Should I Turn My Furnace Off Completely? No. Your furnace still runs the blower motor during cooling season. It helps circulate air throughout your home. Do not: Shut off furnace power Flip furnace breaker Close supply vents What Should I Do Before Cooling Season? 1. Replace the Air FilterYour furnace filter works year-round — including during AC season. 2. Check Humidity LevelsMinnesota winters are dry. Spring humidity rises quickly. Ideal indoor humidity: 30–50% If humidity climbs too fast, yo

Why Won’t My AC Turn On in Spring? Common causes: 1. Tripped Breaker Outdoor units share electrical circuits that may trip over winter. Check: Main panel AC disconnect box 2. Thermostat Still on Heat Sounds simple — but it happens constantly. Make sure: Mode is set to COOL Temperature is set below current room temp 3. Dirty Air Filter A clogged filter can restrict airflow and prevent startup. Replace filter before first cooling cycle. 4. Outdoor Unit Damage Minnesota winters bring: Snow buildup

When Is It Safe to Switch From Heat to Air Conditioning? For most Minnesota homeowners, the switch from furnace to air conditioning happens sometime between late March and early May. But the real answer depends on outdoor temperatures — not the calendar. You can safely switch to AC when: Daytime temps are consistently above 60°F Overnight temperatures stay above 40°F There’s no risk of hard freeze Running your AC when it’s too cold outside can damage the system. Air conditioners are designed to

If some rooms in your home feel like a sauna while others feel like an icebox, heater zoning may be the missing link. Zoning allows different areas of your home to be heated independently instead of relying on a single thermostat. In a zoned system, dampers inside the ductwork open and close based on demand from multiple thermostats. This means upstairs bedrooms, basements, additions, or sunrooms can each get the heat they actually need. Zoning matters most in: Multi-level homes Houses with addi

Heating bills don’t usually spike because of one big mistake — they creep up due to dozens of small ones. A dirty air filter can increase energy use by forcing your furnace to work harder. Drafty doors and windows leak warm air nonstop, especially during windy Minnesota nights. Closing vents in unused rooms may seem smart, but it often disrupts airflow and lowers efficiency. Even thermostat habits matter. Constantly adjusting the temperature or cranking the heat to recover from big setbacks uses

When COVID, flu, and respiratory illnesses circulate, people spend more time indoors — exactly when homes are sealed tight for winter. That combination makes indoor air quality more important than ever. Viruses and bacteria spread more easily in dry, stagnant air. Low humidity can dry out nasal passages, weakening your body’s natural defenses. At the same time, limited ventilation allows airborne particles to linger longer. HVAC systems play a major role here. Upgraded filtration, balanced humid

Gas furnaces are reliable workhorses in Minnesota winters, but safety should never be assumed. Every homeowner should be familiar with a few basic checks that help prevent dangerous situations. Start with carbon monoxide awareness. If you don’t already have CO detectors on every level of your home, winter is the time to add them. A cracked heat exchanger or blocked vent can allow dangerous gases to build up without warning. Next, take a look at your exhaust and intake pipes outside. Snow, ice, o

​Change filters? DIY. Adjust a thermostat? DIY. Replace a heat exchanger or test a gas valve? That’s a pro job. DIY saves money — but only if you stay safe. Don’t risk carbon monoxide leaks or electrical hazards. When in doubt, YouTube less, call more.

That blinking red light isn’t Morse code — it’s a diagnostic. Most furnaces have a panel or sticker explaining what each blink pattern means. Common codes point to ignition failure, dirty filters, or limit switch trips. Look it up in your manual or online. But if it keeps blinking after a reset, call in the pros.

​Once a year — that’s the magic number. Every furnace or heat pump needs an annual checkup to stay efficient and safe. Fall is ideal, but if you missed it, winter is still better than never. Maintenance includes cleaning burners, testing safety controls, inspecting heat exchangers, and checking airflow. It’s cheaper than a mid-storm emergency call.
