    Expert Mini-Split Installation From T. F. O’Brien

    Our expert technicians will conduct a thorough inspection of your Long Island home to ensure optimal system design. We then proceed with a precise installation, securely mounting the ductless AC units that go on the outside and inside of your home. We hook it up to your existing electrical system and charge it with refrigerant. Once everything is installed, we rigorously test the ductless heating system to verify its performance and functionality. Finally, we provide a comprehensive walkthrough with you, explaining how it operates and what maintenance is needed to keep it running smoothly year-round.

    No matter what your ductless AC and heating needs, the wide variety of systems available give you the efficiency, aesthetics, and comfort of a traditional system – much more efficiently than a window AC unit or space heater. We prioritize safety, efficiency, and cleanliness throughout the entire ductless air conditioning installation process. Our commitment to quality extends beyond installation with our comprehensive maintenance plans to keep your ductless system running smoothly for years to come.
