"The service technician was great!"

"Highly recommended! Jason makes sure everything is right and also uses some technology for metrics. Most HVAC people I’ve dealt with, didn’t so, you had no baselines for references and just their word. My AC is fixed now and blows super cold!"

"Nate was amazing! He inspected and worked on my homes air conditioning unit. He was so pleasant, friendly, knowledgeable, and informative... he took the time to explain all the work he did and recommendations on what needs to be done in a way that I could understand. He talked about the different options I had on future upgrades/replacements/repairs and their cost without any pressure on buying them NOW... I am so pleased with this experience and plan on using this company in the very near future for some of Nate's recommendations... In addition, Nate refused taking a tip ! Trustworthy & Honest with EXCELLENT CUSTOMER SERVICE SKILLS!"

"Technician diagnosed a bad capacitor; replaced it, cleaned the coils, checked the efficiency of the outdoor unit provided helpful maintenance/cleaning tips that will extend the life of the compressor."

"Wonderful! They responded almost immediately and quickly identified the problem being in my wiring. An electrician had rewired some of the electrical panel and that was what had caused the air conditioner to quit working. I had called the electrician, but he couldn't help me. I was so impressed by McCormick Heating and Air diagnosing the problem and fixing the same day!"
