Professional Furnace Maintenance Checklist

Ever wonder what you’re actually paying for during a furnace tune-up? At TemperaturePro Katy-Cypress, we believe in transparency, so here’s the full checklist our certified technicians work through on a professional maintenance visit. Knowing what’s included helps you understand the value—and spot the difference between a real tune-up and a quick once-over.

Here’s what a thorough furnace maintenance visit covers.

Our Professional Furnace Maintenance Checklist

• Combustion and safety testing – CO testing, combustion analysis, and draft verification to confirm safe operation.
• Heat exchanger inspection – Checking for cracks, corrosion, or soot that could pose a safety risk.
• Burner and flame sensor service – Cleaning burners and the flame sensor for reliable, efficient ignition.
• Ignition system check – Testing the igniter, voltage, and ignition sequence.
• Electrical inspection – Checking capacitors, relays, control board, wiring, and connections.
• Blower and motor service – Inspecting the blower wheel, motor amperage, and bearings; cleaning as needed.
• Airflow and temperature rise – Verifying filter condition, static pressure, and proper heat rise.
• Thermostat calibration – Confirming accurate temperature control and proper cycling.
• Gas pressure check – Measuring and adjusting manifold pressure to spec on gas systems.
• Overall performance verification – Confirming the system heats safely and efficiently before we leave.

Why Each Step Matters

These checks aren’t busywork—each targets a common failure point. Combustion and heat exchanger checks protect your family’s safety; burner and sensor cleaning prevents the ignition lockouts that cause most no-heat calls; airflow and electrical checks prevent overheating and component failure. Together they keep your system safe, efficient, and reliable. See the benefits of professional maintenance and what’s included in our annual tune-up.
