Winterizing Your HVAC Rooftop Units: Best Practices for Commercial Buildings in the Southeast

To maintain efficient and reliable heating and cooling throughout the cold season, it is crucial to winterize your commercial HVAC systems. While the Southeastern United States generally experiences milder winters than northern regions, temperatures can drop significantly during this time, so businesses in this area need to prepare their HVAC rooftop units accordingly.

Hoffman Mechanical Solutions understands the unique needs of commercial buildings and industrial facilities in the Southeast. We offer top-tier services to ensure your HVAC systems are winter-ready.

1. Insulation and Sealing Insulating and sealing your HVAC rooftop units is a primary step in winterizing your HVAC systems in the Southeast. It prevents heat loss and ensures that your system produces warm air in your building. Maintain a stable indoor temperature by sealing gaps around rooftop units, ductwork, and connections.

2. Professional Maintenance Preventing unexpected breakdowns during the winter season requires regular maintenance. In the Southeast, where HVAC units may not be as heavily used as in colder regions, these systems can be more susceptible to problems if not maintained properly. Hoffman Mechanical Solutions can provide professional maintenance services to inspect, clean, and tune your rooftop units.

3. Programmable Thermostats Consider upgrading to programmable thermostats for your rooftop units. This allows you to set the temperature to lower settings during off-hours, nights, and weekends when your building is less active. These thermostats can save on energy costs while still ensuring a comfortable indoor environment when needed. 4. Frozen Coil Prevention

In the Southeast, winter temperatures can occasionally drop below freezing, leading to frozen coils. Insulate the coil section and keep drain lines clear to prevent ice buildup. Regular maintenance checks by professionals can identify and address potential issues. 5. Weatherproofing

Wind and rain are common in the Southeast during the winter, so weatherproofing your rooftop units is critical. Ensure that your units are properly secured and consider installing windbreaks to protect them from extreme weather conditions.

6. Monitoring and Remote Control

Implement remote monitoring systems for your HVAC rooftop units. This technology allows you to keep track of your system's performance and adjust as needed, even from a distance. Hoffman Mechanical Solutions can help you set up and manage these systems. We specialize in a wide range of systems, including the Daikin Rebel with its MicroTech III Controller, and we can program the controller to work with units with constant volume (CAV) or variable volume (VAV) controls. For a comfortable indoor environment and to avoid unexpected breakdowns during colder months, you must winterize your HVAC rooftop units in the Southeast.
