From the Furnace room. Any thoughts? Seems like it makes this noise when I first start up the AC but subsides after about a 30-45 minutes.

Well the dandelions are outta control. This is a photo of about 1/4 of my backyard ( the most overrun). I put down a pre emergent granule in late March early April but dandelions were already starting to appear. I’ve sprayed Ortho Weedclear through a hose end sprayer on 2 different occasions in the last few weeks and while they’ve killed some dandelions, most of them have hardly been bothered. Last year it was pretty bad as well and I seem to remember putting down a weed and feed and that helping some. This fall I plan to aerate and overseed- but anything I can do in the mean time? Should I put down weed and feed or are their better 24D products than Ortho? I have a weed puller tool but it would take forever to get everything since I I have a big yard.Zone 5b
