What is different about Wilmington properties?
Pollen, summer humidity, basement moisture, and long cooling cycles make drainage and coil cleanliness especially important in northern Delaware. Attic air handlers in rowhouses and Cape Cods need secondary drain pans and float switches that actually work.
Ask the responding provider for identity, applicable Delaware license information, a written diagnosis or scope, total price, and warranty terms.
