When Is It Time for a New Furnace?

Furnace is 15–20+ years old
Frequent repairs in the past two seasons
Energy bills keep rising without reason
Some rooms always feel colder than others
Unusual noises like banging, rattling, or humming
Furnace struggles to keep up in very cold weather
We don’t push replacements you don’t need. If your system can be repaired and run efficiently, we’ll let you know. If a new system is the better long-term value, we’ll walk you through every step of the process.
