While you can solve some HVAC issues by cleaning coils and filters, some other problems still need to be solved in the heating and cooling systems that will eventually cause much bigger issues.

Common Issues Faced by Commercial HVAC Systems

Commercial HVAC systems cover more areas than residential systems, so they have different maintenance requirements.

These systems expose various problems for the lack of maintenance for which business operations can’t be continued undisturbed. The difficulties will create bigger issues if you don’t take preventive measures immediately.

You must figure out those common commercial issues your HVAC systems face and their solutions. 

Why do I need Expert Solutions For Commercial HVAC System Issues

If you have the best HVAC contractor for your commercial HVAC system issues, they provide effective troubleshooting, minimize downtime, and maximize energy efficiency.

Common Commercial HVAC Issues 

Unusual Noises 

Unusual furnace noises are warning of mechanical issues. It indicates that the blower motor is malfunctioning. Therefore, you should replace the motor to avoid a furnace failure. Dirty burners and airflow issues cause some noises.

Dirty Filters

Dirty air filters are an excellent problem for an unhealthy commercial HVAC system. They restrict airflow and cause the unit to work harder than usual to circulate air.  

Thermostat Malfunctions

The furnace may not operate properly due to the malfunction in the thermostats. You must check the owner’s manual and review the instructions of operations to prevent unnecessary expensive repairs. 

Fuse Blown

Blown fuses have become a common commercial HVAC issue. This problem indicates that the blown fuse can no longer protect your compressor and motor from overheating. 

Burner’s Inefficiency 

Rust, dust, grime, debris, and other contaminants can build up on the heat exchangers, cause the burner’s inefficiency and damage the system. The reduced burner’s inefficiency makes the system work harder than usual, leading to high energy usage and higher electricity bills.

Compressor Leaks

You can identify the problems in your compressor when it starts running louder than usual. It will be a sign of a refrigerant leak. The compressor is an expensive component of your system that keeps heating and cooling processes in order. If the refrigerant gets low, the compressor operates disturbingly and causes overheating. 

The Ways to Resolve Commercial HVAC Issues 

Repair the Damaged Ducts

The ducts develop leaks from rodents and vibrations that will cause damage to the ducts over time. Additionally, damaged ducts also wash the system to work harder than needed. So, you must repair them immediately. 

Ensure Proper Ventilation 

Ventilation should always be a significant concern to get better air quality. Poor air quality is the result of dirt, water, or rodents. There are several needs you have to ensure to get an improved commercial HVAC system. So, give importance to proper ventilation besides proper installation.

Change the Dirty Filters

Without adequate airflow, your HVAC system will freeze over. So, you have to take the initiative before anything affects the compressor. Reduced airflow is the result of dirty air filters. You must contact a contractor to replace your dirty filters and clean the evaporator coils. 

Use Properly Sized Equipment 

There is no one-size-fits-all commercial HVAC system. You should choose the system based on need and size. Too small units can’t do their job correctly, and too big units will be wasteful. So you must plan adequately to determine the best fit. Proper size and equipment cut down electricity costs and increase the equipment’s lifespan. 


Your HVAC system is one of the essential pieces of equipment that should be inspected and maintained to prevent outages during extremely hot and cold months.
