Hi there! My name is John and this is my new HVAC blog. I decided to start this blog last year when I realised that many people do not know how to properly look after their HVAC systems. I visited my brother in Sydney and I noticed that his home was very hot. I commented on this and offered to take a look at the HVAC system. I am not a professional HVAC contractor but I do know a thing or two about them. His system was full of dust and dirt so I helped him to clean it out.
