This company gave me a very fair price, and it is hard to find a company these days with both a good attitude and reasonable pricing. Jesus is a very good worker, and I really appreciate his effort. I will definitely recommend this company to my friends and family, and I will call them again for any future air-conditioning problems.

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.

Was quoted…read more$45 for the service call upfront, but ended up being charged $840 total -- $640 for a part that runs $200-$250 at wholesale, plus $200+ labor for a 30-minute job. The tech also asked for cash, which felt odd. When I pushed back on the diagnostic credit, the numbers didn't add up. 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.

They sent a young man by the name of Jonathan Enamorado who was very polite and even put on shoe covers prior to entering my condo. He looked at what needed to be done and I told him since I was recovering from cancer, my grip is weak and all I needed was some help in unscrewing the connection between the tank and the water source. He gladly helped me remove the connections. I assured him that I can do the rest since I have the new filler and bidet, and that I have done this project before, this wonderful young man didn't even charge me a penny. Employees like Jonathan is what makes a customer become a repeat customer. Thanks Jazz for the excellent care that Jonathan provided! I'll definitely call you again if I needed any plumbing, electrical or HVAC issues!

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.

The new refrigerant line install looks very clean and inconspicuous against the side of the house (I couldn't even tell it was there without Jose sending me photos later on of where it was placed). The AC works like new, and the quote was very reasonable for the amount of work that was involved. Will definitely contact Air Flow Pros in the future for other jobs. Thanks Jose!

It is great to have a heating system that works and an air conditioner for the first time. The staff at Comfy was very patient getting the permit and sending us all the necessary paperwork. We highly recommend Comfy.

I wish more companies were like this.
