How the heat has affected your air conditioner over summer

Did you know that air conditioning systems are designed to function with outside temperatures of 35 degrees or less? Therefore, when temperatures outside become higher than 35 degrees for sustained periods of time, the air conditioning system can consume more energy and is at an increased risk of malfunctioning or failing. This also means that your air conditioner has been working at max capacity for a long period of time.

When an air conditioning system is operating at its peak operating ability for a prolonged period, it can have several effects on the system’s performance and longevity. Some of the ways high outdoor temperatures can affect your air conditioner over the summer include:

Increased energy consumption

When the temperature outside exceeds 35 degrees Celsius, your air conditioner will have to work so much harder to cool your home, which can cause it to consume more energy. This increased energy consumption can lead to higher energy bills and put extra strain on the system, which can lead to breakdowns or malfunctions.

Reduced aircon efficiency

As an air conditioning system operates at its maximum capacity, it may struggle to maintain the desired indoor temperature. This reduced efficiency can cause the system to run longer and work harder. Which can lead to increased wear and tear, reduced performance, and a shorter lifespan.


In extreme cases, when an air conditioner runs continuously at maximum capacity in high temperatures it can overheat. This can cause the system to shut down, malfunction, or fail altogether.

Dirty filters & fans

When an air conditioner runs consistently in hot weather the air filters can become clogged with dirt and debris, reducing the system’s efficiency and potentially damaging the unit. The outdoor unit fan can also accumulate dust much faster than normal, increasing the energy needed for the system to work.

Air conditioner cleaning

What can you do?

Therefore, regularly cleaning the aircon filters and outdoor unit grill and fan is a great way to keep the unit working effectively and efficiently.

To minimize the effects of high temperatures on your aircon, it’s essential to ensure that your system is well-maintained and regularly serviced by a professional. This can help identify any potential issues and ensure that your aircon is running as efficiently as possible. It’s also important to limit the use of your aircon during the hottest parts of the day and use other cooling methods, such as fans or shades, to reduce the load on your air conditioning system.
