McCormick Heating, Cooling & Electrical

Justin replaced my furnace today - we have worked with a lot of contractors, but Justin was by far the most courteous and professional one yet. He took care to use drop cloths, was polite, friendly and even early. What impressed me the most was that he thought of the end user - he moved our switch to where it was more accessible and built a custom door for our air filters with instructions to help me! Way to go
McCormick - thank you for taking such good care of us today!

Our air conditioner totally went out and we had to buy a new one. Angelo was the lead technician and was here literally ALL day. He started about 0800 and didn't leave until 1630. Very detailed and exact about his work. Would highly recommend McCormick to others based on Angelo's work.

Wow! Jasen and Justin did fantastic work. They went above and beyond and even cleaned our routing of our drain pipes and such which they didn’t even have to do! Great work and thanks for being so cool!

We will definitely be using these talented guys again!

McCormick installed a new HVAC system in my home in August 2022. When the Greater Denver area experienced frigid temperatures in late December and January, it took forever for my home to warm up. McCormick agreed that something was "off" and needed fixing. Today, the solution arrived in the form of Josiah, a young technician who is smart, professional and personable. With some guidance from the manufacturer, he located the problem in the furnace, adjusted some switches and bingo! The problem was fixed in the blink of an eye! And the explanation made complete sense to me. This is a company that stands behind its products...many thanks to Josiah, Jasen and Brittany for resolving the situation.

Everyone was nice, helpful and kind.

However, we had a furnace install with McCormick this past December and everything seemed to have worked perfectly fine. We are installing a new AC (with a different contractor) and they were quick to highlight some in incorrect aspects of the furnace installation. I’m sure this is a great company, but bummed that our AC installer has to make changes to the furnace that was installed.

Guys were great. Angelo and Justin. They deserve a tip. Showed up on time. Worked hard all day. Installed AC in a mountain home with some complexity due to the topography. Fantastic work!

Jason and Justin came to install our furnace and ac and they were amazing! They were kind, hardworking, and respectful the whole time they were here. We will definitely be recommending McCormick to anyone we can because of them! Thank you guys so much!

I've used this company twice now through my home warranty both for an HVAC issue and for an electrical issue. Both of the technicians were really polite and professional and seemed to do a really good job. I just had Jake over to fix an electrical problem and he was really friendly and figured things out quickly. This company also seems to be very timely in both their response from the dispatcher and prompt on when they show will up. It's much appreciated! I would happily go with this company again.

Justin was incredible! Professional, extremely polite, efficient, and walked us through all the install updates when he was finished. He also cleaned up and make sure the space was the same when he left it. Could not recommend this company and Justin more!

Justin was amazing professional and very caring about getting the new AC installed. If ever I need new furnace I will be asking for Justin!
Tayler was very knowledgeable and helpful in the early stages of AC purchase and coordination of install.
