5 Common Causes of Air Conditioner Water Leaks

Dealing with an AC unit malfunction can be one of the most stressful experiences for homeowners. With temperatures rising and the summer season approaching, now’s the time to recognize issues like air conditioner water leaks, which are becoming increasingly common. Tri-R Mechanical is a reliable and trustworthy air conditioning contractor in Bradenton, FL, that specializes in resolving issues related to your home’s air conditioners. By familiarizing yourself with five of the most common causes of air conditioner water leaks, you can better prepare yourself for what may come.

Common Cause 1: Drainage System Blockages

The drainage system of your AC unit, which is responsible for draining away excess moisture from the condenser coil, can become blocked due to debris or dirt buildup over time. This will impede the water from properly draining and cause it to accumulate inside your AC unit, resulting in air conditioner water leaks and other issues. To avoid this, regular inspections and maintenance should be conducted to ensure no blockages are present.

Common Cause 2: Clogged or Punctured Condensate Line

A clogged or punctured condensate line can also lead to air conditioner water leaks if it’s not correctly maintained or repaired over time. This tube carries water from inside the AC unit, so if any damage is done, it won’t be able to properly transport moisture away, causing it to back up and someday leak out from the system itself. Regular inspections can help identify these issues before they develop into more severe problems down the line.

Common Cause 3: Restricted Air Flow

One common cause for air conditioner water leaks is restricted airflow caused by parts such as a dirty filter or coils becoming clogged due to dust particles and pet hair. This can prevent proper ventilation within your unit, significantly affecting its performance and increasing humidity levels, leading to possible leaking from inside your AC system. Regular maintenance checks should be conducted at least twice yearly to avoid such instances. All filters should be changed depending on usage requirements and ensure that all fans are running smoothly without any obstructions in their paths.

Common Cause 4: Faulty Float Switches

A faulty float switch can be a common issue leading to water leaks in your air conditioner, which can be easily prevented with regular maintenance and servicing. To avoid the risk of AC water leaks and potential damage to your home, our professional technician will check your AC unit. Don’t wait until it’s too late; schedule an appointment with us for AC replacement in Bradenton, FL, to keep your system in top condition and prevent any future issues with your float switch.

Common Cause 5: Poor Installation Practices

This could include improper wiring or incorrect fitting of components, which can cause leaks over time.
