Ductless vs Central AC: What’s Right for Your Idaho Falls Home?

Thinking about upgrading your cooling system? If you’ve been searching for ductless air conditioning Idaho Falls, you’re not alone. Many local homeowners are exploring energy-efficient alternatives to traditional central air. But which one is truly right for your home?

Let’s break it down—clearly and simply.

What Is a Ductless AC System?

Also known as a mini-split system, ductless air conditioning delivers cooling (and often heating) without the need for ductwork. It includes an indoor air-handling unit and an outdoor compressor, connected by a small line.

It’s ideal for older homes, additions, or any space without existing ducts.

What Is Central Air Conditioning?

Central AC uses a large outdoor unit that cools air and pushes it through a network of ducts into each room. It’s commonly installed in homes built with ductwork already in place.

Key Differences: Ductless vs Central AC

Pros of Ductless Air Conditioning in Idaho Falls

• No ducts required – Great for older or smaller homes

• Lower energy bills – Only cool the rooms you use

• Fast installation – Usually done in a day

• Dual-purpose – Many models offer heating too

• Quiet operation – Much quieter than window units

Pros of Central Air for Idaho Falls Homes

• Great for large homes – One system cools the whole space

• Sleek look – No visible indoor units

• Tied into home value – Seen as standard in newer homes

• Can work with smart thermostats – Optimize comfort and savings

Which One Is More Energy Efficient?

Hands down, ductless AC is more efficient when used correctly. It avoids duct losses (which can waste up to 30% of cooling power) and allows room-by-room temperature control. That means less wasted energy—and lower monthly bills.

When to Choose Ductless AC

• You’re adding a new room or garage apartment

• Your home doesn’t have ducts and retrofitting is expensive

• You want to cool only certain rooms

• You care about maximizing energy efficiency
