Ductless Mini-Split Installation Questions
Can a mini-split heat a whole house?
Multi-zone systems can, especially in smaller or open-plan homes. Larger homes often mix ductless zones with other heat.
Do mini-splits work in winter?
Yes. Most are heat pumps and many are rated to heat well below freezing.
Will I see the indoor units?
Wall units are the most common. Ceiling cassettes and floor units are options when you'd rather not have one high on a wall.
Do you service existing mini-splits?
Yes, including cleaning, error codes and drainage problems.
