Furnace issues caused me to call the HVAC company

What was that sound? I heard something loud happen and it woke up me in my deep sleep. Must have been nothing so I fell back to sleep. An hour went by and I woke up again and my room felt cold. I went to the thermostat dial to see what it was set at and it was at the temperature I always keep it at, a beautiful 80 degrees. The thing is I know this house isn’t at 80 degrees because it feels like it’s 65 in here. I understand to some people having your thermostat set to 80 degrees is awful but I love it. It’s just my comfort spot and I sleep well in it. I knew there was something wrong as my house to me felt like it was just way too cold. I’m not a fan of calling John and Mark, the local HVAC technicians, but there was something wrong with my HVAC system. I called John at 1 am and he answered like he always does. He is a nice HVAC tech who always looks out for the people. I heard his voice sounding all tired and I explained there is something wrong with my furnace. He asked if it was something he needed to check out now or if he could wait till morning, maybe like 7 am to stop by. I was a bit nervous and I said it’s fine, I’ll see him at 7 am but until then I’ll have to pull out my electric blanket to keep me at the comfortable temperature I need.
