I was kind of taken by surprise when my central heating and air conditioning system unit ended up blowing out.
I had just had my heat and a/c tune up from the local heating and air conditioning company.
They said that my central heating and cooling system was working very good. So when the HVAC system blew out I really did not understand. It turned out that a fuse had blown in the electric in the house. It actually had nothing to do with the central heating and cooling system. I found this out through general troubleshooting. I knew it had to be something simple and temporary like this. So I went outside to the breaker box, flipped the fuse, and the central heating and air conditioning system turned right back on and was working good as new as it should be. I am glad I did not jump the gun and call the local heating and air conditioning company for them to send out a certified heat and a/c specialist to come and repair my central heating and cooling system. Otherwise it would have been a waste of much money just to have them tell me a fuse blew and for them to come in and out and charge me several hundred bucks for that. Always troubleshoot issues with your central heating and air conditioning system before calling your local heat and a/c company. It could save you a lot of money in the end. I learned this very long ago!
