Furnace Deep Clean and Tune-Up in O'Fallon, MO
Yearly Furnace Maintenance That Starts With the Blower Wheel
A Furnace Deep Clean and Tune-Up from On Time Experts Heating, Air & Plumbing is a yearly fall visit for your gas furnace. We take out and clean the blower wheel, clean the burners and flame sensor, and test the safety controls before heating season starts.
What Is Furnace Maintenance, and When Do You Need It?
Furnace maintenance is the yearly cleaning, testing and adjustment that keeps a gas furnace heating safely and efficiently. At On Time Experts Heating, Air & Plumbing, that visit is the Furnace Deep Clean and Tune-Up, and September or October is the time to book it.
In most homes around O'Fallon and St. Louis, the furnace sits in the basement near the laundry. Dust and dryer lint settle on the parts that move air and make heat, which is why our visit starts with the blower wheel.
What Is Included in a Furnace Deep Clean and Tune-Up?
Every visit covers the cleaning and the safety checks:
- Blower wheel pulled and cleaned: The barrel-shaped fan that pushes warm air through your ducts comes out of the cabinet and gets cleaned blade by blade.
- Burners and flame sensor cleaned: Including the thin rod that tells the furnace the burners lit.
- Ignition and venting checks: The ignitor, inducer motor (the fan that pushes exhaust out the vent) and venting, plus the condensate drain on high-efficiency furnaces.
- Heat exchanger look-over: The metal chamber that keeps combustion gases out of your air, checked for cracks, rust or overheating.
- Gas pressure and safety switches: Gas pressure set to specification, and the high-limit switch tested so the burners shut off if the furnace overheats.
- Carbon monoxide reading: Taken at the flue and around the furnace while it runs.
If your furnace has quit, start with Furnace Repair. Our heating technicians cover O'Fallon, St. Peters, Creve Coeur and nearby communities, and the Air Conditioner Deep Clean and Tune-Up handles the cooling side each spring.
We check the filter and thermostat before we leave.
Why Is a Furnace Deep Clean and Tune-Up Important?
Dirt, dust and debris are the number one cause of air conditioning and heating system breakdowns. A clean furnace moves more air and works less hard.
A Clean Blower Wheel Moves More Warm Air
Every bit of warm air your furnace sends upstairs is pushed by the blower wheel. Its curved blades catch the fine dust that slips past the filter, and as that layer builds, the wheel moves less air.
Pulling the blower assembly takes time, so plenty of maintenance visits skip it. Ask your technician to show you the wheel before it goes back in.
Less Heat Trapped Around the Heat Exchanger
With less airflow, heat builds up around the heat exchanger and the furnace runs longer to warm the house. That can trip the high-limit switch, wear parts sooner and add to your Spire bill.
Safety Checks Done Before the Cold Weather
The gas pressure, burner and heat exchanger checks on ENERGY STAR's heating and cooling maintenance checklist are part of the visit, so a worn ignitor turns up on a planned day instead of the first cold night.
What Happens During a Furnace Deep Clean and Tune-Up Visit?
Here's how the visit runs:
- Tell us how it's been running. Your technician lays down floor protection and asks about noises or cold rooms.
- Pull and clean the blower. With the power and gas off, we take out the blower assembly and clean the wheel.
- Clean the burner side. We clean the burners and flame sensor and check the ignitor, venting and heat exchanger.
- Run and test. With power and gas back on, we run a heating cycle, measure gas pressure and carbon monoxide, and test the safety switches.
- Go over what we found. Any repair is priced first, and the decision is yours.
The furnace is back together and running before we leave.
Frequently asked questions
Yes. A Furnace Deep Clean and Tune-Up includes a carbon monoxide reading at the flue and around the furnace, which helps confirm exhaust is venting outside.
Every home with a gas furnace should also have working carbon monoxide alarms. If an alarm sounds or you smell gas, leave the house and call 911 or Spire from outside. Don't flip switches or look for the source yourself.
A Furnace Deep Clean and Tune-Up takes the dirtiest parts out of the furnace and cleans them, while basic furnace maintenance often stops at a look-over and a new filter.
The biggest difference is the blower wheel. The technician pulls the blower assembly out and cleans each blade, then cleans the burners and flame sensor and tests gas pressure, carbon monoxide and the safety switches.
Once a year is the usual schedule for a Furnace Deep Clean and Tune-Up, ideally in September or October.
A fall visit means a worn ignitor or dirty flame sensor turns up at a planned appointment. Paired with a spring Air Conditioner Deep Clean and Tune-Up, it covers both seasons.
Between visits, change the filter on schedule, often every one to three months, and more often with pets or a dusty basement. Keep boxes, laundry and paint cans a few feet from the furnace.
Keep vents and returns open and clear. Leave the burners, gas valve and wiring to a technician, and call if the furnace keeps shutting off and restarting.
How Much Does a Furnace Deep Clean and Tune-Up Cost?
The price depends on your equipment and what we find inside. Factors that can affect the cost include:
- Furnace type: A standard furnace, or a high-efficiency model with a condensate drain.
- Buildup: How much dirt is on the blower wheel and burners.
- Access: An attic or a tight closet.
- Repairs found: Quoted separately and never started without your approval.
