row review about company Wilson's Plumbing & Heating

I had Wilson's come out to examine a furnace that was 17 years old. I did my homework on the parts (the electronics were shot) and knew the new board would cost about $100-$150. Assuming labor for a few hours the repair should have been $350. The quote was for over $500. I was also considering switching out the furnace to a newer more efficient model and asked the Wilson tech for an estimate: The estimate was $3500 for 65k BTU. You can buy a 90k BTU with 80% efficiency for about $900. I had a new 90K BTU unit installed with new duct work and filter system for $1900... Do the math
