5 Signs You Need Commercial Air Conditioning Servicing


There is nothing worse than ignoring air conditioning warning signs before summer comes around. As temperatures rise, your commercial air conditioner could decrease in efficiency or stop working altogether. Take action now to avoid breaking a sweat when summer arrives.

The global commercial air conditioning market is projected to reach over 19 million units by 2026. While air conditioners continue to become more efficient, regular commercial air conditioning servicing is essential to keep systems in the best condition.

Are you unsure if you need an air conditioning service? Read on for five signs that it is time to arrange a commercial air conditioning service.

1. Unusual Noises

It is usual for your commercial air conditioning to make some noises while running. However, if you begin to notice new or unusual sounds, it could be time for air conditioning servicing. Unusual sounds can include:

  • Whistling
  • Grinding
  • Buzzing
  • Rattling
  • Shrieking
  • Screeching

There are many reasons why your air conditioning unit could be making unusual noises. Screeching noises usually indicate there is a broken motor or fan motor. Buzzing sounds can indicate loose parts, dirty condenser coils, or refrigerant leaks.

Rattling could be just because of loose debris, but a damaged electrical system could also cause it. Grinding noises are often caused by the compressor, when it has worn down, or a loose fan belt. It usually indicates you need a new compressor or a new fan belt.

It is best to call a professional air conditioning repair service to inspect unusual noises because commercial air conditioning units need to be handled with care. Handling your commercial unit without experience poses many risks, such as refrigerant exposure.

2. Blowing Warm Air

A common sign you need commercial air conditioning servicing is warm air. If you notice warm air is coming out of your air conditioner vents and it is in cooling mode, take action fast. You want to maintain optimum temperatures in your commercial property, and an air conditioner blowing warm air can quickly escalate.

A common reason for an air conditioner blowing warm air is that the filters need to be cleaned or replaced. Your commercial air conditioner model depends on how often you need to replace filters. However, there are other causes too, including a damaged compressor, dirty compressor coils, or a leak.

An HVAC air conditioning service will ensure your unit is blowing cool air again in no time.

3. Thermostat Issues

Your air conditioner’s thermostat can cause many problems with your air conditioning. Common signs of thermostat issues include:

  • The air conditioner stops working
  • Short cycling or always running
  • The unit will not turn on
  • Unit not heating or cooling efficiently
  • The unit will not turn off

Thermostat issues happen for various reasons, including internal malfunctioning or poor installation. Other common causes of thermostat issues are where it is positioned in your home or that it needs replacing. It could also be a simple fix, such as needing new batteries!

It is best to get a professional air conditioner service to look at the issue, as it can do more harm than good to attempt to fix the thermostat or any other air conditioner issues. There are various thermostats, so get a professional to examine the problem before your thermostat entirely breaks.

4. Leaks

While it is natural for your commercial air conditioner to experience some condensation during the cooling and dehumidification process, excess moisture indicates an issue. Common signs of air conditioner water leaks include water dripping or pooling around your unit. You may also notice water marks or long cooling cycles with poor performance.

Water leaks suggest there is something preventing water from draining efficiently. There could be a blockage in the drainpipe or the filters, which restricts airflow to the evaporator coil. When the evaporator coil does not get sufficient airflow, its coils can freeze.

Refrigerant leaks can also occur in your air conditioning unit. If you notice hissing sounds, frozen coils, or a loss of cooling power, it is time to call an air conditioning repair service.

5. Rising Bills

Investing in a commercial air conditioning unit should bring you great returns. However, if you neglect air conditioning servicing, costs quickly outweigh the benefits. One of the first signs you have an issue with your air conditioning unit is if you are noticing rising utility bills each month.

An air conditioning unit requires more electricity than a standard fan, but your air conditioner unit could be to blame if your utility bills are steadily rising without another cause. An inefficient air conditioner will quickly increase electricity costs, as it will need more power to attempt to cool your space.

First, check you do not have any other issues with your electricity or wiring. Also, consider if there are other reasons why your utility bills are higher. However, even if you do not find other signs that you need an air conditioner service, it is best to schedule a service to inspect your unit. There are many reasons why your air conditioner unit could be using more energy than it should.

And the longer you avoid scheduling an air conditioner service; the more costly your energy bills will become. The HVAC technician will be able to troubleshoot what is wrong with your unit. Sometimes, if a unit is old, replacing the unit with a new energy-efficient option may be more effective.

Commercial Air Conditioning Servicing

Do not delay commercial air conditioning servicing. It is best to address any air conditioner issues before the summer months so your unit is ready to keep your commercial space comfortable as temperatures rise. The longer you ignore warning signs, the more severe the problem can be. Even if your air conditioner appears to be working well, arrange a routine maintenance plan. A professional service will deal with problems before they escalate and ensure your unit stays efficient year-round.
