Why Is My Heat Pump Blowing Cold Air in Winter?
Heat pump air feels cool next to a furnace even when it works. How to tell normal from a fault: defrost, a thermostat setting, low charge or no aux heat.

When a Roseville AC gives out, we can put a cold-climate heat pump in its place and pair it with your gas furnace, for $7,500–$14,500 installed, flat-rate and in writing. Your gas and your electricity both come from Xcel, so the switchover point is figured from one company's rates.
Roseville's 1950s ramblers are about the easiest houses in the metro to put on a heat pump. They're compact, one story over a full basement, with trunk-and-branch ducts that reach every room in short runs. A ducted heat pump in the old condenser's spot, with the gas furnace kept as backup, heats most of the house through October, November and March, and the furnace carries the deep-cold weeks.
The catch is what earlier upgrades left behind. Central air arrived late in many of these houses, and the coil on top of the furnace may be undersized or mismatched, so we size the new system from a load calculation instead of copying the old tonnage. Leaky trunk joints in unfinished parts of the basement are worth sealing while we're there. Xcel's heat pump rebates require going through its Trade Partner Network for most equipment, so ask whether the model you're considering needs a registered contractor.

An installed heat pump from us runs about $7,500–$14,500 in Roseville, with a written flat-rate quote. Same prices in Roseville as in every town we serve. See the heat pump cost guide. For what drives a quote locally, see HVAC cost in Roseville.
Xcel Energy supplies Roseville's gas and electricity, so a furnace, AC or heat pump project runs through one utility's programs. For the dual-fuel setups that suit many Roseville ramblers, Xcel lists rebates for standard and cold-climate air-source heat pumps and a bonus when insulation work comes before the heat pump. Its heat pump rebates are paid through Trade Partner Network contractors, so ask about that before you sign. Gas furnace rebates are a separate Xcel program with their own requirements. Rebate programs change every year, so check the utility's current terms before you buy.

Possibly, but most owners keep the furnace. A small rambler with good attic insulation has a modest heat load, and a cold-climate heat pump with electric backup strips can carry it. On a sub-zero night, though, those strips are expensive to run, and many 1950s houses still have thin wall insulation. Dual fuel with the gas furnace you already own is usually the cheaper route here.
Usually close to where the old AC sat, since the line set and wiring already run there, but higher. A heat pump works all winter and sheds water during defrost, so it sits on a stand above typical snow depth, out from under the roof edge where icicles fall, and away from a walk where meltwater could refreeze. A spot sheltered from the prevailing wind by the house helps too.
