Common Rooftop Chiller ProblemsThe rooftop chiller on your commercial building serves HVAC systems by ensuring they deliver the proper humidity level, temperature, and ventilation while minimizing operating costs.

To keep your tenants comfortable and happy, your rooftop chiller must work properly at all times. Preventative maintenance is key to keeping them up and running. Still, you’ll need to repair even the most well-maintained rooftop chiller at some point.

If you experience any of the following, it may be time to service your rooftop chiller:

Uneven cooling or heating
Inconsistent airflow throughout the building
System efficiency loss
Unexpected high cooling or heating bills
Unfamiliar sounds
Poor indoor air quality

The staff at BMSI in Washington, D.C., are well qualified to work on your rooftop chiller and diagnose your system issues, which some common mishaps could cause.

Clogged or Dirty Filters

If you don’t replace your filters regularly, they can get clogged and filled with dirt, which can cause the HVAC system to work harder. Energy costs can increase, and over time, this can reduce the life of your system.

To make sure your HVAC system and rooftop chiller are performing optimally, replace your filters quarterly. Be sure to monitor them frequently to prevent clogged and dirty filters. It will also improve the air quality throughout the building by reducing allergens, dust, and other air pollutants from circulating.

Lack of Maintenance

If you don’t already have one in place, it’s time for a preventative maintenance plan. Regular checkups and service can keep minor HVAC problems from turning into major repair expenses, which can cause a system failure. Like the ones at BMSI in Washington, D.C., service technicians can identify and correct problems while performing routine maintenance to allow your HVAC equipment to perform as designed.

Leaking Refrigerant

The coils of the HVAC system contain refrigerant, which dehumidifies indoor air and cools each room. If the refrigerant is leaking, the HVAC cannot keep up with demand, producing air that is not cold. This makes the condenser work harder to compensate, which can cause more costly system issues. Suppose tenants are complaining about the building being hot despite the AC being on. In that case, you could have leaking refrigerant from your rooftop chiller.

Inconsistent Airflow

The dampers in the rooftop chiller control the airflow throughout the building. Suppose some rooms are heating or cooling faster than others. In that case, there could be improper air balance causing inconsistent airflow throughout the building. Most often, rebalancing the dampers will solve the problem.

Malfunctioning Thermostat

Sometimes, the problem isn’t with the HVAC system or rooftop chiller; it’s with the thermostat, responsible for the amount of air produced and regulating system timing. A malfunctioning thermostat can cause temperature fluctuations, which could cause discomfort within the building.
