Q. When should I replace my existing heating and/or air conditioning unit system? Check out our HVAC Replacement Guidelines.

All systems and units are different. Here are some rough lifespan guidelines to help you decide whether fixing or replacing is the right decision:

  • Average Lifetime of an Air Conditioner: 12-15 yrs.
  • Average Lifetime of a Furnace: 15-20 yrs.
  • Average Lifetime of a Boiler: 15-20 yrs.

Keep in mind that these are just guidelines. Some units last longer than that with regular maintenance and replacement of parts. But if a unit has been repaired repeatedly, or has been run excessively, it might make more sense to replace it even sooner. Paying for repairs to an old or inefficient system often simply prolongs the inevitable. An older system that breaks down once is likely to break down again…and again. That means more emergency service calls or, worse yet, the risk of damage to your home or to other components of your heating and cooling system.

There’s also an ongoing cost factor to consider. Restoring your old system will only bring it back to its current level of energy efficiency. After you’ve recovered from the repair bills and the frustration of system breakdowns, you still won’t save on your energy bills.

Some replacement systems can cost less than the cost of repeated repairs. And in many cases, installing a new heating and cooling system can actually pay for itself in energy savings within a very reasonable timeframe.

Also, when replacing a heater or air conditioner, it is usually best to replace both units at the same time. This way, you’ll save on installation costs and both systems will be sized and matched to maximize performance reliability and energy efficiency.
