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.

Circle Pines started in 1946 as a cooperative village beside Golden Lake, and the city still owns the company that pipes natural gas to its houses, Centennial Utilities.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Circle Pines and across Anoka 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.
Electricity comes from Connexus Energy in most of Circle Pines and from Xcel Energy in parts of the west and south sides, so it depends on your address.

Book in Circle PinesThe Golden Lake Development Association, renamed the Circle Pines Development Association later in 1946, planned a 1,203-acre cooperative village in which every resident bought at least one share. Its first ten houses were Cemesto homes, prefabricated in Texas with slab floors and cement-sheet walls, and they suited Minnesota winters so poorly that the design was dropped. Only 84 houses were finished by 1949, and the co-op model faded after one of its founders died in 1950, the year the village incorporated.
The real build-out followed: about 2,800 residents by 1960 and 3,900 by 1970, then another round of building in the 1980s, and the population has barely moved since 1990. So nearly every job here is on an existing house, often in a furnace room that has held three or four furnaces. The co-op also left the city its own gas company. Centennial Utilities bills monthly, answers gas emergencies with its own staff, and treats the piping after the meter, including buried lines to a garage, as the homeowner's.
Circle Pines' older houses often keep a water heater, and sometimes an 80% furnace, on a masonry chimney that is now 60 or 70 years old. Winter is when that matters: the furnace runs for hours with the windows shut, and a flue narrowed by fallen mortar or a bird's nest can spill exhaust into the basement instead of sending it up. State law calls for a working CO alarm within 10 feet of each sleeping room. If one sounds, get everyone outside and call 911, then have the venting checked before the furnace runs again.
The city describes itself as dotted with oaks and elms, and those trees load condensers every spring. Elm seeds drift into the fins in May and June, oak catkins and leaves follow, and a coil packed with them can't shed heat. On the first 90-degree afternoon the compressor runs hot, trips on its overload and restarts, or a tired capacitor finally quits. Rinsing the coil after the seed drop, with the power off, means the system doesn't start summer already choked.
Gas rebates work differently here because the gas company is Centennial Utilities, owned by the city. It offers customers a discounted home energy audit by a state-certified auditor; we found no furnace rebate on its website, so ask before counting on one. Electric programs depend on the address. Connexus Energy members can claim heat pump rebates for ducted, ductless and geothermal systems plus a central AC rebate, while homes on the Xcel Energy side can use Xcel's AC rebates and its Trade Partner Network heat pump rebates. Ask whether a rebate needs a registered contractor.
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.

Centennial, the city's gas utility, handles the supply side up to and including the meter, and it responds to gas odors and leaks. If you smell gas, leave first, then call Centennial at 763-784-6751 on weekdays or, after hours, Anoka County Dispatch at 763-427-1212 or 911 and ask for Centennial Utilities. Past the meter, the house piping, furnace and venting are yours, and that's the equipment we repair.
Usually out a side wall. The co-op-era plan put fronts on footpaths, now city trails, and garages on the street, so both the front and the back of these houses see foot traffic. PVC intake and exhaust need the manufacturer's clearances from doors, windows, the gas meter and walkways, and a plume of steam drifting over a public trail annoys walkers all winter. We mark the route and the termination during the quote.
You do. Centennial Utilities treats underground piping after the meter, such as a line to a detached garage or a gas grill, as the owner's responsibility. Its customer guide warns that these lines can corrode, that steel lines need cathodic protection and that copper can decay too. If you smell gas outdoors near one, call Centennial. An old buried steel line is worth testing before a garage heater is added to it.
Yes, over time rather than on the next bill. Centennial Utilities sets the equal payment from your past usage and expected gas prices, then reviews it twice during the heating season and again about six months later. A 96–98% furnace replacing an old 80% model buys less gas for the same heat, and as that lower usage becomes your history, the payment follows. Keep old bills handy to compare winters.
