Commercial Air Conditioning – Possible Reasons for Furnace Decline

With Australia's cold season fast approaching, now is the time to ensure that your commercial air conditioning is in tiptop condition. Since HVAC units are primarily used for cooling for most times of the year, problems with the electrical furnace tend to go undetected until the last possible minute, and this can translate into utter discomfort for your employees. Fortunately, detecting signs of trouble in good time gives you the opportunity to address them before autumn and winter are in full swing. If your commercial air conditioning system's furnace seems to be working wonky, here are some possible reasons for its decline.

The furnace filter has developed blockages

A typical culprit for furnace related HVAC problems is clogging that has been left to go on unencumbered. Property owners usually do not realise that even with the meticulous cleaning of the premises, dust and grime still builds up in the filter as it catches airborne particles when ventilating the office. So when the filter is not attended to for an extended time, its efficiency steadily begins to decline, which will impede on the furnace's functionality too. Not only will you notice that the warm air circulated in your office is inadequate, but the quality of air will also be inferior. An HVAC specialist can clean out the furnace filters plus your air conditioning vents to enhance the overall efficiency of your system.

The blower motor has a compromised fuse

The second possible reason why the furnace of your commercial HVAC unit may not be at optimum is if the blower motor is damaged. For the blower motor to operate, it needs a functional fuse. Hence, a blown a fuse means that the entire furnace will not be able to run. This fuse becomes at risk of blowing when the blower motors are overworked. Because this overworking typically happens in the winter, you may not be aware of any structural problems with the motor until the cold season comes back around. It is, therefore, essential to have a technician examine the blower motor itself for any signs of wear. Any visible symptoms of harm should prompt you to replace the blower motor to prevent the component from succumbing to damage smack in the middle of the cold season.

The building has electrical problems

Electrical issues in your commercial property can hurt the operation of your HVAC's electrical furnace. The furnace is controlled by a myriad of switched, timers, controls and so on. For these components to work appropriately, they need the right electrical voltage. If your furnace is receiving too high a voltage, your entire furnace is at risk of shorting out. Conversely, low voltage means the furnace is not being furnished with enough power to function.
