Customer Testimonials

"When Nick came to our house to install our boiler unit, he was professional, knowledgeable, courteous, and his work was neat and precise. Any contact that we had with the main office was enjoyable and informative. We would highly recommend McCormick for any work to be completed, whether if would be a small or large project."I wanted a second opinion on my furnace, so I called them. This company is the most professional contracting company I have had at my house. The tech knew what he was doing, and he explained everything and even told me how to prevent future problems to save me from potential costly repairs. Highly recommend.

"Jesse and Nick were amazing. They tried everything to get our unit running with the simple inexpensive fixes first. Unfortunately our units are just too old (which I knew they were), so Nick and Jesse have installed new AC and furnace. The house air movement feels amazing considering we haven't had it on these hot days. And now for winter I know we will be safe and warm. They were professional and took care to get the job done right. I would recommend these guys any day of the week! "

"We had our heater go out in the middle of the night, we call the next morning and McCormick came out to our home within and hour! The service was first class! We recommend McCormick AC and heating with 5 starts! Thanks for taking care of us."Our furnace was really old and too costly to keep repairing, so I called for an estimate on a new unit. They came out for free and gave me a great price on a new system. Their service guy explained the process and details clearly. There were no unexpected charges; they completed the work the same week, and done in only a few hours. New system runs perfectly couldn't ask for a better company."
