Guidelines for Installation of Split AC Units

Man installing an AC unit

The first consideration when getting an AC unit is its type. Split AC units are small, flexible, and ductless. They are ideal for those looking to reduce their energy costs, as the lack of ductwork prevents up to 30% of energy loss.
Professional AC installation in St Charles is advisable to ensure the efficiency and proper functioning of your system. It also prolongs its life, as it prevents unnecessary repair costs. Here are some guidelines on proper installation of your split AC unit:

Ensure that your outdoor unit is placed on a rigid surface

Your outdoor units comprise of the fan, condenser, motor, and compressor, among other components. Units placed on a floppy and uneven surface vibrate excessively. This vibration generates a lot of noise, disturbing you and your neighbors. It can also lead to the breaking of your unit’s copper pipes, condenser or compressor damage, and leakage of the coolant.

Make sure there is a suitable distance between your indoor and outdoor units

A coolant flows through the copper pipes connecting your indoor and outdoor units. During this process, there is some atmospheric loss of the cooling effect of this refrigerant. To minimize this loss, there should be a suitable distance between your indoor and outdoor units. The maximum distance allowed between these units for efficiency is approximately 15 meters.

Ensure the correct location of your units

For maximum efficiency, the indoor and outdoor units should be located away from water and direct sunlight. The outdoor unit should be in an open space. This prevents any obstruction to the heat generated from the unit’s condenser. The indoor unit needs not less than 15cm of free space on its top and sides for proper air flow.

Ensure that the wall you select to install your indoor unit on is strong enough to hold its weight. For adequate cooling, the unit should be 7-8 feet above your floors. The indoor unit should also be slightly tilted to allow unrestricted condensed water flow from the drain pipe.
