Furnace Repair in Shoreview, MN
Shoreview furnace repair begins with a $79 trip charge; approve the repair and we waive it, and the flat-rate price is in writing before any work. We take calls 7am–9pm, seven days. After a storm off Turtle Lake or Lake Owasso, a drifted PVC intake is one of the first things we check.
Furnace repair calls in Shoreview homes
Most Shoreview furnace calls land in houses built between 1960 and 1990, where the furnace in the basement or utility room is the second or third one on that spot. Many are now high-efficiency models from the 1990s and 2000s, and their failures follow a pattern: clogged or cracked condensate traps, pressure switches that trip when the drain backs up, inducer motors with worn bearings and flame sensors coated after years of running. Older houses on the north side that still vent an 80% furnace into a chimney add draft and flue problems to that list.
The lakes bring a winter pattern of their own. On houses facing open ice, snow drifts over side-wall intakes, and a furnace that ran fine all day locks out at 2 a.m. with a pressure switch code. In townhomes where the furnace shares a small room with the water heater, access and combustion air become part of the diagnosis.

Furnace repair in Shoreview: questions
Is it safe to keep repairing the chimney-vented furnace in our older north-side Shoreview house?
It can be, if the venting checks out. We run the furnace and water heater together and confirm the flue gas goes up the chimney, look for spillage at the draft hood on top of the water heater, and check the flue pipe for rust and gaps. If the chimney won't draft properly or the furnace is near the end of its life, we'll say so and price a liner or a replacement in writing.
We're away for part of the winter. How do we keep our Shoreview furnace from quitting while we're gone?
Start with a fall tune-up so worn parts get caught early, put in a fresh filter, and leave the thermostat no lower than 55°F. A Wi-Fi thermostat that sends a low-temperature alert is worth the money. Ask a neighbor to look at the house after big storms, because on a lake-facing wall a drifted PVC intake can shut down an otherwise healthy furnace while nobody is home to clear it.
