Furnace & Air Conditioner: Should You Replace Them At The Same Time?

furnace and air conditioner

Some people believe that replacing an air conditioner and furnace at the same time will improve efficiency and result in savings, and it might, but the truth is that it really depends on your appliances.

Often it does pay to replace both your systems at once, but here’s what you need to know about your furnace and air conditioner to determine if one or both need replacing:

Know the Lifespan of Your Furnace and Air Conditioner

Properly maintained furnaces and air conditioners can last anywhere from 20 to 30 and 10 to 15 years respectively. We recommend you start thinking about replacing your air conditioner after 10 years and your furnace after 15.

Why Change Both?

When you replace your furnace it needs to be detached from the evaporator coil and other components. Your air conditioner requires the same thing, making it financially and practically convenient to replace your furnace and air conditioning at the same time.

What’s the SEER Rating?

The seasonal energy efficiency ratio (SEER) rating measures efficiency. If you are installing an air conditioner with a SEER rating of 16 or higher, then you should also replace your furnace. Your furnace and air conditioner work together, and your old furnace can sap efficiency away from your new air conditioning unit.

Up Front vs. Long Term Cost

When considering replacing either (or both) your furnace and air conditioner, compare the cost of the equipment with long term cost. With the right investment, your furnace or air conditioner can pay for itself in savings.

Know When to Replace

Your furnace and air conditioner’s expected lifespan is only an estimate. You might need to replace them sooner (but hopefully much later) than suggested. Be aware of the following signs you might need to replace your furnace or air conditioner:

  • Frequent repairs and rising energy bills mean that your furnace and/or air conditioner is not working efficiently anymore – replacement can be more cost effective.
  • Noisy equipment could indicate an internal problem or issues with duct work.
  • Humidity issues can also be caused by poorly functioning equipment or duct problems.

Contractors Charge More for Difficult Jobs

This fact is important to know if you live in an isolated area, or if your system is simply set up in an unconventional fashion. Replacing your furnace and air conditioner at the same time might be the best option if in a few years you’ll have to pay extra to get the other replaced. Changing both at the same time will minimize paying for installation, which you may not have factored into your budget.

Ultimately, whether it’s more cost effective to replace your furnace and air conditioner separately, or together depends entirely on your situation.
