    Repair vs. Replacement

    When to Repair

    For furnaces under 12 years old with minor issues - like a faulty ignitor, blower motor, or thermocouple - furnace repair is usually the best and most cost-effective option.

    When to Replace

    If your furnace is 15+ years old, the heat exchanger is cracked, or repair costs exceed 50% of a new unit - furnace replacement is the smarter long-term investment.

    Frequently Asked Questions

    How do I know if my furnace needs repair or replacement?

    Age, repair frequency, and cost are the key factors. If your furnace is under 12 and the repair is reasonable, we'll fix it. If it's 15+ and repairs keep stacking up, we'll recommend replacement options.

    How long does a furnace last in Illinois?

    With proper maintenance, most furnaces last 15-20 years in central Illinois. Harsh winters mean your furnace works hard - annual tune-ups help it last longer.

    How quickly can you get here for emergency furnace repair?

    We answer the phone 24/7 with a live operator and dispatch as soon as a technician is available, prioritizing the most urgent no-heat calls first. We do not guarantee a specific arrival time.

    Do you service all furnace brands?

    Yes - Carrier, Lennox, Trane, Goodman, Rheem, Bryant, and all other major brands. Our technicians are factory-trained and experienced.

    What does a new furnace cost?

    Furnace replacement costs vary based on system size, efficiency rating, and your home's needs. We provide free estimates with transparent, upfront pricing - no hidden fees.

    Why is my furnace blowing cold air?

    A furnace blowing cold air usually means the pilot light is out, the flame sensor is dirty, the thermostat is set to fan instead of heat, or the limit switch tripped from overheating. Check the thermostat first, then call us if cold air keeps coming through the vents.

    What temperature should I set my thermostat to in winter?

    Most central Illinois homes are most comfortable and efficient at 68 degrees during the day and 62 to 65 degrees at night. Lowering the thermostat 7 to 10 degrees while you sleep or are away can cut heating costs by up to 10 percent each year.

    How much does a new furnace cost in central Illinois?

    A new furnace in central Illinois typically ranges based on size, efficiency rating, and installation complexity. We provide a free in-home estimate with transparent flat-rate pricing before any work starts, plus financing options to spread out the cost.

    Is it safe to run a furnace that smells like burning?

    A burning smell the first time you run your furnace each fall is normal as dust burns off the heat exchanger. If the smell continues past an hour, smells like plastic or rotten eggs, or comes with smoke, shut the system off and call us immediately for safety.

    How long can I expect a new furnace to last?

    A new high-efficiency furnace installed in central Illinois lasts 15 to 20 years with annual maintenance. Skipping yearly tune-ups can cut that lifespan in half. We include warranty registration and a free first-year inspection on every furnace installation we perform.
