When your furnace quits at 20 below, you do not have time to wait. Northland Air carries common furnace parts on the truck (ignitors, flame sensors, pressure switches, blower motors), so most no-heat calls are one trip. We service every common gas and propane furnace brand and run 24/7 emergency dispatch through every Northland winter.
For replacements, we do a real heat-load calculation on your home, not a rule-of-thumb square-footage guess. That means a system sized to keep every room even, with the efficiency rating that actually pencils out for your annual gas bill. We walk you through 2-stage versus modulating, AFUE differences, and what each option costs to run year over year before you commit.

Warning Signs
Recognize Any of These Signs?
If any of these sound familiar in your home, it is time to bring in a licensed pro before a small issue becomes a major repair.
Yellow flame instead of steady blue
Incomplete combustion. Possible CO risk. Stop using the system, ventilate the area, and call us same-day.
Furnace cycles on and off every few minutes
Short cycling. Usually a dirty flame sensor, oversized equipment, or restricted airflow. Cuts furnace life in half if left alone.
High-pitched squealing or grinding from the furnace
Failing blower motor bearings, slipping belt, or worn-out inducer motor. Replace the part before it fails completely and shuts the system down.
Soot stains or rust on the cabinet
Sign of combustion problems, condensation issues, or a cracked heat exchanger. The cracked-heat-exchanger scenario is a CO risk and warrants immediate inspection.
Heating bill 20 percent or more higher than last winter
Efficiency loss from dirty burners, leaking ductwork, or a system approaching end of life. A tune-up plus heat-load calc shows what is driving the cost.

Service FAQs
Common Questions About This Service
Quick answers to the questions homeowners ask most about this specific service.
How long does a furnace install take?
Most straight replacements are done in a single day, often by mid-afternoon. Larger jobs with ductwork modifications or fuel-conversion work may run a second day, scheduled and quoted upfront.
What brands of furnaces do you install and service?
We service every major brand including Carrier, Trane, Lennox, Goodman, Amana, Rheem, Bryant, and York. For new installs we recommend models based on your home’s heat load and your priorities (upfront cost vs. lifetime efficiency).
My furnace clicks but will not light. What is happening?
Most often that is the ignitor (hot surface or spark) cycling without success. Common causes are a dirty flame sensor, weak ignitor, blocked condensate drain on high-efficiency models, or a pressure switch issue. Call us and we will diagnose on site, usually one trip.
Why does my furnace keep shutting off after a few minutes?
That short-cycling is often a dirty flame sensor, a clogged filter, an oversized furnace, or a blocked flue. A dirty flame sensor is the most common and cheapest fix, so we clean and test it rather than guess.
What does a furnace tune-up actually include?
We clean the burners and flame sensor, inspect the heat exchanger for cracks, test the ignitor and gas pressure, verify safe combustion and CO levels, and check airflow. It is a safety inspection as much as an efficiency one.
Is a cracked heat exchanger really that serious?
Yes. A cracked heat exchanger can leak carbon monoxide into your home, so it is a safety shutdown, not a keep-an-eye-on-it item. We show you exactly what we found and walk through your options.
