AHU Services: Signs Your AHU Motor Requires Immediate Replacement
01 June 2023Air handling unit or AHU motor may require an urgent replacement service from a professional technician if it already overheats, vibrates excessively, consumes more energy, and others.
Buildings these days maximise AHU to regulate the circulation and quality of air within the said buildings. It is a part of the heating, ventilation, and air conditioning or HVAC system, which is intended to provide cool or warm air to the building. AHU works by filtering the air drawn into the system, heating or cooling the air, adding or removing moisture from the air, and distributing the conditioned air throughout the building. These functions are possible thanks to its motor.
The AHU motor helps circulate air through the HVAC system. Now, if your AHU unit manifests the following signs, you may have to replace its motor immediately.
Reduced Airflow
The AHU motor works by moving air through the system. However, if you notice reduced airflow coming from your vents, it only means that your AHU motor is failing. Your motor may have already failed due to worn or damaged fan blades. It may likewise simply be unable to generate enough power to move the air properly. Failure to replace your motor due to reduced airflow may lead to poor indoor air quality, increased energy costs, and other problems.
Overheating
If your AHU motor is running hot to the touch or emitting a burning smell, it may be overheating. This issue may be due to a variety of factors like a malfunctioning cooling system, clogged air filters, or an electrical issue. If left unchecked, overheating can cause serious damage to the motor and other parts of the HVAC system. It could even pose a fire hazard.
Strange Noises
Your AHU is expected to work silently during your business operations. But if you hear unusual noises like grinding or banging sounds coming from this unit, it may be a sign that the motor is malfunctioning. These noises may be caused by worn bearings, damaged blades, or other internal problems with the motor. Ignoring these noises could lead to more serious issues down the line, which is why you must address them promptly.
Excessive Vibration
If you notice excessive vibration or shaking coming from your AHU, it could indicate that the motor is unbalanced or has loose components. It could cause damage to the motor itself or other parts of the HVAC system. It can even lead to a safety hazard if left unchecked. A professional technician must inspect the motor and determine whether it needs to be replaced.
High Energy Costs
A sudden spike in your energy bills may only mean that your AHU motor has become inefficient. A motor that struggles to keep up with your building demand will require more energy to operate, which leads to higher costs for you. Replacing the motor with a more energy-efficient model can reduce your energy bills and save you money over time.
An AHU motor is a critical component of your HVAC system. Once it shows signs of failure, you must address its issues promptly by reaching out to a professional technician, who can inspect your motor and determine whether an urgent replacement is required.
