Signs It's Time for a New Furnace
- Your current furnace or boiler is over 15–20 years old
- The cost to repair your broken system is more than 50% of the cost of a new one
- You have a cracked heat exchanger (which is unsafe and costly to replace)
- Your current system has a low AFUE rating (under 80%), wasting expensive gas
- Your home is consistently uncomfortable, with drafts and cold spots
- The unit has required multiple expensive repairs over the last two winters
