They installed a new HVAC system as part of our upgrade of our home’s ancient furnace heating system. They did a great job at a very competitive price. We have moved out of the LA area, but we would definitely recommend them to anyone in Southern CA who needs quality work at a fair price.

I’ve used Marathon HVAC Services, LLC. for years, to great satisfaction. Their technicians are knowledgeable, helpful, and timely. I recently had to replace my old heat pump, and they did an exceptional job. Ray Martinez, the owner, is responsive and helpful. We suggest Marathon in our condo building, and everyone has been happy.

Marathon HVAC Services, LLC. lead by Ray is the best! Reliable, straight forward – no BS – just a great team, competitive price, and great service – what more would anyone ask for! Marathon HVAC Services, LLC. has installed and serviced my Ductless A/C + Heating for my house and my backyard office. I will be calling again when I finish converting my garage to a live space as well.

Marathon HVAC Services, LLC. was highly recommended to me by my 170 unit condominium HOA President. My AC quit working and I needed a quick diagnosis and service. They responded to my call and were able to come out the next day. They quickly found the problem and had the parts in their truck and fixed it that same day. I felt like they were honest and fair in price. I would highly recommend Marathon HVAC Services, LLC. to anyone who needs help with their air conditioner system. Very nice and polite staff!!

Thanks to Ray and his crew of professionals, we no longer are suffering through the hot days! The Marathon HVAC Services, LLC. crew were very punctual, the installation was fast and efficient, and the equipment is working better than expected. There was even a follow-up visit (as promised) a few weeks after the installation to adjust the flow of air in some of the rooms. I have recommended them to friends and would gladly use their affordable service again.
