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 :-)

When we had more questions, Galaxy sent out another gentleman to go over additional questions and we settled on the same, trane/American standard system . Within a week the full system was scheduled for install. The young men who installed the system were very respectful of the property very respectful of my father since his house is immaculate. You would've never known they were even there they cleaned up so well. They completed all the work in one day, which was shocking they went above and beyond and replaced a water nozzle that had been leaking under his house for who knows how long. We are forever grateful lifetime customers. We hope that you will be too. Thank you, Galaxy for your professionalism, hard work, above and beyond and work ethic.

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.

Hi, I just had a Google Thermostat E installed by Anson Wong of Olympic Heating and Air (he is the only guy). What might have been an easy task took much longer because there was some kind of metal plate behind the plaster that was packed in around the older set-up in my 1927 home. He had to remove all of the plaster and find a way to screw new set-up in. Suffice to say it wasn't typical HVAC work and he did it willingly. If there are any probs he would return and he lives in the Dimond/Laurel area! read more

No BS, just an honest helpful team. Long Story: I got home late on a Tuesday from a business trip to have my wife tell me our heater isn't working. I spend an hour or two messing with it with no luck. I pull out the one space heater we have and put it in my 10 month old daughters room. Christmas Day is Saturday and it's been rainy and colder then usual all week. I start calling around early Wednesday morning. I call anyone that seems like they have a website and a storefront if someone sort. Most tell me they are booked out till January. Earliest appointment I can get is Dec 27th. One guy warns me to be careful because the "reputable" companies are all crazy busy that people are getting scammed with high prices and shoddy work. Now I'm starting to feel a bit more desperate so I call anyone that seems to have decent reviews. I come across SF Bay Air on yelp. Can't find a google listing, a website or an address for them but they seem to be very close. I call, no one answers and I leave a voicemail. Nabil calls back an hour or two later and says it's a crazy day but he will find a way to get out to take a look by the end of the day.Can't promise a time or even a rough window but they will be there. I ask him about cost and he tells me it's $125 to come out and diagnose the issue. Late that afternoon Ali from his team calls me to say he's on his way. He shows up and within an hour is able to find that a motor is acting up. He tells me he can get the part in the morning and then come install it for $800 all in. He also said we would only charge me The $125 if I wanted to order the part and install the part myself. I tell him to go ahead. Again no promises on when they would arrive but he ends up back at 10AM the next day gets the part swapped and everything working. Makes sure to have me test turning the thermostat on and off to make sure all is good. Ali even mentioned he saw the diapers form my daughter in the basement so he knew he needed to get this fixed ASAP. Nice to know someone cares these days. Would highly recommend to anyone.
