What a Fox Heating Tune-Up Covers
A real safety and performance check — the stuff that keeps a furnace running clean and safe.
Inspect the Heat Exchanger
A cracked heat exchanger can leak carbon monoxide — we check it closely for your family's safety.
Test Ignitor & Burners
Clean, reliable ignition so your furnace lights every time you need it.
Clean the Flame Sensor
A dirty flame sensor is the #1 reason a furnace starts, then shuts right back off.
Test Safety Controls
Limit switches and shutoffs that protect your home — checked and verified.
Check Filter & Airflow
A fresh filter protects the furnace and improves the air your family breathes.
Combustion & CO Safety Check
We confirm your system is burning clean and safe before we leave.

Heating Maintenance Questions We Hear a Lot
How often should I service my heater?
At least once a year — ideally in the fall before winter. An annual check keeps your furnace safe, efficient, and reliable when the first cold snap arrives.
What's included in a heating tune-up?
We inspect the heat exchanger, test the ignitor and burners, clean the flame sensor, check safety controls, check the filter and airflow, and run a full combustion and carbon-monoxide safety check.
Why does furnace maintenance matter for safety?
Gas furnaces burn fuel, so a cracked heat exchanger or poor combustion can create a carbon-monoxide risk. A yearly inspection catches these issues and keeps your home safe.
Will maintenance lower my heating bill?
Yes — a clean, properly tuned furnace burns more efficiently, which lowers your winter bills and helps the system last longer.
Do you offer a maintenance plan?
Ask us about our maintenance plan for seasonal reminders and priority service, so your heat is ready before you need it.
