The GE GRHS15XAHW delivers 15,000 BTU of rooftop cooling and reverse-cycle heat pump heating in a single unit. Running on R32 refrigerant -- a next-generation refrigerant with 70% lower global warming potential than R410A -- it gives RV owners year-round climate control without burning propane. Heat pump operation is effective down to 25F ambient, making it a practical propane saver for shoulder-season camping. This unit is a direct replacement for the GE ARH15AACW cool-only model. An upgrade kit is required for installation when replacing an older unit.
Most RV rooftop ACs only cool. The GRHS15XAHW adds a reverse-cycle heat pump, so the same unit that keeps your rig comfortable in July can take the edge off a 35F fall morning without firing your furnace. That means less propane consumption, less noise from the furnace blower, and fewer tank fill-ups on extended trips.
The R32 refrigerant is a modern single-component refrigerant with high energy efficiency and a significantly lower environmental footprint than the R410A used in most RV ACs currently in the field. R32 also has zero ozone depletion potential (ODP = 0).
Provides electric heat when ambient temps are 25F and above -- no propane required for shoulder-season comfort.
70% lower global warming potential than R410A. Zero ozone depletion. Efficient single-component charge.
Coil coatings and housing materials resist salt air and road chemicals for long-term reliability in all climates.
Noise-reducing components and balanced fan assembly minimize cabin intrusion during sleep or stationary work.
When outside temps are between 25F and 65F, the heat pump is more efficient than a propane furnace for maintaining comfortable interior temps. Full-timers and snowbird travelers report meaningful reductions in propane consumption by relying on the heat pump during morning warm-ups and cool evenings.
The GRHS15XAHW is the factory replacement and upgrade path for the GE ARH15AACW 15,000 BTU cool-only rooftop unit. Because the heat pump model uses a different control architecture, an upgrade kit is required when retrofitting into an RV that originally had the ARH15AACW. Verify compatibility with your interior control box and thermostat before ordering.
This unit is NOT a plug-and-play swap into all existing GE rooftop AC cutouts without additional components. If you are replacing an ARH15AACW or other older GE rooftop unit, a separate upgrade/conversion kit is required to connect the heat pump controls to your interior unit. Confirm kit availability and part number before purchasing this rooftop assembly alone.
R32 is a hydrofluorocarbon (HFC) refrigerant classified as A2L (mildly flammable) by ASHRAE. In an intact, properly installed rooftop AC system, the charge is sealed and presents no practical hazard during normal operation. However, any refrigerant service, leak repair, or recharge must be performed by an EPA Section 608 certified technician familiar with A2L refrigerants. Do not attempt to service the refrigerant circuit yourself.
