David from Weltman came to do our annual A/C check-up. Everything has been working well (thank heaven!) but he crawled up into our attic and thoroughly examined our components there. He then checked our outside units, after which he showed me that dust and pollen particulates were being sucked into one of the units, but only in the back. He then carefully instructed me on how to clean those vents with our garden hose. I now feel confident our A/C will continue to function perfectly.
