    “I chose to install a duct-free system because I trust the Carrier® name, and also because of the rebate available. I did not have a previous system, so I was new to ductless air conditioning. The installer was very helpful. He walked me through the mechanics of the system and provided me with educational brochures. I would definitely recommend this system to other people, as it’s energy efficient. It’s also very quiet – sometimes we wouldn’t even realize it’s running if not for the cold air coming out!”
    ~ Joanne R., New York

    “Initially, I chose to install my duct-free split system because of the price. I had researched the product beforehand, but my installer helped me better understand how the system would work. It was less invasive to install than other systems, and I appreciate the quietness. I’d recommend it to others because of the quiet operation and advanced functions.”
