Furnace Repair FAQs
Q: Why Does My Furnace Turn On and Off Every Few Minutes?
A: This issue is called short cycling, and it’s one of the most common heating problems we see in New Jersey homes
Q: Is It Safe to Run a Furnace That Smells Like Burning?
A: A burning smell is not something to ignore. While sometimes harmless, it can also signal a serious safety issue
Q: How Long Should a Heating System Last in New Jersey’s Climate?
A: In New Jersey, heating systems work harder due to cold winters and frequent cycling. Because of that, lifespan depends heavily on maintenance and installation quality.
Typical life expectancy:
-
Gas Furnace: 15–20 years
-
Boiler: 20–25 years
-
Heat Pump: 12–15 years (shorter due to year-round use)

Repair Warning Signs
Cold rooms, weak airflow, unusual noises, frequent restarts, or a furnace that runs without reaching your thermostat setting are reasons to schedule a diagnostic visit.
This is called short cycling. Our diagnostic process checks airflow, electrical controls, and system operation to identify the cause before recommending repairs.
Pricing & Replacement Questions
We offer a $75 diagnostic service. Repair costs depend on the problem and any parts required. You receive an explanation and upfront repair pricing before work begins.
Age alone does not determine whether replacement is necessary. We assess the furnace’s condition, safety, and performance, then explain whether repair is a practical option.
