 Trustindex verifies that the original source of the review is Google. Highly recommend Advanced HVAC Inc.  I was very pleased and impressed with the service from beginning to end by the office and technician Alex.  Alex was very prompt, friendly and so very helpful.   So nice to have found a place I can rely on to handle any natural gas issues I have.

 Trustindex verifies that the original source of the review is Google. After an Enbridge tech could not solve a gas leak and shut off my gas, Marc  made time in the schedule to attend my emergency. He found the problem was on the Enbridge side of the meter.  I still had to pay but good to know some people are dedicated to helping.

 Trustindex verifies that the original source of the review is Google. Could not have asked for a better experience - we purchased new equipment after our air conditioner gave up during the latest heat wave. They understood our urgency and were very proactive in making sure we were scheduled in for a quote and installation quickly.  The sales team gave us a number of options and really listened to what we were looking for.  We had multiple conversations and they were always quick to provide any information we asked for. Installation was great - the team that came to the house was incredibly professional and very personable.  They did excellent work and left the furnace room and areas outside where they worked spotless. Pricing was fair as well.  Would 100% recommend Advanced HVAC

 Trustindex verifies that the original source of the review is Google. Very good. The technician came on time, was totally organized and on the job. He got the whole inspection and servicing done quickly and left no mess behind. He kindly put shoe covers on, didnt mind the cats watching him - highlight of their day - and was a super friendly guy. We came over from Clement Marchand when that company was closing down and I am happy with the seamless transition. There was absolutely no upselling and the whole experience is as good as we ever got with Clement Marchand ( who we were with for 25 years) . I am happy and I think we will stay.
