The HVAC system in your commercial building is incredibly important to the functioning of your building. You need to be sure that it’s working at its best at all times.
An HVAC RTU is one of the most essential parts, and it needs to be monitored and maintained often. But what happens to an HVAC RTU as time passes?
There are a few common issues that can occur that cause your system to break down often. There may be issues if you find that your RTU is becoming more and more unreliable.
Don’t let this get out of hand; read on to find out what might be causing the problem.
Refrigerant Leaks
Refrigerant leaks can occur in any part of the system. This is due to corrosion, poor installation, and rough handling.
This can lead to poor energy efficiency and poor performance. In some cases, it can also damage the rooftop HVAC unit itself. Refrigerant leaks should be addressed immediately to avoid further damage and expense.
Regular maintenance and occasional inspection of the HVAC unit can help to prevent or identify any potential problems before they become too serious. Ensuring that all components are functioning properly will help to prevent costly RTU repairs in the future.
Defective Thermostat and Controls
One of the most common problems is an inaccurate or non-working thermostat, which can cause incorrect or no response when adjusting the settings. If the thermostat is electronic, the wires connecting it to the RTU’s control systems may have come loose or shorted out. It is also possible the control panel or circuit board that regulates the temperature of the RTU may need calibration or have a faulty part.
If any of these common problems arise in high buildings or hard-to-reach places, it is best to call HVAC services for rooftop units. These professional services will help to resolve the issue in a timely and cost-effective manner. They can ensure that the system is running at its peak performance and that the building and its occupants are safe and comfortable.
Dirty Air Filter
Common issues associated with Heating, Ventilation, and Air Conditioning (HVAC) Rooftop Units (RTU) are related to inadequate filtration and a decrease in energy efficiency. Improper or dirty air filters can lead to restricted airflow, increased operating costs, and may worsen indoor air quality. Furthermore, dirty filters can cause dust and other particles to enter the system and, if left unchecked, can cause excessive wear and tear impact on the HVAC’s components, leading to system failure.
Frozen Coils
Common issues with an HVAC RTU can include frozen coils. This occurs when air is unable to circulate through the unit, leading to ice forming in the coils. This restricts airflow and can result in poor air quality, as well as inefficient cooling.
Additionally, frozen coils create added wear and tear on the RTU. As the problem persists, major issues with the compressor, electrical connections, or safety controls can occur.
Ensure Your HVAC RTU is in a Good Condition
In conclusion, common HVAC RTU issues are important to find and fix properly. Ignoring a problem leads to a higher repair bill and potential system failure. For help troubleshooting HVAC RTU problems and efficient repair, contact your local HVAC contractor today.
