Lesley Small from Delta

did some preliminary work on type and size. I found HD staff very helpful to determine the correct model given the type of use and the quiet level (open, smaller house) we required. They directed me to a less expensive one than I had considered and it has been great - operational for 6 months and was straightforward to take out my old and replace this one - less than a 1 hr job with the guidance they gave me at the store.

Used an online coupon to get an annual service. Tech came and quickly saw we had an old furnace and went back and got out the carbon monoxide meter. It gave a reading of 3 and then 4 at a vent - he said that under law he must 'red tag' the furnace but wouldn't and then offered a replacement pricing. He said cleaning was a waste and took certificate and left a replacement quote. I did get second and third opinion that were quite different. I was very disappointed in tact taken by the technician as we are considering a new furnace but will not buy from them!
