As effective as a commercial central heating, ventilating and air conditioning (HVAC) system is at keeping employees comfortable and productive, it is still a machine that needs to be maintained like all machines do. Summertime in Las Vegas, NV, is no place to be without a well-maintained system. We’ve listed several common commercial HVAC issues that you’ll want to keep an eye out for.

Poor Air Quality

Airborne contaminants negatively affect your health and the health of your employees. This is especially true of contaminants known as volatile organic compounds (VOCs). VOCs are emitted into the air in gas form from building materials and furnishings, office equipment, glues and adhesives, and so on.

At the very minimum, you need to change the filters in your HVAC monthly as part of your HVAC’s regular upkeep. An in-line air purifier would greatly improve air quality.

Leaking Refrigerant

Refrigerants are the liquid agents that cool the air that an HVAC pushes out. You’ll want to make sure that your unit does not leak refrigerant. If an air conditioner runs without sufficient refrigerant in it, the HVAC will not put out cool air, but it will keep trying to match the thermostat setting, overworking the condenser and increasing the utility bill.

Commercial HVAC Thermostat Issues

Sometimes it’s the thermostat rather than the HVAC system that causes problems. Thermostats tell the HVAC system how much hot or cold air to produce and when to shut the HVAC off or on.

If your business has more than one thermostat and you notice that one part of the building is always too warm in the summertime, you may have a faulty thermostat. Or perhaps you have a thermostat that needs to be installed in a better location. Of course, it is always possible that you’ve got an employee who adjusts the thermostat to make himself comfortable at the expense of everyone else.

If a thermostat issue is not the reason for dramatically different temperatures in a building, an inconsistent airflow may be the problem. This is likely caused by an unbalanced system or by leaks or cracks in the ductwork. Call one of our professionals to fix any problems regarding varying temperatures.

Incorrect Commercial HVAC System Size

Your business’s HVAC system should be the right size for the amount of space it cools. Otherwise, your unit would not be able to properly do its job. One of our knowledgeable technicians will be able to determine whether your unit is the right size for your business.

Pump Shaft Damage

An overloaded or imbalanced HVAC system can overheat, damaging the pump shaft and causing the air conditioner to stop working. An HVAC contractor can look for signs of overheating, causes of imbalance, and so on.

Leaking Seals

Commercial HVAC systems have mechanical seals that act as a barrier between a moving and a stationary part. They protect against wear and tear and also leaks. Pump seals must stay adequately lubricated so that they can prevent seal faces from expanding, cracking and leaking in the event that the pump or compressor overheats.

Commercial HVAC Fan Damage

If your HVAC system is installed on the roof, the fan is protected from hail and other threats by a housing component. Still, wind and storms can carry enough dirt and debris into the fan to damage it. Fans need regular maintenance.

If you hear strange noises coming from your HVAC, you definitely need to call a professional. The problem could be a broken fan, disconnected ductwork, or some other problem that you’ll need to have an expert investigate.

A commercial HVAC system is a complex one that requires timely maintenance by an HVAC specialist. Procrastination can lead to bigger problems. Whether your unit needs immediate attention or just a checkup, contact Zen Aire Air Conditioning and Heating of Las Vegas, NV.
