Burrrrrr . . .

It's cold in my apartment!! I turned my HVAC unit on for the first time since I turned off the A/C this fall. It's really loud and rattling. I called my apartment management. They have the maintenance people coming out to look at it soon. Even the person from the office who came to listen to it said that it shouldn't sound like that. I hope they come soon because it's going to be cold again tonight. Good thing I have a lot of blankets!!
