“How many degrees can an air conditioner cool?” We get this questions a lot!
This summer of crazy hot temperatures is putting stress on you, and stress on your air conditioner. We’ve received a litany of phone calls from homeowners frustrated with their air conditioning system’s limited capacity to keep up with the heat outside. So, first thing, know that you’re not alone.
Second point, there’s likely nothing wrong with your system. While it seems abnormal for your house to be 77 degrees when it’s set for 71, the sustained high temperature is also abnormal. Your A/C is sized for what the temperature is likely to be in the summer, and as our climate averages indicate we’re traditionally in the mid 80’s. Your air conditioner is designed to cool a maximum of 20 degrees from the temperature outside. Pretty simple math. If it’s 100 outside, and you’re getting below 80 inside, your A/C is doing it’s job.
There’s little you can do to impact how hot it is outside your home, apart from planting shade trees and waiting a decade. What you can do is try to prevent that hot air from getting inside.
Like any mechanical system, your air conditioner needs to be maintained. The majority of emergency service calls we’ve received this summer could have been prevented with maintenance in the spring. If you’ve been lucky enough to stave off an emergency, you should consider having your system cleaned and checked for proper refrigerant levels. Keep the coils clean and the refrigerant levels correct won’t necessarily make it cooler in your home, but it will likely prevent your system from failing.
