Residential Air Conditioning

Regular servicing is essential to ensure the optimal performance and longevity of air conditioning for residential properties. The frequency of servicing can vary depending on several factors, including the type of air conditioner, usage patterns, and environmental conditions. Here are some general guidelines:

• Annual / Seasonal Servicing: It is recommended to have your home air conditioner serviced at least once a year, depending on use. This routine maintenance helps identify and address any minor issues before they escalate into major problems. As Australia is exposed to a wide range of extreme temperatures, it is recommended to schedule frequent servicing of your air conditioning in Australia. This ensures that your unit is in top shape and ready to perform at its best.

• Filter Maintenance: Clogged or dirty filters can hinder airflow and reduce efficiency. It’s recommended that you clean the indoor units every 1 to 3  months, although this varies by model. Refer to the manufacturer’s operating manual on the recommended frequency and how to access and remove the filter from the indoor unit. 

• Environmental Considerations: It’s important to make sure to keep the outdoor unit free from debris and obstructions. Like with indoor units, debris can build-up on the outdoor unit fins, restricting airflow. This can cause the compressor to work harder, leading to higher energy usage and increased running costs.. If you live in an area with high pollution, dust, or allergens, it may be necessary to service your air conditioner more frequently.

Determining the appropriate size of a domestic air conditioning system requires careful consideration of several factors. Here are some guidelines to help you estimate the size:

• Calculate the square metre: Measure the square metres of the area you want to heat/cool. Multiply the length and width of each room, and then add up the metre footage of all the rooms you plan to heat/cool. This will give you a rough estimate of the total area to be heated/cooled by your home air conditioner.

• Consider insulation and ceiling height: Take into account the quality of insulation in your home and the height of your ceilings. Well-insulated homes retain cool and warm air more effectively, reducing the workload of the air conditioning system.  Homes with poor insulation may require a more powerful air conditioning system.  Higher ceilings may require more heating/cooling power. All of these factors may affect your unit selection.

• Request a heat load assessment: A heat load assessment is an important component of the quote process conducted by an air conditioning specialist. This is to ensure the correct size and type of air conditioning system is specified and installed, providing you with the most efficient solution. New residential air conditioning standards ensure specialists are adhering to these requests. 

• Consult a HVAC professional: For the most precise sizing recommendation, it's advisable to consult with a licensed HVAC professional. They can perform a thorough evaluation of your home's heating/cooling needs, considering factors like insulation, airflow, power supply, ductwork, and specific environmental conditions.

Over time, the filter inside residential air conditioners will fill up with dirt and debris, which can impact the performance and efficiency of the unit. To combat this process, it is recommended that you clean the filter at least every one to three months. Filters that are cracked or damaged in any other way should be replaced with a new one. For more information, please see our blog outlining how to clean an air conditioner.

When you are selecting your home air conditioning setup, there are a number of viable options to choose from. If you need to cool more than one room, you will most likely be choosing between a multi split system air conditioner and a ducted system. While it may seem like these systems achieve the same thing, there are a number of important differences that differentiate them.

A multi split system air conditioner consists of an externally mounted compressor and a number of individual indoor units. The individual units heat or cool one room independently of one another, each with their own remote control.

In contrast, ducted air conditioners feature a singular unit that is connected to vents in the ceiling of each room through a series of ductwork. Ducted systems can be zoned to offer occupants control over the temperature in each room. Another benefit of a ducted home air conditioner is that the vents integrate into the ceiling, creating a cleaner aesthetic in the room.

When selecting your next home air conditioning setup, it’s important to consider what matters to you and your family. Not only will this guide you towards the right type of home air conditioner, it will also help you choose a system that provides all the functionality your household requires. When choosing air conditioning for residential use, we recommend you consider:

• Energy efficiency: Research the energy efficiency ratings and technical specifications of each unit you are considering.

• Size: Have your home measured by a professional to determine the most suitable air conditioner for optimal performance and efficiency.

• Noise: Research the amount of noise produced by each home air conditioner to ensure the unit will not impact members of your household when they are sleeping.

• Home design constraints: The design and layout of your home may preclude you from installing certain types of air conditioners. For example, If your home is an older design, or has tall ceilings, you may not be able to fit a ducted air conditioner in your home.

• Features: Programmable thermostats, efficient operating modes, sleep timers and motion detectors are all handy features to have in your home air conditioning system, for improved performance and efficiency.
