Regular servicing can dramatically increase the lifespan and efficiency of your air con system. Our routine air conditioning services in Hornsby include:

Cleaning filters and outdoor units

• Dusty filters and debris-covered outdoor units reduce airflow and force your system to work harder, increasing energy use and wear. We offer thorough aircon cleaning services to maintain peak efficiency and ensure healthy air circulation.

Checking refrigerant levels

• Low refrigerant can cause poor cooling performance and damage your compressor over time. Our technicians check and top up refrigerant levels as needed to keep your system running smoothly.

Inspecting electrical components

• Faulty wiring or loose connections can lead to system failures or safety hazards. We inspect all electrical components to identify early signs of wear and prevent future issues.

Assessing airflow and overall system health

• Uneven airflow can mean blocked ducts or failing fans. We evaluate your system’s performance to ensure consistent airflow and long-term reliability.

A proactive approach can help you avoid expensive breakdowns and improve your system’s performance and energy efficiency.

Preventative Maintenance and Cleaning

We offer flexible air conditioning maintenance plans for both residential and commercial clients, covering all your heating and cooling needs. Regular cleaning and inspection help protect your investment, reduce running costs, and ensure healthy air flow throughout your property.
