As of July 2026, First Choice Plus Plumbing & Air provides ductless mini-split installation, repair, replacement, and maintenance for homeowners in Port St. Lucie and the Treasure Coast. Since 2007, our team has helped homeowners cool difficult rooms, garages, additions, guest suites, and spaces without existing ductwork. We provide clear recommendations and pricing before work begins, and we offer free estimates for new ductless mini-split systems.
A ductless mini-split system is a heating and cooling system with an outdoor unit connected to one or more indoor air handlers. Each indoor air handler cools its own room or zone, so homeowners can control temperatures in specific areas without adding traditional ductwork.
Ductless mini-splits are often a good option for a room addition, converted garage, home office, guest suite, enclosed patio, or any room that stays warmer than the rest of the home. Many ductless systems are heat pumps, meaning they can provide cooling during Florida’s hot weather and heating during cooler days. Homeowners can learn more about how ductless systems work through the U.S. Department of Energy’s ductless mini-split guide.
A ductless mini-split is usually a strong choice when one part of the home needs independent temperature control or when extending ductwork would be difficult. A single-zone mini-split can serve one room, while a multi-zone system can connect several indoor air handlers to one outdoor unit.
A ductless mini-split may be the right solution if you have a garage that gets too hot, an addition without ductwork, a bedroom with uneven temperatures, a mother-in-law suite, or a room your central AC system cannot keep comfortable. If your whole home already has properly sized ductwork and needs one central temperature setting, a traditional system may be the better fit. Our air conditioning installation team can explain both options before you decide.
Proper sizing and installation determine how well a ductless mini-split performs. First Choice Plus Plumbing & Air evaluates the room size, ceiling height, windows, insulation, sun exposure, electrical requirements, equipment location, and the number of comfort zones needed before recommending a system.
Ductless mini-split installation can include mounting the indoor air handler, setting the outdoor unit, installing the refrigerant line set, connecting controls and electrical components, providing proper condensate drainage, and testing system operation. After installation, we confirm that the system is cooling correctly and explain how to operate and maintain it.
First Choice Plus Plumbing & Air performs Florida AC work under Certified Air-Conditioning Contractor License CAC1822029. You can review our license and insurance information before scheduling service.
A ductless mini-split that blows warm air, leaks water, freezes, makes unusual noises, displays an error code, or will not turn on needs a professional diagnosis. Mini-split problems can involve dirty filters, clogged drain lines, electrical components, communication wiring, blower motors, sensors, refrigerant-related concerns, or outdoor-unit failures.
First Choice Plus Plumbing & Air diagnoses the cause of the problem before recommending a repair. A low refrigerant level is not routine maintenance; it can indicate a leak that needs to be located and repaired correctly. For refrigerant-related concerns, see our AC refrigerant leak repair service.
If your mini-split has stopped cooling during extreme heat, has a burning smell, repeatedly trips a breaker, or leaks water near electrical components, turn the system off and request emergency AC repair in Port St. Lucie. Same-day and after-hours appointments are based on scheduling availability.
Mini-split repair may make sense when the system has a specific, repairable issue and is otherwise in good condition. A drain-line blockage, electrical component problem, sensor issue, or minor refrigerant-related repair may be less expensive than replacing the equipment.
Mini-split replacement may be the better long-term choice when the system has repeated major repairs, significant performance problems, an expensive component failure, or no longer provides enough comfort for the space. First Choice Plus Plumbing & Air will explain the condition of the existing system and provide repair and replacement options before work begins.
Ductless mini-split maintenance helps keep airflow, drainage, and cooling performance in check during Florida’s long cooling season. Homeowners should keep washable filters clean according to the manufacturer’s instructions and schedule professional service when the system has not been maintained, has reduced airflow, smells musty, leaks water, or is not keeping the room comfortable.
Professional mini-split maintenance can include checking cooling performance, indoor and outdoor components, airflow, filters, coils, electrical connections, condensate drainage, and visible system concerns. For ongoing AC maintenance, visit our AC tune-up and maintenance page.
Yes. A ductless mini-split can be a good cooling solution for a garage, addition, guest suite, office, or other room without ductwork. First Choice Plus Plumbing & Air evaluates the room and recommends equipment sized for that specific space.
Yes. Turn the cooling system off if you see ice on the indoor coil, refrigerant line, or outdoor unit. Running a frozen AC can cause more damage. A frozen system may be caused by poor airflow, a dirty coil, a blower problem, or a refrigerant-related issue.
Some single-zone ductless mini-split installations can be completed in one day. Multi-zone installations or projects with added electrical work may take longer, and First Choice Plus Plumbing & Air will explain the expected schedule before installation starts.
A ductless mini-split may leak water because of a clogged condensate drain line, drainage issue, frozen coil, dirty filter, or another problem affecting normal operation. Turn the system off if water is near electrical equipment and schedule a repair diagnosis.
Water leaking from an AC system is often caused by a clogged condensate drain line, drain-pan issue, frozen coil, or condensate pump problem. Turn the system off if water is near electrical equipment and schedule AC repair to help prevent water damage.
A ductless mini-split may stop cooling because of dirty filters, a frozen coil, electrical trouble, a sensor issue, a refrigerant-related problem, or an outdoor-unit failure. A technician needs to inspect the system to identify the actual cause.
Yes. First Choice Plus Plumbing & Air provides ductless mini-split repair for common cooling, airflow, drainage, electrical, control, and refrigerant-related problems. We explain the repair options and pricing before starting work.
A ductless mini-split should receive professional maintenance at least once a year, especially in Florida where cooling systems run for long periods. Cleaning filters regularly and addressing water leaks, weak airflow, and unusual noises early can help prevent larger repairs.
The price of a new ductless mini-split system depends on the equipment capacity, number of zones, electrical requirements, installation conditions, and chosen features. First Choice Plus Plumbing & Air provides a free estimate for new mini-split installation after evaluating the space.

Ductless mini-split installation does not have one fixed price because the cost depends on the system capacity, number of indoor zones, equipment brand and efficiency level, electrical work, line-set distance, mounting requirements, and site conditions. A single-room mini-split and a multi-zone system for several rooms are different projects with different equipment and labor requirements.

A ductless mini-split is usually best for targeted comfort in one room or several separate zones. It is especially useful where there is no ductwork or where the existing central system does not cool one area well.
Central air conditioning may be the better choice for whole-home cooling when the home already has usable ductwork and the homeowner wants one system serving the full house.
