"It was a wonderful experience working with Joseph!! I called him to see if he could come out to check my furnace as it was not working, and then cancelled because it kicked back on for a bit. I got home from work and realized it wasnâ t working again so contemplated calling him to come out again but didnâ t as I had lots of other things going on. about 5 minutes later I got a voicemail from him asking if everything was still working and he let me know he was around and could stop by. I called back and he was at my house 15 minutes later. I am a first time homeowner so obviously have no idea what Iâ m doing with a furnace and he was so informative and really just the kindest man. Considering I called out of the blue and he had no idea who I was, i was really impressed."
