The Pros and Cons of Wall-Mounted HVAC Units

As temperatures rise in the summer months, homeowners are faced with the decision of how to keep their homes cool and comfortable. While central air conditioning units are a popular choice, they can be expensive and require extensive installation. Wall-mounted air conditioners (also called mini splits) have become an increasingly popular alternative due to their ease of installation and affordability.

However, before investing in a wall-mounted air conditioner, it’s important to consider whether or not it’s the best option for your home. Factors such as room size, insulation, and budget should be taken into account, along with the following pros and cons of wall-mounted HVAC units.

Pro: They’re Inexpensive

Compared to central air conditioning systems, wall-mounted ACs are relatively inexpensive and easy to install. On average, a mini split installation costs about $3,000, including the cost of the unit and labor. This cost can go up or down depending on things like the unit’s manufacturer and the extent of the work required.

Still, there are significant cost savings compared to traditional ductwork, which can cost as much as $20 per linear foot.

Con: They Don’t Cool Your Whole Home

Wall-mounted ACs are designed to cool small spaces, such as a sunroom or single bedroom. They’re not designed for high-volume cooling, so only a small space in your home will benefit. They’re most common in rooms that don’t have existing ductwork. For example, if you converted a car port into a fully enclosed room, you might consider adding a mini split instead of running new ductwork.

Pro: They Give You More Cooling Control

Mini splits are ideal for rooms that you don’t use often (and therefore don’t need to cool all the time). Because they’re not connected to existing ductwork, you’re not spending money and energy cooling rooms you’re not using.

When you do need to use those rooms, your mini split can quickly cool the space since that’s its only job.

Con: They Could Create Drafts

Your mini split will be mounted to the wall and will require a connection to the outdoors. If your unit isn’t properly installed and sealed, it could create unwanted drafts. All that cooled air might go right back outside, leaving rooms feeling hot and stuffy. The best defense against this is to have your units professionally installed by a company with experience in wall-mounted units.

Pro: They’re Super Energy-Efficient

Compared to central AC units, wall-mounted units can save on energy and costs. They naturally use less energy, especially since they’re not working to cool your entire home. In fact, Energy Star-certified units use as much as 60% less energy!

Con: Wall Units Require Maintenance, Too

Homeowners will need to maintain their wall-mounted units, including changing air filters, checking hoses, and cleaning coils. Your installer can also conduct routine service on your behalf.
