The Most Common Cause of AC Unit Problems

As an HVAC expert with years of experience, I have encountered numerous air conditioning units that have failed due to various issues. However, one problem stands out as the most common culprit behind AC unit problems: a leaking refrigerant circuit. The refrigerant circuit is a crucial component of any air conditioning system. It consists of the air conditioner itself, a set of copper refrigeration pipes, and the evaporator coil. When any part of this circuit is damaged or malfunctioning, it can lead to a host of issues that can affect the performance and efficiency of your AC unit. One telltale sign that your AC unit has a leaking refrigerant circuit is if it needs to be refilled with refrigerant every year.

This not only causes inconvenience but also adds up to be a costly expense. If you find yourself constantly needing to refill your AC unit with refrigerant, it's time to take action. There are two options when dealing with a leaking refrigerant circuit: repair or replace. Depending on the extent of the damage and the age of your AC unit, one option may be more feasible than the other. However, it's crucial to address this issue as soon as possible to avoid further damage and expenses. If you choose to repair your AC unit, a professional HVAC technician will need to locate and fix the leak in the refrigerant circuit.

This can be a time-consuming and labor-intensive process, but it will ultimately save you money in the long run. On the other hand, if your AC unit is old and has been experiencing frequent issues, it may be more cost-effective to replace the entire system. A new AC unit will not only solve the problem of a leaking refrigerant circuit but also provide better energy efficiency and performance. It's important to note that a leaking refrigerant circuit is not the only issue that can cause problems with your AC unit. Regular maintenance and upkeep are crucial in ensuring the longevity and efficiency of your system. One simple but often overlooked task is changing the air filters regularly. If you have a central air system, it's recommended to change the filters every 1-3 months, depending on usage and the presence of pets.

Clogged or dirty filters can restrict airflow and put unnecessary strain on your AC unit, leading to potential issues down the line. When it comes to choosing the right size AC unit for your home, it's essential to consider the size of the room or area you want to cool. For a living room or family room, a large 9,800 to 12,500 Btu air conditioner is recommended, especially if you have an open floor plan. In conclusion, a leaking refrigerant circuit is often the main culprit behind AC unit problems. Whether you choose to repair or replace your system, addressing this issue promptly will save you time, money, and headaches in the long run. And don't forget to stay on top of regular maintenance tasks like changing air filters to keep your AC unit running smoothly for years to come.
