Fall Is Around the Corner! —Time to Get Your Furnace Ready!

Cooler mornings and crisp evenings are just around the corner, which means it’s furnace season again. Before the first chill hits, invest a little time in your heating system. A pre-winter furnace tune-up boosts safety, efficiency, and comfort—for you and your family.

Why Prepping Your Furnace Matters

A well-maintained furnace runs more reliably and uses less energy. Dirty filters or worn parts force the blower motor to work harder, driving up your utility bill. Regular checks can catch small issues—like a failing pressure switch—before they turn into expensive repairs or safety hazards.

DIY Furnace Check-Up Checklist

• Replace or clean the air filter every 1–3 months

• Vacuum dust and debris around the furnace base and vents

• Inspect the thermostat battery and settings for consistent heat

• Listen for unusual rattles or squeaks when the blower starts

• Check pilot light color (steady blue flame) or electronic ignition function

Key Components to Inspect

• Blower Motor: Look for unusual noise or vibration

• Limit Switch: Ensure the furnace shuts off at the correct temperature

• Pressure Switch: Confirm proper venting and combustion airflow

• Flame Sensor: Clean gently with fine sandpaper for reliable ignition

• Heat Exchanger: Scan for cracks or corrosion that could leak carbon monoxide

When to email us for assistance! 

• Strange odors (burnt dust vs. gas smell) persist after filter change

• Pilot light won’t stay lit or burners fail to ignite

• Frequent cycling on and off without reaching the set temperature

• Carbon monoxide detector alerts or visible rust on vent pipes

• Your system is over 15 years old—consider efficiency upgrades
