Forced Hot Air Heating System In The Attic

This will keep your attic cooler which will reduce the cooling load on your home.

Forced hot air heating system in the attic. An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. If that won t work because of space limitations the contractor will fabricate a separate sheet metal plenum. It s supposed to be pulling air in only from the house but because of air leaks it also pulls air in from the garage. Most of the issues that furnace might experience in an attic are due to extremely cold weather in this poorly insulated space.

A furnace can suffer from a drop in energy efficiency if it s in an unconditioned space such as an attic. Air from the garage can easily get into the house. This one s not as bad as some that i ve seen. That s because more families are discovering only miller furnaces offer such incredible efficiency and comfort plus lots of other value added features.

Forced air systems are usually the cheapest ones to install in homes today and a furnace qualifies as this type of system. Heat pumps and ducts are part of it too. The furnace may be in a garage attic laundry room or interior closet for accessibility. Sometimes it goes right into the existing plenum.

When the heating and cooling system is running it s pulling air in. That grille you see there is a return vent. High efficiency furnaces aren t usually recommended for an attic. If you don t have forced air the fan and coil system is typically placed in the attic where it will deliver cool air through ducts.

The drain must be installed through the core of the house as water will be flowing during the colder months. This is a coating material that gets sprayed onto the outside of your roof to help reduce the amount of heat that is radiated into your attic. Indoor air handler comprised of the central a c evaporator coil and blower this unit is typically mounted in the attic or a dedicated hvac closet in retrofit scenarios. Since most homes have their hvac system serve multiple functions at once it can be cheaper to install the unit in the attic because the roof access can make inspections maintenance and repairs at lot easier.

The heat ducts usually travel in the walls behind the drywall and exit through openings in the ceiling on first floor levels. The radiant barrier is shown to reduce about 68 of the heat that is being radiated into the attic. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. This drain removes the excess water that a heating system will generate.

Then it moves along floor joists to any upper levels. So why put an hvac system up in the attic at all. Well mainly it s a way to save space. The trick to the installation of a gas furnace in an attic space is routing the condensate drain from the attic down through the core of the house to the basement.
