Why does my furnace keep turning on and off?

Short cycling is often a dirty flame sensor, restricted airflow from a clogged filter, or an overheating limit switch. It's inefficient and wears parts fast, so don't ignore it — a contractor can usually resolve it in one visit.

Is a cracked heat exchanger dangerous?

Yes — a cracked heat exchanger can allow carbon monoxide into your home's airflow. Warning signs include soot around the furnace, a flickering burner flame, or headaches and nausea when the heat runs. This is a replace-the-furnace situation and a safety priority: call immediately.

How often should I replace my furnace filter?

Check monthly during heating season; most 1-inch filters need replacement every 1–3 months. A clogged filter is the #1 cause of airflow-related furnace failures and frozen AC coils alike.

My furnace is 18 years old and needs a repair. Should I fix it or replace it?

Furnaces typically last 15–20 years. At 18 with a major failure — especially a heat exchanger or control board — replacement usually makes more sense than another repair. Ask the contractor to assess both paths honestly during the visit.

Do heating contractors offer free estimates?

Many independent contractors in our network offer free estimates. Confirm when you call so you know exactly what to expect from the visit.
