warnei Lopes2024-12-12 super professional, we changed the hvac system in my house, everything perfect!!! Joe Miller2024-10-10 Diogo is one of the most professional vendors I have ever worked with. His communication is unmatched and his work is always perfect. He will walk you through and questions that you may have and is also a great person to be around. I will be using St. Joseph HVAC for as long as possible!! If I could give 10 stars I would! Thank you Diogo!! asiawebber2024-10-07 St Joseph’s executed all HVAC work for my major home construction project that was completed last Spring. They successfully installed a very complex system in a very old house. It works perfectly. We are very pleased with the ongoing support and maintenance work we’ve had, as well. Luke Chiccarelli2024-04-19 The guys at St. Joseph were great to work with! They were always friendly, responsive and reasonably priced. Showed up when they said they would and work was done to satisfaction. I would highly recommend. Michael Josephs2023-11-03 St. Joseph’s HVAC was great in helping me select a proper mini split for my home. Installation was tidy, fast, and done with care. I’m very happy with my unit and highly recommend Daniel and his crew. Brett Cochran2023-10-02 I found the team via their advertising on Next Door. I was about to put a down payment on a contract with another, larger, installer in the area and figured it would be great to get a quote from an owner/operator business. In my experience, O/O businesses tend to stand by their work better and offer more fair pricing. Compared to the quotes I got from 3 other larger installers, St. Joseph was thousands less. With the generous state rebates, the bigger installers are happy to charge as much as possible to turn those rebates, meant for the customer, into pure profit (crooks!). St. Joseph was on site within 2 weeks to do the install. The bigger guys were booking 1-2 months out. St. Joseph worked with me to move my condenser locations and answered all my questions. My installation was for 2 3-ton Bosch IDS heat pumps to replace 20+ year old AC units. I did all the paperwork for the rebate but wish I had St. Joseph done it instead since it wasn't the most straight forward process. Orlys Machado2023-09-20 I highly recommended St Joseph Heating and Cooling services. I’m a project manager with several different properties throughout Massachusetts. I feel blessed our path has crossed, when I desperately needed someone to fix what others failed to do it. St Joseph Heating and Cooling was able to correct others mistakes, while delivering outstanding customer service. I have used his company several times, and have always experienced the same consistency in service. Thank You for being reliable in this very unreliable line of work. marcio andre2023-08-26 What a team! Prompt response to a time sensitive request, friendly staff on the phone and in-person, technician arrived on time and completed the work quickly. They were professional and answered all of my questions. St Joseph Heating and Cooling team were exceptional and I would highly recommend them. THANK YOU! Jodi Swartz2023-08-08 A contractor I know referred St Joseph’s HVAC to me - On one of the hottest weeks of the year, this company answered the call. They priced the project fairly and two days later, I had a new heat pump servicing both heating and A/C. Best is that I ended up with a working 2 zone system! Daniel also explained the rebate system from MASave Highly recommend!
