Testimonials
Harold McGee
I can recommend Tri-County Heating and Cooling without reservation. From the initial contact, when making an estimate of costs, Ritchie was very clear as to what his quotation included and what it did not. After having made the contract he was very quick in getting all the relevant parts and in preparing the site for… installation of my heat pump. The site was a low ceiling utility area in which he, and his crew, worked efficiently to clear out an existing electric furnace and to install the new heat pump. He was very good in explaining the reasons for positioning of the external unit and pathway for connecting the two units; as he was in explaining why a wireless connection between the thermostat and the internal unit was better for my house rather than a hard wire. I was very pleased with his knowledge, his skills, and his business sense. However, he continued to make himself available to explain questions I had about the operation of the unit and he made himself available at any time when there were some problems with circuit breakers triggering frequently. Again he was resourceful in trouble-shooting the problem and finding a permanent solution to the problem. He will not abandon you once you have settled the bill. He, and Julie — his wife-business partner, are good at what they do and act with integrity and good will. They are good models for how a small business should operate. I wish them all the best in serving the tri-county area. Read more “Harold McGee”
