10 Easy DIY AC Fixes to Try Before Calling a Professional
Is your air conditioning unit not cooling like it used to, or has your AC suddenly stopped working altogether? Before you pick up the phone to call a professional, there are several DIY steps you can take that might solve the problem and save you some money. We believe in empowering homeowners with the knowledge they need to maintain their homes. Here are 10 quick DIY fixes for common air conditioning issues that you can try before calling in experts, like us.
1. Check Your Thermostat Settings
One of the most common air conditioning problems is simple: the thermostat isn’t set correctly. Make sure your thermostat is set to “cool” and that the temperature is lower than the current room temperature. If your HVAC isn’t responding, try replacing the batteries in your thermostat or resetting it by turning it off and then back on. A malfunctioning thermostat can often be why your AC unit isn’t cooling your home properly.
2. Inspect the Circuit Breaker
If your air conditioning unit won’t turn on, the issue might be as simple as a tripped circuit breaker. Locate your home’s breaker panel and check if the switch for your AC has been flipped to the “off” position. If it has, simply switch it back to “on.” If the breaker keeps tripping, it could indicate a deeper electrical issue that requires professional assistance.
3. Replace or Clean the Air Filter
A clogged or dirty air filter is one of the most common reasons for HVAC problems. If your air conditioning unit isn’t cooling effectively or is blowing warm air, check the air filter first. A dirty filter restricts airflow, causing your AC unit to work harder than necessary. Replace the filter with a new one, or if it’s reusable, give it a good clean. It’s recommended to check and replace or clean your air filter every 1-3 months, depending on usage.
4. Clean the Condenser Coils
The condenser coils in your outdoor unit are crucial for proper cooling. Over time, these coils can become covered in dirt, dust, and debris, reducing the efficiency of your AC unit. Turn off the power to your unit, then carefully clean the coils using a garden hose. Make sure not to bend the delicate fins. This simple maintenance task can help improve the performance of your AC and extend its lifespan.
5. Unclog the Condensate Drain Line
A clogged condensate drain line can cause your AC to shut down or even lead to water damage. If you notice water pooling around your indoor unit or a musty smell, it’s time to check the drain line. Use a wet/dry vacuum to remove any blockages. Regularly flushing the line with a mixture of water and vinegar can also help prevent future clogs and keep your AC unit running smoothly.
6. Ensure the Outdoor Unit is Clear of Debris
Your outdoor air conditioning unit needs ample space to operate efficiently. Check around the unit and remove any leaves, grass, or other debris that could be obstructing airflow. It’s recommended to maintain at least two feet of clearance around the entire unit. This ensures proper ventilation and helps prevent your AC from overheating.
7. Inspect Ductwork for Leaks
Leaky ductwork can significantly reduce the efficiency of your HVAC, causing it to work harder to cool your home. While sealing ductwork may require a professional, you can inspect accessible areas for obvious holes or gaps. Temporarily seal any leaks with duct tape until a more permanent solution can be applied.
8. Test and Replace the Capacitor
If your air conditioning unit is humming but the fan isn’t running, you might have a faulty capacitor. This small but essential component helps start the compressor and fan motors. Testing and replacing a capacitor can be done by a confident DIYer, but if you’re unsure, it’s best to call a professional. Capacitors hold an electrical charge, so it’s important to follow safety guidelines when handling them.
9. Reset the Air Conditioning Unit
Sometimes, all your AC unit needs is a simple reset. Turn off the power to the unit, wait a few minutes, and then turn it back on. This can reset the internal systems and clear out any minor glitches that might be causing the problem.
10. Make Sure Vents Are Open and Unblocked
Closed or blocked vents can cause uneven cooling and make your AC unit work harder than necessary. Go around your home and check that all vents are open and unobstructed by furniture, curtains, or other objects. Proper airflow is key to maintaining a comfortable temperature throughout your home.
