Maintaining commercial HVAC systems is essential for ensuring a comfortable and safe environment for customers, employees, and other occupants. It’s important to regularly inspect and clean the unit, replace any parts as needed, and make sure all components are functioning correctly. In this article, you will learn how to properly maintain HVAC commercial systems. Keep reading to learn more.

Find a qualified technician to perform regular inspections.

To ensure maximum efficiency and comfort levels, regular inspections of all components of the system should be performed by a qualified technician. This includes checking for air filter obstructions or leaks, evaluating refrigerant levels for accuracy, inspecting electrical connections for safety risks, monitoring ventilation performance, and verifying thermostat settings are correct. Taking steps to prevent problems from occurring before they happen can help keep your business’s equipment running at peak efficiency and reduce costly repairs down the line.

Switch out dirty air filters.

In addition to regular inspections from an experienced technician, regularly changing out filters is another important step when it comes to maintaining an HVAC system. Dirty air filters can greatly decrease airflow throughout the entire unit resulting in decreased cooling capacity as well as higher energy bills due to increased fan motor usage which consumes more electricity than usual. Filters should be changed at least once every three months or on a manufacturer’s suggested schedule based on usage rates. Depending on how often you use your system, you may need more frequent replacements if dust buildup occurs quickly in your space.

Schedule preventive maintenance services.

Scheduling preventive maintenance services with a trusted professional team can go a long way in helping maintain optimal performance from your HVAC systems over time while extending their lifespan, too! Preventive maintenance involves cleaning coils, lubricating moving parts like fan motors and blower wheels, as well as checking other components within the unit. This includes belts and pulleys that could become frayed or worn down over time causing premature breakdowns if left unaddressed. Getting these serviced annually will help keep them running smoothly so they don’t turn into larger issues later down the road.

Examine refrigerant lines for signs of wear or corrosion.

When examining refrigerant lines for signs of wear or corrosion, it is important to be aware of the potential hazards associated with handling potentially hazardous materials. These lines are typically made from copper, aluminum, steel, or plastic and can corrode over time due to exposure to moisture and other contaminants in the air. Corrosion can adversely affect the efficiency of your HVAC system by reducing its ability to transfer heat efficiently. Additionally, a leaking line could pose both a health hazard and an environmental hazard. To inspect for signs of wear or corrosion, you will need safety equipment including gloves and eye protection plus proper ventilation in the work area. If this task seems daunting, then a technician can do it on your behalf.

Clean and tighten all connections and flanges.


Maintaining HVAC systems involves cleaning and tightening all connections and flanges. This is a crucial step in order to ensure that the system operates safely, efficiently, and reliably. Connections include any pipes or cables used for the power supply or energy distribution between equipment components. Flanges are metal plates or rings with holes drilled into them which connect two pieces of piping together. Cleaning these elements means removing dirt, dust, debris, rust, and other contaminants from them before they are tightened down so they make good contact when connected. Tightening these connections also helps prevent leaks by ensuring that the connection points make secure contact with one another.

Overall, regular maintenance of commercial systems is essential to ensure safe, efficient, and cost-effective operations. Proper maintenance of these systems can help to reduce unexpected breakdowns, extend the life of the system, and improve indoor air quality. Taking the time to regularly inspect, clean, and service HVAC systems can save businesses a great deal of money in the long run.
