Recently, there’s been an increase in our utility bill, then i was running our oil furnace in addition to cooling system at optimal temperatures, I was replacing the air filter correctly, in addition to our Heating, Ventilation plus A/C serviceman had just serviced our Heating, Ventilation plus A/C plan less than 6 months ago. I searched our apartment high in addition to low in addition to I couldn’t find any leaks where the air might be slipping out, but one night, I woke up feeling easily sizzling in addition to I couldn’t cool down, but while I was lying there in bed with no covers on, I realized that our oil furnace was continuously running. I waited for it to stop, but it didn’t! I never heard our oil furnace run this much during the daytime, but I didn’t understand why it was running so much at night. I went down the hall to find the control unit, which was directly across from our son’s room. I’ve always told him that he wasn’t allowed to touch the control equipment settings, so he knows better, then the control equipment settings weren’t changed, but it was significantly colder in that area in front of our son’s door. When I opened up his door, I noticed that his bedroom window was wide open. There was a strong breeze coming in, but our child was fast asleep. I quietly shut the window in addition to waited for our control equipment to notice that it wasn’t so chilly anymore. When I asked our child why his window was open the next day, he told me that he was easily sizzling during the night, but he knew he could not touch the control equipment settings.
