No heat on a sub-zero St. Paul night? We've served St. Paul since 1988, with crews staged a short run north on Highway 52, so most no-heat calls in 55101, 55102, 55105, 55106, 55116, and 55118 are out the door same day. Firm written quote first, no upsell, family-owned since 1988.
Fill this out and a real person calls you back within an hour, not a call center.
We've served St. Paul since 1988, with crews staged a short run north on Highway 52 and quick access via I-35E, I-94, Highway 52, and West 7th Street, so most no-heat calls are a short run even in January. We're a licensed Minnesota mechanical contractor (MN #MB739673), which means our techs already know the local code and the inspection process. Whether you're in a 1920s bungalow in Macalester-Groveland, a larger home in Highland Park, or a West Side place still running boiler heat, we know the housing stock and the way a Minnesota cold snap finds the weak point in an old system.
We've been repairing gas furnaces, high-efficiency systems, and heat pumps for St. Paul families since 1988. The approach hasn't changed: diagnose the real problem, explain the fix in plain English, write a firm quote, and only then do the work. Safety comes first on heating calls, if we find a cracked heat exchanger or a carbon monoxide risk, we'll tell you straight. And if the repair isn't worth it, you'll get a FREE second opinion before anyone talks replacement.
Furnace won't fire, often an igniter, flame sensor, control board, or thermostat issue. The #1 winter call.
Blower runs but the air is cold, usually a failed igniter, dirty flame sensor, or a lockout from a safety switch.
Furnace turns on and off every few minutes, often a clogged filter, overheating limit switch, or flame-sensor problem.
Vents barely pushing air, a failing blower motor, bad capacitor, or a duct restriction starving the system.
A loud boom when the burners light usually means delayed ignition, gas building up before it catches. Get it looked at fast.
Rotten-egg odor near the furnace is a safety issue. Leave the house, call your gas utility or 911, then call us.
A healthy burner flame is steady and blue. Yellow or flickering can signal a combustion problem and carbon monoxide risk.
Heating bill jumping with no weather change? The furnace is losing efficiency, sometimes a tune-up, sometimes a real repair.

Most furnace repairs in St. Paul fall in the $150–$650 range, a flame sensor might run $150–$250, a hot-surface igniter $200–$350, a blower motor $450–$850. Bigger jobs (control board, inducer motor, gas valve) can run higher, and we'll always walk you through repair-vs-replace math before you commit, especially on the older systems common in Highland Park and Macalester-Groveland.
