Common Furnace Problems We Diagnose

Furnace Blowing Cold Air

A furnace may circulate air without heating it because of ignition issues, thermostat settings, restricted airflow, or other component problems.

Furnace Won’t Turn On

Power supply issues, control problems, ignition failures, or safety-related shutdowns may prevent normal operation.

Furnace Starts but Quickly Shuts Off

Frequent cycling can result from overheating, restricted airflow, controls, or equipment problems.

Furnace Makes Unusual Noises

Banging, rattling, squealing, and grinding may indicate loose components, blower problems, or other mechanical concerns.

Furnace Runs but the House Stays Cold

The issue may involve equipment performance, ductwork, insulation, or the building’s heating requirements.

Weak Airflow From Heating Vents

Filters, ductwork restrictions, and blower-related problems may reduce airflow.

Our Furnace Repair Approach

We begin by discussing what you’ve noticed and when the problem occurs.

Next, we evaluate relevant furnace components, controls, airflow, and operating conditions.



After identifying the issue, we discuss the repair options and appropriate next steps.

When to Schedule Furnace Service

Contact a heating professional if your furnace repeatedly shuts down, produces inadequate heat, makes unfamiliar noises, or fails to start.



If you smell gas, leave the building immediately and contact your gas utility or emergency services from a safe location.
