Hi! So I tried to use my AC a few days ago. I switched my thermostat to 'Cool', and after a little bit I heard it click on. Outside fan works. I changed my furnace filter 2 weeks ago. No cold air from vents. I went down to the furnace, and the metal that usually gets cold is not cold. I do not see ice anywhere. Could this be due to low refrigerant? Capacitor? Bad coils? Thanks!

Recently purchased a home that had been gut remodeled by the seller. After several months we have noticed a spot in the kitchen where the wood flooring has slightly changed texture and slats are pulling apart from one another a little. When I stand there I can feel that its a cold / warm spot (depending on the season). We do not have a duct anywhere in the kitchen. Closet duct is decently far away. Underneath the kitchen is a finished basement with a couple ducts in the ceiling, but they are not in a similar location. So my theory is that a duct should have been put in the kitchen floor or underneath the cabinet flashing. Does this sound reasonable? Given that the space underneath is finished, do I have any way to confirm this theory (without destroying anything)? The hot / cold spot is very close to cabinets, so my best guess is to drill down through the cabinet and see if I can explore that way, as such damage will be hidden from plain sight. Or should I just call a professional? I'm not sure though they'll have any better way to know than I would. And I do not have any direct way to contact the original contractor (so its all out of my pocket). Thanks!
