Furnace Maintenance Checklist
A little maintenance prevents the classic “no heat at 2am” problem. If you’re already without heat, call 888-821-1652.
Monthly
- • Check/replace the air filter (1–3 months typical)
- • Keep supply/return vents clear
- • Listen for new noises or short-cycling
Seasonal (before cold snaps)
- • Test heat early (don’t wait for the first freezing night)
- • Confirm thermostat settings and batteries
- • Make sure the exhaust/intake area is unobstructed
FAQ
How often should I change my furnace filter?
Every 1–3 months for most homes; monthly if pets/allergies or heavy use.
When should I call a pro instead of DIY?
If there’s any safety concern (gas smell/soot), persistent ignition issues, or abnormal cycling/noises.
