Attic Furnace Ventilation

Hi everyone i ve visited this site a couple times but this is my first post.

Attic furnace ventilation.

There are 3 gas furnaces and ac units. The stem of the t has soffit vents and no vent at the top. 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. New high efficiency furnaces can have efficiency of about 95 percent a huge savings for your wallet.

Well mainly it s a way to save space. You might not receive the same air movement benefits if the unit is in a garage either. Recently moved into home in eastern ma zone 5 and have a 2 story 3k sqft home. The roof is a t shaped gable roof.

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. Just like properly sizing your furnace and air conditioning unit you want precisely the right amount of attic ventilation for your home. When installed as part of a properly balanced when installed as part of a properly balanced attic ventilation system gaf cobra exhaust vent is a shingle over exhaust vent installed at the roof ridge that helps exhaust excess heat and moisture from your attic.

A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace.

An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. Newer high efficiency furnaces do not always have vent pipes that exit through the attic space. The result is a cooler attic space with plenty of air exchange. 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. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber. Original installers used pvc to vent the furnace to the roof but combustion air for the furnace is pulled from inside the house.

So why put an hvac system up in the attic at all. The furnace is located in the stem. When you place a furnace in the attic to take advantage of its. If you are unsure if you have this style the big clue is in the venting.

Utility room is not closed off in any way to the rest of the house.
