Can't say enough good things about my experience with these folks. Their office was prompt and communicative. Cruz, who came out to actually perform the diagnosis and repair, was amazing. He was personable and efficient, diagnosing our issue within 10 minutes. Once the part came in, he installed it within 20 minutes, and we were back up and running. All the while, Cruz understood that we are a particularly "COVID-cautious" household, taking all reasonable steps to make us feel comfortable. Definitely my new go-to company for all things heat/AC.

As a first time home buyer we had to put in our first warranty claim and we were so lucky that Antony T. was our tech on site. He went above and beyond as the temps in Denver were starting to get really really cold. Our furnace needs to be replaced, and on his way back into Denver he brought us space heaters to help the situation. We are so grateful for his kindness and will for sure be using McCormick's again in the future!
My second shoutout is to Shelby in the warranty department, she was so helpful and really was the calm in this situation that we needed. She was so understanding and very knowledgeable about next steps. We truly appreciate her!

Unfortunately I got Nick twice late at night The first time I had to remove a shelf and he couldn't wait 5 minutes to do so but I guess when you send a service tech out at 7:00 p.m. I wouldn't want to be working at night either. Unfortunately because he didn't fix it I waited 3 days they still had not made an appointment Nick still had not told them what had happened so they had to make a rush appointment to fix my air conditioner. Well guess what they sent him at 6:30 on a Friday night! He came in the door looking like he had already been beat and had nothing good left. He proceeded to b**** and complain and treat my wife with disrespect. After walking through the house three or four times and asking me for dental floss he finally left mumbling something under his breath not even doing it politely interrupting us right in the middle of the meal by standing there weirdly and awkwardly and then starts mumbling and I ask my wife what he said and she said I thought maybe you knew? I'm left with a mess on the floor trash all over from what he did??? As a contractor if I did that I would not have a job! This guy was completely unprofessional in every aspect and unfortunately did not do the job but like I said what company would send somebody at 6:30 on a Friday night? Unfortunately I will be an air company kind of frustrating as a business owner with several rental properties looking for a great heating and air company and their technician to me is a representation of the deficiency of their company! I will be looking else and would recommend you doing the same! It was a very unfortunate experience that left us without air conditioner in 90° weather for over 2 weeks because of the laziness and lack of detail of Nick!
