Chris called us out today to perform an AC tune up at MaryAnna’s house. The AC system is about 10 years old and functioning well. I have one recommendation for the AC system, and that is a hard start. The hard start will help take a load off of the capacitor when the system kicks on. Overall, extending the life of the components on the AC. Second, I recommend a surge protector at the furnace to prevent any sort of damage that way and keep the system from falling out of warranty.
