and A/C. 2 of 4 bedrooms have poor heating
and cooling. First bid suggested to have fans
within the ducts going to those rooms and
replace furnace with Carrier and 3.5 tons A/C. Second one suggested to increase CFM to 2000 with Lennox and 5 tons A/C. Third one
suggested to have a two stages lennox with
3.5 tons A/C. I heard that fans in the duct
are noisy and high CFM will shake duct. Anyone familiar with 2 stages furnace?
suggested to increase CFM to 2000 with Lennox
