With the Coleman Mach 15 HP2 High-Performance Air Conditioner with Heat Pump you get an economical, electric source of heat and a high-performance air conditioner in one sleek unit. The HP2 cools exceedingly well with a powerful 15, 000 BTU nominal cooling capacity. When a chill is in the air, a special reversing valve enables the cooling system to convert to a heating system. In fact, the HP2 puts 2-1/2 times more heat into your RV than an electric heat strip. The Mach 15 is equipped with a 1/3 HP fan motor, the largest used in an RV A/C, delivering cool air at an incredible 320 CFM. The Mach 15 streamlined shape enhances the airflow and cooling efficiency. All copper tubing and gas-flux brazed joints ensure long life and dependability. Large evaporator and condenser coils with raised lance fins enhance the system's ability to dissipate heat. The updated Mach 15 models feature a new textured shroud that blends cleanly with RV exteriors and resists UV fading. Note: This is the rooftop AC / Heat Pump unit only.
