Dirty Flame Sensor? The 10-Minute DIY Fix That Saves $200+ on a Service Call
Your furnace's flame sensor is a small metal rod — usually about 3 inches long — that sits directly in the burner flame. Its job is simple but critical: confirm that gas flowing to the burner is actually igniting and burning. If the flame sensor doesn't detect flame, the control board shuts off the gas valve within seconds to prevent raw gas from filling your home. A dirty flame sensor is the second most common furnace repair call in Minnesota, right behind failed igniters — and it's the easiest DIY... Read more...
Heat Pump vs. Gas Furnace in Minnesota: A 2026 Cost and Performance Analysis
Minnesota homeowners have been hearing a lot about heat pumps lately — and for good reason.

Furnace Venting Explained: Chimney vs. PVC for Minnesota Homes
If you're building a new home in Minnesota or upgrading an existing furnace, understanding venting is essential. The type of venting determines where you can place the furnace, how exhaust exits, and which models work for your situation. Standard Efficiency Venting (80% AFUE) Standard 80% AFUE furnaces produce exhaust at 350–450°F that naturally drafts upward through metal flue pipe (Type B vent) or a masonry chimney. An inducer fan ensures consistent draft. The exhaust exits through the roof. Requirements Vertical Type B vent or lined masonry chimney Proper clearances from... Read more...
Ductwork Problems Costing You Money? How to Fix Leaky Ducts in Minnesota
Ductwork is the circulatory system of your HVAC. Your furnace can be the most efficient unit on the market — but if your ductwork is leaky, undersized, or poorly designed, you're throwing money away.

Signs Your Ductwork Needs Attention Rooms That Are Always Too Hot or Too Cold If certain rooms are consistently uncomfortable despite the furnace working properly, the ductwork serving those...

Furnace Igniter Replacement: The #1 DIY Furnace Repair Every Homeowner Should Know

Whole-House Humidifier Guide for Minnesota: Types, Sizing, and Installation
If you're building a new home or finishing a basement in Minnesota, you're going to need a whole-house humidifier. Minnesota's winter air is brutally dry — outdoor humidity regularly drops below 20% from November through March. When your furnace heats that already-dry air, indoor relative humidity can plummet to 15% or lower without supplementation. That's drier than the Sahara Desert. Low humidity causes cracked skin and lips, static electricity, dried-out wood furniture and flooring, increased cold and flu susceptibility, and higher perceived cold (dry air feels colder than humid air...

Furnace Condensate Drain: Clogs, Freezing, and Maintenance for Minnesota Homeowners
High-efficiency furnaces (90%+ AFUE) produce condensation as a normal part of their operation. This condensation — essentially water extracted from combustion exhaust gases — needs somewhere to go.

Understanding your furnace's condensate system takes five minutes and can prevent some of the most annoying and preventable furnace shutdowns Minnesota homeowners experience. Why High-Efficiency Furnaces Produce Water A standard 80%... Read more...
