Using the heater 48 hours straight each time

Using the heater 48 hours straight each time

It has been cold and super chilly frigid here in the section in which I live.

I live here in the north, and in the north it gets colder than ever.

It was so frigid the other afternoon and the next few afternoons after that it made my central heating and a/c’s heater run for 48 hours straight without even turning off! This was a first for me and I had never seen something like that happen in my full whole entire life before. I was delighted when it finally shut itself off after 2 afternoons straight. Otherwise, if I had to keep running just to keep the home boiling with indoor comfort, my biweekly energy bill would have been so high that I would have most likely not even been able to afford it and been in some trouble. This has been the most frigid winter season my good friend and I have ever had here in the north since I have been alive. And I am sure there are others who also had their central heating and a/c’s heater running for that long as well. I absolutely hope nothing like this happens again anytime in the near future. Because as I was saying, I do not want to have a super high energy bill that I can not pay! It is high enough as it is this time of year because of how frigid it is here in the northern part of the US of America, which is also the country in which I live. I do not need it becoming double or triple the cost of what it is.
