Most homes have their HVAC system tucked away either in a furnace room in the basement or in a utility room or closet in the main living area. But some people find it beneficial to put the HVAC unit in their attic, even if they have a basement.
With an attic-mounted HVAC system, all the indoor components are installed in the attic, including the air handler or furnace, which contains the evaporator coils and fans used to heat or cool the house. The air is then distributed through ducts, which run through the attic. The condenser remains outside. Note this is different from a home heated by hot water boiling systems that have cooling systems in the attic.
Here are the pros and cons of attic HVAC systems.
Pros
- Space. This is the big benefit. Attics are frequently wasted space. By installing an attic HVAC system, you free up space in the living area of your home. Note that this is especially appealing in homes that do not have basements
- Potentially lower installation costs. Ductwork is labor-intensive and can be expensive. With the system in the attic, ducts have a shorter path to the living area. Less effort, less expense.
Cons
- Higher utility costs. The attic is an unconditioned space. It gets very hot in the summer and cold in the winter. So, it needs to work harder to cool in the warm months and heat in the cold months.
- Additionally, extreme temperatures can damage the equipment, leading to repair costs and shortened equipment life.
- Water damage. Your air conditioner also removes humidity. It produces moisture called condensate. The condensate drain must be monitored to make sure it does not overflow. If it overflows in the attic, the water can damage your attic insulation, drywall, and more. This can lead to thousands of dollars in repairs.
- You won’t hear warming signs. Noises such as grinding, rattling, and squealing are signs of trouble. But with your unit in the attic, you may not notice
