Needing to replace furnace

I appreciate all of our friends very much. I follow them all on their social medias closely to see what they are getting up to. It actually breaks our hearts when we see some sad things on there though. This guy I’m friends with came back to his house to notice that the one side of the home was boiling plus the other side was totally cold. He knew there was something very wrong with the Heating, Ventilation, plus A/C or with the thermostat. He called a local Heating, Ventilation, plus A/C corporation to come check what was going on with the Heating, Ventilation, plus A/C system he had. This guy waited plus waited in his uncomfortable house for hours until finally a repairman showed up. He told this guy that the problem was a stuck valve. The repair person fixed it however also told him that of course it could happen again at any time. The HVAC system itself was so old that the odds of it happening again were high. He realized that day that his heating system was a number of years old– way over the age of a proper heating system. That meant that he was stuck with a big decision to make. He needed advice as to whether or not he wanted to spend the money at the time to get a new heating system. However, the estimate they gave him happened to be incredibly high! He ultimately ended up bringing the price down plus being able to finance it so it worked out for the best– he got a brand new heating system put in plus all was right again. Apparently he even observed a difference in the heat in his home.
