Repair or Replace? Here's How We Think About It.
We'll always give you both options. Here's a general framework we use.
Repair makes sense when…
- System is under 10 years old
- Repair cost is less than 50% of replacement value
- No pattern of recurring breakdowns
- Heat exchanger is intact (critical safety component)
Replacement makes sense when…
- System is 15+ years old
- Repair costs are stacking up season after season
- Heat exchanger is cracked — a safety and carbon monoxide concern
- Efficiency is low and you're paying for it in utility bills every month
Let's talk through your options.
Call (503) 980-5587A Note on Cracked Heat Exchangers
A cracked heat exchanger is one of the most serious furnace issues we encounter. It allows combustion gases — including carbon monoxide — to mix with the air circulating through your home. If a technician tells you your heat exchanger is cracked, don't run the system until it's been inspected by a second opinion you trust. We will always show you the problem directly and explain your options clearly.
