When properly installed and maintained, commercial HVAC is an essential component of a productive, efficient, and comfortable NYC office building. During periods prone to extreme temperatures like the summer and winter season, however, commercial NYC buildings may experience a number of dangerous problems that prevent temperature regulation throughout the building.

The Dangers of Commercial HVAC Problems

When your commercial HVAC system breaks down, it can cause major problems for you and your building occupants. It can also lead to safety hazards and expensive repairs down the line, especially if these problems aren’t resolved quickly enough. 

Below are the most common NYC commercial HVAC problems, along with their solutions:

Insufficient Heat

If your commercial HVAC system isn’t producing enough heat, the problem may be that the thermostat is set too low or in the wrong mode. Another common reason is a blown fuse or tripped circuit breaker. However, if these things are not the problem, then there may be an issue with your heating unit itself. In this case, emergency HVAC service should be performed by a professional as soon as possible to identify the source of the heating problem.

Insufficient Cooling

Conversely, if you are experiencing insufficient cooling throughout your NYC office building, check to make sure that the thermostat is set above room temperature and in cooling mode. If those controls are operational, the unit should be inspected for airflow quality and filter build-up. By frequently changing air filters, you can ensure your commercial HVAC system is running at peak performance throughout the year. 


This is usually caused by a malfunctioning motor or compressor – or a dirty condenser coil. If you’re lucky, overheating will simply lead to an increase in your power bills as the system struggles to work at full capacity. In some cases, however, overheating can cause serious damage to your electrical system, potentially leading to a fire hazard or even an electrical short that shuts down your entire building. In this scenario, a professional HVAC technician will need to inspect your system to identify the necessary repairs.

Frozen Coils

A frozen coil is often caused by a clogged filter or a leak in the refrigerant line. You’ll know you have this problem if ice forms on the outside of one of your units. It’s not something you should ignore – not only does it mean your system is operating at reduced efficiency, but as the ice melts, it can cause water damage inside your walls and floors (not to mention inside the unit itself).

The Benefits of Commercial HVAC Preventive Maintenance

If you’re a building owner or facilities manager, your New York City commercial HVAC system is an important investment.
