Ductless Mini-Split Systems in Centennial, CO
Heating and cooling for homes without ductwork, finished attics, additions and rooms that never get comfortable.
Ductless Mini-Split Systems in Centennial
Many Centennial homes built before the 1950s heat with radiators or have limited ductwork, which makes central air hard to add. Ductless mini-splits mount an indoor head on the wall and connect to a small outdoor unit through a few-inch hole. They work well for bungalows, pop-tops, finished attics, basements and garage conversions.

Questions homeowners ask
Can a mini-split heat my home in winter?
Cold-climate mini-splits can provide much of a home's heat in Centennial. Many homeowners keep the existing boiler or furnace as backup.
How many zones do I need?
It depends on the layout. Open floor plans may need one or two heads, while closed-off rooms often need their own.
Do mini-splits need maintenance?
Yes. Clean the indoor filters regularly and have the system serviced periodically, especially the outdoor coil.
