Annual Professional Inspections

Schedule professional maintenance before each heating season. Certified technicians perform critical checks most homeowners miss:

• Combustion analysis to verify proper gas/air mixture
• Heat exchanger inspection for cracks or corrosion
• Electrical component testing for safe operation
• Gas line pressure verification

For complex systems like tankless water heaters, professional servicing is especially crucial to prevent mineral buildup.

Monthly DIY Maintenance Tasks

Filter Replacement

Clogged filters reduce airflow by up to 50%. Check filters monthly during heating season:

Ventilation Check

Clear all intake and exhaust vents of:

• Snow/ice accumulation
• Bird nests or debris
• Overgrown vegetation

Seasonal Preparation

Pre-Winter Startup

1. Test thermostat operation
2. Lubricate moving parts (if applicable)
3. Check pilot light or ignition system
4. Verify carbon monoxide detectors function

Post-Season Shutdown

For systems like pool heaters:

• Drain all water to prevent freezing
• Cover exposed components
• Disconnect power sources

Troubleshooting Common Issues

Uneven Heating

Possible causes and solutions:

• Dirty burners: Clean with brass brush (turn off gas first)
• Blocked vents: Clear obstructions from registers
• Duct leaks: Seal with mastic tape (not duct tape)

Strange Noises

According to U.S. Department of Energy, unusual sounds often indicate:

• Loose components (rattling)
• Dirty blower wheel (scraping)
• Ignition problems (popping)

Specialty Heater Care

Electric Heaters

For decorative electric heaters:

• Dust coils quarterly with soft brush
• Check cord insulation for cracks
• Verify stable surface placement

Hydronic Systems

Annual maintenance includes:

• Bleeding air from radiators
• Testing pressure relief valve
• Inspecting circulator pump

Energy Efficiency Upgrades

The ENERGY STAR program recommends:

• Installing programmable thermostats
• Adding insulation to exposed pipes
• Sealing ductwork with mastic
• Upgrading to high-efficiency models when replacing old units
