I booked The Appliance Guy for a dryer repair based on his reviews on this site. I've used him now for two different jobs (clothes dryers in 2 rental units) and I am throroughly impressed.
I don't say this lightly, but Joe is a master at his craft. He knows his machines.
We've been having problems with a dryer that I had bought used/re-conditioned. Joe came and I was quite satisfied that he got it working again, but Joe himself still suspected that something more had to be done. On his own time (after I had already paid) he researched the problem further. From his research and from memory, Joe diagnosed what must have been wrong. (He remembered that there was a part that didn't belong, likely from when the dryer was being reconditioned). Joe asked if he could come back to tweak his repair.
This is what I mean by a master at his craft.
