Troubleshooting A Few Of The More Common HVAC Issues

Posted on: 16 August 2023

Problems with the heating, ventilation, and air conditioning system can be infuriating because a comfortable interior climate is so important. By understanding the most common AC issues, you will be better equipped to troubleshoot your HVAC system or seek professional assistance.

What Are The Signs Of A Refrigerant Leak?

The refrigerant in your air conditioner is essential to its ability to chill the air. A refrigerant leak occurs when this substance is lost from the system. Detecting a refrigerant leak early on is crucial for preventing further damage to your HVAC unit. While the most common sign of a refrigerant leak is pooling fluid near the unit's base, it is important to distinguish refrigerant from condensation. This can be particularly difficult when the liquid leaks onto the ground, as the soil could make it difficult to determine its color. Placing a piece of white paper where the fluid is leaking can make it easier to determine its color.

Repairing a refrigerant leak requires professional expertise because it involves identifying the source of the leak and sealing it properly. These repairs could range from applying a patch to replacing entire components.

What Causes An AC Unit To Freeze Up?

An air conditioning unit freezing up disrupts comfort and indicates an underlying issue within the system. If this issue is not properly handled, it could lead to the system suffering a rupture or other catastrophic failure.

Several factors contribute to an AC unit freezing up. These can include restricted airflow due to clogged filters, blocked vents to low refrigerant levels, or malfunctioning components like blower motors. Thawing a frozen AC unit is crucial to avoid further damage. Increasing ventilation for the frozen coils can help speed up this process. However, you should avoid pouring hot water on it. The sudden temperature change could cause the frozen coils to rupture.

What Should You Do If Your Condenser Fan Stops Spinning?

The condenser fan is vital in heat dissipation from your HVAC system's outdoor unit. A non-spinning condenser fan can result from various issues, such as motor failure, electrical problems, debris accumulation, or faulty capacitors. Identifying the source of this problem may require taking apart the unit's casing. This can be an involved step, but it is essential for providing you with an accurate assessment of the problem.

Repairing or replacing a damaged condenser fan depends on the severity of the issue. Although the cost to replace this part may be higher, doing so might greatly increase the longevity of your system. Contact an AC repair service near you to learn more.
