We can all agree that replacing an air conditioner and a furnace at the same time could be expensive, but the only way to ensure that your air conditioner performs at its rated efficiency is by replacing your furnace at the same time. The problem is that the average lifespan of a central air conditioner is about 15-20 years while the average lifespan of a furnace is about 15-30 years. In general, furnaces last longer than air conditioners — sometimes over twice as long. The following will explain why replacing your air conditioner and furnace at the same time (in order to install a “matched” system”) is probably the best choice…
When Both Systems Are 10+ Years Old
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. However, maybe the two systems were installed at different times originally. A furnace tends to far outlive most air conditioning systems. Meaning if your furnace is less than 10 years old and your air conditioner is the HVAC item that needs replacing you may just want to replace the air conditioning unit. So the judgment will have to be by the age of the HVAC equipment.
When Upgrading to a High-Efficiency Cooling System
The largest potential benefit to placing both your air conditioner and your heating system at the same time is in order to get what is called a matched system. Your air-conditioning and your furnace although separate units do share the blower system of your furnace. So, if you are replacing your air conditioning unit with a new improved unit it may not be compatible with your old furnace. Bottom line if you are looking to upgrade to a higher efficiency cooling unit you need to be ready to update your furnace also.
You Are Retiring Soon
If you are planning to retire and both of your systems are reasonably old, replacing them both right now can ensure that the next handful for years will be completely free of the stress of a furnace breakdown or an air conditioner failure. If you are still not sure if it is advisable for you to replace your HVAC Units together contact a trained professional who will be glad to help you make the decision that will suit your needs best.
