6 Methods To Cool Down a New Home Addition


When a house grows in size, it’s not just about adding square footage but ensuring the new space maintains the same comfort as the rest of the home. A key consideration is how to extend air conditioning to the expansion, especially when no existing ductwork is present. Thankfully, there are several effective solutions, each with distinct advantages and disadvantages.

Ductless Mini-Split Systems

Ductless mini-split systems have emerged as a popular solution in recent times. These systems are composed of an exterior compressor or condenser linked to one or several indoor air-handling units. They are praised for their energy efficiency, often leading to noticeable savings on electricity bills. Furthermore, they offer the luxury of zoned cooling, giving homeowners the flexibility to decide which areas to cool at any given time. 

On the downside, these systems demand regular upkeep to ensure they operate at their best. It should be no more work than having a traditional central air conditioner though, and the maintenance can be done at the same time. In addition, the indoor units might disrupt the aesthetics of the room, which can be unappealing for some homeowners. 

Window Air Conditioners

Window air conditioners are a classic choice, fitting neatly into a window frame and providing cool air for years. One of their standout features is the simplicity of their installation, coupled with the fact that they can be repositioned if required. They’re most effective when cooling individual rooms or smaller areas. 

However, they come with two significant drawbacks: they can obscure beautiful window views and often aren’t as energy-efficient as more contemporary cooling solutions.

Portable Air Conditioners

As the name suggests, portable air conditioners are standalone units designed to be versatile, cooling a room without any permanent installation. Their chief advantage is their mobility, allowing homeowners to transfer the unit to different spaces as the need arises. Additionally, they preserve window views. 

Be aware that portable air conditioners are often louder than other cooling options and still require a window placement for the exhaust hose, which isn’t always aesthetically pleasing.

Ceiling Fans and Ventilation

Ceiling fans offer a different approach to cooling. Although they don’t reduce the actual temperature, they circulate air, which creates a cooler feeling. They are more energy-efficient than many traditional air conditioners and can work in tandem with other cooling systems for better comfort.

Their limitations become apparent during extremely hot days when the cooling effect of air circulation may not be sufficient to combat overwhelming heat.

Evaporative Coolers

Evaporative coolers, or swamp coolers as some call them, function by evaporating water to decrease room temperature. They’re particularly energy-efficient and have the added benefit of introducing moisture to the air, making them ideal for drier climates. However, they do need a consistent water source and tend to be less effective in humid conditions.

Central Air Conditioning Expansion

For those homes already equipped with a central air conditioning system, there’s the option of expanding it to cover the new addition. This ensures uniform cooling throughout the property and can be more economical over time since it leverages an existing setup. 

Unfortunately, this isn’t a simple plug-and-play solution. Extending the system is often intricate and mandates professional expertise. Plus, there’s always the chance the current system might not be powerful enough to accommodate the added load, leading to potential upgrades.

Selecting the right cooling method involves considering each solution’s pros and cons against individual needs, spatial constraints, and budgetary limits. Engaging with HVAC experts like Steele Brothers Heating Inc can provide valuable insights, ensuring that the chosen strategy brings both comfort and efficiency. Adding air conditioning to a home expansion without ductwork may seem challenging initially, but with the myriad of options available, a cool and comfortable living space is attainable.
