We pride ourselves on having the very best employees a company can have, starting from our office straight to your job site.

We customize ourselves to fit your needs and wants and only use the very best materials and equipment. Taking the cheap road only leads to more leaks, breaks, and problems, which means unhappy clients.

For 40 years now we have been servicing the Delmarva area. We have seen our employees raise families, and now, some of their kids have become First Class employees. Throughout our long history in southern Delaware and eastern Maryland, the idea has remained the same. A good well trained employee who is taken care of, equals quality service to our customers. Who knows, maybe the next technician that comes to your home will be a third generation First Class employee. You can rest assured, no matter who takes care of your plumbing, heating, air conditioning, or crawl space, they are a professional that First Class trusts to get the job done right.


The future of heating and cooling is a very exciting place to be. With computer controls and new types of energy around the corner, the future is bright. No one knows for sure what the future of heating and cooling will be especially with the inclusion of smart home controls and more efficient air filtration systems. What I can tell you is, First Class will be on the front edge of technology while keeping the old fashioned values that you and your neighbors have grown to trust in and expect from us.
