Air conditioning units are essential in keeping our homes and offices cool and comfortable during the hot summer months. However, choosing the right location for your air conditioning unit is just as important as selecting the right unit for your needs. Kent Air Conditioning’s experts can help you choose the best location for your unit by considering the factors discussed below.

Indoor vs outdoor units

First, it is essential to determine whether your air conditioning unit will be located indoors or outdoors. Most central and split air conditioning systems have an outdoor unit that houses the compressor and condenser. In contrast, smaller window or portable air conditioning units are placed inside the room being cooled.

Outdoor units are generally louder than indoor ones, which may make them less desirable if you live in a noise-sensitive area. Outdoor units are also more susceptible to damage from the elements, such as snow, wind and rain. If you live in a place prone to harsh weather conditions, protecting your outdoor unit is essential.

Accessibility

Another factor to take into account when choosing the best location for your air conditioning unit is accessibility. Your unit will require periodic maintenance, such as filter changes and system inspections, so it is essential to choose a location where maintenance can be carried out easily.

If your unit is located in an area that is difficult to access, repairs may take longer and be more expensive. For example, if your unit is located on the roof of your home or office building, it may require a special lift or crane to access, which can add to the cost of repairs.

Airflow

The airflow around your air conditioning unit is crucial to its efficiency and effectiveness. If your unit is located in an area with poor airflow, it will have to work harder to cool the air, which could lead to higher electricity costs and a shorter lifespan for your unit.

When choosing a location for your air conditioning unit, make sure there is adequate airflow around it. As a general guide, allow at least two feet (around 60cm) of space on all sides of the unit and at least five feet (around 1.5m) of clearance above it — always following the manufacturer’s own clearance requirements. The unit should also be located away from obstructions, such as trees, bushes or walls, that could impede airflow.

Sun exposure

The amount of sun exposure your air conditioning unit receives can also affect its efficiency and effectiveness. If your unit sits in direct sunlight, it will have to work harder to cool the air, which could result in higher electricity costs and a shorter lifespan for your unit.

When choosing a location for your air conditioning unit, consider the amount of sun exposure it will receive throughout the day. Ideally, your unit should be in a shady area with minimal direct sunlight.

Noise

As mentioned earlier, outdoor air conditioning units can be quite noisy. If your unit is close to your neighbour’s home or office, choose a location farther away from their property to minimise noise complaints.

If your unit is located near a bedroom or another quiet area, consider a quieter unit or soundproofing the area around your outdoor unit to reduce noise levels.

Choosing your AC location: a summary

Choosing the best location for your air conditioning unit is essential to ensure that it operates efficiently, effectively and with minimal noise. When choosing a location, consider factors such as accessibility, airflow, sun exposure and noise. By choosing carefully, you can ensure that your air conditioning unit provides the cool and comfortable environment you need throughout the summer.
