4 Common HVAC Problems in Commercial Buildings


Are you experiencing HVAC problems in your commercial building?

HVAC issues in buildings that house sensitive and valuable equipment are a common occurrence. This problem often stems from the faulty equipment itself.

This is due to the range of different types of heat and products that run through them. You need to be able to detect these issues as and when they occur.

But what are the most common HVAC problems that affect commercial buildings?

Here, we’re going to give you a guide on a handful of the more frequent ones so that you can prevent them from occurring.

1. Poor Indoor Air Quality

Common HVAC issues that can affect indoor air quality are a lack of ventilation, unclean air filters, and polluted air ducts. When not enough fresh air is brought into a building, contaminants can build up and cause poor air quality. Additionally, poorly-sealed windows and doors can also be a source of heat loss.

Once you can identify the issue and its cause. It is easy to direct your troubleshooting towards fixing the problem most easily and efficiently. In extreme cases, poorly insulated buildings can even experience condensation and moisture problems.

2. Frozen Coils

When the air conditioner is not operating properly and the condenser coils get too cold the refrigerant inside them can start to freeze. This can damage the coils and reduce the efficiency of the system. Another issue is when the building’s ductwork is not properly insulated, dirty air filters, and the coils are not cleaned regularly.

This can cause the refrigerant to lose heat as it travels through the ducts, causing the coils to freeze. Finally, if the air conditioner is not sized for the building, it can struggle to work, causing the coils to freeze.

3. Leaks in the Ductwork

Loose connections, holes or cracks in the ductwork, or incorrect installation, can cause condensation. That can lead to moisture problems and mold growth. Over time, this ductwork can become damaged or disconnected.

These problems include lack of airflow, uneven temperatures, and poor indoor air quality. If you notice any of these problems, have a qualified HVAC contractor. They will take a look at your system to determine the cause and make your HVAC repairs.

You can also check with commercial HVAC services if you are not sure about how the ductwork works.

4. Excessive Noise

Noise levels in HVAC systems are caused by imbalanced fans, failing bearings, and loose components. Imbalanced fans can be caused by many factors, including incorrect airfoil installation, damaged blades, or bent blades.

Failing bearings can result from improper lubrication, lack of maintenance, or debris build-up. Loose components can create rattling or vibrating noises and are the result of poorly designed or installed systems.

Identify Your HVAC Problems

If your heating or cooling system isn’t working properly, it could be due to a variety of issues. Once you have a better idea of what might be causing the issue, you can start to troubleshoot the problem. If you’re not sure how to fix it, though, it’s always best to call in a professional.

Maintaining your HVAC system can help avoid these common HVAC problems. It will keep your building running smoothly.
