The most common types of commercial HVAC systems are refrigerant-based. The rooftop units that often provide climate control for commercial facilities operate using powerful compressors that put the refrigerant under pressure so it circulates to move heat from one location to another—either heating or cooling the interior. The compressor is the most important component of these commercial HVAC systems: it draws on the most power and it serves as the literal heart of the system. A failed compressor is a serious problem since the cost of replacing one often makes it more cost-effective to replace the entire HVAC unit instead.
If you know what to watch for, you may be able to detect a compressor that’s starting to fail and call for professional repairs in time to stop a bigger problem. Below we’ll look at some of these warning signs of compressor trouble.

Chances are high that your commercial or industrial facility uses rooftop units in some capacity. Everything from a standard office building to a sheet metal factory has HVAC units housed on the roof to provide for proper environmental controls around the year.
Maintaining the proper climate inside a commercial facility with cooling units isn’t only something to worry about during the hot weather of summer. The heat created in facilities from the equipment inside them often requires cooling systems. For example, server room cooling is essential for most businesses, even small ones, and it’s necessary around the year.
