5 Essential Air Conditioning Maintenance Tips for Homeowners

Ever wondered why your air conditioning doesn’t seem to be as efficient as it used to be? Maybe you’ve noticed it’s not cooling your home as quickly, or perhaps your energy bill has crept up. It could be that your air conditioning system needs a bit of attention. Just like any other part of your home, your AC system benefits from regular maintenance to keep things running smoothly. Here, we’ll cover five essential tips to keep your air conditioning in tip-top shape and ensure it works efficiently when you need it most.

1. Clean or Replace Your Filters Regularly

Let’s start with the most basic and often overlooked task—cleaning or replacing the filters. As experts like ProtoCool will confirm, replacing and cleaning your filters makes a huge difference. Over time, dust, dirt, and debris build up in your air filters, restricting airflow and making your system work harder than necessary. This not only reduces efficiency but can also lead to wear and tear.

So, how often should you clean or replace your filters? It depends on the type of filter and the environment in your home. Generally, it’s a good idea to:

• Clean or replace your filters every 1-2 months during peak usage seasons (summer and winter).
• If you have pets or live in a dusty area, you might need to check and clean them more frequently.
• Some high-quality filters last longer, so check your manufacturer’s recommendations for specifics.

Think of this as an easy, quick task that can save you money in the long run.

2. Keep the Coils Clean

The evaporator and condenser coils in your AC play a critical role in its cooling process. Over time, these coils can collect dirt, especially if your air filters haven’t been maintained well. A dirty coil reduces the system’s ability to absorb heat, meaning your air conditioner will struggle to cool your home efficiently.

To keep your coils in good shape:

• Check them at least once a year.
• Clean the coils gently using a soft brush or vacuum, ensuring you don’t damage the delicate fins.
• For an added layer of protection, consider keeping the area around your outdoor unit clear of debris, grass, and leaves.

By keeping these coils clean, you’re not only ensuring that your air conditioning is working efficiently, but you’re also extending the lifespan of the system.

3. Inspect and Clear the Drain Line

Did you know that your air conditioner not only cools your home but also removes moisture from the air? This moisture is collected and drained through a specific pipe called the condensate drain line. Over time, algae, mould, or debris can clog the drain, causing water damage and possibly leading to higher humidity levels in your home.

To prevent this:

• Inspect the drain line periodically for blockages or slow drainage.
• Use a simple mix of bleach and water (or a specialised cleaner) to flush the drain line at least once a year to keep it clear.
• Ensure the line is draining to the outside properly, without pooling water near the foundation of your home.

A clear drain line helps your AC system run efficiently and avoids those annoying water leaks.

4. Check the Thermostat Settings

Have you ever wondered if your thermostat is working as it should? A malfunctioning or poorly set thermostat can significantly affect how well your air conditioner operates. Whether you’re using a traditional or smart thermostat, it’s essential to check the settings regularly to ensure everything is running as expected.

Here are a few things you can do:

• Make sure the thermostat is set to the correct temperature for your comfort, and not too low, which can overwork the system.
• If you have a programmable thermostat, ensure it’s set to a schedule that aligns with when you’re home. This can save you energy and money.
• For smart thermostats, regularly update the software and check for any new features that could improve your system’s efficiency.

This is one of the easiest ways to ensure your air conditioner is operating optimally.

5. Schedule Professional Maintenance Annually

No matter how diligent you are with at-home maintenance, some things require a professional’s touch. Scheduling annual maintenance with a qualified technician can save you a lot of headaches and expenses down the road. During a professional tune-up, the technician will:

• Inspect the entire system for potential issues that you might miss.
• Check refrigerant levels and test for any leaks.
• Examine and clean internal components, ensuring everything is in working order.

Think of this as your system’s yearly health check. An expert can identify problems early on, preventing costly repairs or even the need for a full replacement.

Keep Your Cool

Your air conditioning system is a big investment, and like anything valuable, it needs regular care to keep it performing well. Following these simple maintenance tips can save you money on repairs and energy bills while ensuring your home stays comfortable.
