    "Kevin honestly saved our Christmas. Another company had been out and said we needed a new part in order to get our furnace going again. The problem was that the appliance stores were closed for the next 4 days for the holidays. Kevin came and determined it wasn’t a problem with our furnace but rather our thermostat. He then went out to buy a replacement and installed it himself. I wanted to cry happy tears but kept it together for the sake of not making it awkward, haha. On top of that, he was friendly, patient with my 1 year old who was obsessed with him, and so affordable that I had to double check he charged us enough. I’m a customer for life."
