Long overdue review for James and his Team!…read more I had hired them a few years back based on their reputation and excellent Yelp reviews for a furnace installation & ducting in my own home and they did an awesome job. Great communication, workmanship, and efficiency. They were first to come to mind again when I recently needed another old furnace replaced in a commercial tenant's space. Time was of the essence and James accommodated us into his busy winter schedule within two days. Since the furnace was very old and ducting was from another era, James communicated right away all of the potential issues. His team even stayed late to complete the install in the same visit so the tenant could have warm air right away. Any unusual or other issues that arose during the install, James communicated and had resolved as soon as possible to ensure client satisfaction. I am very picky when it comes to professional building techs, but would give 10 stars to Ocean Air if I could. My only disappointment is that they do not have a plumbing, electrical, or general building maintenance arm of their business!

Oren came for an in-person estimate and very promptly sent back a quote. Of the 3 quotes I…read moreobtained, it was about 50% higher than the quote I selected, but the same as the other one. I think Oren would have done a good job, but I made my decision largely based on price. I think the quote was fair, but the difference perhaps was the position of the condenser and the route (i.e., more vs. less work) as well as uncertainties related to permitting (i.e., whether unforeseen additional work would be needed). I'm glad I got a quote from him and appreciate his time.

The pricing also seemed extremely reasonable. We ended up doing insulation in our ceilings, such a seamless experience and they supported with the rebate process, had finances not been a limitation we would've done walls. Highly recommend, in fact writing this review has inspired me to loop back with them about their suggestion that our furnace is waaaaay overdue.

Angel and his team did a whole home mini split system for me…read more It is comprised of a 4 zone unit for the bedrooms and then a large single zone unit on the other side of the house for the kitchen great room. All of the bedroom units are flush mounted in the ceiling and look great. Angel was very professional and prompt during the quoting process. He managed procurement of the Mitsubishi system and then was very accommodating of our moving schedule based on other less reliable trades at the house. He was absolutely the most reliable and best communicating tradesperson that I have worked during my recent remodels. His team always showed up on time and did great quality work. I would highly recommend Velasco to anyone looking for an HVAC contractor. Great quality professional work at a very reasonable rate.

I originally was going to replace my outdoor ac unit…read more After meeting with them and reviewing my options, I opted to replace my existing AC and gas furnace with a new full electric heat pump system as gas furnaces are getting phased out in 2030 in California. The estimate appointment, equipment procurement , and install was a breeze with a quick turnaround. Angel (the owner) was very helpful, answered every single question I had, and work through the estimate with me to make sure it worked with my budget. Once the equipment was at their shop, it only took 1 day for them to get started and completed the job in only two days, on time and on budget! I truly recommend their services

OMG, Gerald is SO knowledgeable about residential boilers and heat pumps! He is super familiar with…read moreour old Munchkin boiler, that he kept a graveyard of them as a source of parts for the now-discontinued product. He was very responsive to our no-heat, no-hot-water situation and made room in his schedule to get it fixed right away. He knew why the boiler had failed and what was needed to prevent it from failing again. He charged less for the whole job than another contractor was going to charge just for the parts. As well we discussed heat pumps, and he was fully aware of what would need to be changed with our system to use a heat pump instead of a gas boiler. The guy knows his stuff, is responsible, and is a straight shooter. He saved us from out boiler outage quickly, and we have found our guy to install a heat pump. I could not recommend him more.

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.

My furnace was out for two and half years, so I thought it would be a good idea to get it fixed…read more In addition, I bought a smart thermostat and wanted to get it installed. 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.

Communication with him was super easy over phone/text, and after briefly describing the problem to him and sending some photos he was able to diagnose our problem and the part needed to repair our boiler almost immediately. Customer service has been great. He gave us a thorough overview of our system and recommended maintenance that would likely be needed for the remainder of the boiler's life. He even followed up with us to ensure that our hot water continued to work after his repairs before billing us. He is definitely your best bet for quick, efficient, and expert service for heating/cooling system issues in the East Bay!
