What is different about Wilmington properties?
Many Wilmington-area furnaces share an old masonry chimney with the water heater, or vent through a side wall on high-efficiency models. Venting checks matter as much as the burner cleaning, especially after a winter storm.
Ask the responding provider for identity, applicable Delaware license information, a written diagnosis or scope, total price, and warranty terms.
