What is a Sunroom?

A sunroom is a greenhouse-like area in the property where you can sit and relax while soaking up natural light. Sunrooms have become increasingly popular over the years as more people value natural aesthetics in the home. These rooms are also available in commercial areas, such as malls, restaurants, and resorts.

There are two reasons to place an air conditioning unit in a sunroom: one is to keep the sunroom warm during winter time, where the sunroom may have plants and vegetation that are sensitive to the cold, the second reason is to keep the room cool, as sunrooms take in direct sunlight, which can greatly warm the room.

Factors to Consider

Space Requirements

Most sunrooms are relatively small rooms, spanning from 100 square feet to around 500 square feet for bigger sunrooms. The type, model, and cooling capacity of your air conditioner must match the space requirements needed to effectively condition the air indoors.

Space is especially important in choosing your cooling options as sunrooms tend to get particularly warm during summer months. Sunrooms are exposed to direct sunlight, increasing the temperature of the room as well, so you will need to take this factor into account when purchasing an air conditioning system.

Heating and Cooling Options

Sunrooms get warm during the day, and cool at night. The indoor temperature also changes throughout the seasons, making it a challenge to install an appropriate air conditioning system. Consider purchasing a ductless mini split system, or window air conditioners that have heating and cooling options to optimize your unit.

Type of Air Conditioning Unit

There are multiple types of air conditioning systems to choose from depending on the space requirements and available area in your sunroom. From a window air conditioning unit to a ductless mini split system, there are various brands and options for your ideal cooling solution.

You should, however, optimize the space and efficiency of the AC unit. For instance, a portable heating and cooling system may be convenient to move from place to place, but they take up much-needed floor space. Similarly, your sunroom may not have sturdy space to install wall-mounted or ceiling-mounted systems.

Energy Efficient

Because your heating and cooling system will be opposing the outdoor temperature, you will need a more powerful unit to efficiently warm or cool your sunroom. This often translates to higher energy bills and electricity consumption, but inverter models, and energy efficient systems with separate thermostat can help minimize the costs.
