We bought in a mid-century house whose furnace is located on the roof . It is a common location for…read morethis type of house, but -needless to say- it is not easy to replace that furnace when the need comes. We decided to hire ATLAS for the job: the furnace was old, and the original roof ducting did a lousy job distributing the heat throughout the house. I was always cold even when the heat was "blasting". ATLAS did a thorough and patient analysis of our old system. They decided to double up the ducts to provide more air flow, and they also organized the flow inside the ducts: it worked. Frankly, the final cost was reasonable, considering the benefits I am getting from it. I particularly recommend Nick and Scott who supervised the project: they really looked into the project, then fixed the problem. Plus: the work was clean, and the communication great all along. Happy customer :-)

Top Level: Initial screw-up, great recovery…read more Atlas heating installed our furnace nearly 20 years ago and it has worked well until recently. We started having problems with it, so we had a technician come out to perform preventative maintenance. However, less than a week later, it died completely and I could not revive it. I called Atlas, thinking that I would be a priority for service, assuming they would stand behind their work. Instead I was told that I could not get scheduled for service until 5 days later, and the money I had spent on the maintenance was essentially forfeit, as I would receive no credit towards the repairs. Instead, I went with a different company that diagnosed and repaired the problem two days later. After the rather disappointing interaction with Atlas, the owner called and was mortified at how I was treated. She was extremely apologetic and offered to not only refund the cost of the preventative maintenance, but tried to give me even more money for the poor handling of my case. While I did accept the refund, I did not think it fair to take more money. We parted on good terms and when it comes time to replace my furnace (in the near future), Atlas will definitely be part of the process. I would leave five stars, but have to deduct one for the initial poor handling of my case.

His expertise, professionalism, and efficiency were immediately apparent.

It's rare to find a technician with this level of knowledge and diagnostic skill. If you're looking for someone who can quickly and accurately troubleshoot HVAC issues, I highly recommend Ratmir and the team at Galaxy Heating & Air Conditioning.

We took advantage of the free design services for a heat pump heating system offered by QuitCarbon…read more After completing their home assessment questionnaire they gave us sizing, pricing and rebate information. QC referred us to Harry Clark Heating and Air Conditioning for a complete upgrade to replace our gas furnace. HC owner Don Marshall spent an hour and a half assessing the existing heating system in our 1908 home, answering all our questions and providing a detailed quote for a two zone system the next day. After reviewing the quote with QuitCarbon, we decided the price was competitive and chose not to get other bids. I should mention that I'm a licensed mechanical engineer and have lots of experience working with contractors. Armando Hernandez and his crew completed the install in one week and we were up and running on day 5. The quality of the workmanship was excellent. Armando addressed my many questions and was a pleasure to work with. There was an issue with a defective part in the air handler. The project manager Matt Schwoyer was able to resolve it with their supplier, and the part was replaced the following week. Everyone at Harry Clark was professional and responsive throughout the whole project. We are pleasantly surprised with the improved and consistent comfort level in our home and would recommend HC to anyone considering a heat pump retrofit.

I opened a project on Yelp and went with Harry Clark. Oscar was the tech who came out on the scheduled appointment date. He was very tidy wearing shoe covers and after climbing his ladder to get into my attic, he was able to determine that it wasn't the pilot light that was the issue with my furnace, but it was simply turned off. He turned it on and then went to work installing my smart thermostat. After he got it installed, he showed me how to adjust the settings. Finally he also examined my living room fireplace and showed me where the switch was inside the panel to turn it on. He was clean and efficient and I'm very happy with the service. I called them later and asked to be put on a list for annual furnace maintenance. High recommend Oscar and Harry Clark Heating and Air.

To their credit, the company responded and offered a $50-60 credit, but given three other companies quoted the same repair at $450-$650 all-in, it's hard not to feel overcharged. Decent communication, but the pricing transparency needs serious work.

I received exceptional service from Air Flow Pros during what could have been a very dangerous…read moresituation. On the coldest night of the winter, my carbon monoxide alarm went off. Later that evening, PG&E confirmed that our furnace had failed and was releasing carbon monoxide into our home. The next morning, I began calling HVAC contractors. None of the nine companies I contacted could help for at least a week. Fortunately, a friend from my daughter's school referred me to Jose. He answered on the second ring, immediately understood the issue, and told me his Vice President would be at my house within the hour. Just 30 minutes later, Rudy arrived and quickly confirmed the diagnosis with his equipment. Jose immediately recognized the urgency of the situation. Not only were we without heat in freezing temperatures, but our family was also at risk of further carbon monoxide exposure. By 5:00 p.m. that same day, Air Flow Pros had sourced and delivered a new furnace, assembled a six-person crew, and begun removing the old unit. By 8:00 p.m., the new furnace was professionally installed, the work area was spotless, and our home was once again warm and safe. The service was truly outstanding. Air Flow Pros delivered a high-quality product at a fair price and completed the entire job within eight hours of my initial call. I couldn't be happier and would recommend them without hesitation.

He and his team even convinced me to go in a different direction from what I originally planned. In the end, I'm glad I listened, I'm extremely happy with my new setup. Not only do I now have both heat and AC, but they also helped minimize the visual impact of the mini-splits, which was a big deal for me. The install was great too. Miguel was respectful, answered all my questions, and kept me informed anytime something didn't go exactly as planned. Overall, the team really worked with me to get things right, and I appreciate the effort they put into the project.

We recently had Angel and his team at Velasco's Heating & Air Conditioning install a Bosch 20 SEER…read moreheat pump system with duct upgrades, and the results far exceeded expectations. The system passed all HERS inspections, but what really stood out was the duct leakage test: only ~4% leakage, which means about 96% of the air is being delivered into the home. For context, most homes lose 20-30% of air through leaks, and even many "good" installations only get down to 7-10%. Angel's results are better than code requirements and show true attention to detail. Angel was professional throughout, and his crew -- Julio and Felipe -- worked hard, were polite, and left the work area clean each day. We can already feel the difference in comfort, and knowing the installation was done right gives us peace of mind. If you're looking for an HVAC team that delivers top efficiency, full code compliance, and workmanship above the industry standard, I highly recommend Angel and his team.
