What Our Satisfied Clients Have to Say

Rheem HVAC equipment maintenance and installations
Troy came and inspected the HVAC and Hot Water systems on a house we recently purchased and provided a proposal to replace the systems at various price points. We agreed to a date for the replacement. Troy and his team arrived as promised at 8:00AM and worked diligently all day until all tasks were completed and thoroughly tested. After cleanup the only way you would know they were here was the house was warm and the water was hot. Troy and his team communicate well, work efficiently, are a pleasure to have in your home. Marathon is a great company. I strongly recommend that you use their services.

Josh came out and was honest, professional, and on time. He was able to fix my heater and let me know what the issue was. He made sure to explain everything he did and what the issue was. His 12 years of experience showed and we will definitely be using Marathon again for all our needs.

Troy and his team are fantastic! Called, and in record time Josh found and repaired my heat issue. Very few companies give such great customer service! Call Marathon for all your HVAC issues, you will not be disappointed.
