Tim installed a 6 zone heat pump system in my house that involved a lot of planning to get it done in an attractive and effective layout. He did a great job. The pricing was competitive and the communication throughout the project was more than I could ask for.
Tim and his crew were fantastic. We had an issue with a heat pump water heater blowing cold air into our bedroom and Tim installed a duct to rerout the cold air upstairs, fixing the issue. The work was done very professionally and efficiently. Highly recommend this company.
Tim and his crew of dinosaurs helped us do a complex oil to natural gas conversion. He helped us navigate the many tradeoffs between cost, system effectiveness, and aesthetics. The crew is clean and respectful, and handled all the necessary subcontractors. We’re very happy with how it turned out, would recommend.
Tim and team did a great job converting our failing, oil burning heating system to natural gas. They are highly efficient, knowledgeable, professional, and responsive. Definitely recommend!
Great experience today with Tim. I called him concerning a possible odor coming from one of the heat pumps that Tim expertly installed a couple of years ago. He called me back immediately and was at my house within 30 minutes. He quickly determined that the odor source was not coming from the heat pump and possibly from an electrical appliance. The odor has since dissipated and all is well. No charge visit. He wouldn’t even take home made cookies!
