Ductless Mini-Split Installation questions
Do I need an indoor unit in every room?
Not necessarily, but one unit does not automatically provide even comfort through closed doors or across a complex layout. We review how each room is used and where separate zones make sense.
Where do the refrigerant lines and drains go?
We plan piping and drainage routes during the site visit and explain the visible portions of the installation. Concealment, line covers and condensate pumps are addressed in the written scope when needed.
Can a mini-split be my primary heat source?
A suitable system may serve as primary heating when its capacity and cold-weather performance match the home’s needs. We review the equipment selection and any backup requirements during planning.
What maintenance will the system need?
Filters need routine care, and the system should be inspected and maintained. Indoor deep cleaning is based on buildup and is a separate service. We explain basic care at installation and can help plan ongoing maintenance.
