Professional Mini-Split Installation for Long Island Homes
Efficient, quiet, year-round comfort without the ductwork. Ductless mini-split systems provide precise temperature control, exceptional efficiency, and whisper-quiet performance.
Common Problems Mini-Splits Solve Instantly
Hot rooms that never cool down
If certain rooms in your home are always too hot, especially upstairs bedrooms or sun-facing rooms, a mini-split provides dedicated cooling exactly where you need it. Each zone can be controlled independently, eliminating hot spots permanently.
Cold rooms that never warm up
Older homes often have rooms that stay cold in winter, especially additions, finished basements, or rooms far from the main heating system. Mini-splits provide efficient heating to these problem areas, ensuring every room stays comfortable.
Humidity issues and poor air quality
Mini-splits include built-in filtration that removes dust, allergens, and pollutants. They also provide better humidity control than traditional systems, eliminating musty smells and improving indoor air quality throughout your home.
Uneven temperatures throughout the home
If your home has inconsistent temperatures from room to room, mini-splits solve this with zoned comfort control. Each room can have its own temperature setting, eliminating the need to compromise on comfort.
Noisy window AC units
Window AC units are loud, inefficient, and block windows. Mini-splits operate as low as 19dB—quieter than a whisper—and don't block windows or views. They provide superior comfort without the noise.
High energy bills from inefficient systems
Mini-splits have SEER2 ratings up to 28+, making them extremely energy efficient. They can reduce your utility bills significantly compared to older central systems or window units, paying for themselves through energy savings.
Limited ductwork space or no existing ducts
Many older Nassau County homes don't have ductwork, and adding it can be expensive and disruptive. Mini-splits require no ductwork, making them perfect for older homes, additions, and spaces where ductwork isn't feasible.
Efficient, Quiet, Year-Round Comfort Without the Ductwork
Ductless mini-split systems are one of the most energy-efficient, flexible, and modern ways to heat and cool your home. Whether you're upgrading an older system, adding comfort to a new room, or renovating your space, a professionally installed mini-split gives you precise temperature control, exceptional efficiency, and whisper-quiet performance. At Home+s Air & Heat, we specialize in ductless mini-split system installation for homes and businesses across Nassau County. We install single-zone and multi-zone systems, design custom layouts, handle electrical and refrigerant line work, and ensure everything is installed to manufacturer standards for maximum longevity and performance. Mini-splits provide comfort exactly where—and how—you want it, making them perfect for older Long Island homes without central HVAC, new additions, finished basements, sunrooms, garages, and any space where you need efficient, fast comfort.

Our Mini-Split Installation Process
Why Homeowners Choose Mini-Split Systems
Our Simple Process
From call to comfort in 9 easy steps
In-Home Assessment & System Design
We start by evaluating your home layout, insulation levels, room sizes, electrical capacity, sun exposure, windows and airflow patterns, and existing HVAC systems. Then we design a custom mini-split solution tailored to your home's specific needs and comfort goals.
Mini-Split Sizing & Load Calculation
Correct sizing is everything. Oversized systems short cycle and waste energy. Undersized systems run constantly and never reach temperature. We perform Manual J load calculation, room-by-room BTU analysis, and multi-zone distribution planning. You get a system that performs perfectly year-round.
Indoor Unit Placement
Proper placement affects airflow, efficiency, noise levels, and temperature consistency. We select optimal locations based on structural layout and comfort needs. Whether wall-mounted, ceiling cassette, or floor-mounted, we ensure each unit is positioned for maximum effectiveness.
Outdoor Unit Setup
We install the outdoor condenser with vibration pads, proper spacing, ground-mount or wall-mount brackets, weather protection, snow clearance, and airflow optimization. Everything is positioned for long-term reliability and performance.
Refrigerant Line Installation
We use high-quality insulated copper lines and secure them in a low-visibility, aesthetically clean line set cover. We follow all EPA standards and ensure proper insulation to prevent energy loss and maintain efficiency.
Electrical, Drain, and Termination Setup
Our installation includes dedicated electrical circuits, proper grounding, condensate drain installation, weather-proof disconnect box, line set insulation, and UV protection. Everything is 100% code-compliant and built to last.
Vacuum, Pressure Test & Refrigerant Charge
This is where most cheap installers cut corners. We don't. We pull a deep vacuum, pressure test with nitrogen, confirm refrigerant balance, check for leaks, and validate system performance. This ensures peak efficiency and long equipment life.
System Startup & Calibration
We test airflow, heating and cooling performance, thermostat accuracy, refrigerant pressures, temperature split, and noise levels. We verify everything is operating correctly and efficiently before we leave.
Cleanup, Training & Warranty Registration
After installation, we clean up everything, show you how to use the remote, demonstrate settings and efficiency modes, and register your system for full manufacturer warranty. You get a perfect installation and complete peace of mind.
