Expert Heating Maintenance

A yearly heating tune-up keeps your furnace safe and efficient through Monrovia's cooler months. Our maintenance visits include burner inspection, filter replacement, and carbon monoxide safety checks.

Why Fall Heating Maintenance Matters in Monrovia

  • Carbon Monoxide Safety: A heat exchanger crack is invisible to the naked eye and potentially deadly. We use inspection cameras and CO analyzers — standard visual checks are not sufficient.
  • Pilot Light & Ignition Cleaning: Pilot assemblies and hot surface igniters accumulate oxidation over the off-season. Cleaning them before the heating season prevents the frustrating first-cold-night failure.
  • Blower Motor Lubrication: Many older Monrovia furnaces have PSC blower motors that need seasonal lubrication to prevent bearing seizure.
  • Filter Assessment: A filter loaded with Monrovia's foothill dust from all summer AC use needs replacement before the heating season begins.
  • Thermostat Mode Testing: Switchover issues between cooling and heating modes are best discovered during a maintenance visit, not during a cold snap.

What Our Fall Heating Tune-Up Covers

Our heating maintenance visit is a comprehensive safety-first inspection designed around the specific risks of gas combustion appliances. We don't treat it as a quick visual scan — we actually test each safety component to confirm it operates within manufacturer specification. The goal is to enter the heating season knowing with certainty that your system is safe, efficient, and ready to perform.

Our Heating Tune-Up Checklist

Every system receives a thorough inspection covering safety and performance:

  • 1. Burner Assembly Cleaning: We remove and clean the burner assembly to ensure clean, complete combustion and eliminate soot buildup.
  • 2. Heat Exchanger Camera Inspection: We use a flexible inspection camera to visually inspect the inside of the heat exchanger for cracks or holes.
  • 3. Safety Control Verification: High-limit switch, rollout switch, and pressure switch operation are each tested individually.
  • 4. Gas Pressure & Combustion Analysis: We measure manifold pressure and use a combustion analyzer to verify the flue gases show complete, safe burning.
  • 5. Final CO Ambient Test: We measure carbon monoxide levels in the living space after the system has been running for 15 minutes.
