How many heads can one outdoor unit run?

Multi-zone units commonly run two to five heads, depending on the model.

Can a mini-split heat a basement suite?

Yes, if it's sized for the space and the suite is reasonably insulated.

An outdoor unit connects to one or more indoor heads through a small line set. Each head has its own controls.

Homes with baseboard heat, basement suites, additions, garages turned into living space and rooms that never feel comfortable.

A separate head or system for a secondary suite lets each household set its own temperature.

Many homeowners use mini-splits to cut back on electric baseboard heating while adding cooling.

Heads go high on walls with clear airflow across the room. Outdoor units need space and a stable base.

Line set covers on outside walls protect the insulation and look tidier.

Wash the indoor filters every few weeks in heavy use, and have the coils cleaned if a musty smell appears.

Indoor heads run quietly, which suits bedrooms and offices.

Townhouses and condos usually need strata approval before installing an outdoor unit.

Tell the contractor which rooms you want to heat and cool. Send a request and an HVAC contractor will get in touch.

Many mini-splits are rated to heat well in cold weather. Ask about low-temperature performance for rooms that need reliable winter heat.

Each head has its own remote, and many can be controlled by phone, which makes it easy to heat only the rooms you use.

Keep tall furniture and curtains from blocking the airflow from each head.
