How Often to Change a Furnace Filter in Minnesota
Check a 1-inch furnace filter monthly and change it when dirty, at least every 3 months; 4-inch media runs 6-12 months. Pets, smoke and fan-on shorten it.

Central Minnesota Heating and Cooling repairs and replaces furnaces, ACs, heat pumps and boilers in Lino Lakes (Anoka County), about 15 miles from downtown Minneapolis.
Lino Lakes is built around the Rice Creek chain of lakes, from Reshanau to George Watch, and most of its houses went up in the 1990s and 2000s between Interstates 35W and 35E.

Book in Lino LakesLino Lakes became a village in 1955, when Centerville Township voted to incorporate so neighbors couldn't keep annexing its land, and for decades it stayed mostly open country around the lakes. The population went from about 7,800 in 1990 to 11,800 in 2000 and 20,200 in 2010, so most houses date from those two decades: two-stories, walkouts and townhomes, many backing onto wetlands, the Rice Creek chain or preserved open space.
Older homes are scattered among them: a few farmhouses, 1960s and 70s ramblers on larger lots, and lake homes of mixed ages, some of which may heat with propane where gas service never reached. The newer houses are built tight, with condensing furnaces, air exchangers and finished walkout lower levels where the mechanical room hides behind a door off the family room. Leaving a clear path to that room matters, because a furnace and coil have to come out through the finished space someday.
Wetlands and lakes give the wind a long, open run at Lino Lakes houses that back onto them, and snow drifts against vents and heat pumps on that side. Walkout lower levels facing the water lose heat through big glass doors. The newest homes are tight enough that indoor humidity builds in winter if the air exchanger is off, and frost on the inside of the windows is the tell.
Houses backing onto marsh and open water see heavy humidity from June through August, and lake-facing walls of glass add afternoon sun to the upstairs of two-stories. Townhome condensers crowd shared side yards. Builder air conditioners from the 1990s are old enough now that many have been replaced once, and the ones that haven't likely still run on R-22, which turns a refrigerant leak into a replacement conversation.
Lino Lakes splits both ways. For electricity, Connexus Energy members have rebates on air-source, ductless and ground-source heat pumps and central air, plus the PowerNap smart thermostat program and a reduced-rate program for heat pumps paired with a furnace, while Xcel Energy customers use its Trade Partner Network rebates; ask whether the rebate needs a registered contractor. For gas, Xcel Energy runs heating equipment rebates for high-efficiency furnaces, and Centennial Utilities customers should ask that utility directly.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: heat pump rebates, what happened to the federal credits.

Lake air is humid, the lower level is partly underground and cooler, and the air conditioner rarely runs long enough down there because the thermostat is upstairs. Cool, still air holds that moisture. A whole-home dehumidifier tied into the ductwork, a separate zone for the walkout, or a variable-speed blower set up to dehumidify all help. When the musty smell fades, the humidity is under control.
The gas utility depends on the neighborhood. Xcel Energy supplies gas in Lino Lakes, and Centennial Utilities, the gas utility run by the City of Circle Pines, serves some areas. Electricity is split too, between Connexus Energy and Xcel Energy. Furnace and heat pump rebates follow the utility named on each bill, so check both before we quote.
Almost certainly, if it's original. The rating plate on the side of the outdoor unit lists the refrigerant. R-22 production ended in 2020, so recharging uses reclaimed refrigerant at a steep price, and an R-22 system can't simply be topped off with a newer refrigerant. A replacement needs a new matched indoor coil, and we check whether the line set can be reused. If it still cools and doesn't leak, it can keep running.
Maybe not. Houses built here in the 1990s and 2000s are tight, and many hold enough moisture from cooking, showers and people to stay comfortable. Watch the windows: frost or water on the inside glass means the house is already too humid for the outdoor temperature. If the air feels dry and the windows stay clear, a humidifier set to about 30 percent, and lower in deep cold, can help.
