Do you have an area of your home that could benefit from climate control, but ductwork is either impossible? Then consider ductless system comfort from T.F. O’Brien Cooling & Heating.
We’ve been helping Long Islanders stay comfortable for decades, and we want to be your ductless contractor of choice.
More and more homeowners across Long Island are choosing ductless mini-split systems to heat and cool their homes, additions, and outbuildings. With Long Island’s hot, humid summers and chilly winters, these systems offer an energy-efficient solution for year-round comfort. One of the biggest advantages of going ductless is the potential for significant cost savings—especially in homes without existing ductwork. These systems are not only efficient but also durable, versatile, and relatively easy to install. If you’re considering a ductless mini-split for your home, now is a great time to explore whether this option is right for your comfort needs.
Give us a call to find out more about these innovative HVAC appliances that can cool and heat a room that was hard to live or work in during the extremes of weather we get here on Long Island.
