Our tech arrived on time, even a little early. Friendly smile, and professional. He vacuumed up any mess and was done. COTE’S Team, and we have seen a lot of different ones over the years because our factory installed system was horrible. He is actually the same tech that came out about his time last year. In the summer of 2017, after we had our new roof installed from the hail damage that March, our tech found and repaired issues the roofers made, and then ignored that could have caused carbon monoxide to flow into our living space. Thank goodness we hadn’t had to use our heater but a couple of times before he found and fixed the problem. Very scary!
