My friend had a big problem with needing to replace her furnace

I love all of my friends very dearly. I follow them all on social media closely to see what they are up too. It absolutely breaks my heart when I see some sad things on there though. This one lady I know came home to a not so nice house. She came home and one side of the house was extremely hot and the other side totally cold. She knew there was something wrong with the HVAC system or with the thermostat. She called a local HVAC business to come check what was going on with the HVAC system she had. She waited and waited in her uncomfortable house for hours. Finally, a repairman showed up. He told her the problem was with a stuck valve. He had fixed it but also told her it could happen again at any time. The system was so old that the odds of it happening again are high. She had realized that day that her furnace was 47 years old. That is way over the age of a proper running furnace. She was stuck with a big decision to make. She needed advice on if she wanted to spend the money at the time to get a new furnace. However, the estimate they gave her was incredibly high! She ended up bringing the price down and being able to finance it so it worked best for her. She ended up having a brand new furnace put in and all was right again. She said she even noticed a difference in the heat in her home.
