Specialising in commercial and residential ducted air conditioning, we have qualified technicians with over 30 years experience, using top brands such as Panasonic, Mitsubishi Heavy Industries, Daikin and ActronAir.  State of the art technology ensures that we install low maintenance systems that effectively control the climate and provide an environment void of hot and cold spots. Air is circulated through a system of filters that offer cleaner, fresher air. We also provide constant professional monitoring and are committed to reducing your running costs.

A ducted air conditioning system is the ultimate choice for air conditioned comfort in your home or office. You can control the temperature to suit your individual requirements thus making it cost effective and efficient, ultimately saving you money.

Ducting is installed into the roof of your house or office to service the area via ceiling grills. Ducting can also be installed under the floor of your house (subject to access) to service the ground area via floor grills. The ground floor can also be serviced by the roof ducting by running ‘droppers’ from the roof to the ceiling of your ground floor; these droppers can be hidden within wardrobes and be made to look as part of the construction of your house.

Using a ducted air conditioning system to air condition your home or office means there are no bulkhead units to be seen in the home or office, only air grills, and this is all connected to one outdoor unit which is compact and quiet.

If you are in the process of, or thinking of, building or renovating, the best time to contact us for your air conditioning needs is before work starts; this way we can converse with your builder and architect to ensure that your air conditioning system is installed seamlessly into your home or office.

The Inverter tag found on some air conditioners signifies the ability of the unit to continuously regulate its thermal power flow.

Traditional reverse-cycle air-conditioners use a heat pump that is either working at maximum capability or switched off, as the compressor’s speed cannot be varied. In order to regulate temperature a thermistor is used to measure the ambient air temperature and switch the compressor on when the ambient air temperature is too far from the desired temperature.

Air-conditioners bearing the Inverter tag use a rectifier to convert the incoming AC current to DC and then use Pulse-Width Modulation of the DC current within an inverter (electrical) to produce AC current of a desired frequency. As the speed of a brushless motor is synchronised to the frequency of the AC current it is thus possible to build a compressor that can be run at different speeds. A microcontroller can then sample the current ambient air temperature and adjust the speed of the compressor appropriately.

The effect of eliminating stop-start cycles is to increase efficiency, extend the life of components and eliminate sharp fluctuations in the load the air-conditioner places on the power supply.

Single split systems are a popular choice for your air conditioning needs.

A split system can be installed into one room or area of your house. You have a choice of just cooling or cooling and heating, as well as inverter and non-inverter types.

A split system has an indoor unit that is connected to an outdoor unit. These come in different energy sizes depending on your room size and requirements, our technician will advise you at the time of consultation which size would be suitable for your home or office.

A multi split system is a good choice for air conditioned comfort in your home if ducting is not appropriate or not wanted; or indeed if individual room control is desired. You can air condition your entire home with a single outdoor unit.

Multi splits systems are a good choice if you want to individually control the temperature in each room, or you want different types of units in your rooms. You can mix conventional wall mounted split units with ceiling suspended units, bulkhead units, etc.

Nepean Air offers its customers an “Annual Preventative Maintenance” (APM) service to assist in extending the life of your Air Conditioning System. Our fully Qualified Service Technicians will provide you with a comprehensive system service, from wall splits to ducted air conditioning systems.

This is a small price to pay for your peace of mind.

An inefficient air conditioning system lacks performance, wastes power and ultimately your money.

Most manufacturers offer a 5 years part and labour warranty on their products, we recommend that our customers follow their terms and conditions and maintain the system annually.

It’s just like getting your car serviced on a regular basis.
