Quick guide on air con checkup before summer

Quick Guide on Air Con Checkup Before Summer


A good air con checkup before summer is your key to ensuring its correct running and efficient operation during the season.
​

Here is a quick guide on air con checkup before summer with a list of tasks you can do yourself and an overview of what to expect from a professional tune-up.

DIY checkup list

Here are the tasks you can handle without any special tools or technical knowledge:
  • Run a test cycle
  • Clear debris around the outdoor unit
  • Clean or replace air filters
  • Check vent openings

​To clarify, running a test cycle enables you to check that the system operates properly, providing cold air as it should, and to ensure the cycles are not erratic. If you detect an issue that you cannot resolve with cleaning, turn to qualified engineers for a professional air conditioner repair.
For proper airflow, the outdoor condenser needs at least 2 feet of clear space around it – no leaves, branches, grass, or any plants. For the top performance, you need a clean air filter as a clogged filter restricts airflow and makes your AC work harder. Also, for normal running, the system needs open vents, because closed or blocked vent openings can increase pressure in the ductwork and cause leaks.

Professional checkup list

A professional checkup goes deeper, focusing on internal components that require specialised knowledge, training, and tools:
  • Inspecting electrical components
  • Lubricating moving parts
  • Checking refrigerant levels and refilling, if necessary
  • Checking the ductwork for leaks
  • Deep coil cleaning

​When turning to professional HVAC engineers, you can expect them to check the capacitor and inspect and tighten electrical connections to ensure efficient running and prevent risks of electrocution.
Besides, while you can clean the unit outside, a technician can access and chemically clean the indoor evaporator coils and drain line, which are a magnet for dust and can lose efficiency if grimy.
​

To sum up, the DIY tasks listed above are the minimum that you should undertake to prepare your air con for the summer season. However, it is worth engaging professional F-Gas certified engineers to prepare an air con in the best possible way.
