Great work, I would highly recommend this company for any project you may have. They were very transparent with pricing. I was glad they were willing to make sure they could repair AC vs trying to sell me a new one. To me this show honesty and will definitely continue business with them!!

Airconditioning went down right before a week of 90-degree temps. Paul Allen from Grays came out asap, walked me throught he issues, gave us an extremely competitive qoute and had our house cooling off before we knew what was happening. Great company, worth trying them out!

I just had a new Trane AC system installed the other day by Grays Mechanical. Paul who came out, explained everything, answered any questions and gave me estimate on the spot. He was delightful to work with and did not try to push anything on me I didnt want.The 2 gentleman that installed the unit were great. They were both polite and thoughtful of your home. The install went very well.The new unit is very quite. We also installed a new ecobee thermostat which I can set the fan control to run 15 min every hr to mix air in house. Our house has never been more comfortable.Give them a call you wont regret it!!!Thanks again Paul and Grays Mechanical!Greg G. - Oakbrook Terrace
