Accessibility

Whenever you think of installing the roof-mounted air conditioner, you should always think of the accessibility factor. This is crucial, although most people tend to forget it, thus leaving it out.

Note that your air conditioner will require a regular maintenance schedule. This means that the AC system should be installed in an easily accessed position.

Remember that you will always be forced to climb to the top of the roof with the rooftop air conditioner. Therefore, to be safe, the system should be installed in a simple position on the rooftop where you can easily reach it without much hassle. This will also contribute to the well-being of the entire system and its performance.

Climate

It is critical to understand that different areas have different climatic conditions. The roof-mounted air conditioner is designed to withstand harsh weather conditioners.

When installing the AC system, you should evaluate the weather condition of your area and understand what you need to put in place for the system to work efficiently.

Note that when the roof-mounted air conditioner is installed, it calls for maximum protection to work correctly regardless of the weather condition. You should always analyze the climatic conditioner within your region to detect the kind of protection that the AC system deserves to work effectively.

Components of The Roof Mounted Air Conditioning Unit

The roof-installed air conditioner is assembled in various serviceable housing where every component is installed independently. Note that every part of the AC system is installed separately to generate the desired results.

The AC system parts include the condenser, evaporator, receiver, drain pans, check valves, condenser fan, and vibration eliminators.

Whenever you are looking for a new system or a system to replace the old one, you should go for an energy-efficient design. Note that the new designs on the market have better designs and high efficiency. Better designs are a good energy saver, thus saving you from skyrocketing electricity bills.

However, the cost of the AC system with a better design is relatively high compared to the old-fashioned systems that were initially on the market. Even though the initial price of the modern AC system is high, it will save you from extra costs in the long run.

Air Control

The roof-mounted air conditioners have an air control system with dampers controlled automatically by the system itself. However, certain types of dampers need to be controlled manually, known as fresh air intake dampers. Also, there are specific sensors that have the responsibility to detect the temperature of the air.

The entire air conditioner system is designed to allow the damper’s opening depending on the unit settings and feedback of the sensors. Based on the system’s design, an off-the-shelf economizer mechanism can be applied to control the airflow.

The air already conditioned by the system is then channeled to different building parts through the duct distribution channel.

The diffusers are responsible for discharging the refined air into different rooms across the building. The individual thermostats control the amount of air that is already conditioned and released into the rooms.

Maintenance Hacks of the Rooftop Air Conditioner

Maintenance Hacks of the Rooftop Air Conditioner

Since the air conditioner is installed at the top of the roof, it is vital to consider various precautions to enhance the AC unit’s well-being and your safety during maintenance or troubling shooting the system. Do you understand some of these maintenance hacks? Don’t worry! Let’s dive in!

The panels are made of metal and are usually extremely hot when exposed to high temperatures. When there is direct sunlight and the weather condition is extremely high, use hand gloves when handling the heated panels.

Acquire a hat and sunglasses to cut short the fluid loss from your body due to high temperatures. Also, have a bottle of water to replenish your body.

The fumes generated from the system are incredibly harmful to your health. Therefore, you need a high level of protection to avoid inhaling the fumes. Note that it is always not advised to work on the maintenance of the AC system alone. Having a team of experts to work on the unit is always necessary to prevent any form of untoward incident.

When there are strong winds, you should always ensure that the system’s doors are secured. It aids in ensuring that the wind does not swing the panel to prevent injury. If you live in areas with strong winds, you should consider putting up wind shelters to be on the safe side.

When climbing to the top of the roof, you should have a reliable ladder that is strong enough for safety reasons. When climbing on top, you should always use all your hands to be on the safe side. This will help you to concentrate and remain comfortable.
