The New A/C is Wonderful

Excellent service from beginning to end. The new A/C is wonderful.

J.M.

Installation was First Rate and Professional

Tom did a great job. Got 5 other estimates: one did not respond, another sent a proposal via email which I could either accept or decline with no questions entertained. We had a special situation and only Tom was able to understand it and figure out a way to do the job. We're very happy with our new Daikin unit-operates exactly like Tom said it would. The installation was first rate and professional as well. Would certainly recommend.
