Getting Your HVAC System Ready for Cooling Season: Critical Equipment and Maintenance Checklist

As we transition from heating to cooling season, it’s essential to ensure that your HVAC system is prepared to handle the upcoming demands of warmer weather. One crucial aspect of this preparation is servicing key equipment to maintain efficiency, reliability, and longevity. Let’s discuss the critical equipment that should be serviced and why it’s essential.

Cooling Towers:

Cooling towers play a vital role in the heat exchange process of air conditioning systems. Neglecting their maintenance can lead to reduced efficiency and performance issues. Regular servicing of cooling towers includes cleaning air inlets, flushing cold water basins, inspecting water distribution systems, and ensuring proper fan and pump operation. By servicing cooling towers, you can prevent clogging, corrosion, and other issues that can hinder their performance, ultimately optimizing your cooling system’s efficiency.


Chillers are the workhorses of HVAC systems, responsible for cooling processes by removing heat from a liquid via a vapor-compression or absorption refrigeration cycle. Servicing chillers involves clearing away dirt and debris, cleaning condenser coils and intake filters, checking for leaks, and inspecting panels and steelwork for corrosion. Regular maintenance of chillers ensures efficient heat exchange, reduces energy consumption, and extends the lifespan of the equipment, ultimately saving you time and money in the long run.

AHU/AC Units:

Air Handling Units (AHUs) and Air Conditioning (AC) units are essential components of HVAC systems that require regular maintenance to ensure proper operation. Servicing these units involves inspecting condensate pumps, drain pans, and drain lines to prevent overflow, leaks, and mold growth. Addressing these issues promptly can prevent water damage, maintain indoor air quality, and prolong the life of your HVAC system.

Condenser and Chilled Water Pumps:

Condenser and chilled water pumps play critical roles in circulating water within HVAC systems, aiding in heat exchange and temperature regulation. Regular maintenance of these pumps involves ensuring proper drainage or pumping of condensate water, inspecting for leaks, and maintaining centrifugal pumps. By servicing condenser and chilled water pumps, you can prevent costly water damage, maintain system efficiency, and ensure uninterrupted operation of your HVAC system.

BMS Controls:

Building Management Systems (BMS) are advanced control systems used to manage and monitor various building systems, including HVAC. Servicing BMS controls involves performing a sequence of operation checks to optimize cooling plant performance, reduce energy consumption, and improve occupant comfort and safety. By regularly maintaining BMS controls, you can ensure the efficient operation of your HVAC system and identify opportunities for optimization and energy savings.

Servicing critical HVAC equipment is essential for ensuring the efficient operation, reliability, and longevity of your cooling system. By following a comprehensive maintenance checklist and addressing any issues promptly, you can optimize system performance, reduce energy consumption, and ensure the comfort and safety of building occupants. Don’t wait until the heat of summer arrives – schedule your HVAC maintenance today and stay ahead of the curve.
