The service your company provided was great. The heating system is working fine, the service your company provided was great. A special thanks to your crew that installed the duct work and furnace. I would certainly recommend Marathon Services to everyone. Thanks again.

Marathon Service is a very reliable and efficient company. They have been to my residence several times to work on my HVAC units, and I have been pleased. Not only are the technicians professional, but the office staff is as well. I highly recommend this company to meet all of your HVAC needs.

Never a complaint in the 5 years I did business with Marathon Service. They replaced an old unit and the entire process was seamless. Their price was more than fair and the quality of work was priceless. Everyone I dealt with at Marathon was respectful and true professionals. I recommend them for any of your HVAC needs.

Marathon recently installed a residential heat pump for us. They provided model options and very competitive pricing. They beat two large local competitors by about 10%. They showed up on time and did a thorough job in messy weather conditions. Thanks guys.

Marathon has been great. We have used their service for several years. They are usually able to come as soon as you call if a problem develops. This has been very helpful on the hot summer days. They are very knowledgeable. Their prices are reasonable. I don't feel that I have been overcharged. They explain the billing process very thoroughly so there have been no surprises. I highly recommend this company if you are having heating/cooling issues.

I highly recommend Marathon. I used them for the past 10 years and they were always quick to respond to issues. Eventually they replaced my old HVAC, which was done professionally. Their team members were courteous and knowledgeable. Thank you, Marathon Team.
