Top 5 Commercial HVAC System Issues

Top 5 Commercial HVAC System Issues

While it is true that your commercial HVAC system is sturdy, it doesn’t exclude you from unexpected issues. You can prevent unwanted situations by knowing these top 5 commercial heating and cooling problems.

#1 Low Refrigerant Charge

Refrigerant is a chemical liquid needed by your HVAC system to perform its cooling job. Leaks are the main culprit of a low refrigerant charge. Some of the key signs that your A/C is low on refrigerant are the following:

  • Ice build-up on your coils or condenser
  • Longer time to cool your home
  • A sudden spike in your electric bills
  • Unusual and loud noises like hissing or bubbling

As a result, your cooling system is forced to work harder, leading to early breakdown and unnecessary repair costs. Call the experts to refill your air conditioner’s refrigerant. 

#2 Faulty Thermostats

Do you feel too cold in one part of your home and feel warm in the other areas? If that’s the case, it could be caused by a faulty thermostat. Others reasons include a bad location, frayed wires, and dirty thermostats. If you’re still using the old, manual-type thermostat you may consider switching to a programmable type. It is more accurate, convenient, and energy-efficient.

#3 Clogged Drain Line

A clogged drain line is another commercial HVAC system issue which is caused by algae, mold, or mildew that may build up in your pipe.  Consequently, it may cause water leaks and damage your unit. To clean or unclog your drain line, you may use vinegar, baking soda, or shop vac. Here are the step-by-step procedures:

  • First, turn off your A/C unit. Check the breaker or fuse box to shut it down completely.
  • Locate your drain line’s access or exit point.
  • Next, attach the shop vac hose to the drain line or pour a cup of vinegar to the access point and let it sit for a few hours.
  • Lastly, if it’s still clogged, you may try the exit point of your drain line or leave the cleaning to the repairman.

#4 Airflow Issues

Poor indoor humidity and inconsistent temperature are caused by air leaks from your ductwork system. You need to get your air ducts cleaned regularly and serviced by licensed technicians. They can locate the source of the problem, provide a quick fix, and ensure the repair is done correctly and professionally.

#5 Pump Shaft Issue

Leaks, rattling noises, and reduced fluid flow are some of the obvious signs of pump shaft issue. Excessive heat can cause your heating and cooling unit to overload or imbalance. When this happens, your commercial HVAC system tends to breakdown completely. In this case, you need to call a certified technician to diagnose the problem and repair it right away. There are instances where replacement is your best option, especially when your pump shaft is damaged.
