Endeavouring to fix air conditioning units throughout your building before summer sets in is the best way to achieve and maintain a comfortable working environment for your employees. Air conditioning maintenance is an integral component of keeping your air conditioning running optimally and identifying potential issues before they become emergencies. 

In this article, we discuss the three most commonly problematic components of an air conditioner and detail how to fix air conditioning units so you have adequate air conditioning in summer this year.


The filters inside your air conditioner are responsible for trapping dust, pollen, and other small particles present in the air to create a higher-quality air output in your rooms. A clogged air filter is the most common reason you may need to fix air conditioning units in your building. But the solution to this problem is quite simple. 

Changing or cleaning your air filters, depending on the type, should be the first step of air conditioning maintenance. This is because a clogged air filter can reduce the efficiency of your air conditioner so much that you may believe it is broken when it actually isn’t. 

We recommend you change or clean your air filters every 30 to 45 days to achieve maximum efficiency and maintain the air quality in your building. Changing non-reusable air filters more frequently than this can lead to unnecessary waste, but leaving your filters for extended periods can encourage your air conditioner to work harder than it needs to, and lessen the air quality substantially. 

Top up the Refrigerant

The refrigerant is the fluid inside your air conditioner which absorbs heat throughout the process of transforming low-pressure gases into high-pressure liquids. This process produces the cool air your air conditioner expels. 

Again, a lack of cool air from your air conditioner may lead you to believe that you need to fix air conditioning units in your building, but the solution is simple. 

If your refrigerant needs a top-up, we recommend contacting an experienced specialist to conduct air conditioning maintenance and bring your refrigerant levels back up.

Check the coils

To prepare for use of your air conditioning in summer, we recommend you check the internal coils for dirt and deterioration. The coil is responsible for cooling the refrigerant to better absorb warmer external temperatures. But if the coil is dirty or damaged, you may notice warm air coming from your air conditioning or even leaking. 

Air conditioner coils should last upwards of 15 years of use, but in the case that they become damaged, a replacement is the only option. 

If your air conditioner is experiencing either of these issues, you should again contact a professional to fix air conditioning units in your building. Water and electricity are a dangerous mix. But fortunately, a specialist can quickly and efficiently replace the coils, so we recommend shutting off the system and getting in touch as soon as possible.
