Common Furnace Signs You Need a Repair
Catching a problem early can save you from a total system failure. Contact us if you notice:
- No Heat or Weak Airflow: If your furnace is running but your home isn't getting warm, there could be an issue with the blower motor or ignition.
- Short Cycling: If your furnace turns on and off frequently, it’s likely overheating or has a faulty thermostat.
- Strange Noises: Banging, squealing, or rattling sounds often point to loose belts, broken components, or motor issues.
- Yellow Pilot Light: A healthy gas pilot light should be blue. A yellow flame can indicate a carbon monoxide risk or incomplete combustion.
- Rising Energy Bills: If your heating costs are skyrocketing without a change in usage, your furnace is likely working harder than it should due to a mechanical fault.

FREQUENTLY ASKED QUESTIONS
How much does furnace repair cost in St. Michael?
The cost varies depending on the specific issue, such as a faulty flame sensor versus a failed blower motor. We offer free estimates for major projects and transparent diagnostic fees so you know exactly what the repair entails.
Why is my furnace blowing cold air?
This is often caused by a dirty air filter, a tripped circuit breaker, or a pilot light/ignition failure. If changing your filter doesn't help, give us a call to inspect the internal components.
Should I repair or replace my furnace?
Most furnaces last 15–20 years. If your system is over 15 years old and the repair cost is more than 30% of a new unit, replacement is often the more cost-effective long-term choice.
How often should I change my furnace filter?
In Minnesota, where furnaces run heavily for several months, we recommend checking your filter every 30 days and replacing it at least every 90 days (or more often if you have pets).
What should I do if I smell gas?
If you smell a "rotten egg" odor, leave your home immediately, do not touch any light switches, and call your gas company or emergency services. Once the area is safe, call us to repair the leak.
