Can one outdoor unit serve multiple rooms?

Yes — multi-zone systems connect up to 4–8 indoor heads to a single outdoor condenser, each with independent temperature control. The contractor designs the zone layout during your estimate.

Do mini-splits heat as well as cool?

Yes, they're heat pumps — they both heat and cool. Cold-climate models handle freezing temperatures; in extreme cold regions they're often a supplement to a primary heating system rather than a whole-home replacement.

How disruptive is mini-split installation?

Far less than adding ductwork: a 3-inch line set connects the indoor and outdoor units through the wall. Most single-zone installations finish in a day with no major construction.

How do I maintain a ductless mini-split?

Clean the indoor filters monthly — they slide out and rinse clean. Keep the outdoor unit clear of debris and vegetation, and schedule professional service annually to check refrigerant charge and electrical components.

Are installation estimates free?

Yes — in-home mini-split estimates are free with most independent contractors in our network, including zone design recommendations.

How does the Massachusetts climate affect ductless mini-split installation in Boston?

Massachusetts requires licensed contractors and local permits; Mass Save rebates influence many replacements.
