Common Repair Problems with Commercial HVAC Systems

The equipment for light commercial HVAC systems is more durable and sturdier than those found in homes… but that doesn’t mean they will experience any fewer repair issues. Commercial air conditioners, heaters, and packaged units must undergo much more stress than residential comfort systems, and that means they will need occasional service from trained experts.

Whenever you experience issues with your business’ heating or cooling system, contact DuAll Heating & Cooling for the service that will restore your workplace to the level of comfort your employees need and your customers/clients expect. We handle light commercial HVAC repair in Naperville, IL.

Here are a few common problems with commercial HVAC systems that our technicians encounter on the job:

Damage to the fan

The majority of commercial comfort systems are rooftop packaged units: all the components are housed in a single cabinet kept on the roof. Although the roof offers a large amount of isolation and therefore protection for the unit, it also exposes it to the elements. Debris can sometimes infiltrate the cabinet and cause damage to the large fans necessary for the heat exchange cycle. Loss of the fans will affect heating and cooling within the building and will require professional repairs.

Thermostat troubles

Even light commercial HVAC systems can use a complex series of thermostats and controls, far more intricate than those found in homes. Businesses frequently have zone control systems set up to allow different temperatures in different parts of the workplace, and errors with the thermostats can cause zones to lose conditioned air. It takes experienced commercial repair technicians to track down and figure out thermostat problems.

Insufficient heating/cooling

If air is blowing out of the vents, but it isn’t the expected temperature (room temperature instead of cooling or heating), you’ll soon start to hear complaints about it. The trouble may be in the thermostat, but it’s more likely a problem within the rooftop unit, such as a leak in refrigerant. If the rooftop unit is a heat pump, the problem could be a broken reversing valve, which will prevent the system changing form one mode to another.
