Upgrade your MRCOOL Universal 2nd Gen central ducted system with a factory-matched Electric Heat (Emergency/Aux) Kit. This add-on installs in the air handler and provides an extra boost of electric heat when outdoor temperatures drop well below your heat pump’s rated heating range—helping maintain comfort during cold snaps.
Available sizes: 5kW • 8kW • 10kW • 15kW • 20kW Includes: model-specific heat strip assembly with integrated circuit breaker
Why add a heat kit?
Cold-weather backup: Heat pumps naturally lose heating capacity as outdoor temps fall. The heat kit supplies aux/emergency heat to cover those lows.
Comfort & reliability: Smooth transitions during defrost and extreme weather.
Factory-matched fit: Designed for MRCOOL Universal 2nd Gen air handlers for correct airflow, safeties, and wiring.
Circuit breaker included for the kit (model-specific)
