Furnace Repair FAQs

We understand homeowners have questions when their heating system acts up. Let’s go over some of the answers to the most common ones that we have received.

Regular maintenance is definitely the best way to avoid unexpected service calls. You should replace your air filter every one to three months, and schedule professional maintenance for your furnace annually. Proactive care extends the life of your unit. A professional tune-up helps your system run efficiently.
If your unit stops heating, you should first check your thermostat settings and circuit breaker. Make sure the thermostat is set to “Heat” and that the temperature is set above the current room temperature. If the issue is not electrical, call us immediately for heating system repair. We can provide you with a free replacement quote if the unit is beyond repair.
