Are you thinking about purchasing a new air conditioner for your home? When doing so, know that size matters. It may seem like a larger system would be ideal because it could cool your home down quickly and provide you with more comfort. Yet, that is not the case. It is always best to work with an AC technician who can help you to choose the best size for your specific home based on the square footage and a few other factors. Why is a system that is larger than needed not a good thing?
