I happened to call for service on a wall unit heater the very day they added that particular service to their offerings. It's hard to find a company to work on wall units, so I was both happy and a little hesitant as they were new to this kind of service. Nick came and with a little tinkering found an obvious problem. We had just purchased the house so we had no idea what we were dealing with. The unit stopped working again a few days later, and he came back to diagnose that we just needed to rebuilt the thing. No surprise, we talked about it previously and knew that was a possibility. We ordered parts, waited, and they came and rebuilt it a couple of weeks later. Great. Heat restored. A few weeks later it stopped working again. Ugh. Nick was awesome though. We came back on the very day we called and found a sagging wire, no charge, of course, as everything was under warranty. Super professional and really nice. I will use them on our other properties, and I would highly recommend them. Our repair ended up getting about 50% of the way there to just purchasing a new unit. In retrospect, I think I'd just go with a new unit and be done with it for another $1k. Live and learn.
