The receptionist is courteous and friendly. She asked specific question to fully understand the situation before rendering help for us. Jacob from the company arrived on time. He explained in detail the work to be done. He finished the work in a timely matter and left the place clean, even giving us tips on how to take care of it the next time if similar situation arises. Even though it is a small issue but they treated no different than other bigger jobs. It is hard to find this type of service and efficiency nowadays. Highly recommended.

These people are amazing. Christian was my service man. They came out to service my A/C and did an expert job. They made suggestions, weren’t pushy. Just did a super job. Also, I should mention Christians follow-up which I appreciated too. Good people. Id use them again.

Chris replaced a shower valve and made sure there’s no leak. Very professional, nice and courteous individual. Very happy with the outcome of his job. I highly recommend Marathon Plumbing, Heating & Air for any kind of plumbing job.

John Bonilla did a fantastic job with my system maintenance. The drainage line had clogged up with gunk and was causing water drainage to back up which was tripping the Safe-T-Switch float valve and shutting off power to my unit. He knew exactly what to do and was able to clear the clog and flush out the drain line. My system is working great now!

Javier did an excellent job all around! He was available earlier than our appointment time and after calling to let us know that he was available earlier, he promptly showed up and serviced our heater quickly and efficiently. He let us know of preventative maintenance that we can do, but wasn't pushy with us. We can't recommend his work enough!
