For heating problems, we check ignition, safeties, thermostat demand, burners, blower operation, venting, fuel supply, and whether the system can run safely through a cold night.

When you call about Tankless Water Heater Making Noise in Mount Sinai, tell us what changed first, whether the system is still running, and if you noticed ice, water, odors, unusual noises, breaker trips, or weak airflow.
