Ductless Mini-Splits

Ductless mini-split installation for Florida room additions, garage conversions, casitas, and rooms your central AC just can't reach. Single-zone and multi-zone systems from major brands, installed across the Treasure Coast.

A ductless mini-split is the answer for any space where running ductwork from your central AC isn't practical: a Florida room conversion, a garage you've turned into a home office, a casita or in-law suite, a sunroom that turns into a sauna in July, or a master bedroom that runs ten degrees hotter than the rest of the house. First Aid Air Conditioning installs single-zone and multi-zone ductless systems across Port St. Lucie, Jupiter, Hobe Sound, Stuart, and the surrounding Treasure Coast communities.

Mini-splits are also one of the most energy-efficient ways to cool a space. They run on inverter compressors that ramp up and down with demand instead of cycling on and off, so they're quieter and use less power than a traditional system serving the same space. For Florida garage conversions and ADU buildouts (a growing trend on the Treasure Coast), they're often the only way to get permitting and code compliance without a major duct overhaul.

What we handle: Single-zone and multi-zone ductless mini-split installation, brand selection (Mitsubishi, Daikin, Fujitsu, LG, and others), wall-mount and ceiling-cassette indoor units, outdoor condenser placement and mounting, line set installation, electrical tie-in, smart controls, mini-split repair on existing systems, and warranty coordination across Port St. Lucie, Jupiter, Hobe Sound, Jensen Beach, Palm City, Tequesta, Saint Lucie West, and Hutchison Island.

Common Questions You May Have

These are the most common questions homeowners and business owners ask our team.
What AC services do you offer?

First Aid Air Conditioning handles the full range of residential and commercial air conditioning across the Treasure Coast: AC repair, full system installation and replacement, central air, ductless mini-splits, heat pumps, smart thermostat upgrades, indoor air quality systems, duct work, and routine maintenance and tune-ups. We work on every major AC brand and model. When your system fails, we move fast and treat every call like an emergency, because in Florida heat it usually is.

Do you install and replace AC units, mini-splits, and heat pumps?

Yes. We install and replace central air conditioners, ductless mini-splits, and heat pumps for homes and businesses across Hobe Sound, Hutchison Island, Jensen Beach, Jupiter, Palm City, Port St. Lucie, Saint Lucie West, and Tequesta. We size the equipment to your home, handle the permitting, and back the work with a manufacturer warranty (typically 10 years on the unit) and a 1-year workmanship warranty on the labor. A standard install runs four to eight hours.

Do you offer free estimates?

Yes. We provide free written estimates on installation and replacement projects, including new AC systems, mini-splits, heat pumps, indoor air quality upgrades, and full-system retrofits. For diagnostic visits on existing equipment, a small service call fee may apply, which is credited toward the cost of any repair you authorize.

Do you offer emergency AC service?

Yes. We offer fast-response emergency AC service across the Treasure Coast for total AC failures, water leaks from the air handler, frozen evaporator coils, electrical issues that trip your breaker when the system kicks on, and storm-related damage. The name First Aid means we treat every call like an emergency, because in a Florida summer it usually is.

Do you serve Port St. Lucie, Jupiter, Stuart, and the rest of the Treasure Coast?
