Air Conditioning Service Guide

Air conditioning is essential in modern living, but while enjoying the comfort of cool air, we also need to be mindful of maintenance and repairs. This guide explains common air conditioning service issues, including installation, cleaning, and refrigerant refilling. It helps you understand your needs better, making it easier to communicate with technicians.

Identifying the Type of Air Conditioner

Air conditioners generally fall into two categories: window units and split systems. Identifying the type is crucial as the repair methods, required materials, and costs vary significantly between them. This guide will focus on these two common types. If you're unsure which one you have, take a photo and consult with an aircon technician. For larger units, like central air systems or those used in stores and restaurants, you will need to directly consult with a technician.

Air Conditioner Installation

Once you've determined the type of air conditioner, measure the installation area to ensure there's enough space. You may need to install additional brackets or scaffolding on the exterior walls. Be sure to clearly communicate your AC installation environment and requirements to the technician for an accurate quote, and to ensure they bring the necessary tools and materials. Additional charges may apply for tasks like sealing edges with glass or film, upgrading electrical wiring, drilling walls for split system pipes, connecting extra-long refrigerant pipes, or carrying equipment upstairs without an elevator.

Air Conditioner Cleaning

If you're using a window air conditioner, discuss with the technician whether the unit needs to be taken back to their workshop for cleaning, as this could incur extra fees. You’ll also need to decide if a parts inspection or replacement is necessary. For split systems, the technician typically only cleans the indoor unit, so if you require outdoor compressor cleaning, be sure to inform them. When connecting with the technician, please communicate your AC cleaning environment and specific requirements clearly to receive an accurate quote.

Adding Refrigerant

Before adding refrigerant to your air conditioner, it's important to identify the cause of the leak. Under normal circumstances, refrigerant is sealed within the pipes and should not deplete. If the refrigerant is leaking, it could be due to damage to the pipes during improper handling, or loose fittings from a poor installation job. Before refilling, fix the root cause of the leak. Otherwise, adding refrigerant will be pointless and could harm the environment.

It’s important to note that each air conditioner has a specific refrigerant pressure requirement, so you can't just add as much as you like. Always hire an technician to handle refrigerant top up.
