HVAC reviews in Concord, California

I feel 100% confident anytime I use Chris and his team for my HVAC needs. From having a new heating unit installed, to moving my AC to the attic and a full service done, work has been thorough and professionally completed. I would recommend Devil Mountain Mechanical to anyone.

Chris and his team did an excellent job replacing our HVAC system. Chris runs a tight ship, he’s on time, every time. We had a special circumstance and needed him to work closely with two other contractors to do the job, and he worked very well with everyone to get the job done and done well. He and his team are also very kind and a pleasure to work with. I’m very happy we went with Devil Mountain!

Great Hvac distribution company. Easy to work with and fast to get you what you need.

Nick is very knowledgeable & helpful anytime i needs parts and supplies - would recommend US Air to all my HVAC contractor friends

Amazing services, thanks a lot for helping me each project, will always use this guys for any other HVAC projects!

Service was great, had the parts I required in his truck. The service cost seemed high to me; $350 over what the parts cost online for an hour's work. But hey, it got done then and there.

Great service and friendly technicians.

Jose did a great job!

I HIGHLY RECOMMEND THIS PLACE AIR CONDITIONER PUT IN LAST YEAR.EXELLANT SERVICE.THEY ALSO CAME OUT TODAY AND REWIRED AND PUT IN ANOTHER BOX.MY AC WASNT WORKING.NO CHARGE THEY WERE HERE FOR ALMOST 3 HOURS.THEY R VERY PROFFESSIONAL,AND VERY SMART.ALWAYS 2 PEOPLE COME OUT AND EVEN THE BOSS TO CHECK THINGS. NO CHARGE FOR ANYTHING.VERY HONEST PEOPLE.

I got the top of the line unit for the best price, and the guys are fast! I ate lunch and they were done. Thanks guys you saved me.

Great personal service. As a real estate professional I always recommend this company to all my company because they are so reliable and always available to take care of any emergency.

the only company that charges $65 to look at the furnace. The estimate was double of any other company. Very dishonest tired to sell me a furnace that did not need replacing.

installed $ 8.00 capacitor to the old A/C Condensor and charged $375/- in maximum 10 minutes. I consider it a Highway Robbery. Anyhow, the a/c started cooling. The trick is $65/- Service Charge to get you hooked to come.

Villi was my tech today ; arrived right on time, polite, careful, sincere, and he explained everything and answered all my questions
.Very good experience this time in a long time
Very honest and told whatever I needed to know
Thank you Villi for your help today!!!

Very fast response to come and fix the problem with our ac unit. Also very knowledgeable and professional service; definitely will keep you in mind for future service. Thank you!

REALLY OVER PRICE!!!! This guy MARTIN S..... a technician from this company charged us $1000,00 dollars for the replacement of a single icm282a furnace control unit of our heater.. which is only $ 136,00 dollars in the store... I strongly suggest be careful with this guys.. they will eat you with the crazy price....

They did a great 👍 job especially since we are having a major heat 🥵 wave.I would highly recommend them for all your heating and air conditioning needs.

I called for my heating furnace, guy replace the electric ignitor, which took about 15 minutes. He then charged me $228.00 for the ignitor (afterwards I researched and it was a $20.00 part) and $174 labor. If I wasn't watching him he would have charge me even more and said it was the main board... which he tried to do, but I told him I didn't think that was it and to check the ignitor. I'm no idiot thankfully... if I was less informed I am sure he would have price gouged me for even more. DO NOT USE THESE GUYS for your repair work... go to the next one. They were not very customer oriented... no wonder they were available same day.
