I called on a Monday morning when my heat pump stopped working. Annabelle was super friendly on the phone and said she’d do what she could to have someone come by that day, but it may not be until the next day, which I was fine with. She said she would call me back later that morning. True to her word, she called me back an hour later and said the technician was on his way!

Could not be happier with our technician, Jay! Purchased their service contract and Jay came out for a spring service at our beach house and did a fabulous job. He was hard working, kind and courteous. I hope he is available when it's time for our fall service! Annabelle in the office was wonderful as well. Price is very reasonable unlike most companies that service OC! Very pleased with Marathon and highly recommend.
