Grasonville and Chester sit on opposite sides of the Kent Narrows area. The county plan describes connections between its homes, businesses and waterfront uses. For a visit near the Narrows, give us the street address and entrance details, especially when several buildings share a property.
A Separate Workshop or Addition
If a workshop or addition in Grasonville sits beyond the main ductwork, start by describing how you use it. Occasional use and daily use can call for different choices. Ductless mini-splits are one way to heat and cool a space without extending the ducts.
Access Matters at a Business
For commercial heating and cooling, tell us which rooms are affected, when people use them and how to reach the equipment. A customer entrance may not be the best route for a service visit. Call to discuss availability; this page does not promise a response time.
