Attic furnace ventilation.

The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber. The top of the t has soffit vents and a ridge vent. Attic fans perform this ventilation by pushing hot air out into the environment while also pulling fresh cool air into the attic. The roof is a t shaped gable roof.

If you are unsure if you have this style the big clue is in the venting. So why put an hvac system up in the attic at all. The stem of the t has soffit vents and no vent at the top. The furnace is located in the stem.

Insufficient ventilation can lead to moisture problems during the winter and decreased energy efficiency during the summer but too much ventilation can be just as bad if not worse. You might not receive the same air movement benefits if the unit is in a garage either. New high efficiency furnaces can have efficiency of about 95 percent a huge savings for your wallet. I have a goodman 93 high efficency natural gas furnace located in my single story home in the utility room.

Hi everyone i ve visited this site a couple times but this is my first post. Utility room is not closed off in any way to the rest of the house.

It comes on an easy to install flexible mesh roll and is hand nailable with no complicated fitting wrapping nail gun adapters. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.

The result is a cooler attic space with plenty of air exchange. The roofers installed 4 passive roof vents 3 being in the area of the furnace in the attic. Newer high efficiency furnaces do not always have vent pipes that exit through the attic space. If you don t have a crawl space or a basement then it can be a challenge to place a furnace on the ground floor of the structure.
