Came to residence for prepaid MSC tune-up on a '19 Goodman furnace located in the basement. Equipment functional upon arrival. Upon inspection, I found the 16x25x1 filter is starting to get dirty and recommend replacing it soon. Typically they should be changed about once a month. All other electrical, mechanical, and gas components are operating properly and within manufacturer specifications at this time. See health report card for any specific information. Equipment functional upon departure. Thanks for your business and have a great day!
