What Are the Benefits of Regular Air Conditioning Maintenance?
Think of your air conditioning system like your car. You wouldn’t drive 100,000 km without an oil change, right? Your air conditioning unit works hard every summer (and sometimes in winter for heating). Dust, pollen, and pet hair clog your air filter and evaporator coil, making the system strain to deliver cool air over time without maintenance.
A clogged air filter alone can cut your system’s efficiency by up to 15%, according to the U.S. Department of Energy. Dirty condenser coils force the compressor to run longer, increasing energy costs and shortening its lifespan. Even worse, ignoring maintenance can lead to refrigerant leaks, resulting in costly repairs or the need for air conditioning repairs in Adelaide.
Extending the lifespan of your air conditioner
With regular maintenance, your air conditioner can enjoy a longer lifespan. This is because regular maintenance helps to identify and fix minor problems before they have a chance to snowball into expensive issues, such as compressor failure, refrigerant leaks, and complete system breakdowns.
Improving energy efficiency
Unfortunately, if your air conditioner is not properly maintained, it will not only be unable to provide optimal comfort but will also consume more energy. An air conditioner that isn’t functioning at its best is a sure way to blow up your utility bills and leave you feeling frustrated. A well-maintained air conditioner will run more efficiently, meaning it won’t have to work as hard (and use as much energy) to cool your home, leading to significant savings on your utility bills over time. It’s ultimately a small price to pay to avoid significant problems down the road.
Improving comfort
When your air conditioner is running at its best, you’ll be able to enjoy optimal comfort in your home. Forget about hot spots, uneven cooling, dry air, or feeling stuffy; regular maintenance allows you to enjoy a comfortable climate all year round.
Healthier Air
One of the benefits of an optimised air conditioner is that it will help to purify the air in your home. By keeping your system in good shape, you can help ensure that the air in your home is free from dust, airborne pollutants, and mould.
What Does a Full Air Conditioning Maintenance Service Include?
A full air conditioning maintenance covers everything: cleaning or replacing filters, inspecting refrigerant levels, clearing the external unit, and ensuring your system runs at maximum efficiency. Here’s what a standard air conditioner service looks like:
- Inspecting and cleaning the air filter: A dirty filter is one of the main causes of inefficient operation and poor performance. We clean or replace it to keep your air conditioner needs covered.
- Checking the evaporator and condenser coils: Over time, coils collect dirt, reducing heat absorption and increasing running costs. A thorough clean boosts system efficiency and ensures better cool air flow.
- Measuring refrigerant levels: Low or imbalanced gas levels can destroy compressor performance and send energy bills soaring. Our techs top them up to manufacturer standards.
- Testing the thermostat and controls: Your climate comfort depends on accurate controls. We check that your climate control system responds precisely, so you never get stuck sweating.
- Inspecting electrical components: Faulty electrical connections are a major reason why an air conditioner breaks down unexpectedly. We tighten connections and look for worn parts.
- Cleaning the external unit and drain lines: Blocked drain lines cause leaks and water damage. We flush them and ensure your external unit breathes freely.
- Assessing the ductwork: For ducted air conditioning maintenance, we check for leaks or insulation damage that can compromise cooling system efficiency.
All this ensures your air conditioning unit keeps you comfortable without eating up your budget.
How can I keep my AC unit in good condition?
Maintaining the health of your AC unit isn’t limited to professional tune-ups; there are also a few things that you can do to contribute to the longevity of your system.
Wall Mounted units or split systems
Wall mounted, or split system air conditioners, are the most common type of air conditioner found in Adelaide homes. To help maintain the health of your split system, you can do some of the following:
- Open the lid of your indoor unit and remove the system’s filters.
- Wipe/hose down your filters and let them dry properly before reinserting them into the unit.
- While the lid is still up, use a dry cloth or vacuum cleaner to remove any dust gently.
- Remove dust outside your indoor unit and louvres with a dry cloth or vacuum cleaner.
- For the outdoor unit, try to check up on it regularly to make sure there are no tree branches, plants, leaves or dirt accumulated over the fan. It’s also essential to ensure that the unit has enough space to breathe correctly. Avoid crowding the outdoor unit as this can impede airflow and prevent the system from working correctly.
Ducted air conditioning units
Ducted air conditioning is a great way to cool your entire home evenly and efficiently. If you have a ducted system, you can take the following steps to help keep your system in good condition:
- Loosen the screw/knob on the return rack to take the filter out.
- Hose the filter and let it dry thoroughly before reinserting it back into the rack.
- Check the outdoor unit regularly and remove any leaves or dirt that might be close or accumulated on the unit and fan.
- Ensure the unit always has enough space to breathe and avoid overheating.
Evaporative systems
Evaporative air conditioners are complex and require the expertise of a professional technician to maintain correctly. As such, it is recommended that you only allow an expert to maintain and service your evaporative air conditioner.
Special Care for Daikin Ducted Air Conditioning Maintenance*
Daikin air conditioning systems are renowned for their reliability and energy efficiency. But even the best brands need regular TLC. These air conditioning products require cleaning air filters every two weeks, especially during peak usage, and having the entire system professionally serviced every 1-2 years.
Daikin ducted air conditioning maintenance places a strong emphasis on cleaning both indoor and outdoor coils, performing precise refrigerant charge checks, and calibrating the control system.
Skipping these maintenance and servicing can void warranties and create performance issues, so it pays to let REQ Refrigeration and Air Conditioning handle it. Our certified technicians are trained to service major brands and ensure your system works exactly as designed.
How Often Should You Service Your Air Conditioning Unit?
We get this question a lot. The short answer? Once a year, minimum. But if your household uses the system daily or you have pets and allergies, twice a year is ideal.
In Adelaide’s hot summers and chilly winters, both heating and cooling cycles work hard. Regular servicing maintains system efficiency, avoids sudden breakdowns, and helps keep warranties valid, especially for homeowners using ducted air conditioning systems.
What is the difference between a service done by a professional and by yourself?
A professional HVAC technician will generally check the refrigerant and condenser levels, inspect the condition of pipes, coil, filters, vents, and pads, measure the energy draw, verify airflow on both heating and cooling systems, and clean the outside of the units. The service will also depend on the type of air conditioning unit (evaporative, split, or ducted). However, self-maintenance will enable you to spot an anomaly and detect a potential problem quickly. Regular self-maintenance will also prevent the formation of dirt, grime, and mould, and reduce the overall energy consumption of your unit.
Frequently Asked Questions
What is the $5000 AC rule?
It means if your repair estimate (in dollars) multiplied by the age of your air conditioning unit exceeds $5000, it’s usually better to replace it. For example, a $600 annual repair on a 10-year-old unit equals $6000. In that case, investing in a new unit with higher energy efficiency can save you up to 40% on energy costs (Australian Government’s Energy Rating data). However, minor repairs like replacing a dirty filter or topping up refrigerant levels don’t count here.
What regular maintenance should be done on an air conditioner?
Your air conditioning maintenance service should include cleaning or replacing air filters, checking condenser coils, inspecting refrigerant levels, clearing the external unit, and testing controls. This keeps your air conditioning unit running safely and efficiently.
What happens if you skip air conditioning maintenance?
You risk higher energy costs, more repairs, health issues from poor air quality, and sudden failures. Over time, neglect can reduce system life by up to 50%.
Can I do air conditioning maintenance myself?
You can clean air filters and clear debris from the external unit. But detailed checks on coils, refrigerant levels, and electrical components should be left to qualified pros. Our certified team offers honest advice, transparent pricing, and top-tier maintenance service, whether you have a split system, ducted system, or Daikin ducted air conditioning maintenance needs.
