With summer coming up, you might be in a position where you’re ready to replace your old air conditioning system and start fresh. We think this is a good idea, especially if your air conditioner is more than 15 years old or it is showing signs it can’t keep up with the heat the way it used to. And if you’re thinking about investing in a high-efficiency air conditioning system with features like a variable-speed fan and multi-stage compressor, we also think that’s a good idea.
But we want to caution you that simply purchasing a high-efficiency AC isn’t an automatic ticket to lower cooling bills. It might not even be a way to get sufficient cooling.
