FAQs About Ductless Mini Split Installation
Most single-zone installations are completed in one day. Multi-zone systems with multiple indoor heads typically take one to two days depending on how many zones are involved and where the indoor units need to be placed. We'll give you a clear timeline before we start.
Single-zone systems generally start in the $3,000–$5,000 range installed, depending on the brand, BTU capacity, and line set length. Multi-zone systems can range from $6,000 to $12,000 or more depending on the number of zones. We offer financing options to make it manageable — ask about KwikComfort and Mitsubishi financing.
Yes. Florida requires permits for mini split installations, and our team handles the permitting process for you. Every installation we complete is code-compliant and inspected.
Sizing depends on your square footage, ceiling height, insulation, sun exposure, and how you use the space. We use load calculations — not guesswork — to recommend the right system. An oversized unit won't dehumidify properly; an undersized one won't keep up in Florida's summer heat.
Absolutely. Many homeowners add a mini split to a specific room — like a sunroom, garage, or addition — while keeping central AC for the rest of the house. It's one of the most cost-effective ways to solve comfort problems without overhauling your entire system.
We install Mitsubishi, LG, Daikin, Gree, and Carrier. Our technicians are trained on each platform and can recommend the best fit for your situation and budget.
Why Proper Installation Makes All the Difference
A ductless mini split is only as good as its installation. The most common reasons mini-splits underperform or fail early aren't the equipment itself — they're improper sizing, an incorrect refrigerant charge, and poor indoor head placement.
At GoodWind, we do this right from the start.
What Our Installation Process Includes
Load Calculation & System Sizing
Before we recommend any system, we calculate your actual cooling and heating load based on room size, ceiling height, sun exposure, insulation, and Florida's climate. This ensures your unit runs efficiently — not constantly short-cycling or struggling to keep up.
Strategic Indoor Head Placement
Where the indoor air handler goes directly affects how evenly your room cools. We evaluate airflow patterns, furniture layout, and architectural features to find the ideal mounting location for even, quiet distribution.
Clean, Low-Profile Line Set Routing
We route refrigerant lines and electrical connections as neatly as possible — minimizing visible piping on the exterior and protecting the line set with proper insulation and UV-resistant covering made for Florida's sun exposure.
Correct Refrigerant Charging
Refrigerant charge is one of the most critical — and most often botched — parts of mini split installation. Too much or too little refrigerant kills efficiency and strains the compressor. Our technicians charge every system to the manufacturer's specification using digital gauges.
Safe Electrical Connections & Surge Protection
Florida's afternoon thunderstorms are hard on HVAC electronics. We ensure all electrical connections are properly made and can recommend surge protection to safeguard your investment.
System Startup & Testing
Before we leave, we run a full system test — verifying cooling and heating modes, checking remote control operation, confirming proper drainage, and walking you through how to use your new system.
Single-Zone vs. Multi-Zone: Which Is Right for You?
Single-Zone Installation
One outdoor unit connected to one indoor air handler. Ideal for:
- Sunrooms and Florida rooms
- Garage conversions
- Additions and bonus rooms
- Mother-in-law suites
- Short-term rentals needing independent comfort control
- Older homes where extending ductwork isn't practical
Multi-Zone Installation
One outdoor unit connected to two to five indoor heads, each in a different room or area. Ideal for:
- Whole-home comfort without new ductwork
- Older homes with existing duct problems
- Families with different temperature preferences by room
- Replacing a failing central AC system
- New construction without ductwork planned
Multi-zone systems give every family member control over their own space — without the energy waste of conditioning rooms that aren't being used.
