What's included in a Split System Service?

Breathe Cleaner, Healthier Air with Specialist Split System Cleaning

Over time, dust, dirt and bacteria can build up inside your air conditioning unit. Without regular professional cleaning, your split system can become a breeding ground for bacteria and mould with indoor air.

Over time, this buildup can circulate through the air you breathe. The most common culprit is a dirty filter — when not cleaned regularly. A dirty system also works harder to maintain temperature, which means higher power consumption and increased electricity bills.

If you often experience a runny nose, asthma, headaches, flu-like symptoms, coughing, or itchy eyes, your air conditioner could be the hidden cause.

At Gastek, we specialise in removing the dust, bacteria and mould that build up inside your air conditioning system — helping you and your family enjoy cleaner, fresher, and healthier air inside your home.
