Fresh Air Intake In Attic

Homes without a fresh air intake close to a conventional furnace will often draw air in from attics crawl spaces dryer vents and a host of other unconditioned spaces that reduce the quality of the air you and your family breathe.

Fresh air intake in attic. Bathroom fans and window box fans commonly pull outside air into your home so they should be shut off during a fire advisory. The filter was there to filter the fresh air they were using to ventilate the home. I am in zone 5a and the garage is outside the thermal envelope. When the system runs it pulls return air from the conditioned space in the home and it also pulls a significant amount of air from the vented attic.

Hot air exhaust vents located at the peak of the roof allow hot air to escape. A return air intake is where air returning from the conditioned areas is inducted into the air handler or furnace. This return air intake grille typically includes some type of filter to keep dust and debris out while allowing air to pass through. This results in a constant upward air movement due to the buoyancy of warmer air.

And reading your post further i think you are trying to use the entire attic as a return air plenum with openings in the house below to allow air to return to the unit. Oh and when you have an intake pipe installled into the attic it does not terminate in the attic it terminates at the combustion unit. Use only soffit vents as fresh air intakes for powered attic ventilators. I am still constrained to run the fresh air intake via the soffit attic garage into the basement mechanical room.

The air passes through the filter of the unit and quickly passes over the supercooled coils inside. So i ll assume you mean your sealed attic has a return air provision. The draw from the intake in the attic will pull hot air from the house up into the attic. Beneath the filter was a hole cut through the fiberglass ductboard plenum.

In all seasons the attic space is warmer than the outside air. Fresh air intake inducts fresh air from the outdoors. Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. In vent is ideal for roofers and remodelers who need to add attic roof intake ventilation to balance their ridge vents but can t access the soffits or overhangs.

Do not use gable vents because it s possible to draw rain and snow into the attic. Any negatives to exhausting stale air simply into the garage instead of extending the exhaust pipe via the garage and attic to the exterior. Typically the fresh air intake will be located in your attic or ducted to the return side of the home s central air handler. The indoor portion of your unit has an air conditioner return air intake usually located on the ceiling.

Keep bathroom fans and window units turned off. If you have a fresh air intake the air is immediately replaced with fresh air from outside the home. Do you want to lose heat.
