Are there air conditioning coils in the attic.

Last week s blog post about inspecting air conditioners was all about traditional air conditioners with an evaporator coil sitting on top of a furnace in a basement. Typically this indoor unit gets placed in a cabinet or closet somewhere inside. An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. Sometimes in the attic.

The outside equipment is a compressor to force the refrigerant through the system and a condenser coil. With spray foam it might not get enough combustion air. The evaporator coil is the part of your ac system that actually cools the air before it is blown into your home. Got an 80 furnace in your attic.

The length to install an air conditioner coil will depend on the complexity of the job. There should be a removable access panel on the air handler that exposes the evaporator coil. The dehumidifier is preferred since your air conditioner will only dehumidify the attic while the system is running. If it s a simple swap and replace it can take up to three hours.

Most homeowners never actually see the evaporator coil because it is covered by a metal case that is usually in an indoor closet or attic. The inside equipment is usually placed in the basement a closet inside the house a closet in the garage. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. If all else fails you can install a dehumidifier in the attic or run some air conditioning ducts up there.

So why put an hvac system up in the attic at all. Adding ac to the attic will also put the space under positive pressure possibly forcing attic air into your living space. Put it in an attic full of blown insulation and you re forcing. However if it s hard to access the attic and more sheet metal and drain line work is required to fit the new coil it could take up to eight hours to perform.

Well mainly it s a way to save space. Some times the equipment is placed in a crawl space if there is not basement. The evaporator coil of a split system a c is located inside the air handler which is typically found in the utility closet garage basement or attic.
