A mini split AC in Port St. Lucie cools the room the ducts can't reach

The garage you turned into an office is 88 degrees by noon. The addition never cools. A mini split AC in Port St. Lucie homes solves that without running new ductwork.

One outdoor unit, one or more heads on the wall, and that room finally gets its own air.

Additions and garages are where they shine

Converted garages, additions, and rooms far from the air handler starve on a central system. A ductless zone handles that space by itself.

We size the zone, run the line set, and pull permits where they're required.

Existing mini splits get fixed too

If the indoor head is fine and the outdoor unit isn't, we'll say which part failed and give you both numbers.

Two years on labor

Residential installs carry a 2-year labor warranty from us plus the manufacturer's 10-year parts warranty. Financing is available, with approved credit.

What the visit covers

  • Single-zone and multi-zone installs
  • Line set routing and electrical
  • Permits and inspection where required
  • Repair of existing mini splits

York system at a local business, Port St. Lucie

A commercial York system and a wall-mounted mini split at the same business. We serviced the outdoor condensers and the cooling equipment so the place stays cold through August.

Office mini split, sized to the real load, Port St. Lucie

The office had more equipment in it than the original plan assumed. We pulled the permit, ran a heat load calculation on the actual room, and installed a mini split sized to it.

Good to know

What Port St. Lucie homeowners ask us

Additions, garages, offices, and rooms too far from the air handler. We size the zone, run the line set, and pull permits where they're required.
That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.
No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.
Yes. We answer 24/7. Sundays and holidays are billed at double time.
