What influences repair costs in Lafayette?
Repair costs vary based on the issue's complexity, the unit's age, and local labor rates. Permit fees and the need for a licensed plumber add to the total.

Sediment buildup
Hard water and sediment accumulate over time, reducing efficiency and causing rumbling noises.
Heating element failure

Corrosion or loose fittings can cause leaks, especially in older units from the 1980s.
