Switching From Propane to a Heat Pump in Rural Minnesota
Adding a heat pump to a propane-heated Minnesota home: keep the furnace as backup, compare gallons to kilowatt-hours, and ask your co-op the right questions.

In South St. Paul, a heat pump installed by us costs about $7,500–$14,500, with the price in writing before work starts. In pre-1940 houses above the bluff the harder question is the ductwork, which is why many of these jobs end up ductless instead.
Most South St. Paul housing predates 1960, and that shapes what a heat pump install looks like. In the 1950s houses, a ducted heat pump is straightforward: the coil goes on the furnace, the outdoor unit goes beside the foundation and the gas furnace stays as backup. We check the return side first, since these ducts were sized for heat.
Above the bluff, west of Concord Street, many pre-1940 houses started on gravity heat and were converted to forced air, and some still have hot-water or steam boilers. Ducts there are often cramped, and a heat pump can't be asked to push enough air through them. For those houses we price both ways: new duct runs or a ductless system. Electricity is Xcel Energy citywide, but gas is either Xcel or CenterPoint, so check your bill first. CenterPoint's ducted heat pump rebate applies only when paired with a gas furnace, which suits a dual-fuel setup.

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 1950s house with heat-sized returns takes a ducted unit, but a pre-1940 bluff house with no usable ducts moves the price toward ductless. See the heat pump cost guide.
Xcel's furnace rebates point you to a participating contractor, and heat pump rebates from Xcel go through its Trade Partner Network. Rebate programs change every year, so check the utility's current terms before you buy.

Sometimes, depending on the ducts. Houses converted from gravity heat often have large, oddly routed trunks that may or may not carry enough air for a heat pump. We inspect them and measure airflow before quoting. If the ducts can't be corrected at reasonable cost, a ductless heat pump avoids the problem and can heat the main living areas.
Beside the foundation, usually near where the old AC sat, on a stand above typical snow depth and clear of roof drip and a neighbor's bedroom window. Defrost water has to drain away from the house, not onto a walk where it refreezes. We pick the spot at the site visit and show it on the written quote.
