Many of our posts revolve around providing regular maintenance to your HVAC so that you don’t need to replace it. However, every home’s HVAC system will need replacing every 20 years or so. This goes for your heating and air units, which are good to replace together.


There are some distinct advantages to replacing your A/C and furnace at the same time. Here are times to consider getting it done:

  • If your furnace is more than 15 years old
  • When your air conditioning is more than 10 years old and has a SEER rating higher than 16
  • If your current system is noisy
  • When a new, efficient HVAC unit will mean lower energy bills

Having a “matching” system (A/C and furnace installed together) has some advantages in terms of efficiency, compatibility, and even price if you’re bundling them together. But if your situation doesn’t match the situation above, it may make sense to only replace one or the other. 


The SEER rating measures an A/C’s efficiency. A high rating means your energy bill will be lower. However, a higher-rated unit will cost you more upfront. Here are a few things to consider when selecting a new A/C:

  • Price: As mentioned, paying more upfront will save you money on your bills.
  • Insulation: A well-insulated home is already saving you money, and can greatly boost your unit’s potential efficiency. It can also help you determine how much a new unit will save.
  • Regulations: All modern A/C units have a SEER rating of at least 13.

Most experts recommend a SEER rating of between 15 and 18, but you can consult The Darville Company for expert advice.
