Is this good for 1200 sq. ft. house?

Single story 1200 sq. ft. home will it sufficient?
Asked by: mellow1
To properly calculate furnace size, you need to know house size and construction, location, heat loss, etc. Since a furnace replacement is not really a weekend DIY project, I would suggest you speak to a qualified HVAC contractor.

Customer Reviews

40,000 BTU 80% Multi-Positional Gas Furnace is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from good product We purchased an a/c system with a gas furnace. When it was installed the air handler wheel was out of balance and made a loud noise. It was replaced free of charge & is working very well with no noise. In my opinion this is a good product.
