When you’re getting ready to install a new indoor unit or outdoor unit, you must do your research ahead of time. While an efficient HVAC system can benefit homeowners, you want to make sure your ductwork is up to par. However, if your ductwork isn’t in the best shape, you might want to consider a ductless system.

As the name implies, a ductless system doesn’t rely directly on ducts to move central air throughout the house. A ductless system also referred to as a ductless mini-split system, can be a wonderful addition to any home. Here’s what you need to know before you get started.

How does a ductless HVAC system work?


Before you choose a ductless HVAC system, it’s important to know how it’ll work with your existing ducts and the rest of your home. Unlike a standard air conditioner or HVAC, a ductless HVAC system links indoor units with an outdoor unit or compressor. The indoor units then pull in warm air and return it as cold air. This is because the ductless mini-split system places small units within several rooms to cool the air. If you’ve been looking for an affordable alternative to central air, you may want to consider a ductless mini-split system.

The installation is less intrusive, as well. Homeowners can save a bit of money by choosing a mini-split over traditional air conditioning or another form of the air handler. Since a ductless HVAC system doesn’t require extensive work with your existing ducts and structure, it’s much easier to get a mini-split system in place that can work more effectively than most other indoor air handlers and air systems. On top of that, mini-split systems offer some key benefits that are worth considering.

What are the benefits of ductless air conditioners?

Ductless air conditioners aren’t a modern fad. In fact, by choosing a ductless air conditioner, you’re investing in some solid cost-saving potential. This is because, in a ductless mini-split, the ductless air conditioner installation is much less intrusive, which requires a smaller upfront expense. Especially for contractors in the United States, some technicians may even recommend the split because ductless units can save customers on upfront costs while still installing the right indoor air-handling units for each room.

On top of that, a mini-split system often boasts more energy efficiency than a traditional central air conditioner. If you use the right filters in your mini-split system, your HVAC can operate at peak performance for quite a while. The energy efficiency makes the ductless AC system the best option for many homeowners, especially compared to window AC units that don’t blend well and noisy central air conditioners. Plus, if you ever need to add an air handler to a different room, it’s easy to upgrade when the time is right.

Finding a ductless mini-split technician doesn’t have to be difficult.


Whether you’re preparing for a brand-new mini split installation process or you’re replacing an existing system, you’re going to want to choose contractors who are efficient, effective, and provide value. Discuss the options for your ductless mini with the technicians, and see if there are also maintenance packages to cover your ductless air and heating systems together. It’s also a good idea to ask about any other home additions, such as smart thermostats, that can improve your seasonal energy efficiency ratio and help you save on energy costs. Ask other homeowners in the neighborhood for referrals or turn to your friends and family. This will help you find the right ductless mini-split technician for your needs.

Between fending off allergens, pollen, and moisture to providing cool air throughout the home, a split system offers some key benefits. Instead of a single outdoor unit connected to a network of ducts or a window air conditioner, consider a mini-split. The mini-split has numerous applications, and you’ll be glad you gave it a look.
