Saint Paul homeowners get cold-climate heat pumps from us at $7,500–$14,500 installed, quoted in writing after a load calculation. Xcel Energy supplies both gas and electricity here, so on a dual-fuel system we set the furnace to take over where gas becomes the cheaper heat for your house.
Heat pump work in Saint Paul splits by what's in the basement. The Highland Park and East Side ramblers and story-and-a-half houses, plus the converted-gravity foursquares in Macalester-Groveland, Hamline-Midway and Como, have ducts, and those houses are candidates for a ducted heat pump paired with the gas furnace. The old round supply ducts usually have capacity to spare; the returns and the filter rack are what we end up rebuilding.
The radiator houses on Summit Hill and Cathedral Hill are a different job. No ducts means ductless heads or a small-duct high-velocity system run through closets and the attic, with the boiler kept for deep cold. Xcel is the electric utility everywhere in the city.

Our $7,500–$14,500 installed price comes as a written flat-rate quote, with a 2-year labor warranty on top of the manufacturer's parts warranty. A Highland Park or East Side rambler with ample round supply ducts costs less than a house where the returns and filter rack must be rebuilt first. See the heat pump cost guide. For what drives a quote locally, see HVAC cost in Saint Paul.
Ductless and mini-split heat pumps used to cool radiator homes have their own Xcel rebates, and some Xcel rebates require a registered contractor, so check that before choosing equipment. Rebate programs change every year, so check the utility's current terms before you buy.

Not directly. Steam radiators need steam, and an air-source heat pump makes warm air or low-temperature water. What works is adding heat pump capacity beside the boiler: ductless heads in the rooms you use most, which cool in summer and carry spring and fall, with the steam boiler firing on the coldest days. That cuts the hours the boiler runs without touching the radiators.
Yes, and it's simpler than it sounds, because each unit already has its own furnace, ducts and thermostat. Each side gets its own outdoor unit and its own dual-fuel setup. The harder parts are finding two outdoor spots on a city lot that stay clear of drifting snow and each other's windows, and making sure each unit's electrical service has room for a new 240-volt circuit.
