Furnace Repair or Furnace Installation: Your O’Fallon IL Question

Your O’Fallon IL Furnace Installation Guidefurnace installation O'Fallon Illinois

Few things are more frustrating than a furnace outage on a cold winter night. Residents of O’Fallon, IL know this as well as anyone, where winter temperatures routinely dip into the low teens. However, what may be more frustrating, is a furnace that routinely breaks when you need it most, prompting repairs from your local heating and cooling specialist. Furthermore, when these repairs start adding up, it may be a better option just to get it replaced. I know what you’re thinking – “how do I know when it’s time for a new furnace installation?” That depends on the cost of repairs versus the cost of replacement. Here is a breakdown of how much your repairs are costing and how much a new furnace installation could save you!

Furnace Warning Signs

If you’re calling for furnace repairs, it’s likely that you’ve already noticed and reported the problems, but take note of anything unusual when it comes to your heating system. Common furnace warning signs include:

  • Varying temperatures from room to room
  • Loud noises while the furnace is running (clanking, thumping, rumbling, etc.)
  • Furnace blows cold or lukewarm air
  • Furnace cycles too frequently (shutting on/off)
  • Heating unit is blowing out large amounts of dust (even after filter is changed)
  • Smell of a gas leak

If you notice something strange with your unit, don’t wait. Make sure you call a professional to ensure you aren’t ignoring something important.


This component of your furnace system is what turns the furnace on and starts the process of heating the air for your home. Igniters themselves are not expensive, making the total cost manageable when you add in labor fees – you won’t be changing your own igniter.

The Heat Exchanger

The heat exchanger is responsible for transferring the heat created in the heating coils to the hair before being distributed throughout the home. Repairs for this part can be pricey, and a complete replacement of the part could cost some serious coin. This repair may have you thinking about furnace replacement.


This part of your furnace distributes the warm air created by your furnace by blowing it through the ventilation system. This repair also qualifies as manageable. A simple google search for the part returns options that range from about $100 to about $300 – add in labor, and this isn’t a deal-breaking fix, either.

Flame Sensor/Thermocouple

Both of these devices are used for precautionary purposes, and they ensure that gas or oil valves are only open when they need to be.  A faulty flame sensor or thermocouple may cause a gas leak. However, the part is inexpensive, and the repair should be quick if you call a qualified HVAC technician.

New Furnace Installation Cost

When you add up the cost of parts, labor, energy wasted, your best bet could be a new furnace installation. However, you’ll have to carefully way your options and pricing will certainly vary depending on your desired usage, the size of your home or business, and other factors. A new furnace could cost anywhere between $2,000 and $10,000.
