We Design, Supply & Install All Types of Air Consitioning Systems

Wall Mounts & Multi Split Systems

Looking for a small, compact, and cost-effective solution? Split system air conditioning is ideal for open plan areas and smaller spaces, such as individual rooms. Wall mounted systems contain two units – the evaporator mounted on the wall inside, and a condenser / compressor outside ensuring quiet operation.

Multi split systems are used to heat or cool multiple rooms using just single outdoor unit which connects to the indoor units. Hills Air can use varying indoor units for your home, including wall mounts, small ducted systems, floor mounted, or bulkhead units. The indoor units can be controlled individually, allowing for different room temperatures and controls.

Ducted Air Conditioning

Ducted air conditioning systems offer climate-controlled comfort throughout the home. New Wi-Fi control technologies allow you to adjust the temperature and airflow in any room from virtually anywhere using your phone or device!

Ducted systems are suitable for single or multi story dwellings. Central air is sent through ducts from one location of the house to the remainder of the house, cooling each room to the required temperature. They consist of an indoor fan unit (evaporator) and an outdoor unit (condenser). Ducted systems are easily concealed, to avoid disrupting the appearance or design of your home. Typically, the indoor unit is hidden in the ceiling roof cavity or under the house.

Residential Preventative Maintenance & Breakdown Service

Residential Maintenance

Hills Air Conditioning provides preventative maintenance and breakdown service for all makes and models of air conditioning systems. A system that is regularly maintained improves air quality, minimizes power consumption – reduces electricity bills, prolongs unit life, and reduces the risk of unexpected costly air conditioning repairs servicing.

Our maintenance service in Sydney ensures your system has maximum operational efficiency. We recommend a service call twice a year, in autumn and spring – to prepare for the cool weather and warmer months.

What our clients have to say

Arranged a service & got the best report on our air conditioner including photos, the technician explained the cost of repair and corrosion in the unit and that it would be better to replace the system, I went ahead with their recommendations for a new Mitsubishi Electric system and WOW its quiet and efficient. As for their workmanship I could not fault it, they arrived on time, even had their own vacuum cleaner and vacuumed up after they had finished, wished all trades personnel were like that! Keep up the good work Hills and will be recommending you.

Ruth King, Paddington

Very professional and meticulous, the installers were a pleasure to work with and we highly recommend them to everyone. They made sure we understood what was going on and instructed on the workings of the system installed.

Tanya Thu, Castle Hill

Great work guys on fixing the A/C temperature issues in my office, my office staff are more than happy.
Also the cleaning of the grilles WOW they look like new certainly will have you back to service it again.
