Welcome to my blog which covers a wide range of HVAC topics. I'm Josh and I live in Perth, Australia. I never really used to think about the HVAC system in my home. I believed that when it was hot the HVAC system would cool me down and when it was cold it would warm my house up. However, all that changed one day when the HVAC system went crazy. It began to blow hot air into my house on the warmest day of the year. The contractor I called out said that one of the sensors had broken. He explained how I could better maintain my HVAC system so I decided to start this blog.
