About Us

National HVAC in Seaford has been in business since the 1950s. Locals may remember us as Comfort Heating, founded by the renowned John C. Hopkins. Over the years, Comfort Heating grew and experienced many changes. In the 1990s, we joined forces with National HVAC, and more recently, we were adopted by Service Logic, the largest privately-owned HVAC service company in the US. This is a great benefit for our customers, because of the access to broader resources it allows us to be a local company with national resources.

National HVAC Service has over 40 employees, most of whom live in Sussex County or the surrounding Delmarva communities. About half of our employees are seasoned veterans, who have been with the company for 20 years or more. This means the other half of our workforce is being trained and mentored by the best of the best. Furthermore, National HVAC believes in the importance of professional development for all our staff members. Most of our workforce are actively enrolled in training courses. Our experienced team is committed to embracing modern technology, and we make it a priority to stay up to date with cutting edge systems, energy-efficient products, and current best practices.

National HVAC invests heavily in the future of our workforce. We offer tuition reimbursement to our employees, as well as ongoing training opportunities. In addition, National HVAC partners with Sussex Tech to offer apprenticeship opportunities, and we play an active role on the Del Tech HVAC Advisory Committee.

Having roots in Sussex County, National HVAC supports a variety of community and nonprofit organizations. We are members of the Western Sussex Chamber of Commerce and are proud of the areas in central Delmarva that we serve.

We at National HVAC want to highlight the importance of being proactive instead of reactive. Preventative Maintenance can help ensure your heating and cooling system is running properly and is key to avoiding inconvenient disruptions year-round.

Our team can assist with all your mechanical needs. We are proud of our expertise in Heating, Ventilation, and Air Conditioning, and are licensed to provide residential, commercial, and light industrial services.
