Furnace & Heating Repair — common questions
How fast can someone repair my furnace?
For no-heat emergencies during winter, most Twin Cities HVAC companies offer same-day and 24/7 service — call a licensed local contractor directly and they'll prioritize it. Most non-emergency repairs are scheduled within 1–2 business days.
Is it worth repairing an older furnace?
If your furnace is under 15 years old and the repair costs less than about a third of a new system, repair usually makes sense. A technician can show you real numbers for both repair and replacement so you can decide with no pressure.
Why is my furnace blowing cold air?
Common causes include a dirty flame sensor, a failed ignitor, a thermostat set to the wrong mode, or an overheating system shutting down the burners. A quick diagnostic pinpoints which one it is.
