I had been a customer of Comfort Masters because the previous owners of our house had used them. We had a board on our furnace fail and CMs came out and totally dropped the ball and sent a very nasty technician who didn’t feel he had to explain anything and had such a poor attitude. I called Lennox (furnace maker) to ask who they recommend and they suggested TopTec so I hung up and called immediately. My appointment was set within minutes for my first choice and the following day Juan (our technician) arrives. He was extremely professional, empathetic of our situation and after I described the problem, Juan asked a few questions and collected all the information from me and got to work. Juan then went down to look at furnace and quickly returned with what he diagnosed. He explained everything and as soon as I was in the loop, he got on the phone to locate the part. He found it, quoted price and told me he would be back tomorrow morning with part in hand to complete the repair. Rather than leave me hanging over the weekend with no heat or A/C, Juan drove and got the part so he could return on Saturday morning. He arrived on time with new part and within 10 minutes the problem was 100% fixed and he also stayed around to help with the thermostat app and answer questions. He was such a friendly, efficient and knowledgeable technician and was really happy things went south with Comfort Masters as we now plan to use TopTec for all needs beyond HVAC. Couldn’t recommend Juan and this company any higher and suggest that if you are somewhat unhappy or untrusting of the company you have been with for some time, give TopTec a try and you will be relieved and in good hands. Thanks Juan!
