We had Kalapi and his Tech's, Gaurav and Pankaj come and install a heat pump and a heating system at our home in Peterborough. These gentlemen were amazing, knowledgeable and very professional. Our project took a bit longer because of its complexity but the techs made sure everything was working 100% efficiently AND they made sure to clean up all the mess. They explained the operations of the entire system and made sure I knew how everything worked before they left. I highly recommend Kalapi and the crew at ThermEnergy for all your HVAC needs.
