D.E. Duffey & Sons has been keeping families in suburban Philadelphia comfortable since 1898 when the company was founded by D.E. Duffey.

Today, the company is headed up by Dan Duffey, President, who is involved in every aspect of the business.

Experienced

This isn’t just a business for us, it’s our family and our family reputation on the line everyday.

D.E. Duffey still carries on the family traditions of prompt, courteous service with a knowledgeable staff and a large fleet of trucks that are available 24/7.

One of the first things our customers notice about D.E. Duffey & Sons is that we’re not interested injust making a quick sale and moving on. We take pride in establishing long-term relationships with customers…from assisting in the selection and installation of a new heating/cooling system, to providing maintenance through our service contracts and supplying heating oil. We earn the trust of our customers with dependable service and hard work.
