Split System Air Conditioning Installation

Dunn and Williams supply and install split system air conditioners. Split system ACs are generally cheaper than ducted systems to install due to their more straightforward installation process. Split systems comprise of two units, the inside unit which expells the desired air is installed on the inside wall and the other unit ( compressor) is installed on the opposite side of the same wall.

Advantages of Inverter Control

You may have heard of the term Inverter! But how does this relate to a split system AC? Air conditioners have advanced through the years and an inverter is the new technology used in split system air conditioners. This new technology is more economical, quieter, smoother, and more stable in operation than conventional units. Inverters handle extremes in temperature and reach the desired temperature a lot quicker than conventional air conditioners, which means you can achieve 30% more operating efficiency than conventional models. The way this works is the inverter control component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor, saving you money on the running costs of your system.

Inverter Split Systems offer High Energy Efficiency

One of the many benefits of the high-efficiency DC inverter Multi System is that it provides energy-saving performance, boasting 50% greater efficiency compared to a constant-speed multi-system. Another feature is the enhanced inverter cooling ratio which ensures the capacity remains stable even when operating under heavy load conditions.

Inverter Split Systems offer excellent Comfort and Stability

With inverter control technology your AC will maintain a steady output at the ideal setting. The inverter will make any adjustments needed within the range from maximum to minimum as needed to match the load. Factors that will influence this adjustment include room temperature and the number of people in the room. Additional benefits of a split system air conditioner include:
