There are some useful HVAC maintenance guides but people don't understand anything that is written there. So, they call us, HVAC technicians, because we are experts in this field and we know how to do our job. If someone here wants to check out what we actually do, you can click on this site. Some people say we have pretty easy work and we don't work as engineers or scientists so our work is like automatic work. But they are so wrong. I don't even argue with such people anymore. I just say them then why do you called me if you have an HVAC maintenance guide? And they just don't say anything.
