HVAC Solutions for Commercial and Residential Customers


Since 1929, William E Kingswell has been the reliable name HVAC solutions for the Maryland, D.C., and Virginia regions.

“We take great pride in having inventory to fulfill months where we have no idea what’s coming, whether it’s going to be 100 degrees, 80 degrees, 10 degrees.”

No matter the season, we make sure our clients have reliable access to the heating and cooling products they need for their jobs right away.

“And it’s in our brochures, they’ll have it in stock. They don’t have to say, hey, we’ll get it in two days. Customer’s happy, I’m happy. And then we keep doing business. And there’s a reason I’ve been coming here 25 to 30 years.”

Centrally located, right off the Beltway and I-95, at W. E. Kingswell you get the best of all worlds.

“Good afternoon. Kingswell. Charles speaking…”

We’re family-run, proud of our dedication to customer service.

“It’s our motto. It’s what we do.”

And willing to take risks if it means coming through for our clients when they need us most.

“Most people only sell from an order. We sell for what we turn. Sometimes we over-buy just to take care of things we see coming. We take pride in being the little guy, but on a much larger scale than people think.”

The best brands in HVAC, and the best service in the industry, readily available under one roof.

“Reliability, dependability, and service ability.”

“They do what they say, they say what they do, and they’re always there for us.”

W.E. Kingswell. We’re proud of the company we keep.
