I'm new here and new to the HVAC Niche as well so i'm looking to learn about the niche and what are the problems that you usually face with the business

Hello everyone! I’ve got one room that is consistently warm. The air duct is getting cold air, but I have to keep the door open to the hallway to keep it from getting warm. There is no return in that room. Do y’all think installing a return will help? It’ll cost thousands. Thanks in advance!

Just wondering if anyone has opinions about putting in leak sealers to prevent leaks in the first place

I have my air conditioner that turns on, but I know it’s not blowing any cold air in my house. I put the digital thermometer and it only reads 80° when I have my unit set to cool. I made a video but I can’t tell what is possibly wrong.
