Should you replace your AC and furnace at the same time, or should you just replace the unit that broke down?
This is a common problem for many homeowners, and deciding whether to replace one or both of your heating or air conditioning systems can be a real dilemma.
It may seem cost-effective to just replace the one that’s broken, however there may be advantages to replacing both at the same time. If your air conditioner has broken down but your furnace is still working fine, you may think it’s a good idea to get a few more years out of it.
The problem is that the older furnace is older technology, which can lead to problems. Old and new technology often don’t work well together, and therefore you’re not going to get the energy efficiency out of your system that you just paid for with your new AC system.
The furnace and AC systems produced today are more energy efficient than ever. How much more, you might ask? Systems built today can be 20% more efficient than systems built just 10 years ago! That’s big jump up in efficiency.
Not only can mixing old and new technology result in lower comfort levels and reduced energy efficiency, it also shortens the lifespan of both units. That said, there are exceptions to every rule, and sometimes your existing system may in fact be compatible with a new system. The best way to know for sure is to seek advice from a professional and get multiple options to meet your home cooling and heating needs.
