Start with age, failure type, and comfort
A simple part failure on a newer system is different from a major repair on equipment that has been unreliable for years.
Comfort problems also matter. If rooms are uneven, humidity is poor, or the system is noisy, replacing equipment without reviewing airflow may not solve the issue.
Repair makes sense when the system still has life
Minor ignition, blower, thermostat, drain, or electrical issues can often be repaired without turning the call into a replacement project.
A clear diagnostic should explain what failed, what the repair changes, and what risks remain.
Replacement deserves attention when repairs repeat
If repair costs are climbing, parts are harder to source, efficiency is poor, or the system is mismatched to the home, replacement may be the practical route.
The quote should include equipment, installation details, venting, electrical, thermostat setup, disposal, and commissioning.
