Should I Replace My Furnace and AC at the Same Time?

by VitalStorm Content on December 19, 2018

Replacing HVAC equipment is a major investment. Since furnace and AC replacement are each so expensive, it can be tempting to pay for them one at a time. You might find yourself wondering, “Should I replace my furnace and AC at the same time? What are the risks?”

Our team of highly-trained technicians at Blue Flame has replaced countless HVAC systems since 1994. Here are our recommendations on furnace and AC replacement.

Reasons You Should Replace Your Furnace and AC at the Same Time

The biggest reason to replace your furnace and AC at the same time is that otherwise these two components of your HVAC system will be operating with different levels of efficiency.

Advances in technology over the last decade have improved the overall efficiency of HVAC equipment. If you install a brand new AC unit that is drastically more energy efficient than your old one, it will be less compatible with your furnace. This means that you will sacrifice some of the efficiency and money savings that you paid for in the initial price of your new AC unit when you use your furnace.

You should definitely replace your furnace and your AC unit at the same time if:

  • Your furnace is more than 15 years old.
  • Your new AC unit has a SEER (Seasonal Energy Efficiency Rating) of 16 or higher.
  • The price of a new furnace is less when bought alongside a new AC unit.
  • A technician you trust recommends installing a matched system to avoid potential problems.

Reasons You Should Not Replace Your Furnace and AC at the Same Time

The biggest reason NOT to buy a new furnace when you buy a new AC unit is simply age. While AC units last 10-15 years, a well-maintained furnace can last 15-20. With meticulous care, some furnaces last up to 30 years.

If your furnace is getting old anyway, a matched system with a new AC unit and a new furnace is probably still the best way to go in terms of efficiency. However, if your furnace is less than 10 years old, it could still have over a decade of use left. Definitely do not replace your furnace with your AC unit if it is 10 years old or newer.
