I recommend everything about this company. Customer service, punctuality, and expertise. Checked over issues with our furnace, found the problem, ordered the part, and fixed it where another high end company couldn't find the problem. All I can say is THANK YOU!

We have now had two homes taken care of by these great folks. One we sold in August, and the one we purchased. Every single person from office staff to installers is knowledgeable and thorough, personable and efficient. Pricing was also amazing. We used mini splits in our old house to install a/c for two floors. Our new home, circa 1987, all electric! is now heated and cooled with mini splits as well.

We also installed a heat pump electric water heater for savings. We love these systems! Information about MassSave was immediately shared, and the paperwork taken care of by them as well. One rebate has already come! We highly recommend this team. Fabulous!!!
