I used Complete for my furnace checkup two years ago; it's time for another checkup, so I scheduled one for this month, and asked for a quote on installing a heat pump as well. On the assigned day nobody showed up. A couple of hours after the appointment time I called and left Tim a message, but no response. Called and emailed several times over the next week, but absolutely no response. Not sure what's going on - maybe they're all out sick or the business has folded, but if not then with such poor customer service they deserve to go out of business! Very frustrated with Complete

Tim was able to arrange for a visit over the weekend on a cold day for complete resolution of a serious issue with our furnace (because of another company's faulty installation and failure to respond to warranty requests). Honest assessment, great advice, and courteous service. Highly recommended.

I have relied on Tim from Complete Mechanical since I purchased my first home 8 years ago. I contacted them upon recommendation from a friend and I must say I have been happy with their service since day 1. My furnace is the original that was installed in the house when it was built in 97, so upon purchasing back in 2012 I already believed it was due to be replaced. Complete Mechanical was honest and upfront from the beginning, they have kept my furnace serviced and running with annual check-ups. Regardless of which employee I have worked with they have always been courteous and timely. They did
