Quick Answer

What to do when your heating stops working in Locust Valley

Check your thermostat settings and batteries first. Then check the circuit breaker for your furnace or boiler. If the pilot light is out, follow manufacturer instructions to relight it. If none of these fix the issue, call a licensed HVAC technician for emergency repair.

How long does emergency heating repair take?

Most emergency heating repairs in Locust Valley are completed in 1–3 hours. Simple fixes like ignitor replacement or thermostat issues take under an hour. Complex repairs involving heat exchangers or control boards may take 2–4 hours.

When should you replace vs. repair your furnace?

Replace your furnace if it is over 15 years old, requires frequent repairs, or has a cracked heat exchanger. Repair is usually the better option if the system is under 10 years old, the repair costs less than 50% of replacement, and the unit still runs efficiently.
