Common warning signs in our area include a yellow or flickering burner flame (it should be blue and steady), visible soot or rust around your furnace, excessive moisture on windows near the unit, and a persistent stale or burning smell. If you notice any of these, it's crucial to shut off the system and call us immediately for a safety inspection to protect your household.

Short cycling is often caused by an oversized unit, a clogged air filter restricting airflow, or a faulty thermostat reading temperatures incorrectly. This constant on-and-off cycle puts immense strain on your system, drastically increases energy bills, and fails to heat your home evenly. We can diagnose the root cause—whether it's a simple fix or a sizing issue—and provide the right repair to restore steady, efficient operation.

We recommend an annual professional tune-up before each heating season. Our Hanover-focused service includes a thorough safety check for carbon monoxide leaks, cleaning of critical components to ensure proper airflow and prevent short cycling, testing of system controls, and inspection of the heat exchanger for cracks. This proactive maintenance is your best defense against breakdowns, safety hazards, and high energy costs.
