An evaporator coil replacement involves recovering refrigerant from the system, removing the old coil from the furnace or air handler plenum, installing a new matched evaporator coil, reconnecting refrigerant lines, replacing the filter drier, evacuating the system, recharging with the correct refrigerant amount, and testing system performance. Evaporator coils commonly fail from corrosion (especially in formaldehyde-laden air from new homes), manufacturing defects, or normal wear after 10-15 years.

Evaporator Coil Replacement en San Jose — Preguntas Frecuentes

How long does an evaporator coil last?+

Evaporator coils typically last 10-20 years. In Sacramento, where AC systems run heavily for 5-6 months, coils may wear toward the lower end. Coil failure is often indicated by refrigerant leaks that keep recurring after recharges.

Can I replace just the coil or do I need a full system?+

If your condenser is less than 8-10 years old and still in good condition, replacing just the evaporator coil is cost-effective. However, the new coil must match your condenser. If the condenser is also aging, a full system replacement may offer better long-term value.

Is the evaporator coil covered under warranty?+

Most manufacturers offer 5-10 year coil warranties (some offer limited lifetime). However, the warranty typically covers only the part — not labor. Registration within 60-90 days of installation is usually required for the full warranty term.
