5.0 Dan N. Littleton, CO

Great response and service. We replaced a furnace at our home.

5.0 Lorraine P. Denver, CO

Professional, quick and efficient, no mishaps during the job- and friendly, too! A very pleasant experience!

0.50 Angela C. Denver, CO

Bought a $17000 Rheem air conditioning and heater on October 24th. Install was a mess, techs were here until 9pm. Front office had no idea what was going on. It took them a total of 3 days to install the HVAC unit. Failed the inspection, absolutely ridiculous. Today, Nov 25th, at 12:30am, the furnace stopped working its 11 degrees outside. Nixon the service manager came out to look at the furnace, determined the control board is not working. Nixon called the owner Jimmy who said in order to get a new computer board we had to pay for the supply house to open up and they may not even have the part. Jimmy couldnâ t tell us how much it would costs to do this or if the needed pert would be available. Of course we were not happy about us needing to pay for this on a brand new furnace and expressed our frustration to the owner. We asked if they could provide heaters with it being 11 degrees we were worried about the pipes freezing. They refused to bring out heaters and said we would need to wait until the morning. The owner became extremely combative and told us â we were lucky they even came outâ and â he would be sitting back laughing at whatever happens with our situationâ . His own employee, Nixon, said he could defend the owners comments or acts. Strongly recommend that you avoid this company.

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.

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
