Rooftop HVAC units offer several advantages for commercial buildings. Their rooftop location frees up valuable interior space, reduces noise pollution, and allows for discreet maintenance, minimizing disruptions to daily operations. However, like any HVAC system, they can encounter common issues, including:

Dirty Coils

Rooftop HVAC units have coils that are exposed to the outside air, which can accumulate dirt and debris. This buildup can reduce the coils ability to absorb or release heat, making your unit less efficient and driving up energy costs. In some cases, dirty evaporator coils can even freeze, causing major problems. That’s why regular maintenance is essential to keep your unit running smoothly and efficiently. 

Refrigerant Leaks 

Over time, the copper pipes in rooftop HVAC units can corrode and leak refrigerant. If your unit is nearing the end of its lifespan, it may be more cost-effective to replace it rather than repair multiple leaks. However, for newer units, technicians can usually seal the leaks and recharge the system.

Faulty Blower 

A rooftop unit’s blower fan may begin running nonstop instead of cycling off at certain intervals if there’s a problem with the thermostat, relay, or limit switch.

Electrical Problems 

Rooftop units use a lot of electricity to power the fan and compressor. Electrical problems can sometimes cause the unit to trip the circuit breaker. If your building is experiencing frequent circuit breaker trips, it’s a good idea to have a technician check the rooftop units for electrical shorts, clogged air filters, or other issues that might be causing an overload.
