Unmatched Furnace Replacement

Signs Your Old Heating System Needs to Go

If your furnace is struggling to keep up, it might be time for an upgrade. At Trilogy AC Cooling and Heating, we help homeowners recognize the warning signs before they’re left in the cold. Here’s what to watch for:

  • Age and decreased efficiency: If your furnace is 15 to 20 years old and no longer heating effectively, it may be nearing the end of its lifespan and costing you more in energy.

  • Frequent breakdowns and costly repairs: Multiple repairs in a season can add up quickly—often exceeding the cost of investing in a new, reliable system.

  • Rising energy bills: A noticeable increase in heating costs with no change in usage often points to a failing or inefficient furnace.

  • Uneven heating throughout the home: Cold spots or inconsistent warmth may signal that your current system can no longer meet your home’s heating demands.

  • Strange noises or constant cycling: Loud bangs, rattling, or nonstop on-off cycling indicate internal problems and a system that may be close to failure.
