Three things to check on your HVAC cooling tower

Posted on

The cooling tower is an essential part of your HVAC system. When your HVAC system is operating correctly, it will ensure that the temperature in your home or office remains at exactly the right level whatever conditions may be like outside. However, when the HVAC system fails, then you will soon notice the difference as the conditions inside the building begin to resemble those in the open air. One of the biggest causes of HVAC failure is problems with your cooling tower often leading to an expensive cooling tower repair.

Understanding where problems can develop in your cooling tower can help to keep your HVAC system in better repair and avoid the need for a cooling tower repair.

Why are cooling towers the cause of so many problems?

Part of the reason that cooling towers can fail is that they are generally the unseen part of your HVAC system. Instead of being in plain sight, they are frequently hidden on the roof or somewhere else that you can't see them, and this can lead to an 'out of sight, out of mind' mentality. When you also recall that cooling towers are usually built from galvanised steel and will suffer from the effects of a corrosive environment generated by hot air, water and chemicals, it's no surprise that neglect will often need a cooling tower repair.

Here are three things to check so that you avoid the need for an expensive cooling tower repair.

A corroded tower

Due to the corrosive environment inside the cooling tower, it's not uncommon to find metal wastage and or holes occurring even when the metal has been galvanised. Corrosion will lead to unreliable system operation and exposure of other parts of the HVAC system. Identifying corrosion at an early stage is essential to keep your HVAC system working effectively.

Damaged fan blades

Impingement from both dust and moisture can have a negative effect on the fan blades leading to corrosion and erosion. At first, this damage will simply make your system less efficient, but if the damage is allowed to continue, the blades may need to be replaced.

Leaking pipelines

Pipelines connecting the cooling tower to the rest of your HVAC system can be a constant source of concern. They are subject to the same corrosion issues which can affect the cooling tower but in addition, leaks can occur as the pipes move in relation to the cooling tower.

Checking on these three things will allow you to avoid a cooling tower repair or to minimise the damage caused if a repair is needed. For more information, speak with a cooling tower repair professional.
