Is there something I need to do to switch from AC to heat? Something need to be cleaned? Filters removed?
I can understand the fear, it is like having someone in the family very sick and fearing the phone ringing. You have to think of the fire alarm as startling but it has to be to get every ones attention. It is a friend telling you there may be a fire or smoke and you have to leave. Schools have windows and students can get out that way if needs be. Students are never trapped in a school fire because of the Alarm and fire drills. Consider it as time off from school and you get some fresh air. Good Luck!
That would be a very heavy road bike, an entry level decent quality road bike would usually weigh about 10 kg, a professional level race bike would weigh under 7 kg
