What’s Included in Our Comprehensive 18-Point Furnace Maintenance Service?

Our certified technicians follow a rigorous checklist to ensure every component of your gas or electric furnace is inspected, cleaned, and tested for peak performance. This isn’t just a quick check—it’s preventative care designed to save you money and headaches.

Safety & Performance Assurance

• Carbon Monoxide Testing: We check for deadly CO leaks to keep your family safe—a vital step often missed by others.
• Gas Pressure and Airflow Measurement: Calibration ensures optimal fuel consumption and heat delivery.
• Thermostat Calibration: Testing and adjustment for accurate, comfortable temperature control.

Deep Cleaning & Component Efficiency

• Air Filter Service: Cleaning or replacement of the air filter (essential for air quality and efficiency).
• Blower and Burner Cleaning: Deep cleaning of the blower motor, fan assembly, and burner assembly to remove performance-robbing soot and debris.
• Lubrication: Application of high-grade lubricant to all moving parts to prevent premature wear and tear.

Inspection & Preventative Repair

• Heat Exchanger Visual Inspection: Careful check for dangerous cracks or damage that could lead to failures.
• Electrical System Check: Inspection of all wiring, connections, igniters, and capacitors. A faulty connection could lead to an emergency Furnace Repair.
