What do our customers think of us?
The New A/C is Wonderful
Excellent service from beginning to end. The new A/C is wonderful.
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.
Very Happy with Your Work
Very happy with your work, just very happy I haven't had to use it yet due to cool weather.
Installed as Promised in a Very Timely Fashion
The customer service has been excellent. It's been extremely easy to schedule the consultation, installation and follow-up service. Everything was delivered and installed as promised in a very timely fashion. I've been extremely happy with the level of communication from your company. When I'm ready to have the next phase of my HVAC system installed I'm definitely coming back!
Very pleased to date!
