Welcome to my blog! My name is Harold. Every Australian knows how important HVAC is in the summer months, but it is easy to forget that sometimes you need your HVAC system to provide heat in the winter months. A couple of years ago, I learnt a very important lesson. As the colder temperatures arrived, I switched on my HVAC system and expected to be basking in a tropical heat. Unfortunately, I hadn't used it since the height of summer, so I didn't realise that it had failed. I called an HVAC technician out to my house and they inspected the system. It turns out that the coils were covered in debris and this was causing the system to malfunction. Having repaired and maintained my HVAC system for the past 12 months, I decided to start a blog to encourage others to do the same.
