Complete HVAC System Installations and Retrofits

From new construction to rehab projects, The Severn group understands how proper installation is crucial to an efficient and effective HVAC system. Even with the latest technology available, without high trained and experienced teams to make sure your equipment is running at peak performance, it can end up in long-term costs throughout the system’s life cycle. Our technically knowledgeable team uses their proven project management skills to ensure that every system is constructed on time, per specifications, and is operating efficiently from the start.

New Construction

The Severn Group has robust experience of installing thousands of commercial and industrial HVAC systems in the Washington D.C. metropolitan area. Our clients recognize the need for expert technicians that have proficient background in HVAC systems while having insight into new construction standards.

Our team of professionals is committed to, and have earned a reputation for outstanding work and safety standards. All of our foremen and supervisors are OSHA-30 certified and we are dedicated to having all field personnel OSHA-10 certified. Our foreman and supervisors are also First Aid and CPR trained and they are re-certified on an annual basis.


Just like new construction projects, similar adherence to factory installation and manufacturer standards is equally important on a rehab project. Retrofits or installations in a remodeling project have a whole unique set of obstacles to consider. With an increased drive toward more energy efficient HVAC systems, having a company with both design and installation experience is critical.

The Severn Group can repair any issue that may arise. Our certified technicians have years of experience, and are trained and certified in the nuances of evaluating and troubleshooting large-scale, multi-unit systems.

There may be a time when your commercial HVAC system needs a full replacement. In general, if your system is more than 10 years old, breaking down frequently, or causing comfort or noise issues inside the building, it’s best to consider replacing your commercial HVAC system.

When upgrading to a newer HVAC system, our technicians will work as quickly and as efficiently as possible to minimize the impact on your business. Newer systems are 20 to 40 percent more efficient, and do a better job of controlling temperature and humidity, which improves air quality.  Contact us if you’re considering replacing your HVAC system. We’ll provide you a quote that meets your budget and your needs.


Commercial HVAC systems have a lot of moving parts, and to that end, are similar to a car in that they need regular maintenance. Many HVAC manufacturers provide a limited warranty on their systems. However, one requirement of this warranty is that the HVAC system needs to be serviced regularly by a certified technician. Regular service records will back up your claim in the event that something breaks, allowing parts and labor to be covered under warranty.

Service contracts also ensure that your HVAC system will receive regularly scheduled maintenance on time every time, providing you with one less thing to worry about when running your business. In addition, regular service will ensure that your commercial HVAC system runs for its full intended lifespan, thereby sparing you the significant cost of replacing it before its scheduled end of life.

With every project, we not only help to ensure a lower cost of installation but a lower cost of operation throughout the system’s life cycle. Experience in design and planning allows our team to work within budget and deadlines effectively. Call us today to learn more on how we can add value to your project.
