You may know that an air conditioner runs using refrigerant. Refrigerant cycles through the entire system in order to remove heat from the inside air. And your commercial HVAC system must maintain a set level of refrigerant in order to properly do its job. Without the right level of refrigerant, your HVAC system can suffer a lot of damage and may even need replacement in some severe cases.
Your commercial HVAC system has kept your employees, tenants, customers, and/or clients comfortable throughout the years. But as the years go by, you may begin to wonder: when is it time to replace an older commercial HVAC system? Commercial heating and air conditioning systems are built tough to handle a large heating or cooling load, but they cannot last forever.
You’ve started to notice hot or cold spots in the office, and customers or employees have noticed as well. Maybe there are odd burning smells coming from the vents, or rattling noises from the rooftop units above. Whatever the signs, you think you have repair issues with the commercial HVAC system that makes a comfortable environment in your business. Who should you call?
The rooftop unit is the workhorse of the commercial HVAC world. Even people with no knowledge of how heating and cooling works for a commercial building know that the machines that keep the rooms throughout the structure comfortable are located on the roof.
In principle, commercial HVAC systems don’t differ in any significant way from residential HVAC systems. Both use constantly cycling refrigerant gas to lower the temperature of the air, which can then be blown through the space via a fan and a system of ducts.
