What is Ductless AC?

March 16, 2022 | Blog

Many different terms get used in the world of AC systems. Today, our team at Ace Air Conditioning & Plumbing wants to help you better understand ductless AC. We will explain what ductless AC systems are and why they may best fit your home throughout this blog.

What Exactly is Ductless AC?

Ductless air conditioning is what it sounds like: a system without ductwork. Ductless systems are perfect if you want to provide heating and cooling in specific areas. These systems operate by having one central system outside and a few wall-mounted systems inside. These systems connect via refrigerant tubing and electrical wiring.

Ductless AC systems can be single or multi-zoned, depending on what you need for your home. These systems are typically quieter than traditional AC units. The outdoor unit can be strategically placed to reduce the noise heard inside.

Ductless vs. Traditional AC

Some homeowners often ask us the key differences between ductless and traditional AC units. While the one obvious answer is one has ductwork, and the other does not, there are many other things to compare when looking at the two. Here are a few things to consider when looking at these systems.

The Size of Your Home

If you have a larger home, ductless AC may not be the right choice for you. While these systems are robust and do well heating and cooling, they may not be powerful enough for your home. Ductless AC units are recommended for homeowners with 2,000 square feet or less. Many homes also do not have the size required for ductwork to be installed.

A ductless unit may be the perfect solution if you have recently added a new addition to your home and are not looking to install ductwork in that area.

Do You Have Existing Ductwork?

If you already have an HVAC system that uses ductwork, sticking with a central system may be more cost-effective. Ductless systems are less costly to install than traditional systems. All the construction required is a 3-inch hole where you would like the indoor unit placed.

Is Energy Efficiency Important to You?

Ductless systems are more energy-efficient, especially when buying a higher-grade model. Because of how these systems are built, they can run with very little energy.

Zone Control

Ductless systems are a no-brainer for some homeowners because of the ability to create zones in their households. This means that you can control the temperature in separate areas of your home.


While ductless and traditional systems require yearly maintenance, ductless AC units require weekly upkeep. Homeowners must be sure to check the air filters of these systems weekly if they are used all year long.

What Our Customers Are Saying

Friendly and Honest

Technician came out to my house within an hour of calling and he was very friendly and honest. I was expecting to have to replace the whole unit or have a salesman try to have me “upgrade” to a newer unit but Mr Jeff was quick to diagnose and correct the problem at a reasonable cost.

Excellent Service!

We called Ace on a Sunday. Several hours later a serviceman arrived, inspected the air conditioner, and got it working. The serviceman was quite knowledgeable. Excellent service!

Highly Recommended

Jace went out of his way to get my air conditioner repaired so that my home would be comfortable for the weekend. He was extremely polite and professional. I highly recommend ACE as a company and Jace as a technician. I could not have been more pleased with the service I received.
