MRCOOL's DIY Heat Pump Targets Low-Income Home Heating

A new DIY heat pump eliminates outdoor unit installation costs and space needs for low-income households.

MRCOOL’s Monoblock MTHP heat pump plugs directly into standard 115-volt household outlets without requiring an outdoor condenser unit—a key barrier for low-income households that often lack space or funds for traditional HVAC installations. It delivers 9,000 Btu/h heating and 10,000 Btu/h cooling, operates within 5°F to 113°F temperatures, and costs $1,370–$1,550. The unit requires two wall openings for air intake/exhaust and one for drainage but avoids professional installation due to its sealed refrigerant circuit. Its August 2026 release date marks the earliest availability for retailers.

This design simplifies heating access by cutting the need for expensive outdoor units and specialized technicians. For low-income households, this reduces installation complexity and upfront costs—eliminating potential barriers like outdoor space or technician fees that often make heat pumps unaffordable. However, the unit’s efficiency ratings (15 SEER2 cooling, 7.5 HSPF2 heating) are lower than ductless mini-splits, and it’s not suitable for areas with winter temperatures below 5°F.

For low-income households in temperate climates, this model could lower heating costs by avoiding outdoor unit installation expenses. But its two-person installation requirement and cold-climate limitations mean it won’t solve heating access for all. What to watch: whether local building codes adapt to this DIY approach and whether the price point remains affordable as production scales. The source notes the unit’s efficiency lags behind conventional ductless systems—a critical caveat for households prioritizing energy savings.
