No heat?
When your furnace stops working in a Minnesota winter, you need answers quickly. Call 612-520-1623 and tell us what’s happening. Emergency furnace repair is available.
In the meantime, a few safe checks are fine: make sure the thermostat is set to heat and above the current room temperature, and check that the thermostat has power. Please don’t attempt to repair gas or electrical components yourself. See furnace safety below.
Common furnace problems
Furnace not heating
The furnace runs but the house stays cold, or heats only slightly. We look at how the system is operating before recommending a repair.
Furnace won’t start
Nothing happens when the thermostat calls for heat. The cause may be in the thermostat, the power supply or the furnace itself.
Furnace blowing cold air
Cold air from the vents can have several causes. A technician needs to check the system to identify which one applies.
Furnace making noise
Banging, squealing, rattling or grinding are worth having checked. New noises can be an early warning.
Furnace turning on and off
Frequent short cycles are a sign the system isn’t operating normally.
Uneven heat from room to room
Some rooms comfortable, others cold. We look at airflow and system operation.
What we check
- Thermostat operation and settings
- Power and control components
- Ignition and burner operation (by a qualified technician)
- Airflow, including filter condition and blower operation
- Venting and general system condition
- How the furnace is performing overall
We explain what we find in plain language and go over your options before any work begins.
Repair vs. replacement
A repair is often the practical solution. Sometimes the condition of the furnace or repeated breakdowns make replacement worth talking about. We evaluate the equipment and discuss practical options before recommending major replacement.

Safety first
Furnaces burn fuel and use electricity, so some problems are safety problems. Never try to repair gas or electrical furnace components yourself.
- Smell gas? Leave the home right away and call your gas utility or 911 from outside.
- Carbon monoxide alarm sounding? Get everyone, including pets, outside into fresh air and call 911.
- Working CO and smoke alarms. Test them regularly and replace batteries as needed.
Minnesota considerations
Minnesota winter heating
Furnaces in Twin Cities homes run for months, through long stretches of subzero temperatures. That’s a lot of run time, and a failure on the coldest night of the year is the last thing anyone wants.
We don’t say this to frighten anyone; it’s simply why routine service matters. See furnace maintenance, cleaning & tune-ups.
