Common Questions

Why is my heater blowing cold air?

This is a common issue that could be caused by a dirty flame sensor, a faulty igniter, a broken thermostat, or simply a severely clogged air filter blocking the airflow.

Is it safe to run my furnace if it smells funny?

A brief “burning dust” smell the first time you turn it on for the winter is normal. However, if it smells like gas, burning plastic, or electrical smoke, turn the system off immediately and call us.
