Common Signs When It’s Time for Furnace Replacement or Repair
Knowing when to repair vs replace helps protect your home and avoid costly repairs.
Key Red Flags That Your Furnace May Be Nearing the End
- Uneven heating: rooms not staying warm, longer run times, or rising energy bills.
- Strange noises: banging, rattling, or inconsistent burner flame.

Furnace Air Quality Issues: What to Watch For

When Furnace Problems Become Safety Hazards
