Technician JAIME did a fantastic job, he thoroughly explained the HVAC maintenance process for my system and gave my entire system a tuneup it needed. I would recommend Marathon to others.

I’ve used Marathon multiple times over the past several years for both my AC and heater. They are prompt, trustworthy, friendly, and easy to schedule/communicate with. Jaime is an excellent technician, and Tomas, David, and Cesar did a great job installing our new HVAC system on our less-than-convenient rooftop. Thank you, Marathon!

Daniel did a great job! Very professional and friendly! I recommend him!

I have been dealing with Marathon for the past 3 years and am currently a VIP member. My service guy Leo Zepeda is very knowledgeable and professional and has always been very kind and efficient everytime he’s completed my servicing. It is wonderful to have such diligent employees and caring people working for you. Marathon recently merged with Marathon Hvac. Now they have expanded their service area in the Inland Empire. Hopefully, this will be a positive business expansion that brings more reliable service to the Inland Empire. Shout out to April who is also and outstanding office administrator. She’s on top of her job and is very pleasant when dealing with the public. Kudos to all the hard working employees!

Jaime did a excellent job. He replaced the thermostat. and supplied preventative maintenance

I had my seasonal maintenance today with Daniel Martin. He was very professional. He showed how much he loved working for this company, and how he loved his job. He showed me pictures of my system working when he was done. Great employee!
