 Trustindex verifies that the original source of the review is Google. Great service.  Tech was very knowledgeable and showed attention to detail.  Took pictures and explained the work performed.  Most companies do work and hand you a vague report.  Smart Heating and AC is very thorough.  Will more than likely use service again.
