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.

Grant stayed a township until 1996 and became a city mainly to protect its rural character, so houses here sit on acreage with private wells and septic, and zoning since 1976 has held new lots to an average of 10 acres.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Grant and across Washington County. Every visit starts with a $79 trip charge and a written price before any work, and the $79 is waived when you go ahead with the repair.
Whether Xcel Energy's gas reaches your property depends on your address, while Xcel supplies the electricity to all of Grant.

Book in GrantGrant was organized in 1858 as Greenfield Township, renamed for Ulysses S. Grant in 1864, and gave up its western third to Lincoln Township in 1918, land that later became Mahtomedi, Willernie, Birchwood and Pine Springs. What remained was farm country. About 13 percent of today's homes were built before 1940, farmhouses and the historic houses the city lists along Manning Avenue among them, and houses that old often carry additions from several eras and a chimney that has served more than one fuel.
Building picked up in the 1960s and peaked in the 1970s, which produced a quarter of the city's homes, mostly on lots under five acres. In 1968 the town raised its minimum lot to 2.5 acres over septic concerns, and from 1976 it followed a Metropolitan Council directive of a 10-acre average and a 5-acre minimum, so later homes sit on larger parcels, many with barns or shops. The city's 2040 plan counted White Oaks Savanna on the east edge and The Gateway near the Mahtomedi school campus as the first new neighborhoods planned in nearly three decades.
Grant's open, rolling land gives the wind room to drift snow across long driveways and against the side of the house where furnace pipes and heat pumps sit. On propane, order a fill before a forecast cold snap rather than during one, and keep the drive plowed wide enough for the truck. Pre-1940 farmhouses lose heat through old walls and windows, and their far rooms fall behind first. Have the unit heaters in shops and barns looked at in October, before anyone needs them.
Condensers on Grant properties sit near pastures, gardens and tree lines, and pollen, seed and dust coat their coils faster than in town, so a spring rinse pays off. Farmhouses built long before central air often have upstairs bedrooms that never got a supply duct, and a ductless head is usually simpler than cutting in new runs. In the 1970s homes, any air conditioner still running on R-22 is on borrowed time, since a leak there almost always means replacement.
Because Xcel Energy is Grant's electric utility, its heat pump rebates, Residential Cooling Rebates, Saver's Switch and AC Rewards are open to every household, though the heat pump money flows through Xcel's Trade Partner Network, so check the installer requirement first. Where a home has Xcel gas, a high-efficiency furnace can add Xcel's heating equipment rebate. A propane home has no gas utility program, which makes the heat pump rebates the main ones to chase, and if Xcel's gas line reaches your road, ask about its Make the Switch to Natural Gas program.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

Usually, if the furnace stays as backup. Paired that way, the heat pump runs from spring into early winter and on mild January days, and the propane furnace takes the coldest stretches. Since a gallon of propane typically buys less heat for the money than natural gas does, those shifted hours are worth more in Grant than in town. Xcel also offers a reduced rate for homes that heat mainly with a heat pump; ask whether yours would qualify.
A vented unit heater hung from the ceiling suits most shops, burning propane or Xcel natural gas where it reaches, and a high-ceiling building can use an infrared tube heater instead. For scale, HomeGuide's national cost figures list $500–$1,400 for an installed propane garage heater and $400–$800 for infrared. A barn with animals needs its ventilation planned along with the heat, and any fuel-burning heater should have a CO alarm nearby.
Start with the fuel: natural gas or propane, and if propane, whether the tank is owned or leased. Then look at the furnace's age and venting, since an 80% model may share a chimney with the water heater, and read the refrigerant type off the AC's rating plate. Ask for service records and confirm there are CO alarms near the bedrooms. A furnace tune-up, from $129, before closing gives you a clear picture.
It will, with the right setup. A gas or propane furnace needs electricity for its inducer, igniter, controls and blower, and on a private well the pump needs power too. A generator sized for those loads, connected through a transfer switch or interlock that an electrician installs, will run them. Never backfeed through an outlet, and keep a portable generator outside, well away from windows and vents.
