New Air Conditioner

Our old air conditioner was probably about thirty five years old. It still worked ok but apparently there are some new regulations concerning appliances. The newest versions require all new lines, I was told. Fortunately my plumber had a couple holdover units that would work without a lot of changes. Since we just got new windows and put new siding on the house, it was the right time to have the new air conditioner installed too. It is very nice looking besides working well. I think it is a larger one than I had before.
