything clearly and made sure the system was running efficiently before he left. Oren is an HVAC pro, and I’m so grateful for his quick response. We’re staying cool again, thanks to him!“

“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!“

“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.“

“Story is much too long - basically, washer stopped working properly.I attempted to have 2 other companies repair, no luck.Reached out to Volta late morning today (Sat). Was able to have technician show up w/in 90 mins (wow!)Dave is a godsend!! Listened to what my issues were, then got right to work. Took less than an hour to assess, diagnose & resolve the multiple issues!!!I have a working washer again! I should have called Volta first! I highly recommend this company.Thank you Dave/Volta ? “

“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!!“

“The technician Zack was punctual, efficient and knowledgeable. He completed the annual maintenance work with ease and was professional throughout.“

“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...“

“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.“

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

“Chris first installed our HVAC system in 2019 and he has been fantastic the whole time we have known him. He was super helpful during installation and has always kept it running great. The one time he was busy and we tried someone else we regretted it. Chris gets my highest recommendation.“

“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.“

“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“

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

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

“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.“

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

“We had still an original almost 50 year old furnace when we moved into our new house. My husband and I took a few years to decide on what kind of new heating/cooling system we wanted to install in our house. I interviewed many different companies. Maybe 6-7. Austin from Comfy Heating was extremely knowledgable about heat pumps. He was very straightforward with his recommendation and didn't give many details, compared to other high rated companies. My husband and I had many questions for him about the efficiency of heat pumps, and Austin got every detail right. At the same time he was offering us a very competitive price. Also the install team was knowledgable. They had one worker less than expected on the day of the install, which resulted in a very long work day for the two workers showing up. They were not able to finish up with everything. After the install we encountered some problems with air leaking out between the heat pump and the ducts than we would have expected. My husband didn't agree with the approach of just putting some tape on the wooden box, and wanted the root of the problem to be fixed, which meant to take the blower out of the heat pump, and insulating the unit with the sheet metal box properly. Comfy heating had to come back a couple of times until the problem was really fixed. And now we have a super efficient heat pump with minimal air leakage. Comfy heating did absolutely a GREAT job in leaving us with an excellent install.“

“Excellent! The best of the best. First used GB Heating and AC many years ago - very professional!“

“Been using Matt to do work for us for nearly 20years. Have openly recommended him to friends and family.This guy is as honest as the day is long, will give you an up front answer about your work, and estimates he sticks to He's done numerous repairs, replaced two water heaters, a dishwasher, toilets, shower mixer valves. He doesn't upsell, but makes recommendations for products that will last. He also will provide parts, or you can purchase your own, and he takes care of disposals (for a dump fee).“

“What great service all around. Found out my air conditioner stopped working and it was 10pm on a Saturday night. They were able to come on a Sunday at 2pm. Diagnosed and repaired in 70 minutes. David was very nice and poor guy had to work in the attic for about 40 minutes. It was 97 outside, so much hotter in the attic. My transformer and fuse to the furnace (which is connected to the AC connections outside). House is only 6 years, so I was praying for a 'repair' bill and not a 'replace' bill. Very thankful it was a repair. I will recommend on my Facebook Tracy Rants and Rave page too. Thanks again David. Feels so nice and cool now and both of the cats are much happier too.“

“I recently had the pleasure of using the services of AC Repair Danville, and it was an exceptional experience. The technician who showed up was Patrick, who was professional, knowledgeable, and incredibly efficient.From the moment Patrick arrived, he was courteous and respectful, making sure that I understood every step of the process. His expertise was evident in how he quickly identified and resolved the issue with my air conditioning unit. Patrick didn't just fix the problem; he also explained the cause of the issue and provided practical preventative measures to avoid future problems.Pat not only possessed excellent technical skills but also had an outstanding customer service approach. He was friendly, patient, and meticulous, which made the whole process smooth and trouble-free. Patrick stood out when good customer service was becoming less common.AC Repair Danville's efficiency, competitive pricing, and quality work have made me a loyal customer. But what sets them apart is their staff, especially Patrick. His dedication, professionalism, and commitment to customer satisfaction were genuinely commendable.I strongly recommend this company if you are in Danville and require air conditioning or heating services. Furthermore, if you are fortunate enough to have Patrick as your technician, you can rest assured that you are in capable and caring hands. In my opinion, five stars are inadequate to rate my experience with Patrick, who has set a new standard for HVAC services in Danville.“

“They installed a generator for my home. The work was very professional I'm very happy with the result. I would recommend them.“

“Wow, I see that my previous review is not recommended by Yelp. My previous review is something like "I want to be in Walter's van when the world ends". I thought that would convey how much I appreciated his help when I needed it..... during the horrendous hot spell of 2022's summer. Walter worked my project into a busy schedule for repair of my 50 year old air conditioner. Working on my deck in intense heat, he quickly diagnosed the issue and went to his van for a part. Fifteen minutes after arriving, he had it fixed. Pricing was, from my view, very reasonable. One and a half seasons since, and it's still running great. I had suffered a major health issue, and really needed help. I can't recommend a business more.“
