In our 25+ years in the heating and cooling industry, we’ve learned that the average lifespan of central air is 20–25 years. An air conditioner may need to be replaced earlier if its capacity is not properly matched to the cooling load of your home. Remember, the older the unit, the less efficient it will be, and the more it will cost you in energy bills. As a reputable, trusted installer, we ensure you get a properly sized air conditioner for your home, providing you with a more efficient cooling solution.
