My A/C worked well for years and now suddenly messed up

I worry about trusting outside shops and services to take care of me.

I’d like to be the sort of person who was self-sufficient, so I didn’t have to worry about contacting others when something went wrong for me, then but, alas, I am not a handy individual. This is how I wind up in problematic situations with appliances all around the apartment – including the heating and air conditioning unit, most recently. The other day, my heating and cooling unit particularly ruined my day. I had really no clue that there was anything going wrong with my indoor air handling devices before the morning when the forced air gas furnace stopped, but for the past 4 years I have been using the same bullet proof indoor air temperature control system that came with my apartment. I have never once had an issue with temperature or air quality control before in the past. Then, last week I woke up and found that our indoor air temperature was freezing, especially compared to temperature control settings. There was no moderate air passing through our multitude of air vents and it felt as though the furnace had stopped operating hours earlier. I tried to mess with the oil furnace and temperature control for a few minutes before I eventually decided I needed to call the HVAC worker for expert help with the heating and air conditioning system. Unluckily, when I called to arrange our appointment, there was no answer on the other end. I called the shop a dozen times, however the line wasn’t being answered. I found out later that their front desk worker quit that morning, so there was no one answering phone calls through the heating and cooling repair shop to accept my HVAC inspection request. I really wish I didn’t count on them.
