Trusted HVAC is a family-owned South Shore HVAC company that says it has served the area since 2021, with owners bringing more than two decades of hands-on trade experience. The company offers heating, air conditioning, air-quality, mini-split, and emergency HVAC service for residential and commercial customers, and describes itself as fully licensed and a registered Mass Save contractor. Reviewers repeatedly credit Josh, working with his son, for accurately diagnosing problems other HVAC companies couldn't solve. Recent reviews describe finding a $400 fix for an air-conditioning problem after another company quoted $19,000 for a full replacement, and a full HVAC system installed in a newly purchased Scituate home after Josh's professionalism won the job over competing quotes. One reviewer with three different heating and cooling systems from three brands said Josh diagnosed issues that had stumped several previous technicians. Earlier reviews from 2024 and 2025 describe a boiler and piping replaced within 24 hours after another company took nearly a week without a fix, mini-splits installed with a quick turnaround, an oil tank replaced in a few hours, and gas boiler and fireplace piping work described as reliable and easy to work with. Trusted HVAC is a strong choice for HVAC installation, repair, and emergency service across the South Shore towns it serves, particularly for complex or previously misdiagnosed heating and cooling problems.

Incredible service! Fixed a $400 AC problem when another company quotes us $19,000 for a new unit! We will build a shrine in our home to Trusted HVAC!
Josh and his son installed a new full HVAC system in a home I recently purchased in Scituate, MA. Josh’s knowledge and professionalism were why I gave them the work after getting several quotes, and their work exceeded my expectations. Clean, fast and excellent quality work - I highly recommend Trusted for your HVAC needs.
I have an old house with three different systems (one traditional natural gas, and two heat pump) from three different brands. I had cycled through multiple HVAC guys who were stumped by multiple issues I've experienced. Josh figured it all out, and figured it out quickly, including on the Hisense system he was not familiar with (with a Hisense tech on the phone). Diagnosing and fixing two separate issues, including required parts for both, cost me less than $1K. What a great experience, and a great find.
We had an issue with our heat pump and couldn't get the installer to come out and fix it. After talking to our neighbor who had Josh fix their heat last winter during a cold snap and came highly recommended. So glad we got his name because him and his son came right out, very clean and professional and most importantly honest about the work that needed to be done. Since then we have hired Josh for other plumbing work in the house and he has been a pleasure to work with. Can't say enough good about these guys. Its hard to find reliable contractors these days.
We have worked with Trusted HVAC for multiple service calls at our business. The experience was outstanding from start to finish. Josh's response time was incredibly fast, and he was able to schedule and complete the service much sooner than expected. The pricing was very fair and competitive, especially considering the quality of work provided. What really stood out was how thoroughly the technician explained every step of the process — from diagnosing the issue to outlining the repairs and maintenance recommendations. It gave us complete confidence that the job was being done right. If you’re looking for a reliable HVAC company that values honesty, efficiency, and customer service, Trusted HVAC is an easy choice!
