Why Air Conditioning Maintenance Matters

When the weather gets hot, the last thing you want is for your air conditioner to stop working. Regular maintenance keeps your unit in good shape. It helps your system last longer, work better, and even saves you money on energy bills. By learning a little about how your air conditioner works, you can take steps to keep it running when you need it most.

Filters

Filters are important for clean indoor air, but they’re often forgotten. They trap dust, pollen, and other particles, which can clog them over time. Check and clean your filters every month. Replace them every 6 to 12 months, depending on how often you use your air conditioner.

Compressors

The compressor is like the heart of your air conditioner. It moves refrigerant through the system to cool the air. However, compressors can fail due to electrical issues or overheating. Replacing a compressor can be expensive, so make sure the area around the outdoor unit is clear of debris. This allows proper airflow and prevents overheating.

Condenser Coils

Condenser coils release heat from your home to the outside. Over time, they can get dirty, which makes them less effective. During routine maintenance, ask your technician to inspect and clean the coils if needed. This helps your system work better.

Evaporator Coils

Evaporator coils are just like Condenser Coils and help cool the air. If they get dirty or freeze, your system may not work as well, and your energy bills could go up. Have your technician check and clean these coils once a year to keep your air conditioner running efficiently.

Thermostats (Sensors)

Thermostats, or sensors, control the temperature by telling your air conditioner when to turn on or off. Over time, they can stop working properly, causing uneven temperatures and higher energy costs. Replacing a faulty thermostat is usually affordable and can improve comfort while lowering your bills.

Fan Blowers and Fan Decks

Fan blowers and Fan Decks move air through your home or office. If the fan motor breaks, your air conditioner won’t cool effectively. This might tempt you to lower the temperature or increase the fan speed, which can strain the system. Regular maintenance can catch problems early and save you money on repairs..

Refrigerant

Refrigerant isn’t a part you replace, but it’s essential for cooling. Leaks can cause refrigerant levels to drop, reducing efficiency and possibly damaging the compressor. In Australia’s hot summers, it’s important to check refrigerant levels during maintenance. Unusual noises could also signal a problem, so don’t ignore them.

Final Thoughts

Taking care of your air conditioner is key to keeping it reliable and cost-effective. By knowing which parts are most likely to fail and scheduling regular maintenance, you can extend the life of your system. This ensures your home or office stays cool and comfortable when you need it most.
