No Guesswork — Every Pro Direct Air Handler Covered

Walk into any big-box store and ask which heat strip fits your specific air handler model — you'll get a blank stare. We vetted this kit against every Pro Direct unit MRCOOL makes, from the HAH14018 to the HAH14060. One part number covers all seven. No cross-referencing, no return trips, no wondering if you bought the right thing. That's the difference between a curated parts list and a warehouse shelf.

Emergency Heat That Doesn't Quit on Cold Nights

Emergency Heat That Doesn't Quit on Cold Nights

When your heat pump can't keep up in extreme cold, the PHK05H kicks in with 5 kilowatts of electric resistance heat. It's not your primary heat source — it's your safety net. The integrated circuit breaker means you don't need to wire in a separate breaker, simplifying installation and reducing potential failure points. UL listed for safety, 240V for reliable performance.
