    Clear example of “you get what you pay for.”

    No one enjoys having issues arise at the home but when we have needed their services they’ve been exceptionally fast and thorough.

    John got here really fast today with a pressing matter and we really appreciate their warranty servicing as well.

    This was the most professional company of the 3 I contacted for HVAC service. Phone etiquette was phenomenal and helpful. Scheduling was a breeze with the day and time window options. Mario was excellent, again very professional and patient when explaining the issue and options. He was able to do a band-aid repair to buy us time before committing to one of our options. I will definitely use GRC for any future business. ( We have a 60 year old Carrier HVAC which runs like a workhorse. We prefer to refurbish rather than replace).

    Recently used GRC to replace our HVAC system in our condo. Not only did they offer the best price, their entire staff was incredibly responsive and helpful. They also made sure they were able to install our new unit before the next heat wave. The technicians Terry and Justin were on-time and did an amazing job with the installation. I'd absolutely use them and highly recommend them - thank you!
