I made the dumbest mistake the other day. My gas gas furnace just would not turn on. I freaked out and study online about heating system issues. I study that if a heating system does not turn on, something major must be wrong. It means the heating system overheated and then quit. It also could mean the heating system has a sizable space that is malfunctioning. I immediately called our local Heating and A/C corporation to come in and make this costly heating system repair. I was prepared for almost a $400 bill for the gas furnace. I was all set to do what it took to have quality heating. A space of myself and others was anxious and anticipating having to buy another gas furnace system. The Heating and A/C professional did not even look at our gas furnace. He immediately went over to our temperature control and inspected it. He took the temperature control apart and then told myself and others our batteries were dead. I thought that surely could not be the issue. After replacing the batteries, the gas furnace turned on just fine. The heating system did not make any frightening sounds or threaten to turn off. It was just batteries in the temperature control that was the problem. The Heating and A/C guy charged myself and others $100 for that issue. He charged myself and others for the time he spent getting to our lake house and his labor. Changing batteries is considered labor? I was truly peeved after paying that bill. I am never going to make this mistake again. Not only was it a extravagant 1, even though I felt adore such an idiot in front of our Heating and A/C professional.
