Is $245 to anti-corrosion spray coating for evaporator coil a fair price?
Project Details
The homeowner lives in a high-humidity coastal area in the South. Their previous indoor evaporator coil failed in just over 4 years due to formicary corrosion. They requested a protective coating for the warranty replacement coil but were denied a factory-coated unit by the warranty provider, leading to this on-site spray application.
Quote Details
On-site application of protective coating to a new indoor A-coil prior to installation to resist formicary corrosion. - Use of a single 12-ounce spray can for coating - Application performed on-site before assembly - Intended to provide increased resistance to pinhole leaks caused by VOCs and high humidity
