Your heating system is working fine. You’re comfortable. Everything seems good. So why wait until something breaks down during a freezing night to think about maintenance?
Here’s the truth: one hour of preventive maintenance now can save you thousands in emergency repairs later. Plus, a well-maintained heating system runs 15-25% more efficiently, which means lower energy bills.
Let me walk you through a heating maintenance checklist you can do yourself—and when to call a professional.
What You Can Do Right Now (15 Minutes)
Check and replace your air filter
This is the easiest and most important task. Your heating filter should be checked monthly and replaced every 1-3 months, depending on usage and air quality in your home.
A clogged filter forces your system to work harder, consuming more energy and potentially causing breakdowns. Filters cost $10-$40 and take seconds to replace.
Clear vents and registers
Walk through every room. Make sure furniture, curtains, or other objects aren’t blocking air vents. Blocked vents force your system to work overtime and create cold spots in your home.
Check your thermostat batteries
If you have a programmable or smart thermostat, replace the batteries now. Dead batteries mean your system won’t respond to temperature changes, and you might wake up to a freezing house.
Inspect the area around your furnace
Is there clutter around your heating unit? Remove it. Your system needs proper airflow to operate safely and efficiently. Also check that nothing is blocking the intake or exhaust pipes if you have a gas furnace.
What You Should Have a Professional Do (Annual)
Professional cleaning and inspection
A certified technician should inspect your entire system annually. They’ll check for leaks, test all components, clean internal parts, and identify potential problems before they become expensive repairs.
Test carbon monoxide detectors
If you have a gas heating system, working CO detectors are critical for safety. A professional will ensure they’re functioning properly.
Check ductwork for leaks
Professionals use specialized equipment to detect leaks in your ductwork. Even small leaks waste 15-30% of your heating energy.
Inspect the heat exchanger
This is where the magic happens in a furnace. Cracks in the heat exchanger can be dangerous. Only a professional should inspect this.
Seasonal Timing Matters
Early Fall (September-October): Schedule your professional maintenance NOW, before demand peaks. You’ll get faster appointments and potentially better pricing.
Mid-Winter (January-February): If you haven’t done it yet, do it now. Yes, it’s busier, but a breakdown in freezing weather is worse.
Spring (March-April): Do a final check before storing your heating system for the season.
The Numbers: Maintenance vs. Emergency Repairs
- Annual professional maintenance: $100-$200
- Emergency heating repair (middle of winter): $300-$800+
- Full furnace replacement: $3,000-$7,000+ (varies by brand, system capacity, and installation complexity)
Important note on pricing: Repair and replacement costs vary significantly depending on several factors:
- Brand and model: Premium brands typically cost 20-30% more than standard models
- System capacity: Larger homes require bigger heating systems, which cost more
- Installation difficulty: If your furnace or heating unit is located on an upper floor, attic, or difficult-to-access area, installation labor increases substantially
- Existing ductwork condition: If new ductwork installation is needed, expect additional costs
- Local labor rates: Prices in the San Francisco Bay Area tend to be higher than national averages
For an accurate quote tailored to your specific situation, our technicians will assess your home, system type, and installation location during the initial inspection.
One breakdown could cost you what you’d spend on maintenance for 5-10 years.
Red Flags: When to Call Right Away
Even with maintenance, watch for these warning signs:
- Strange noises (rattling, squealing, banging)
- Uneven heating (some rooms are cold)
- Rising energy bills with same usage
- Yellow pilot light (should be blue)
- Frequent on-off cycling
Don’t ignore these. A small problem caught early prevents major breakdowns.
