How to Heat and Cool a New Addition on Your House That’s Without Ductwork 

Whether you add a sunroom, family room or other space to your house, being comfy in your new room throughout the year is important. However, they can present a unique situation for comfort. This is because installing ductwork is costly. And that your heating and cooling system may not be able to handle the higher load, because it was sized without including the addition. 

One of the most affordable options is to add a mini-split. This system provides energy-efficient heating and cooling, with no ductwork needed. Learn more about mini-splits and how getting one for your addition might be a good fit. 

All About Mini-Splits and How They Heat and Cool 

A ductless mini-split, since they’re very similar to ducted heat pumps that southern homeowners have relied on for decades. 

Heat pumps are highly energy efficient since they transfer heat to make your space comfier. In fact, many have achieved ENERGY STAR® certification, which can make you eligible for added rebates and decrease your utility costs for many years. 

Another unique feature involves zoned heating and cooling. Because each room often has an individual indoor unit, you can choose your preferred temperature from room to room. For example, a mini-split AC is particularly useful if you have a room with precise temperature needs, like a home gym. 

Why a Mini-Split is Worth It for Your Room 

Installing a mini-split system is worth it for spaces that lack ductwork. Here are several reasons why it’s smarter than installing ductwork and relying on your current heating and cooling system. 

1. Installing ductwork is expensive. Adding ductwork in your new addition can be costly. Although the total amount will depend on your home, it run thousands of dollars. 

2. Your current home comfort system could become overwhelmed. When your current heating and cooling system was chosen, it was based on the square footage of your house in advance of the addition. This could overwhelm your system and make it fail more quickly. 

3. Your comfort might decrease. Since your heating and cooling system is sized for specific square footage, your comfort could be reduced if your system is forced to manage a bigger space. Your heating and cooling could be less efficient, and your utility costs could get more expensive due to the system needing to operate more often. 

What Size Mini-Split You Need 

Like regular systems, mini-splits are available in varying sizes based on the square footage they’ll be heating and cooling. Here are three of the most popular sizes: 

• 400-650 square feet – 12,000 BTU mini-split 
• 600-1,000 square feet – 18,000 BTU mini-split 

• 800-1,300 square feet – 24,000 BTU mini-split
