[RESOLVED!] What Is Attic Air Handler?

An air handler can be an indoor component of your heat pumps system, depending on your house’s design. When properly matched with the capacity and SEER (Seasonal Energy Efficiency Ratio) of your heat pump, the air handler is designed to efficiently circulate conditioned air through your home’s duct work. The season determines whether the air being circulated is cool or warm. According to the Air Conditioning, Heating and Refrigeration Institute (AHRI), mismatched systems are at least 30 percent less efficient than matched systems 😉1 Homeowners should keep this efficiency loss in mind when they are considering replacing only the outdoor unit portion of their split system 😁 [1]
It can feel like professional HVAC contractors know everything. We trust them to do our jobs correctly and on-time. But that does not mean they don’t argue over some issues in the process. Contractors can’t seem to reach an agreement on attic HVAC systems. Is it had cost-effective? They are bad for your energy consumption. It really makes a big difference in energy use. Today, we will investigate this controversial subject and give you a point/counterpoint breakdown of attic HVAC units—and tell you how to manage your attic HVAC system so it can perform its best. Thank you to Lia Rapp (from Winnipeg, Canada) for this tip. [2]

Attic is the most complained about area. Air conditioners is that they don’t really make sense. Attics are, for the most part, unconditioned, meaning a leak here could significantly reduce your home’s overall efficiency. To avoid this, HVAC contractors must take care to properly seal and insulate ducts—something not all of them do to the same degree of precision. But even if the ducts are installed to a tee, there’s still the possibility that leaks will develop. Ductwork naturally expands and contracts with your home’s vacillating temperatures, and in time that can loosen duct seals. The risk of leaking is extremely real.

Cooler is better. Garages don’t have as much of a thermal load as an attic. Garages may be cooler than attics, but this is not necessarily a bad thing.5 Colder temperatures can mean lower relative humidity. The air in an attic and garage comes from the same place…outside. The dew point is the same, but relative humidity is higher. It gets worse…wait for it….in a hot attic the box that makes air cold is actually warmer. In a garage, it is much different. As well as the supply plenums, air handlers can be colder than their equipment. So stuff sweats more…way more. Moving air handlers into garages actually made the equipment and ductwork more moist. We are grateful to Ned Espinosa who pointed this out. [4]
