Ductless heating
and cooling.
Mini-splits heat and cool rooms without ductwork. They fit homes with no ducts, additions, ADUs, garages and the hot room the central system never reaches.
No ducts needed
A small line set connects each head to the outdoor unit through a wall opening, so there is no duct work to run.
Single or multi-zone
One outdoor unit can serve one room or several, depending on the layout and loads.
Head placement
Wall, ceiling cassette or concealed ducted heads, chosen around furniture, windows and looks.
Electrical and condensate
Dedicated circuit, disconnect and a clean condensate route planned before the install.
Permits
Mechanical and electrical permits and the city inspection handled by HAXX.

GOOD TO KNOW
Ductless Mini-Split Installation in Vallejo: questions, answered.
Do mini-splits work in Vallejo Victorians?
They are often the best fit. Small indoor heads and thin line sets avoid running ducts through original walls.
Does a mini-split need a permit in Vallejo?
Yes. HVAC systems require a City of Vallejo permit. HAXX files it and handles the inspection.
Can a mini-split heat my whole house?
Often, yes, with a multi-zone system or several heads. A load calculation shows how many zones a home needs.
How long does a mini-split install take?
A single-zone system is often one day. Multi-zone systems typically take two to three days.
