Extending Your Heater’s Lifespan

Proper maintenance can significantly reduce long-term costs:

Annual Inspections

HVAC professionals recommend scheduling service before each heating season. This catches small issues before they become major problems.

Homeowners can:

  • Change filters regularly
  • Keep the area around the unit clean
  • Monitor for unusual noises or smells

For more complex tasks like igniter replacement, professional service is recommended.

  • Repair costs exceed 50% of replacement cost
  • Your heater is over 15 years old
  • Energy bills are increasing significantly
  • You experience frequent breakdowns

Cost-Saving Tips

Many HVAC companies offer annual service contracts that include priority scheduling and discounts on parts.

Scheduling maintenance in spring or summer may offer better availability and pricing.
