If I replace my outdoor unit, do I need to also replace my indoor unit?
If I replace my outdoor unit, do I need to also replace my indoor unit? In most cases, the answer is yes. There are a variety of reasons why you should replace both the outdoor and indoor unit simultaneously. For starters, air conditioner and heat pump outdoor units are manufactured to work with a matched indoor unit. When you mix and match units, it can result in reduced efficiency and performance.
Also, if you bought your indoor and outdoor units at the same time, your indoor unit will probably be approaching the end of its useful life at about the same time the outdoor unit. By not replacing the indoor unit too, all you’re doing is delaying the inevitable and likely paying higher energy bills at the same time.
By purchasing indoor and outdoor units simultaneously, you’ll get a warranty covering the whole system, meaning that you won’t have to cover the full cost of any needed repairs to your unit during the warranty period.
