Dubai’s scorching heat puts a lot of strain on rooftop units (RTUs), and regular maintenance is essential to keep your space comfortable. Neglecting your outer unit can lead to costly repairs and breakdowns, leaving you sweating it out. Ignoring proper maintenance can lead to inefficiency, expensive repairs, and unexpected breakdowns. This guide offers a comprehensive checklist for rooftop unit maintenance, ensuring your system stays in top condition. These practices will maintain the effectiveness of your outro, whether you are the property manager or owner.
Pre-Maintenance Preparation
It’s crucial to adequately prepare before beginning the rooftop unit maintenance procedure. First and foremost, ensure your safety. Before starting any work, turn off your RTU and wear safety glasses and gloves. If you need more knowledge about it, hire an expert. If you are confident, make sure you have screwdrivers and a multimeter on hand, along with any replacement components that you may need.

It is the checklist for the upkeep of your rooftop unit. What if we add details as well, so you may go for it personally but follow the pre-maintenance preparations?
Visual Inspection
Now that you’re ready, let’s begin by giving your RTU a visual check. Start by examining the unit’s outside. Keep an eye out for any indications of physical damage, including cracks or dents, since these might point to an issue. Additionally, make sure the area around the unit is clear of any material that might impede airflow or harm it, such as leaves or dirt.
Next, examine the internal parts for any wear or damage, focusing on electrical connections and wiring. Address loose or frayed cables immediately, as they can lead to serious issues. In addition, examine the belts, pulleys, and fans closely as well.
Filter Replacement
Replacing the air filters is one of the easiest yet most crucial AC maintenance procedures. Filters may easily become clogged in Dubai’s dusty air, which can lower system performance and lower indoor air quality. Clean filters are crucial for maintaining proper airflow and ensuring the unit operates efficiently.
Filter replacement is an easy procedure. The old filter should first be removed from the filter chamber and disposed of appropriately. After that, carefully install the new filters, ensuring they are aligned. Replacing filters regularly prolongs the life of your RTU and enhances its efficiency.
Cleaning The Coils
The coils’ capacity to transport heat might be diminished over time if debris and dust build up on them. Reduced cooling effectiveness and increased energy costs may result from this.
Start with cleaning the unit’s external condenser coils. A coil cleaner or a solution of water and mild detergent can remove the dirt. Make sure to thoroughly rinse the coils after cleaning to remove any remaining residue.
Proceed to the evaporator coils, which are located inside the unit, next. Because of their placement, cleaning these coils might be more difficult, but you must remove all dirt and filth from them.
Electrical Component Check
As the foundation of your RTU, electrical components need to be inspected often. Examine the wiring and connections first. Make sure every connection is tight and secure since unsecured connections may result in fire dangers or other electrical problems.
Other essential components to check are contactors and capacitors. The unit’s contactors switch it on and off, while capacitors store and release energy to power the motors. Look for signs of wear, such as burning or pitting on the contactors and bulging or leaks in the capacitors. When necessary, replacing these parts helps save bigger, more expensive problems later on.
Airflow Inspection
Proper ventilation is essential for your system to operate efficiently. Examine the ductwork that is connected to the unit first. Examine any damage, obstructions, or leaks that could impede airflow. You can keep your building’s temperature control consistent by making sure the ducting is in good shape.
Next, inspect the blower motor and fan. Look for any debris or damage on the fan blades that could be preventing them from working properly. Furthermore, confirm that the blower motor is running smoothly. If you hear unusual noises or the motor feels excessively hot, it might need additional lubrication or replacement.
Refrigerant Level Check
Proper refrigerant levels are crucial for your RTU’s efficiency. Your unit won’t be able to cool efficiently if the refrigerant level is too low, which will result in greater energy costs and use. Conversely, an excessive amount of refrigerant may result in pressure problems and harm the device.
If you’re unsure about checking the refrigerant levels, it’s best to consult a professional, as it requires specific tools and expertise. If you discover that the refrigerant levels are wrong, you should take prompt action to prevent further damage. This might be a sign of a leak.
Thermostat Calibration
Since your thermostat serves as the main control panel, it must be exact. An inaccurately adjusted thermostat may cause your unit to work harder than it needs to, increasing wear and tear and raising your energy costs. Begin by comparing the temperature shown on your thermostat with a reliable thermometer placed nearby to calibrate it. Follow the manufacturer’s instructions to modify the thermostat settings if there is a noticeable change.
Final System Test
After completing all the rooftop unit maintenance steps, it’s time to power up your device and test the system. To begin, reactivate the device and allow it to operate for several minutes. Keep a close eye on how the system functions. Make sure the temperature is being adjusted properly, listen for any strange noises, and inspect the ventilation.
If everything seems to be working well, congratulations! Your RTU is prepared to provide pleasant and cool air in your building. But if you find any problems, it might be worthwhile to go over the checklist again or contact an expert for a more thorough examination.
Maintenance Log
Updating a thorough maintenance diary is one of the recommended practices for RTU upkeep. Document all maintenance activities, including dates, tasks completed, and any issues found, to keep track of the unit’s condition over time. If you need to review earlier maintenance tasks or if an expert technician wants to inspect the machine, this log is helpful.
Conclusion
Rooftop unit maintenance doesn’t have to be a difficult undertaking. You can make sure your RTU runs well and avoid unplanned breakdowns, especially in Dubai’s harsh environment, according to this preventative maintenance routine. Frequent maintenance makes your interior environment safe and comfortable, in addition to extending the life of your unit. Though you can complete some of these activities by yourself, if you have any questions, feel free to contact an expert like VAC Technical Services.
