Should I Replace My Air Conditioner and Furnace at the Same Time?

Posted On: March 18, 2019

Any homeowner who has made the call to replace their old, outdated cooling or heating system can tell you that a new install isn’t the lightest load your finances have ever shouldered. Energy-efficient HVAC systems are more affordable than ever, but that doesn’t mean they’re cheap by any means. And so, if you’ve been considering HVAC replacement, you may have come across an important question: “Should I replace my air conditioner and furnace at the same time?”

As a long-time HVAC company serving Ogden, we’ve encountered this question a lot. And it’s a good question. But unfortunately, not one with an easy answer.

Scenarios in Which Replacing Your Cooling System and Heating System Works

The first bit of information we want to get across as plainly as possible is this: it is not always advantageous to replace your systems at the same time. There are situations where it is ideal, and also times where it’s only marginally beneficial, or not beneficial at all. Our team recommends replacing, essentially, when it will be more cost-efficient or effective to your comfort to do so.

When Both of Your Systems are 10 Years Old or Older

The general issue with replacing both systems at the same time is that a furnace tends to far outlive most standard air conditioning systems—meaning for most homeowners the two systems were installed at different times. If both of your systems are over a decade old, then replacing them both will typically provide enough benefits through energy-efficiency, performance, and reliability to make replacing them both together quite worthwhile.

Do note, however, that we do not recommend replacing a furnace younger than nine or so years unless you’re planning to change over to a heat pump.

When You Are Upgrading to a High-Efficiency Cooling System

Likely, the largest potential benefit to replacing both your air conditioner and your heating system at the same time is in order to get what is called a matched system. While your furnace and your central AC don’t share the majority of their components, they do in fact share the blower assembly system that is housed in your furnace.

This means that if you are getting a high-performance air conditioning system (any system that is rated 16 SEER or higher), then the performance of your new system will suffer because it is less than compatible with what your furnace has to offer in terms of the blower motor. Bottom line, if you’re looking to upgrade to a higher efficiency cooling unit you need to be ready to update your furnace, too.

When You Are Anticipating Retiring Soon

Retirement is a wonderful event that we all look forward to. It’s also not at all a time when, as your financial situation is stabilizing, you want to incur additional unplanned expenses. If you’re planning to retire and both of your systems are reasonably old, replacing them both right now can ensure that the next handful of years will be completely free of the stress of a furnace breakdown or an air conditioner failure.
