Discover the signs your air conditioning system needs to be serviced or replaced here.
Replacing or servicing your workplace air conditioning unit can often be something you don’t regularly think of, until it’s too late; resulting in unplanned expense, and very warm and uncomfortable members of staff and visitors.
The latest generation of air conditioning units change between heating and cooling seamlessly, so any questions over whether it is working has the potential that there is a problem.
Here at IRS, we have put together some warning signs that your AC will start to show, when it’s time to think about replacing or servicing your air conditioner.
Anything which makes a strange sound that doesn’t normally – is likely not meant to be. These sounds can include anything out of the usual such as rattling, gurgling, squeaking, grinding… the list goes on. Unusual noises are not simply a sign of old age and should be considered as a potential hazard. Majority of AC units have a common white-noise whilst they are working away at keeping you cool, which we can barely hear; therefore, if your piece of cooling kit is putting on a noisy show – it’s a big sign it’s time to be services or replaced! These factors can also increase your energy bill costs significantly, as the unit is using more electricity to stay working.
Excess moisture in places where it shouldn’t be is never a good sign for any piece of equipment – especially air conditioning units. All AC units produce some levels of moisture as they work, and if they are functioning properly, they will be able to handle this without an issue. However, if there is leakage coming from your unit, it is likely that you are dealing with a blocked drain, failed condense pump, or the evaporator could be frozen due to low pressure (refrigerant leak) which will cause your system to under-perform.
Signs of a Refrigerant Leak
Do you have the signs of a refrigerant leak?
- Loss of cooling power
Refrigerant plays an extremely important role in the cooling process. It’s the refrigerants job to absorb the heat from your workplace and release it outside. If your refrigerant levels are depleted, it will take longer to cool your home or business, which often results in a visit to the thermostat for a downward temperature adjustment.
- Registers not blowing cool air
One part of your quick analysis for an AC refrigerant leak is to check the air coming from your registers (vents). If the air is not as cold as it should be, it could mean a HVAC refrigerant leak.
- Hissing sounds coming from your indoor unit
An air conditioning refrigerant leak is caused by holes or cracks in the coils that circulate the refrigerant. Though hissing could be a sign of a variety of problems, refrigerant leaks are among them. A larger leak may produce a gurgling sound.
- Coils are frozen
When the refrigerant levels circulating through the evaporator coils is insufficient, the coils will not adequately absorb heat. This will result in the condensation on the coils to freeze. Sometimes the frozen condensation will begin to melt and drip on the floor. Though ice on the evaporator coil might not seem alarming, it could lead to a system breakdown and could translate into an expensive repair such as a compressor replacement.
An air conditioning refrigerant leak means elevated electric bills! If the leak is negatively impacting your comfort level and causing you to dial down the thermostat in the hope of getting cooler air, you will be using more electricity. Review your utility bill for inconsistent usage levels – especially when compared to the timeframe last year.
Lack of Cool Air and Air Flow
One of the most obvious signs that your air conditioning system needs to be replaced is due to the lack of cool air and air flow coming from it. If your air conditioning unit does not produce cool air within a couple of minutes of being switched on, it is likely it is not performing as it should be and needs to be checked or replaced.
High Energy Bills
Have you noticed that your energy bills have been sky-high recently? A 5KW A/C system (an office with 6-8 staff) typically costs £2.20 per day to run if working constantly. A well-sized unit should run, on average, at approximately 60% of this figure. This equates to £320 per year for a system running at design, opposed to £530 for a system that is poorly performing.
No one likes a high energy bill, and no one likes to be hot and bothered whilst reading it!
