A common misconception about air conditioning systems we often encounter is that if an AC isn’t providing enough cooling for a home, the best solution is to upgrade to a bigger air conditioner. On the surface, this seems like a rational basic choice. Sometimes it is the best step: an air conditioning system that’s too small for the house it’s supposed to cool is the wrong AC for the house.
However, if you’ve had the same AC working in your home for several years and have only recently encountered the problem with poor cooling, going to a bigger air conditioner is a mistake. The air conditioner is the correct size to meet your cooling needs, but something else has gone wrong. You might need repairs for the system, or perhaps a new air conditioning installation in Los Angeles, CA—but not necessarily a bigger new air conditioner.
