Quick Decision Framework
- Safety first: red-tag issues (exchanger, venting) → replace.
- Cost rule: if repair > 30–40% of a new system and unit is 12–15+ years, consider replace.
- Comfort/efficiency: chronic hot/cold rooms, high bills, noisy starts → upgrade options.
- Parts & downtime: obsolete parts or frequent failures → replacement pays back.
Look at Life-Cycle Costs (Not Just Today’s Repair)
A lower AFUE furnace can cost more every winter. Replacements upgrade efficiency, airflow, and comfort, and may include manufacturer rebates. We’ll price both options and project savings so you can compare apples-to-apples.
Red Flags Suggesting It’s Time
- Cracked heat exchanger or venting issues
- Repeated igniter/flame sensor failures
- Excessive noise, vibration, or sooting
- Uneven heat, short cycles, or high CO readings
- Rising winter bills despite maintenance
Don’t Forget Ducts & Controls
Leaky or undersized ducts sabotage new equipment. We assess static pressure, seal leakage, and balance airflow. Smart thermostats add comfort and savings with scheduling and geofencing.
