The Advantages of Replacing Your Furnace and Air Conditioner Together

When it comes time to replace your furnace or air conditioner, you’re often faced with a tough decision: is it worth replacing the other unit at the same time?

Don’t see the dilemma? It arises out of three facts:

  • The two systems work together, so they perform optimally when they’re compatible (or, as we say in the industry, “matched”).
  • In the world of heating and cooling systems, innovation happens quickly, and the new better-performing and more efficient units often aren’t matched with the ones made years back.
  • Furnaces tend to have a longer lifespan than air conditioners, generally lasting between 20 and 30 years, whereas air conditioners usually last between 15 and 20 years. So when you have to replace the one machine, often the other has only a number of years left in it.

So, back to the question. If you’re replacing your air conditioner or furnace, is it worth switching out the other unit too? It usually depends on how old the other machine is. If it has no more than five or so years left in it, it’s probably worth replacing the two together. Keep reading to learn why.

Better system performance
As mentioned, a matched furnace and air conditioner complement one another. This is because they share the same air handler, or blower. If you replace only one unit, the components don’t “match” and the new unit won’t work to its full potential.

 Increased energy efficiency
There have been considerable technological improvements in recent years, making both furnaces and air conditioners more energy efficient. Take a look at the Annual Fuel Utilization Efficiency (AFUE) ratio of your furnace and the Seasonal Energy Efficiency Ratio, or SEER rating, of your air conditioner and see how they compare with the current models. Sometimes switching out an old furnace or air conditioner saves you money in the long run simply because of the lower energy costs it represents.

Additional cost savings
As furnaces and air conditioners begin to get on in years, they typically require periodic repairs. And those repair costs can start to add up. When you get a new machine, you can count on it to run smoothly for years (especially if it features the latest technology). In addition, there’s the question of the warranty. Very often, manufacturers don’t need to honour warranties on a new system if they’ve been matched with an older one.

And, finally, replacing both units at once gets you a discount on installation. If you were to replace one unit now and then replace the other a few years later, you would be paying two installation fees, whereas if you replace both at once, your heating and air conditioning company will very likely give you a discount.
