Choosing the right air conditioning (AC) unit for your family home can be a daunting task, especially with various options available in the market. The choice comes down to split air con installation or a portable air con unit.

This guide delves into their differences, focusing on running costs, space consumption, efficiency, and effectiveness, to help you make an informed decision.

What is Split Air Con Installation?

It consists of two main parts: an outdoor unit and an indoor unit. The indoor unit is typically mounted on a wall inside the house, while the outdoor unit is placed outside. The indoor unit is sleek and wall-mounted, saving floor space and blending into the room’s decor.

Split air con installation requires a professional heating and cooling engineer to set up both the indoor and outdoor units and connect refrigerant lines and electrical wiring. Once installed, they are a permanent fixture in the home.

What is Portable Air Conditioning?

This is an all-in-one unit with the compressor, condenser, and evaporator housed in a single portable unit that sits on the floor. They can be bulky and require a window venting kit which can be intrusive.

They can be set up without professional help; plug the unit in near a window to vent the hot air outside via the exhaust hose. They can be moved from room to room and do not require permanent installation.

What are the running costs of air con?

Split AC Units: Split AC units generally have lower running costs compared to portable units, especially over long-term use. The cost to run a split AC unit depends on several factors, including the unit’s size, energy efficiency (measured by SEER rating), and usage patterns. Modern split AC units are designed to be energy-efficient, translating to lower electricity bills. On average, the running cost of a split AC unit ranges from £0.15 to £0.30 per hour, depending on the power and efficiency of the model.

Portable AC Units: Portable AC units tend to have higher running costs due to their lower energy efficiency. These units typically consume more power to cool the same space as a split unit. Portable AC units can have an energy efficiency ratio (EER) that is significantly lower than that of split units, resulting in higher electricity consumption. The average running cost of a portable AC unit can range from £0.25 to £0.50 per hour, depending on the model and usage.

How much space does air con use?

Split AC Units: Split AC units are more space-efficient in terms of indoor space. The main components include an outdoor compressor and an indoor air handling unit. The indoor unit is typically mounted high on a wall, freeing up floor space and making it less obtrusive. The outdoor unit requires some space outside the house, but this does not impact the indoor living area.

Portable AC Units: Portable AC units are standalone devices that occupy floor space. They are larger and bulkier compared to the indoor unit of a split AC system. While they offer the advantage of mobility, their size can be a disadvantage in homes with limited space. Additionally, they require a venting system to expel hot air, which usually involves a hose connected to a window, further consuming space and potentially causing inconvenience.

Is split AC or portable AC more efficient?

Split AC Units: Split AC units are renowned for their efficiency and effectiveness. They can cool larger areas more uniformly and maintain a set temperature with greater precision. Split AC systems also come with advanced features like programmable thermostats, air purifiers, and dehumidifiers, enhancing their overall performance and user comfort .

Portable AC Units: Portable AC units, while convenient and easy to install, are generally less efficient. Their cooling capacity is limited, making them suitable for smaller spaces or as a supplementary cooling solution. They often struggle to maintain consistent temperatures and may not cool as uniformly as split units. Their lower EER ratings reflect their reduced energy efficiency compared to split systems.

Which is better: split AC or portable AC?

When choosing between split AC units and portable AC units for a family home, several factors must be considered:

Running Costs: Split AC units have lower long-term running costs due to their higher energy efficiency.

Space Consumption: Split AC units save indoor space with wall-mounted indoor units, whereas portable units occupy floor space and require venting arrangements.

Efficiency and Effectiveness: Split AC units are more efficient and effective, providing better cooling performance for larger areas.

For families looking for a long-term, efficient cooling solution that integrates seamlessly into the home environment, split AC units are often the better choice. However, for those needing a flexible, easy-to-install option for smaller spaces or temporary use, portable AC units may be more appropriate. Assessing your specific needs, space availability, and budget will help you make the best decision for your home.
