How Does a Mini Split Work?
It’s simple physics—heat will always transfer to cold. Using something called an inverter, the mini split is capable of capturing heat through a cold line of refrigerant and moving it to the desired location.

In the summer, the heat is extracted from the air in the house and dumped outside, making it cold. In the winter, heat is scavenged from the outside and pushed back into the house. This creates heating and cooling year-round.

Because there are no ducts to retrofit, the system is simple for a pro to install. And it provides excellent dehumidification, quiet operation, and great efficiency. Need to adjust the temperature or turn the unit off? Just use the remote control.

How Much Space Can a Mini Split Cool?
A single air handler can heat or cool up to 1,000 square feet, depending on the climate and system size. (In heating mode, it functions down to minus 13 degrees F, not a problem where you live.)

For larger spaces, up to four independently controlled indoor units can connect to one condenser, for the ultimate in zoned comfort.

Time: 4-6 hours
Cost: $2,000 - $15,000
Skill Level: Professional

Where to find it?
Richard installed a 12,000 BTU SEER Ductless Mini Split Heat Pump System [https://amzn.to/2NzrgYz], which is manufactured by LG (https://lghvac.com/home).

Installing a mini split is an involved process, so Richard recruited the help of Boston Standard Plumbing for the installation (https://www.bostonstandardplumbing.com/).
