Why Is My Heat Pump Blowing Cold Air in Winter?
Heat pump air feels cool next to a furnace even while working. Defrost, settings, low charge or failed backup: how to tell, and when to call 612-429-3465.

Lake Elmo heat pump installs cost $7,500–$14,500, flat-rate in writing, and the backup, gas, propane or electric, depends on your address. Gas is not available at every address here, so the first question is what backs the heat pump up on the coldest nights: a gas furnace, propane, or electric resistance.
Lake Elmo's housing runs from manufactured homes to new two-stage systems, and the heat pump plan changes with each. Homes on large rural lots, beyond the gas mains, often heat with propane. Pairing a cold-climate heat pump with a propane furnace is a dual-fuel setup that cuts propane use in the shoulder seasons. Older homes around the Old Village and Tablyn Park are different, with older furnaces and chimneys that we inspect before adding anything.
The sewered neighborhoods built near I-94 since 2010, such as Discover Crossing, are tight, with condensing furnaces and air exchangers. Their heating loads are small, so the main risk is oversizing, and we run a Manual J. In the small part of the city on CenterPoint gas, its ducted heat pump rebate applies when the unit is paired with a gas furnace.

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. The price depends on what backs up the heat pump, whether a gas furnace, propane or electric resistance, and homes beyond the gas mains weigh that choice. See the heat pump cost guide.
Xcel pays the heat pump rebates through Trade Partner Network contractors, so check that requirement before signing. Most of the city uses Xcel's heating equipment rebates, while CenterPoint Energy's small area gets CenterPoint's furnace rebates, which let you choose your dealer, plus its ducted heat pump rebate for dual-fuel systems. Rebate programs change every year, so check the utility's current terms before you buy.

Often, yes. A cold-climate heat pump can take over in mild weather and keep the propane furnace for the coldest days. Propane is usually the costlier fuel, so every hour the heat pump handles saves tank fills. We compare your propane price against Xcel's electric rate before recommending it, and keep the furnace as backup.
With a Manual J load calculation rather than a rule of thumb. Tight houses with air exchangers lose little heat, and an oversized heat pump short cycles and dehumidifies poorly. We also check how the unit and the air exchanger will work together, since both affect indoor humidity, and we put the sizing in the written quote.
