For the past four days my furnace has been making this odd clicking noise. It's been getting worse but tonight my heat wasn't able to keep up with the outside. The heat still somewhat works. It's 65° inside, thermostat is set to 70° and it's 15° outside.I need to be able to fix this myself. I'm a bit broke after car troubles and Christmas so I can't afford an HVAC technician right now. Please help.Here's a video via /r/DIY http://ift.tt/2lpIBBH
