Poor Installation

If your unit is newer and it starts to leak, the original installation is likely the culprit. It’s possible that the installer failed to level the ground where the unit is installed or there’s insufficient drainage. Misaligned parts or loose connections could also lead to leaks.

How to Fix

If you suspect that poor installation is causing your AC to leak, it’s best to contact a professional HVAC technician. They can inspect the entire system, identify installation errors, and make the necessary adjustments or repairs to ensure proper operation and prevent future leaks.

Clogged Drain Line

The drain line moves condensation away from your home and the unit. If it’s clogged, that water has nowhere to go and can flow back to the evaporator coil for your air conditioner. All kinds of things can cause a clog, from dirt and dust or other debris.

How to Fix

Addressing a clogged drain line requires careful handling to prevent any further damage to your AC system. Attempting to handle clogged drain lines without proper knowledge and tools not only risks damaging your AC unit but can also lead to costly repairs. For safety and assurance, seeking professional assistance is often the best course of action.

Dirty Air Filters

If you don’t remember to change your air filters on time, they can restrict air flow, which can eventually cause your evaporator coils to freeze. The ice that builds up melts after the AC shuts off, and the water has to go somewhere. Unfortunately, this often means a leaky AC unit.

How to Fix

The fix for this issue is easy: Check your air filter every month, and if it starts to look full, replace it. If your filter is dirty and you see ice built up around the AC lines going into your evaporator coil, you will need to turn the unit off for 24 hours in order to thaw after replacing the filter before you turn the unit back on.

Low Refrigerant Levels

Low refrigerant levels can cause the evaporator coils to get colder and colder with every cycle, resulting in ice buildup. Refrigerant leaks can occur due to damaged refrigerant lines, faulty valves, or improper initial charging.

How to Fix

Contact a licensed HVAC technician to inspect the system for leaks and recharge the refrigerant. Anything involving refrigerant is a job for an HVAC professional or other certified handler.

Incorrectly Sized AC Unit

Using an AC unit that is too large or too small for your space can cause leaks. An oversized unit may short cycle, leading to excess moisture buildup, while an undersized unit may struggle to remove humidity effectively, resulting in water accumulation and leaks.

How to Fix

Unfortunately, this is a very expensive issue to fix since it means installing an entirely new air conditioner. Make sure your new installer does comprehensive load calculations to ensure you get the right AC unit this time.
