Gas Furnace Repair With a Straight Answer on Repair or Replace

What Furnace Repair Services Do We Provide?
Furnace repair is finding and fixing whatever keeps a gas furnace from heating your home properly, from a worn ignitor to a failed blower motor or control board. A furnace repair service visit from On Time Experts Heating, Air & Plumbing ends with the cause found, explained and, once you approve the price, fixed.
You need furnace repair when the furnace is not working at all, blows cool air, shuts off a few minutes after it starts, or makes a new banging or squealing sound. Most furnaces around O'Fallon sit in the basement, and if a high-efficiency unit is leaving water on the floor, a clogged condensate drain is a common cause.
When a repair is the sensible fix, that's what we'll recommend.
What Is Included in Our Furnace Repair Services?
A furnace repair visit can cover any of the following:
- Diagnosis: Track down no heat, short-cycling (turning on and off every few minutes), noises and error codes.
- Ignition and sensor repairs: Replace or clean ignitors, flame sensors, pressure switches and limit switches.
- Motor repairs: Repair or replace inducer motors, blower motors and capacitors.
- Controls: Repair control boards and thermostat wiring.
- Condensate drains: Clear drains and traps on high-efficiency furnaces.
- Safety checks: Check burners, gas pressure and venting after the repair.
If the furnace is near the end of its life, ask for repair and Furnace Installation prices side by side.
Why Is Professional Furnace Repair Important?
Many faults look the same from the thermostat, and guessing at parts gets expensive. Good furnace repair starts with testing.
Find the Real Cause
Common causes of a furnace not heating include:
- A clogged filter, which can choke airflow until the limit switch (a safety that shuts the burners off if the furnace overheats) trips
- A worn hot surface ignitor, the part that glows to light the gas
- A dirty flame sensor, the rod that confirms the burners lit, which can make the furnace quit within seconds
- An inducer motor fault, in the small fan that clears exhaust out the vent, or the pressure switch that checks it
- A failing blower motor or capacitor, the part that helps the motor start
Leave Gas and Carbon Monoxide Concerns to the Pros
Gas furnace repair means working on gas valves and burners, so it's a technician's job. The safe checks you can do first are in the FAQ below.
If your carbon monoxide alarm goes off, get everyone out, pets included, and call 911 or Spire from outside, and don't run the furnace until responders say it's clear. The EPA explains how carbon monoxide affects indoor air.
Keep Dust From Causing Breakdowns
Dirt, dust and debris are the number one cause of air conditioning and heating system breakdowns. Our fall Furnace Deep Clean and Tune-Up pulls and cleans the blower wheel, which can cut down on dust-related failures.

Frequently asked questions
Furnace repair cost depends mostly on which part failed, the furnace's age and model, and access. Cleaning a flame sensor or replacing an ignitor is a small job, while a blower motor or control board costs more.
On Time Experts Heating, Air & Plumbing tests the furnace first and gives upfront pricing before any furnace repair begins, so you decide with the number in hand.
Furnace repair is often worth it on an older furnace when one inexpensive part has failed and the rest of the system is sound.
It's usually time to compare replacement when the furnace is roughly 15 to 20 years old, needs a major part like a heat exchanger (the metal chamber that keeps combustion gases out of your air), or keeps needing repairs. Ask for repair and replacement prices side by side so you can decide with real numbers.
Yes, but get everyone out first, pets included, and call 911 or Spire from outside. Once responders say it's clear, schedule furnace repair before running the furnace again.
The furnace is one possible source, along with a gas water heater or a car in an attached garage. If you smell gas, leave and call Spire or 911 from outside.
Before calling for furnace repair, make sure the thermostat is set to heat and above room temperature, and swap out a dirty filter. Check the furnace breaker and the furnace's service switch, which looks like a light switch.
Confirm the front panel is fully closed, since a safety switch keeps the furnace off otherwise, and that a high-efficiency unit's condensate line isn't kinked. Leave burners, gas valves and relighting to a technician.
How Much Does Furnace Repair Cost?
Furnace repair is priced by the part and the time it takes.
Factors that can affect the cost include:

- Age and model: The furnace's age, brand and model.
- Furnace type: Standard or high-efficiency.
- Access: A tight corner of a finished basement.
- Number of problems: Whether more than one part needs attention.
