Mario did a great job, arriving on schedule and servicing both the furnace and AC units. He took photos and highlighted a potential issue that needs attention down the line. He also offered a quote for replacing or repairing the worn-out part. I'll definitely be calling Marathon in the Spring to have Mario service my A/C unit again.

The technician was a great communicator, keeping me in the loop about his arrival and work schedule. He arrived on time and kept me updated on what he was doing and where. His expertise also came with helpful tips for maintaining optimal unit airflow. Overall, pleasant interactions throughout.

I hired this company to inspect my Furnace, AC, and ductwork to get an estimate for replacing everything. The technician, David G, arrived promptly and was extremely friendly and knowledgeable. He explained the issues with my current systems clearly, making me feel at ease. I was very satisfied with the service, which was worth every penny of the $99 inspection fee.

Dale gave our home a thorough check-up, identifying some problems with the plumbing and hot water heater. He's now sending over the details. His work impressed me thoroughly.

I recently had a great experience with this home services company. The technician was very friendly and knowledgeable, making the process straightforward. They arrived on time and completed the job efficiently. My air conditioning is now working properly, which was a pleasant surprise given it's October. I would definitely recommend this service if you need any plumbing or HVAC work done, and ask for a specific technician if possible.

I've been to several places before settling on Marathon, and I'm thrilled I did. The service was top-notch, thanks to David G., who provided excellent assistance, was transparent, and made everything function smoothly. His friendly demeanor put me at ease. Normally, I wouldn't share my experience, but I appreciate the extra time he invested in helping us out. David's professionalism is impressive.

Mark from Marathon sent over someone for a quote - the guy was friendly and knowledgeable about the products, which helped me make my decision. I ended up going with a Goodman combo unit. The installation happened on a Friday and they were done by Monday night. The installers, Edmond and Saul, seemed very professional. Then a couple of days later, Patrick came to ensure everything worked properly and address any questions. Overall, this team is top-notch - great service and employees.

Our experience with Marathon was excellent. After a follow-up appointment, we encountered an issue with our heating system a week later. However, instead of leaving us without assistance, the company rescheduled a second visit for one of their technicians, Mario Chacon. He conducted a thorough inspection and explained the root cause of the problem – poor ventilation – to us in detail. To our surprise, we weren't charged for this additional service.

We were thoroughly impressed with the professionalism, friendliness, punctuality, and knowledge displayed by Marathon's technicians. We're extremely satisfied with their services and would highly recommend them to others.

We had an easy process with Jasmine to book our appointment, and then Jon was top-notch. He took the time to explain everything clearly to my husband and got our heating system up and running just in time for the unusually hot weather. Given that our building's infrastructure likely all uses Marathon, I can confidently endorse them.

Great experience overall - Justin arrived right on schedule and presented himself professionally. The plumbing duo, Bud and Benji, were knowledgeable and efficient in their work, providing a solid service.

This technician was friendly and efficient, completing his job quickly and tidily. He took the time to listen to my questions about upcoming plumbing work and made notes for a follow-up estimate. His professionalism is notable, especially considering it's a holiday week. Overall, I'd recommend him to others and appreciate the service provided during this busy period.

We hired Marathon to design our system after moving into our new home, and they got it right from the start. The team leader, Kenneth, was impressive - professional, knowledgeable, and showed a good understanding of different systems. He quickly got started and delivered great results. We're very satisfied with the outcome, especially considering the excellent service provided by Kenneth.

Troy, the serviceman, got it spot on - friendly and knowledgeable, no rush to wrap things up. He took time to answer all our questions, which was great. The whole team at Marathon, from scheduling to field ops, did a fantastic job.

Mr Bonilla initially came to fix our thermostat but when we mentioned our gas stove was also out of commission, he pieced together the issue - an earthquake valve had tripped. This saved us at least $700-800. His attention to detail and willingness to listen were impressive. He genuinely helped us out. I'm grateful for his expertise, especially since it went beyond just a simple repair job. He's clearly a top-notch serviceman. I have no hesitation about using the company again. Honestly, he seems underpaid - whatever the reason, he deserves recognition! Thanks to whoever made a smart hire like him.

This technician showed up on time, assessed the issue thoroughly, and took my previous attempts into account. They successfully got the heater running by connecting a wire to a vacuum port to rule out clogs, but only charged for a diagnostic due to their assessment that it wasn't a clogged problem. Before turning the system back on, they checked for carbon monoxide levels. The technician made some logical observations and suggested improvements. Throughout the process, they remained courteous and expert in their work.
