Rooftop Mechanical Units & How to Maintain Them
Roof damage is a major source of property loss each year when buildings are subjected to high winds, wind-driven rain, hail, ice and snow, and wildfire. A compromised roof can lead to significant damage to internal fixtures, furniture, and equipment. Proper attention to all aspects of a roof can make the difference between minimal damage and catastrophic failure during high winds. To help business owners maintain roof issues, we have have produced a short checklist to help with the maintenance and repair of commercial roofs.

1-Air Filters and Outdoor Inlet Screens
Air filters require inspection every three to four weeks in order to see if they need replacement or cleaning. When air filters are dirty in any way, they disrupt the airflow that can make a system less effective. In extreme cases, they may be completely compromised.
Dirty filters mean that the air conditioner consumes more energy compared to the air conditioners with clean air filters, which may increase the electric bill. Screen inlets also require cleaning at least once every year.
Examine the motor and the area where the blower wheel is located. They are important components that have to be checked and cleaned in order to ensure that clean air is being pumped into the building.
Dirty wheels of the blower can damage the motor, which can destroy and unbalance the motor. If a unit is too noisy or making a lot of noise, it means that the blower wheel needs a thorough check-up.
When indoor and outdoor coils become dirty, they do not transfer the heat efficiently, which results in an increased operating temperature. It also puts more pressure on the unit.
Alongside, it reduces the airflow through the condenser coil. Therefore, it is necessary to inspect the outdoor and indoor coils. Regular soap and water can be used to clean the dirty coils. An evaporator cleaner can also be used for intense cleaning.
Examine the heat exchanger, as it can be polluted with gases, rusts or cracks hence, polluting the airflow going into the building. This includes checking the gas, heat, burner, igniter, and the combustion section. Vibrating sounds, popping or roaring are signs associated with ignition issues.
5-Condensation from HVAC Systems
Condensation can increase the ponding water that is localized in the units. This may result in damaging a commercial roof of a flat. The moisture from the condensation causes vegetation and mold to develop. Airborne debris may also be created, which leads to ugly stains. Use a product that is designed to prevent ponding waters.
