Verified record
AMT HVAC, Corp. is a Haverhill, Massachusetts HVAC contractor run by owner Steve Nguyen, offering residential and commercial heating and cooling installation, repair, and maintenance, with authorized or preferred dealer status for several major equipment brands including Trane, Carrier, Mitsubishi, and Fujitsu. Some reviews and the BBB profile refer to the business as "AMT Comfort Air HVAC, LLC" or "AMT Comfort Air" — the same phone number and PO Box address confirm this is the same business under a related or prior name. The written track record is extensive and, with one striking exception, overwhelmingly positive: 25 reviews on HomeAdvisor and Angi span 2009 to 2023, repeatedly praising Steve's promptness, honesty, and technical skill on jobs like central air installs, heat pump replacements, and a 2021 boiler installation described as prompt, professional, and amazing. Most of that detailed praise dates to 2009-2015, with only a couple of reviews since. Set against that record, two BBB-published reviews allege serious misconduct, calling the business's workers "criminals," without giving any specifics about what happened. That is a sharp, unresolved conflict with the specific, consistent praise on file elsewhere, and anyone considering this contractor should ask directly about it rather than assume either side tells the whole story.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from AMT HVAC, Corp.. Use it to sanity-check bids, then get the real number in writing.

I'm going to hire somebody from Angi again. You guys did a great job.
AMT was prompt, professional and did an amazing job installing my boiler. I wouldnt call any other place. Steve was great and explaining everything and went out over everything with me. I would definitely recommend AMT for anything you need.

Steve was the epitome of professional: he was prompt, informative, thouroughly explaining the issues and solutions and future items that we should be aware of. He was sensitive and affordable. He even followed up after the work was done to make sure all was well. Would i use his service again? Yes, yes, a thousand times YES!
