Pennsylvania winters don’t ease in gently. Before the first hard freeze, a furnace tune-up protects both your comfort and your wallet. Here’s what a thorough seasonal check covers.
What to check before winter
- Replace the air filter. A clogged filter is the most common cause of weak airflow and short-cycling.
- Test the thermostat. Confirm it calls for heat accurately; consider a programmable or smart model to cut runtime.
- Inspect the flue and venting. Blocked venting can let carbon monoxide back up into the home.
- Clean the burners and check the flame. A steady blue flame means clean combustion.
- Listen for unusual noises. Banging, squealing, or rattling usually signals a part on its way out.
If your system is more than 15 years old or struggling to keep up, it may be time to weigh a repair against a replacement. A licensed technician can walk you through the options.
