Common Commercial HVAC Repairs Property Owners Should Know During Summer

As a property owner, it’s essential to maintain your commercial HVAC system to ensure smooth operation throughout the year. However, during the summer, the system works harder than usual, leading to more wear and tear. This makes it crucial to know the most common commercial HVAC repairs you may encounter during summer.


Dirty Air Filters

Dirty air filters are a common issue that property owners face during summer. The air filters tend to clog up faster as the HVAC system works harder to cool the space. In addition, if the air filters are left unattended, they can cause the system to overwork, leading to refrigerant leaks. The first sign of a dirty air filter is reduced airflow, poor indoor air quality, and reduced energy efficiency. Therefore, it is critical to schedule regular HVAC maintenance to ensure the air filters get cleaned or replaced.

Low Refrigerant Levels

The refrigerant is a critical component of the HVAC system that absorbs heat from the indoor air to cool it. However, the refrigerant levels can drop due to refrigerant leaks, leading to the system malfunctioning. Low refrigerant levels cause the HVAC system to overwork, which results in reduced cooling capacity and high energy bills. If you notice a lack of cool air or ice accumulation on the evaporator coils, low refrigerant levels may be the cause. Reach out to commercial HVAC experts to diagnose and repair the issue.

Malfunctioning Thermostats

Since the thermostat controls the HVAC system’s temperature settings, a malfunctioning one can cause significant discomfort and energy wastage. In addition, if the thermostat isn’t accurate or completely stops working, it can cause the system to operate inefficiently or not at all. The leading cause of thermostat issues is faulty wiring, dead batteries, or thermostat aging. Property owners can avoid such problems by investing in intelligent thermostats or regularly maintaining their current thermostats.

Clogged Condenser and Evaporator Coils

A clogged condenser or evaporator coil is another familiar issue property owners face in summer. Since the HVAC system works overtime to cool the indoor air, the outdoor unit’s condenser coils can collect dirt, dust, and debris. This buildup can cause the condenser coils to malfunction, which reduces the system’s cooling capacity and energy efficiency. Similarly, the evaporator coils can also collect dirt and dust, which can cause the HVAC system to malfunction. Schedule periodic cleaning and maintenance of the HVAC system to avoid these issues.

Electrical Issues

Lastly, electrical issues can cause the HVAC system to malfunction. Electrical problems, such as damaged wiring, blown fuses, and tripped breakers, can cause the system to shut down completely. If the HVAC system stops working, it’s crucial to call an experienced commercial HVAC company to diagnose and repair the electrical issues.


Property owners must maintain their commercial HVAC systems to ensure they operate efficiently throughout the summer. Property owners can schedule preventive maintenance, diagnose issues early, and avoid costly repairs by knowing the most common commercial HVAC repairs. If you notice any of the issues mentioned above, don’t hesitate to contact commercial HVAC experts to fix the problems and keep your commercial space comfortable, safe, and energy-efficient.
