Commercial HVAC units are heavy-duty machines that work round the clock to produce a comfortable environment, especially during the summer months. However, more often than not, these machines come across some problems that are not only frustrating but also hurt the business. It’s best to get help from commercial AC repair services but to increase awareness, let’s discuss some common commercial HVAC problems and how you can troubleshoot them.
HVAC Not Producing Cool Air
One of the most common problems with commercial HVAC is that they stop throwing cool air all of a sudden. There could be several reasons contributing to the issue. The first thing you need to check is the air filters. Air filters are designed to purify the air and need cleaning and replacement after a certain period of time.
That said, if the air filters tend to be clogged, the HVAC unit will struggle with airflow as well let alone produce cool air. Consult the user’s manual to go through the manufacturer’s recommendations regarding air filter replacement.
If it isn’t the air filter that is causing the problem, you should check the unit for leaking refrigerant. If the refrigerant is leaking, the compressor will utilize more electricity to compensate for the loss of cool air. However, it will put a significant amount of stress on the entire unit, which can lead to expensive replacements.
HVAC Producing Unusual Noise
Even though HVAC units hardly produce any noise other than the usual humming sound while functioning but during the off-season, several different types of creatures can take accommodation in the air vents or inside the unit that can produce certain types of noises.
In addition to that, if the unit is not regularly maintained, it could be that debris, dead shrubs, and leaves have made their way inside the unit and are coming in contact with the fan blades or other vital components. It could also be that the bearings are about to wear out. The fan motor has bearings that last several years before needing replacement. Therefore, in such cases, you will need to consult a professional who can diagnose the issue and replace the noisy parts, if needed.
HVAC Airflow Is Not Sufficient
HVAC units produce a sufficient amount of airflow to keep commercial restaurants and other areas pretty cool and comfortable. However, if you notice that the airflow has suddenly decreased, it means there is something blocking it. In most cases, it is usually clogged air filters.
Clogged air filters do not allow the air to pass through freely and restrict its passage. As a result, the HVAC unit struggles to produce the right amount of airflow. Try cleaning the air filter to see if the problem resolves. If it does not, you will need to replace the air filter. But even if that does not work, it means there is something wrong with the blower motor.
HVAC Is Unresponsive
Sometimes, commercial HVAC units simply fail to respond. In most cases, the culprit is the thermostat. The majority of the modern programmable thermostats run on batteries and if the batteries run down, the thermostat will not be able to properly communicate with the unit. That said, check the screen of the thermostat. If it is blank, it means it needs new batteries.
However, if the thermostat does not turn on, it means the thermostat itself is faulty and will need to be replaced. Moreover, a tripped circuit breaker could also cause the HVAC to shut down and not respond. You should check the circuit breaker for a blown fuse and try replacing it.
Circuit breakers trip when there is a surge in the electric supply. This is a sort of safety feature that cuts down the power to the electrical components saving them from burning. However, if the circuit breaker is constantly experiencing problems, you will need to hire a professional to solve the issue.
In the end, troubleshooting commercial HVAC problems can be quite tricky and easy at the same time. However, when it comes to the essential parts such as the HVAC compressor or condenser, you should always consult commercial HVAC companies Stony Brook. HVAC units utilize electricity to run and can lead to serious injuries or expensive replacements if you experiment with them.
