How long does it take to install a new air conditioning unit?2015-06-04T02:02:32+00:00

Most residential installations of a split system generally take 4-6 hours. The installation of a ducted system generally takes between 1-2 days.

What is the operating cost?2012-11-27T14:44:54+00:00

Reverse cycle air conditioning is the most energy efficient method of heating and/or cooling your home or office. Operating costs are determined by how long the air-conditioning system is running and the size of the area to be conditioned. It is essential that the correct size unit is installed. An undersized unit will be significantly more expensive to run, taking longer to heat or cool the area effectively.

What size unit do I need?2012-11-27T14:44:05+00:00

This is determined by the size of the area, the aspect, whether the home is insulated, the amount of glass and the heat load generated from the number of people occupying the area. Our team at Lopez can visit your home to correctly determine the exact size required, maximising efficiency and minimising energy costs. This is a free service.

What is an inverter air-conditioning system?2012-11-27T14:43:43+00:00

An inverter system uses a variable speed compressor, which allows variation in the cooling or heating capacity of the air conditioning to suit indoor conditions. Inverter units are more economical and efficient to operate. They are also quieter than fixed speed systems. Both ducted and split systems are available with inverter technology.

What is back-to-back installation?2012-11-27T14:43:24+00:00

The indoor and outdoor units are placed on opposite sides of the same wall. This reduces the amount of copper pipe run required to connect the two units ad ultimately reduces the cost of installation.

What does ‘reverse cycle’ and ‘split system’ mean?2012-11-27T14:42:55+00:00

A split system air conditioner comprises two pieces: the outdoor unit, which sits outside your home, and the indoor unit, commonly wall-mounted inside the home.

Reverse cycle means the system can provide both heating and cooling. Multi-head systems, ceiling cassettes, under ceiling units and cooling-only models are available.
