We Have A Long History Here
Our company began as an office in a private residence back in 1962. Since then, we have continued to expand our reach and our capabilities. Today, we can manage your indoor air quality from end to end. That means you can rely on us as your single source for installation, repair, and maintenance of your heating, and cooling systems and automated climate control.
Thanks to our commitment to high-quality work and delivering HVAC systems that create comfortable working environments, we have enjoyed many years of growth. This has allowed us to expand our fleet and our staff. Today, we are equipped to offer our services to the entire state of Delaware and any location within one hour of our current headquarters.
Over the years, SUI has learned that the best way to provide consistent value for our clients is by routinely maintaining your systems and using the most energy-efficient methods. This is why we stress the importance of our service agreements and continual maintenance services. They are how you will get the most productive performance out of your systems.
Community Outreach
We are proud to be members of the local community here in New Castle, Delaware. Being your local provider of HVAC services has kept us in business and growing for more than half a century now, and we make sure to give back when we can.
These is a short list of the community outreach efforts and charitable organizations we have supported:
- Ronald McDonald House: Ronald McDonald House of Delaware is one part of a global charity that provides homes where the families of critically ill children can stay in times of need. There are many times when families must travel great distances to seek medical care for their children, and the high costs of hotels can become exorbitant. Ronald McDonald houses provide temporary housing for these families when they need it most.
- Leukemia & Lymphoma Society: The mission of the Leukemia & Lymphoma Society is to help cure leukemia, lymphoma, Hodgkin’s disease, and myeloma by funding research and to aid in improving the quality of life of patients and their families.
- Easterseals: “As America’s largest nonprofit healthcare organization, Easterseals is committed to the health and wellness of the more than 1.4 million people it serves every year.” They offer everything from inclusive child care and medical rehabilitation for young children with autism to job training, coaching, and placement for adults with disabilities, including veterans.
- Delaware Mud Run: The Mud Run is a boot camp–style race with obstacles that mainly involve mud. All proceeds of these events go to the Leukemia Research Foundation of Delaware.
We are thankful that we have been able to give back in these ways. To learn more about the services we offer in your location, contact SUI today. We are ready to bring our years of experience and community spirit to your project.
