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 ...

“Had a quote for repair from another vendor that was far higher, ridiculously high. Marathon was far less, and great work. When they didn’t quite fix the problem, returned promptly and identified what needed to be done & only charged for the part, not labor. Fast, and polite, they will be my only HVAC service from now on.”

“Marathon HVAC Services, LLC. was recommended by a contractor for a remodel. They replaced old ducting, relocated the furnace and coil, and installed new air vents. A big job and definitely not an easy one, but they were thorough. They are transparent and honest with what work needs to be done. Their quote was reasonable”

“Ray Martinez and his team are responsive to my concerns about issues with the HVAC equipment and are able to come out to my home to repair equipment, and/or service it in a timely manner. The prices for service and for equipment are fair and reasonable.”


Expert Furnace Installation: Identifying Signs for a Seamless Upgrade!

Is your home experiencing inconsistent heating, unusual noises, or a spike in energy bills? Recognizing the signs that indicate a need for a new heater or furnace is crucial for maintaining a comfortable and efficient living space. Here’s a comprehensive guide to help you identify when it might be time to consider upgrading your heating system with a new furnace installation.

Keep an eye out for these telltale signs and ensure your home stays warm, safe, and energy-efficient.

  • If your furnace or heater is over 15 years old, it may be less efficient and prone to frequent breakdowns, indicating the need for a new system
  • If you find yourself constantly calling for repairs, it may be more cost-effective in the long run to invest in a new, reliable furnace or heater.
  • Unusual noises such as banging, popping, or rattling during operation can be signs of mechanical issues, suggesting it might be time for a replacement.
  • If your thermostat struggles to maintain a consistent temperature or if there are significant temperature fluctuations, it could be a sign that your heating system is struggling
  • Advancements in heating technology may offer increased efficiency and control. If your system lacks modern features, upgrading could lead to improved comfort and savings.
  • A sudden and unexplained spike in your energy bills could signify reduced efficiency, signaling the potential need for a more energy-efficient heating system.
  • Uneven heating throughout your space or rooms that are difficult to keep warm may indicate an aging or malfunctioning heating system.

A yellow or flickering pilot light could be a sign of carbon monoxide production, a serious safety concern that requires immediate attention and potentially a new heating system.

  • If you notice rust or visible cracks on your furnace or heater, it may be a clear indication that the system is deteriorating and needs replacement.
  • Old or inefficient heating systems may not filter air effectively, leading to more dust and dryness in your home. Upgrading can improve indoor air quality.
