Our team at PROAC Corporation understands how much of an inconvenience it is when your HVAC or building system suddenly stops working. If you are wondering why your HVAC system in your commercial building is not working, here are some main causes it could be failing. If you’re not sure what’s wrong, our team can help find the problem and prevent other issues from happening.
System Failure May Be Due To Clogged Evaporator and Condenser Coils
If your HVAC system stopped working, has weak airflow, or your energy bills seem to be rising, you should be checking your evaporator and condenser coils. In an HVAC system, the evaporator and condenser coils transfer heat in and out of your building. Over time, these coils can get clogged with dirt and dust and eventually restrict heat from transferring, forcing your HVAC system to work harder or even not at all.
Dirty and Clogged Air Filters Could Be The Cause
Not only do air filters improve air quality in your building by trapping various allergens, but it also protects internal components of your HVAC system. When your air filters are dirty or clogged, it can decrease airflow, which can cause your HVAC system to freeze up or overheat. Ensuring that your system has the correct filter size and regularly inspecting and cleaning the filter can prevent many HVAC system issues before they begin.
Dirty or Blocked Fans Lead To Building System Failure
In an HVAC system, the fans are what push conditioned air throughout your building. It is important to clean the fan blades of your system, whether you do it yourself or get it done professionally, because dust and debris can cause the fan to be unbalanced or blocked completely. This not only reduces airflow but can lead to motor strain or complete fan failure.
Building System Failure Due To A Fan Out of Balance With Motor in Your HVAC System
Unbalanced fans in an HVAC system can start excessively vibrating, causing the motor to be overworked. This can lead to uneven heating and cooling and potentially even your HVAC system to stop working completely.
Building System Failure Because Of Electrical Issues & Component Failures
Loose wires, failing capacitors, tripped breakers, or sensor malfunctions can all interrupt your building’s HVAC operation. These electrical issues often go unnoticed until they cause a complete system shutdown. Regular electrical maintenance and inspections can help you avoid unexpected outages to your system.
Thermostat Issues Connected to Your HVAC System May Be Responsible
Sometimes system issues are not related to the actual HVAC system, but it can be a thermostat or sensor issue. If a thermostat is misreading temperatures or failing to send the correct signal, your HVAC system may not be running when needed or even at all.
The Cause Could Be Drainage Or Condensate Line Problems
When condensate drain lines become clogged with algae or debris, water backs up into the system. Many commercial HVAC systems have float switches that automatically shut the system off to prevent water damage. If this is a problem for your HVAC system, it is a good idea to make sure it gets professionally cleaned.
Lack of Preventative Maintenance Causes Building System Failure
It’s easy to put off maintenance until something breaks. But many of these issues listed above can be prevented by routine inspections and cleanings. Give your commercial HVAC system more working years by getting your system professionally maintained by PROAC Corporation.
