Detecting Water Leakage in Your Air Conditioning System

An air conditioner is a vital component of a comfortable home, especially during the sweltering summer months. At Custom Climates HVAC, we understand how essential a well-functioning air conditioning system is to your comfort. However, even the most durable and high-quality units can sometimes encounter issues, with water leakage being among the most common. In this article, we will guide you on detecting air conditioner leaking instances, their reasons and solutions.

Detecting Water Leakage in Your Air Conditioning System

Water leakage in an air conditioning system is not an issue to be ignored. Besides increasing your utility bills, it can lead to more significant problems like mold growth, water damage, and system breakdown if not promptly addressed. But how can you detect water leakage? There are several indicators to look for:

1. Visible Water or Dripping

One of the most apparent signs of a water leak in your air conditioning system is visible water puddles or drips around the unit. Under normal conditions, the air conditioner will produce condensation which gets drained away. However, a leak can result from various issues such as a clogged condensate drain line, a cracked or rusted drain pan, or an improperly installed condensate pump. If you notice water accumulation around your unit, this is a clear indication of a problem, and reaching out to professional air conditioning contractors should be your next step.

2. Increased Humidity

An air conditioner does more than just cool the air; it also dehumidifies it. If your home feels excessively humid despite the air conditioner running, this could indicate an air conditioner leaking issue. High indoor humidity levels can also cause other problems, including mold growth and damage to furniture and electronics. In this scenario, it’s essential to have your air conditioning system checked by professionals.

3. Unusual Sounds

Your air conditioner should run relatively quietly. If you start hearing gurgling noises or sounds of water flowing within your A/C unit, this could be a sign of a leak. These noises are often a result of refrigerant leaks, which can cause bubbling or hissing sounds. It’s not just an indication of water leakage but can also lead to inefficiency in the cooling process and potential damage to the compressor.

4. Mold or Mildew

Unchecked water leaks can lead to the growth of mold or mildew around your A/C unit. This growth doesn’t just harm your unit; it also poses serious health risks, leading to allergies and respiratory problems among the household occupants. If you spot mold or mildew around your air conditioning unit, immediate action is required. It would be best to hire professionals to not only fix the leak but also properly clean and sanitize the affected area.

5. Frozen Coil

The evaporator coil in your air conditioner can freeze due to water leakage. This is often due to a reduced flow of refrigerant, which can be caused by a leak. If your A/C is blowing warm air or has a reduced airflow, it could be due to a frozen coil. Over time, this can cause severe damage to your air conditioning system, including compressor failure.

If you’ve detected any of these signs, don’t hesitate to contact HVAC contractors. At Custom Climates HVAC, we are ready to help and have a team of professionals equipped to tackle any issue your system might be facing.
