Rooftop HVAC Units

Servicing rooftop HVAC units primarily depends on the usage, location, and manufacturer recommendations. Regular preventive maintenance should be performed at least twice a year, typically in spring and fall before the peak usage seasons. Scheduled maintenance can help identify potential problems early, ensure optimal efficiency and longevity, and prevent costly repairs or downtime.

Additional service may be necessary based on specific factors such as high usage, extreme weather conditions, or if the unit is subject to heavy dust and debris. Reactive services are also required when there are noticeable issues like inconsistent temperature control, unusual noises, or increased energy consumption. Scheduled and reactive services ensure that the units remain reliable and efficient throughout their lifespan.

The lifespan of rooftop HVAC units varies widely, generally ranging from 15 to 20 years. This depends on several factors including the quality of the initial installation, the unit's make and model, its usage patterns, and how well it is maintained over time. Regular servicing, quality repairs, and proper operation significantly extend a unit's lifecycle and efficiency.

However, even with diligent care, all units eventually reach a point where it becomes more cost-effective to replace rather than continually repair them. Proper end-of-life management, including professional removal and responsible disposal of old units, is an essential part of the lifecycle of rooftop HVAC systems.

Retrofitting existing rooftop HVAC systems is absolutely possible and often a practical solution for many businesses. Retrofitting involves upgrading your existing system with new, energy-efficient technology, which can significantly improve its performance, efficiency, and lifespan without the expense and disruption of a complete replacement.

Before proceeding with a retrofit, a thorough evaluation of the current system is crucial to determine its viability. Factors considered include the age, condition, capacity, and performance of the existing system, as well as business-specific needs such as future expansion plans or changes in heating and cooling requirements.

Common issues with unmaintained rooftop HVAC units include decreased performance due to wear and tear over time, clogged filters from dust and debris, refrigerant leaks, electrical problems, or fan motor failures. These problems can result in reduced comfort, increased energy consumption, unexpected breakdowns, or shortened equipment lifespan.

Regular professional maintenance can help prevent many of these issues by identifying and addressing them early. In cases where an issue is detected, prompt professional repair is vital. Waiting to address problems not only compromises the comfort of building occupants but can also lead to more complex, costly repairs down the line.
