When Should You Replace Your Furnace?
(How do you know it’s time?)
Most Michigan furnaces last 13–15 years, depending on maintenance and usage. But certain signs indicate it’s time to replace your system sooner:
- Your furnace is 15–20+ years old
Older units cost more to operate and fail more often — especially during extreme cold. - Frequent repairs
If you’re calling for repair more than once a year, replacement is often cheaper long-term. - Rising energy bills
Inefficient furnaces use more fuel to produce the same amount of heat. - Uneven heating or weak airflow
Rooms that won’t warm up indicate a failing blower motor or heat exchanger. - Strange noises or smells
Banging, grinding, rattling, or burning odors are red flags. - Yellow furnace flame
A properly working furnace burns blue. A yellow flame can indicate dangerous combustion issues. - The furnace can’t keep up during winter.
When the system runs constantly but still can’t heat the home, it’s failing internally.
If you’re unsure, we can inspect your system and give honest recommendations — with no pressure.

Repair vs. Replacement — What’s the Best Choice?
(This is the most common question we get.)
Sometimes a furnace can be repaired affordably. Other times, replacement is safer and more cost-effective.
We generally recommend replacement if:
- The cost of repair is 30–40% of the cost of a new furnace
- Your furnace has a major failure (heat exchanger, control board, or blower motor)
- Your system is older than 15 years
- You’re planning to sell soon and want energy-efficient upgrades
- You want more comfort, quieter operation, or lower monthly bills
We always provide repair and replacement options so YOU can choose what’s best for your home and budget.
