Moving Attic Ac Duct

Can you put your air conditioning unit in the attic with blown in insulation.

Moving attic ac duct. Required tools for this project. Seal all the joints with aluminum duct tape or duct sealing caulk. Locate the screw sticking up through the ceiling and mark this with tape for reference. Ductwork for air conditioning and heating systems consists of supply ducts that dispense air and return ducts that draw air.

Return air ducting is necessary in almost every room. Attic hvac systems save space. An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. These ducts terminate at grills on the ceiling or walls in a room.

Have to get the air back to the furnace. When that conditioned air is moving through the ducts the second law of thermodynamics comes into play because we have a temperature difference between. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. When you decide to trade in your room air conditioner for central air you ll have decisions to make including where.

If the new ducts provide enough headroom just deliver the old ducts to the contractor to use as a template for the new ones. These ductwork tips will help balance your air conditioning and heating system. So why put an hvac system up in the attic at all. Map out the current a c ductwork by going up into the attic or crawl space.

According to nrel researchers david roberts and jon winkler moving the ducts from a vented attic to a new location inside the conditioned space will reduce electricity used for cooling by 15 to 20 and will reduce the size of the needed air conditioning equipment by 0 5 to 1 ton. In more cases than not a 3 ton ac with the ducts in the attic has a ton or so of load that s just from the location of the ducts in the attic and the associated duct gains leakage etc. I believe that moving ducts out of the hostile temperature environment of the attic is obvious. Hvac ductwork sizing is critical for proper heating and cooling in every room.

Instead i covered my attic ducts with insulation. The remaining 2 tons of capacity is at least 1 5x oversized for the actual 1 load. However unless you have new construction is highly doubtful that you can find an alternative. I chose unfaced batt type so that it would stay in place.

Find the ductwork that leads to the a c vent that you wish to move and mark it with colored tape. Well mainly it s a way to save space. It s to move heated air in winter and cooled air in summer.
