Williamson-Thermaflo Furnace Reviews
Unbelievably tough unit. No problems.
"Do not buy a Williamson"
They do not support their warranty. I had a lifetime warranty on the heat exchanger. It failed and I had to pay $1,700 to replace it. Williamson will not pay anything for this faulty product. Do not buy a Williamson.
