Is It a Good Idea To Replace Just a Furnace & Not an AC in Maryland?

Posted on: January 29, 2025

It’s certainly an option to replace your furnace on its own, but there are many reasons to replace your AC and heating system together.

The HVAC experts at Len The Plumber Heating & Air are here to explain the advantages of a total HVAC replacement for your Baltimore-area home.

Furnace vs. Air Conditioner Lifespan

While furnaces tend to have a longer lifespan than ACs, you should still consider replacing both if your furnace is around 15 years old. These two systems work together to heat and cool your home, so the best move is to equip your home with equipment that’s matched in terms of efficiency.

Modern air conditioners can last between 12 and 15 years, and newer units will be better optimized for peak energy efficiency than older ones. With a new AC working alongside a new furnace, you can moderate the temperature in your home as effectively as possible.

Benefits of Replacing Your Furnace & AC Together

A total HVAC replacement offers many advantages, including:

  • Improved efficiency: Newer systems have the latest technology that allows for higher efficiency ratings, which means your HVAC system will run more efficiently.
  • Optimized performance: Because your AC and furnace work together, it’s always best to have matching units. A matching system will operate at peak performance and minimize issues.
  • Maximized cost savings: A more efficient system means lower energy bills. Replacing both units together also reduces your repair and maintenance costs in the long run. Replacing them at the same time means you only have to pay for labor and additional fees once.
  • Comprehensive warranty coverage: Most HVAC equipment warranties expire after 10 years. A new furnace and AC will both have new warranties, ensuring you’re protected from any issues with your HVAC units.

Why Mismatched HVAC Systems Aren’t Recommended

You may think of your AC and your furnace as two entirely separate systems, but these units actually work in tandem to moderate the temperature in your home.

Typically, your AC and your furnace share an air handler, which is what circulates the heated or cooled air throughout your home. Units that are different ages or brands create the potential for costly issues with your system down the line.

If you pair a new furnace with an old AC, or vice versa, the older unit will experience advanced wear and tear trying to keep up with the newer one. You also won’t be able to take advantage of the performance and efficiency that a new system would provide.
