WHAT our satistied customers have to say

I couldn’t find this company on Yelp to review them there where more people might see it, so I’ll just do it here. I was referred to Marcus by my cousin who uses him for real estate transactions, and while all I needed him to do was a preventative check on my HVAC unit before the HOA turned the chillers on for the summer, he went above and beyond and fixed a minor irritating problem with the unit that had been bugging me for years, and his price was quite reasonable.

I came away with the impression that he is exceedingly competent, and he explained various aspects of the unit and what he was checking for and doing to it as he went along, which I appreciated. If his repairs are anything like his maintenance check ups, I doubt if you can find a much better technician for the money. I highly recommend him!

-Chip Edwards

Great Guys Heating and Cooling was a referral from a friend. When my A/C unit stopped working on the hottest day of the year, I had another company come out and try to charge me my first born child as payment. Don’t waste your time anywhere else! I repeat-DON’T call anyone but Great Guys. Marcus was so knowledgeable, extremely professional and most importantly honest. He told me exactly what was wrong and charged me a fraction of the price the other guys… the following day, I noticed the A/C still wasn’t working to the best … I called Marcus and he made it a point to be there that day and he noticed that a step had been overlooked, he quickly fixed it, owned it, and simply took care of it. No if’s and’s or but’s about it. Just honest work and a honest apology. I will never use anyone else. I can’t thank Great Guys enough.

-Mackensey H.

A cool breeze of a dream come true! After 6 A/C installation quotes, Great Guys held true to their name and stood out above the rest. Absolute pleasure dealing with Marcus. Extremely patient and just is an overall Great Guy! Very high level of integrity and wants to genuinely help provide the best application/solution that fits your setup & wallet. … I highly recommend Great Guys and will be having them tend to all my HVAC needs going forward. Shout out to the install crew, Maddy and Jordan! Flawless experience from the initial contact to when we sparked up that cool air flowing through those less noisy ducts that they helped me out with also!
