very unprofessional could not even get a quote. would not return calls, and never came up with an estimate. so they must be pretty good, because they surely don't need my business.

This company is very professional and straight forward. You will not get a better deal in town and unlike a lot of other companies in the area Pro Tech will not try to sell you things you don't really need just to make more money. Best customer service- Orban and Tom area fantastic to work with.

Great service

Installed central air stood by their quote even when they ended up having to do a lot more!! And a couple years later had them do a tune up and check everything for a reasonalbe price. And went above and beyond to make us happy. Thank you Pro Tech!
