That depends on your home! When you call Ray & Son Heating & Air Conditioning to purchase a new air conditioner, we’ll conduct an in-home measurement to match you to the right system. Finding the “Goldilocks” air conditioner is important: too big, and your AC will constantly be cycling on-and-off as it struggles to maintain a temperature without freezing your home. Too small, and your system will strain itself trying to keep up with the cooling demand. Both issues can lead to premature system failure. Our in-home audit will cover everything that might impact your AC load needs.
