Expert Tips for Maintaining Your AC Unit

As an expert in the HVAC industry, I have encountered numerous air conditioning problems. From malfunctioning parts to dirty filters, there are a variety of issues that can cause an AC unit to fail. However, with proper maintenance and a few simple tips, you can avoid these common problems and keep your AC running smoothly all year round. One of the main reasons people experience issues with their air conditioning is because they neglect to change the air filter. This is a simple and inexpensive task that can prevent major problems down the line.

A dirty filter restricts airflow, causing the evaporator coil to get too cold and freeze the system. To avoid this, it's important to change your filter monthly. Another common issue with central air conditioning is when rooms are closed off, interrupting the airflow throughout the house. On the other hand, if you have an AC unit in a specific room, it's important to close all windows and outside doors to isolate the room from the rest of the house. For a comprehensive list of common AC problems and how to address them, check out our Energy Saver 101 infographic on home cooling. In addition to neglecting maintenance tasks like changing filters, many AC problems are also caused by faulty installation or inadequate service procedures.

Improper installation can lead to duct leaks and low airflow, while an incorrect coolant charge can affect the performance and efficiency of the unit. It's important to hire a qualified technician who will properly install and maintain your AC unit. If your AC unit is low on refrigerant, it's likely due to a leak that needs to be repaired. Simply adding more coolant won't solve the problem. A trained technician must repair any leaks and then charge the system with the correct amount of coolant.

It's important to note that the performance and efficiency of your AC unit are best when the refrigerant charge matches the manufacturer's specifications exactly. In addition to causing problems with your AC unit, refrigerant leaks can also be harmful to the environment. If you notice a foul smell coming from your unit, it could be a sign of mold, fungus, or a burnt cable. These issues require immediate attention from a professional technician. While air filters may not seem like an important part of an AC unit, they are crucial for its proper functioning. We recommend that homeowners do not attempt to clean or replace filters themselves, as this should be done by a trained professional with the unit turned off.

Keeping your filters clean can increase your AC's capacity and efficiency, saving you money in the long run. Dust and other particles can also accumulate in the condensing coil of an AC unit, reducing its efficiency and capacity. This is why it's important to have regular maintenance visits from a professional HVAC technician. They can clean the coils and ensure that your AC is running at its best. If you have any questions or concerns about your AC unit, don't hesitate to contact a professional HVAC company like Wyckoff Heating & Cooling. It's important to address any issues or repairs promptly to avoid further damage and costly repairs down the line.
