Furnace Maintenance: Ensuring Safe and Efficient Operation
Regular maintenance isn’t just about performance—with furnaces, it’s also about safety. Our preventative maintenance services help identify potential issues before they become dangerous problems or costly repairs.
Our Sigler Standard™ maintenance for both gas and electric furnaces includes:
- Complete safety inspection of all components
- Burner cleaning and adjustment (for gas furnaces)
- Heat exchanger inspection for cracks or corrosion
- Electrical connection tightening and testing
- Thermostat calibration and programming verification
- Airflow testing and filter replacement
- Lubrication of all moving parts
- Carbon monoxide testing (for gas furnaces)
- Efficiency performance evaluation
The difference between heating systems that last 10 years versus 20+ years often comes down to maintenance quality. Our technicians don’t just perform basic checkups—they conduct thorough assessments that identify potential issues before they become expensive problems.
For maintenance-minded homeowners, we offer customized maintenance agreements that provide priority service, discounted repairs, and scheduled visits tailored to your specific system needs.
