Business establishments and other major facilities can only remain comfortable to work in and convenient to visit if they have commercial HVAC systems to make them so. So, what is commercial HVAC? It’s simply that giant machine that warms, ventilates, or keeps the air cool on company grounds. They may, however, develop problems that impair performance. Listed here are common HVAC issues and their solutions.

1. Poor Airflow

Clogged air filters, blocked vents, broken blower motors, or obstacles in the ductwork can all cause weak or irregular airflow. Improper ventilation raises wear of parts and energy consumption.

• The Fix: Replace or clean air filters regularly. Clean them on a monthly basis and replace them at least every three months. Inspect your ductwork for leaks or blockages. Seal the leaks and clear away any obstructions. Lastly, check the blower motor and fan for damage, lubricate the bearings, and give their wiring a closer look.
  
  

2. Refrigerant Leaks

The HVAC system may have trouble cooling due to a low refrigerant level brought on by a leak. This could result in compressor failure and increased energy costs. Ice accumulation on coils is a sign of a refrigerant leak.

• The Fix: An HVAC technician can locate and repair the source with the use of a refrigerant detector. The pro can then seal it and recharge your system. It’s important to remember that simply adding more refrigerant and not fixing the leak is a short-term solution. This may pose risks for people in the workplace.
  
  

3. Thermostat Malfunctions

A malfunctioning thermostat can result in brief cycling, incorrect temperature readings, or eventually a system failure. Defective wiring and dead batteries, or inaccurate calibration, result in energy waste and discomfort.

• The Fix: Make sure the thermostat is functioning properly by checking the power and wiring. Replace the batteries if needed and verify that all connections are secure. Consider upgrading from an old thermostat to a smart model. You can even set schedules for the heating or cooling of the site with the new version.
  
  

4. Frozen Evaporator Coils

When evaporator coils freeze, it can result in inadequate cooling and possible water damage from the melting ice. Let’s deal with how to fix an HVAC system when dirty coils or restricted airflow arise to plague the apparatus.

• The Fix: Start by turning the system off and allowing the coils to melt. Use a fan to help speed up the thawing process. Once that’s done, clean them with a soft brush or coil cleaner, as dirt and debris cause freezing. Also, check the refrigerant level if it’s low because this could mean a leak and cause the HVAC’s restricted airflow.
  
  

5. Unusual Noises

Odd sounds like banging, rattling, or screeching emanating from the HVAC are a problem. They might be due to worn belts, malfunctioning motors, and loose parts. Ignoring them can lead to system failure or costly repairs.

• The Fix: First, tighten any loose parts, as vibrations loosen screws, bolts, and even fan blades over time. Tightening all accessible components can make a big difference. Next, lubricate bearings and motors to prevent friction-related noises. Lastly, replace worn-out belts or bent fan blades that lead to squealing.
  
  

Summing It Up

To prevent serious malfunctions, commercial HVAC systems need to be inspected and maintained regularly. If a company is to achieve all that commercial HVAC is for, businesses must address the system’s common problems. Always seek the professional assistance of a certified HVAC specialist.
