As long as my gas furnace gave heat, I paid actually little attention to it. I should have kept up with filter changes and scheduling professional maintenance in the fall. I neglected the gas furnace until it suddenly quit in the middle of the night. Since it was the end of January and the outdoor temperature was down to various degrees, I had no alternative however to call for emergency repair. I was not only anxious about my family’s comfort however the opening of the water pipes cold. It cost me a small luck to get a licensed professional to come to the home at that time of night. When the professional took the system apart, he found a considerable accumulation of dust and other debris on the inner toilings. He said that this grime had restricted air flow through the system causing it to overheat. After a actually thorough inspection, he informed me that the heat exchanger was cracked. I assumed that he could simply replace the heat exchanger, clean the gas furnace and get the system toiling again. I l acquired that the cost of a new heat exchanger was more than the gas furnace was worth. Because I hadn’t kept up with seasonal upkeep by a professional, the manufacturer’s warranty was no longer valid. I ended up paying for a brand new gas furnace to be installed. After that horrible experience, I right away signed up for a maintenance plan. I am now diligent about air filter changes and annual upkeep. I am determined to take actually enjoyable care of the gas furnace and make sure it lasts for as long as possible.
