TOSOT mini-split heat pump — rowhome roof

The problem

A Philadelphia rowhome that needed heating and cooling without ductwork.

What we did

Installed a TOSOT inverter mini-split heat pump with the outdoor unit set on a roof stand and the line set routed to the indoor head, then commissioned in both modes.

Questions homeowners ask about jobs like this

Is a mini-split heat pump enough for winter?
For a rowhome, yes — inverter mini-splits keep full output well below freezing, and the same unit cools in summer.

What does it cost?
A complete ductless heat pump system runs $10,000–$14,000 installed. ENERGY STAR models qualify for PECO and EAP rebates, which we file.
