Marran is your Long Island A/C expert

We offer installations and maintenance and repair everything from small ductless units to large, multi-zone central air conditioning systems. 

 Installation and Replacement

Marran has been designing and installing central air conditioning systems for decades. Our technicians go through our rigorous training program and work exclusively for us. They come to your home or office fully prepared, with all the equipment they need to get the job done as quickly and efficiently as possible. We never use subcontractors. 

Before we set up an installation date, we’ll schedule a free survey to size up your house, give you a quote, and ensure that the system we give you a quote for is perfect for your home.
