The average unit also only lasts 12 to 15 years, so once your system reaches 10 years old, it’s time to start thinking about replacement. Call on the experts at Pacific Coast Home Services, though, to have us inspect your unit before purchasing a new one. We can suggest repairs to help extend the life while you begin to save for the AC installation. You can also count on our expertise when it does come time to replace. You may have had a unit too big for the home or worse, too small. Our team finds the perfect fit and helps meet you and your home’s cooling needs.
