What is different about Wilmington properties?
Wilmington homes include steam and hot-water boilers, gas and oil furnaces, electric systems, and modern heat pumps. Older piping, chimneys, fuel conversions, and mixed additions require system-specific judgment, so tell the dispatcher exactly what you have.
Ask the responding provider for identity, applicable Delaware license information, a written diagnosis or scope, total price, and warranty terms.
