🛠️ The DIY Furnace Maintenance Checklist for R‑32 Systems
Here’s the step‑by‑step guide you can save and use every heating season:
✅ 1️⃣ Turn Off Power and Gas
Why? Safety first — always.
-
Locate the furnace’s circuit breaker and turn it off.
-
Turn off the gas supply using the shut‑off valve.
✅ 2️⃣ Replace or Clean the Air Filter
Why? A clogged filter restricts airflow, making the furnace work harder.
How:
-
Check the filter every 30–60 days.
-
Replace disposable filters.
-
Wash and dry reusable filters.
For more details on selecting the right filter, check the EPA recommendations.
✅ 3️⃣ Inspect the Thermostat
Why? To ensure your heating cycles operate as intended.
How:
-
Remove the thermostat cover and dust it with a soft brush.
-
Confirm settings match your needs (switch to “Heat” and set to a desired temperature).
-
Replace batteries if applicable.

✅ 4️⃣ Check the Flame Sensor
Why? A dirty flame sensor can cause ignition failures.
How:
-
Turn off the furnace.
-
Remove the flame sensor.
-
Gently clean with steel wool or fine sandpaper.
-
Replace and restart the furnace.
More about flame sensor cleaning can be found at Energy.gov Home Heating Systems.
✅ 5️⃣ Vacuum the Blower Motor and Combustion Chamber
Why? Dust buildup reduces efficiency and airflow.
How:
-
Use a vacuum with a soft brush attachment.
-
Gently clean the blower motor and combustion chamber.
-
Be cautious around wiring and connections.
✅ 6️⃣ Lubricate Moving Parts
Why? Friction can cause wear and reduce efficiency.
How:
-
Consult your furnace manual for lubrication points.
-
Apply a few drops of manufacturer‑approved oil to the motor and blower shaft.
✅ 7️⃣ Check the Venting System
Why? Blocked or damaged vents can cause dangerous combustion gases to back up.
How:
-
Inspect vent pipes for obstructions or corrosion.
-
Confirm connections are secure.
-
Check for signs of condensation or moisture.
✅ 8️⃣ Test the Ignition System
Why? To confirm your furnace starts reliably.
How:
-
Observe the ignition cycle.
-
Listen for delays or abnormal sounds.
-
If needed, clean or replace the igniter.
✅ 9️⃣ Perform a Final System Test
Why? To confirm the furnace operates properly after maintenance.
How:
-
Restore gas and electrical connections.
-
Turn the thermostat to “Heat” and adjust the temperature higher than the room’s current temperature.
-
Observe the ignition, flame, and blower operations for any irregularities.
