Repair costs vary based on the issue's complexity, unit age, and accessibility. Older units (median home built 1975) may need more labor for part replacements. Diagnostic fees range $80–$225.

Leaking tank or connections
Corrosion or loose fittings can cause leaks. A leaking tank usually requires replacement, while connection leaks may be repairable.
