Fresh Air Intake In Attic

The draw from the intake in the attic will pull hot air from the house up into the attic.

Fresh air intake in attic.

I am still constrained to run the fresh air intake via the soffit attic garage into the basement mechanical room. I am in zone 5a and the garage is outside the thermal envelope. 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. 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.

A return air intake is where air returning from the conditioned areas is inducted into the air handler or furnace. Hey fresh air is good right. Do not use gable vents because it s possible to draw rain and snow into the attic. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

If you have a fresh air intake the air is immediately replaced with fresh air from outside the home. This results in a constant upward air movement due to the buoyancy of warmer air. Any negatives to exhausting stale air simply into the garage instead of extending the exhaust pipe via the garage and attic to the exterior.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. Beneath the filter was a hole cut through the fiberglass ductboard plenum. So i ll assume you mean your sealed attic has a return air provision. Use only soffit vents as fresh air intakes for powered attic ventilators.

Hot air exhaust vents located at the peak of the roof allow hot air to escape. Bathroom fans and window box fans commonly pull outside air into your home so they should be shut off during a fire advisory. Do you want to lose heat. 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.

In all seasons the attic space is warmer than the outside air. In vent attic roof vent is an on the rooftop intake ventilation product that lets fresh air in when traditional soffit vents are out. 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. The indoor portion of your unit has an air conditioner return air intake usually located on the ceiling.

The filter was there to filter the fresh air they were using to ventilate the home. This return air intake grille typically includes some type of filter to keep dust and debris out while allowing air to pass through. Keep bathroom fans and window units turned off.
