Here are common heating issues Cotati homeowners face and how we handle them:

• Heater will not turn on at all. Often caused by a faulty thermostat, a broken ignition system, a gas valve problem, or an electrical failure. We perform a full ignition and electrical inspection, test gas lines, and replace parts if needed.

• Heater runs but the air feels cold or weak. This might be a clogged filter, dirty burners, a worn blower motor, or a damaged heat exchanger. We clean or replace filters, clean burners, test motors, inspect heat exchangers, and check airflow.

• Strange noises like banging, rattling, squealing, or humming. This can result from loose parts, worn bearings, failing blower motors, or debris inside the system. We inspect the internal parts, tighten or replace worn components, and restore safe operation.

• Unusual smells like gas, burning, or musty odors. This can be a sign of clogged burners, overheating, dirty filters, or a dangerous gas or combustion issue. We run a combustion analysis, check the heat exchanger, test flame sensors, and inspect ventilation.

• Heater turns on and off too often. Known as short cycling. This can be caused by thermostat problems, dirty filters, weak airflow, or broken safety sensors. We check the thermostat, sensors, filters, and airflow.

• High energy bills and poor heating performance. Older or neglected heating systems lose efficiency. We repair worn parts, seal ducts, clean vents, and recommend energy efficient upgrades if needed.

If you notice any of these issues, call a licensed professional as soon as possible. Heating problems can get worse quickly and may affect safety.
