Should You Replace Your Gas Furnace After 15 Years?

As a gas furnace ages, it becomes less efficient and less reliable. The average lifespan of a gas furnace is around 15-20 years, and after this point, it is generally recommended to replace the unit. Here are a few reasons why it’s important to replace an old gas furnace:

  1. Energy Efficiency: Furnaces that are more than 15 years old are typically much less energy efficient than newer models. This means that they use more energy to produce the same amount of heat, leading to higher energy bills. A new, energy-efficient furnace can help to significantly reduce your energy costs.
  2. Reliability: An older furnace is more likely to break down and require repairs. As a furnace ages, it becomes more difficult and expensive to find replacement parts. With a new furnace, you can be sure that you’ll have heat when you need it, without worrying about unexpected repairs.
  3. Safety: An older furnace may not be as safe as a newer one. As a furnace ages, it can develop cracks or other issues that can cause carbon monoxide leaks. Carbon monoxide is a toxic gas that can cause serious health problems and even death. Replacing an older furnace with a newer, safer model can help to protect your family’s health.
  4. Environmental impact: Furnace technology have a big impact on your carbon footprint. An older furnace may not have the same pollution-reducing features as a new model. By replacing an older furnace with a newer, more efficient model, you can help to reduce your environmental impact.
  5. Comfort: An older furnace can leave your home feeling drafty and unevenly heated. Newer furnace models are designed to be more precise in maintaining your home’s comfort. With a new furnace, you can enjoy a more comfortable home that is heated evenly and consistently.

Overall, it’s a good idea to replace an older gas furnace after 15 years. Not only will you save money on energy bills and repairs, but you’ll also be able to enjoy a safer, more comfortable home that’s better for the environment. If your furnace is approaching 15 years of age, it’s a good idea to start thinking about a furnace replacement.

The technicians and installers at Rox heating and air are friendly, professional and helpful. Roger, Bert and Ty were professional, helpful and always willing to answer questions. They worked quickly and it was obvious that they had an abundance of experience installing systems.

I've been a customer of Rox air for a few years. Both for air and heating but also water heater. I am on there maintenance plan and they come out twice a year and do a thorough job checking out the systems. They spend a lot of time to make sure everything is working right for the next season. I would recommend them to anyone.
