Whether it is poor airflow or problem with your smart thermostats, there could be several reasons that can cause your air conditioning systems to not function properly. 

So, let us check out some of these common issues and understand how to solve them for maximum comfort.

1. Insufficient cooling and heating

Reasons:

• Clogged air filters 

Clogged filters are the most common reason that leads to insufficient cooling. You must regularly check and replace filters as per the recommended schedule. Also, always take help from professional HVAC service companies for commercial buildings to avoid any mistake and ensure proper replacement of filter.

• Low refrigerant levels

Normally, leaks and regular usage of air conditioning systems lead to depletion of refrigerant levels. And if you are experiencing lower cooling, then it may be a sign that your refrigerant level is reducing. So, contact professionals to check for a refrigerant leak detection and top-up if necessary.

• Faulty thermostat

Often thermostats are improperly configured that can send incorrect signals to the AC unit. It leads to improper temperature regulation, and therefore regularly check for thermostat settings and ensure they are functioning correctly.

• Blocked vents

In commercial buildings there are several stuffs such as furnitures, boxes, or other kinds of obstructions near vents that may hinder airflow and prevent proper colling in specific areas. So, check there are no obstructions and they are clear.

• Improper system sizing

If you opt for AC unit with smaller size than as required for your commercial space, then its definitely not going to help you cool properly. Consult professional HVAC service companies like Everest Mechanical to find out the best AC configuration for your building.

2. Uneven Temperatures Throughout the building

Reasons:

• Blocked vents and registers

As discussed earlier, blocked vents can disrupt airflow and cause temperature inconsistencies in different areas.

• Duct Leaks

If there are leaks in the ductwork, then the conditioned air can escape before reaching the designated area. This is another cause of uneven cooling. Consult professionals to inspect thoroughly and identify areas that must be sealed.

• Improper zoning controls

Commercial buildings have multiple zones that might have malfunctioning zoning controls. And therefore, you might be experiencing uneven cooling at various areas of your commercial building. So, ensure that zoning systems are working properly as intended.

3. Reduced Indoor Air Quality

Reasons:

• Dirty air filters

Clogged filters are the main reason for reduced air flow. They trap dusts, allergens, and other contaminants, that may impact the indoor air quality.

• Clogged condensate drain lines

If there are clogged drain line, then they can prevent the AC from properly disposing of condensate (moisture), which can lead to mold growth and poor air quality.

• Lack of ventilation

If your building has inadequate ventilation, then it can trap stale air and pollutants that also leads to poor air quality. In such cases, schedule regular maintenance to check and clean condensate drain lines, as well as ensure proper ventilation throughout the building.

4. Unusual Noises

Reasons:

• Worn out bearings

Over time, bearings in the AC unit can wear out that may cause grinding or squeaking noises. This issue requires professional repair or replacement of the worn out components.

• Loose components

If there are loose screws, bolts, and other parts within the AC unit, then it can vibrate and create rattling noises. Contact qualified technicians to find out such components and fix them before it becomes major issue.

• Refrigerant Leaks

This leads to hissing or bubbling sound. It is a serious issue that can lead to safety and hazardous issues. Therefore, it requires professional address.

5. Unresponsive Systems

Reasons:

• Power outages

Power outage may lead to unresponsive AC system as the entire unit relies on electricity to function. If there are power cuts, then it will obviously prevent it from turning on, and running on inverter may lead to abnormal functioning.

• Tripped circuit breakers

AC units are usually connected to dedicated circuit breakers in the building’s electrical panel. If these breakers trip for any reason, then the AC unit will lose power and stop functioning.

• Faulty controls

The AC unit’s controls, including the thermostat and internal control boards, can malfunction and prevent the system from responding to commands. This could be due to electrical issues, damaged components, or communication problems within the system. 

Do you need to call professionals for these issues?

Well, the most of the issues are common, and can be addressed without needing professionals, and can be done with inhouse staffs. However, it is important to know when you should call professionals for help. Here are some situations that must be addressed by professional HVAC service companies:

• Complex issues: If troubleshooting steps fail to resolve the problem, or if the issue seems complex (e.g., refrigerant leaks, electrical problems), it’s best to call a professional for proper diagnosis and repair.
• Strange noises: Unusual noises like grinding, screeching, or loud vibrations can indicate serious problems. Don’t ignore these and call a technician for immediate inspection.
• Safety concerns: A suspected refrigerant leak poses a safety hazard. Refrigerant is a harmful substance, and leaks require professional attention to avoid health risks.
• Frequent breakdowns: Frequent breakdowns are a sign of underlying issues within the AC system. A professional can diagnose the root cause and prevent further problems

Professionals don’t just fix these issues in AC unit in your commercial building but with their expertise and tools, they can diagnose the problem more accurately, find the right parts to repair, and prevent any accidental consequences. Thus they help to minimize downtime and disruptions.
