If you’ve recently noticed water pooling around your air conditioning unit or are experiencing a drop in cooling performance, a leaking evaporator coil could be the culprit. The evaporator coil is a vital component of your AC system, responsible for absorbing heat from indoor air and facilitating the cooling process. When the evaporator coil develops a leak, it not only reduces your comfort but can also cause expensive repairs and decrease the system’s efficiency.

For homeowners and businesses across the UK, recognising the signs of a leaking evaporator coil and knowing how to address the problem is essential. In this blog, we’ll guide you through the causes, effects, and troubleshooting techniques for a leaking AC evaporator coil, helping you maintain a reliable and efficient cooling system.

Understanding the Role of the Evaporator Coil

The evaporator coil sits inside your air conditioning unit, typically near the blower fan. This coil, filled with refrigerant, absorbs heat from the indoor air as warm air passes over it, cooling the air before it is circulated back into your living spaces. This process relies on the coil maintaining a delicate balance of temperature and pressure.

When the coil leaks, refrigerant escapes, moisture can accumulate, and ice may form, disrupting the entire cooling cycle. Think of the evaporator coil as the heart of your AC; if it fails, the whole system struggles to keep your space comfortable.
