What Is an Air Handler and How It Heats & Cools Your Home ?
I’ll keep it simple: the air handler is your indoor unit—the box (usually in the attic or a closet) that pulls air in, cools or heats it, and pushes it back through your ducts.
In DFW we see two main installs:
Attic units in horizontal position with a condensate pan and float switch.
Closet units in vertical position with a return plenum beneath.
Airflow basics: return, coil, blower, supply
Air enters through the return, passes the filter into the evaporator coil, the blower moves it across the coil, and it exits through supply ducts to each room.
Heat strips: electric heating without gas (vs. heat pump)
Your handler can heat in two ways:
Electric heat strips (resistive heat): no gas involved—pure electric elements (“heat strips”) that warm the air.
With a heat pump: the outdoor unit reverses the refrigeration cycle to deliver heat; the strips become aux heat for very cold snaps.
When each system makes sense in DFW
If you don’t have gas service (or prefer to avoid gas), an air handler is a clean choice. If you want lower winter operating costs, a heat pump can help. If you already have affordable natural gas and want powerful heat, a gas furnace is efficient.
Efficiency, safety & operating costs
We guide you on SEER2, duct sizing, static pressure, and safety devices (float switch, proper drain routing) so you spend less on energy and avoid water damage.
