We recently had Marathon install several mini-split units in our home, and we couldn’t be happier with the entire experience. The project took several days as expected for a job of this size, but their team was incredibly professional from start to finish. They were always punctual, showed up when scheduled, and worked late into the evening to make sure the job was fully completed each day. The technicians were kind, knowledgeable, and genuinely helpful — they took the time to explain everything, answer all our questions. What really stood out was their pricing.
Keith did an excellent job explaining the available options and working with me to get a system that met my needs. He did an excellent job installing it and his attention to detail and professionalism was outstanding.
Had some issues with our Minisplit system no longer producing heat right as it started to frost. Keith, our technician, came by on a weekend and got us fully operational in just under an hour and under two hundred dollars for a complex system, he was able to explain what happened, what he did to fix it, and preventative maintenance for us for future along with pictures and a full walk through. Keith is awesome, Marathon has a long term minisplit customer from us.
