5 Questions to Ask About Installing a Ductless Mini Split

A mini split is an energy-efficient solution for spaces you want to heat and cool without ductwork, such as a home addition or small space. A licensed professional should install a ductless mini split, as the project requires training in electrical work and handling refrigerant. Flow into these five ductless mini split questions you can expect to discuss with a pro.

1. In what room(s) do you want the mini split installed? 

If you’re adding a room to your home or want better temperature control in a certain space, such as a sunroom or a garage, share those details with a pro. Some mini-split systems can heat and cool more than one room using multiple indoor units and a single outdoor unit. Your pro will want to know the approximate square footage as well. 

2. Where is the room located in the home?

Your contractor will ask questions about how easy it is to access the space for electrical work, such as whether they can reach the room from an unused basement or attic, and whether the room is on the first or second floor. Your pro will need to run a separate electrical line directly to your home's electrical panel. You may need to upgrade your electrical service to handle the extra power demand. 

A pro will come out to assess the full scope of the project and any structural barriers. They’ll want to ensure the wall can support the weight of the mini split. They’ll also look for where to install the indoor unit so it’s not too close to a window or in direct sunlight.

3. When do you need the mini split installed? 

If you want your room to be cool for the summer, contact a pro in the spring to get on their calendar. If you’re hoping for a cozy space by fall, reach out to pros in the summer. Getting on a pro's schedule can take a week to several weeks. Contact at least three mini split install pros near you for quotes and to discuss your project timeline.

4. What is your budget for a ductless mini split?

The cost to install a ductless mini split ranges from $2,000 to $14,500, with a national average of $3,000. A multi-zone system costs significantly more than a single-room unit. The size and number of BTUs also impact cost. Talk with mini split installers near you to discuss project expenses. 

5. What other HVAC services do you need? 

While a licensed HVAC pro is on-site for your mini split install, it’s smart to capitalize on the opportunity. Consider other HVAC upgrades you want around your home, such as ductwork cleaning or a furnace inspection. You can save on cost and time by having the pro batch their services.
