5.0 Katherine B. Aurora, CO

Easily the best company we've ever hired for anything. From the first time I called (just before 5pm), every single employee I encountered provided top notch customer service. Dixie & Faith were both very personable and helpful on the phone. I also ended up speaking with Jim, the owner, who was amazing. He made himself available to assist us after hours and was very knowledgeable, patient & reliable. He genuinely cared about trying to get our furnace fixed as quickly as possible. (And that was all before anyone had even walked in my front door.) Then Nixon, the Operations Manager, arrived promptly to assess my furnace. He was incredibly knowledgeable, very respectful, communicative, honest & thorough. He diagnosed the problem, explained the issue to us & provided an honest and reasonable quote. Upon approval, he quickly got the part & repaired it. At no point did Nixon seem even a little bothered by the fact that it was 6pm on a Friday. He patiently answered a couple questions and didn't try to oversell us anything. I am beyond satisfied with every single interaction we had with JC Mechanical. I cannot recommend them enough. I would give them 10 stars for the best customer service we've ever encountered. The incredibly knowledgeable staff & affordable pricing were simply the icing on top. They've earned a customer for life. And I will sing their praises anytime I ever hear someone looking for an HVAC contractor. Top notch across the board! Stop searching & hire them immediately.

JCMechanical's professional that came to tune up my AC was very friendly was very diligent in his work. I was pleased and if I need any work done on my AC I would definitely call them again.

5.0 James J. Aurora, CO

On time, professional attitudes from both the workers than showed up. Followed up with additional requests after install. Couldn't be happier with my new furnace and the service I received. Highly recommended

5.0 Casey O. Denver, CO

JC Mechanical is probably the best HVAC contractor that I have worked with. I had hired a new 24/7 company to come look at my furnace that wasn't igniting. They were there for three hours and it didn't sound like they knew what they were talking about. After that disaster I hired JC Mechanical for a second opinion. They showed up the next morning and properly fixed the issue (throw safety breakers) in five minutes. I will absolutely be using them again.

5.0 Russell P. Denver, CO

We had a 22 year old furnace and AC that JC Mechanical replaced. I got 3 estimates, and for similar equipment, theirs was the best price, and they even threw in a couple of repairs and parts for free as part of the work. They finished most of the work in one day, wrapping up the next day. The old system was not installed properly, so the retrofit to the new system took a bit longer than expected. Jim Jr, Mike, and Jim Sr were very professional in their work, making sure they got the installation just right. I would highly recommend this family-owned business.

5.0 Kerry M. Aurora, CO

Reliable, courteous, proud of their work, stand behind their work, did a perfect job installing my furnace and I will use them again
