I don’t know why people tend to think that they don’t need to do anything, and yet everything is going to be just fine. As an HVAC technician for a local HVAC contractor, I have seen a lot and it always amazes me. What makes someone think that something as technical as a HVAC system can just be ignored and expected to continue running properly. It is a machine, and I remember my dad saying that it is if it will break, but when it is going to break. That is the reason why we have a maintenance and repair plan. It is the reason for the recommendation for the inspections and maintenance to be done about twice a year. It is the reason for the air filter changes, and the cleaning. The HVAC system is a machine that needs to be maintained if you want it to last for any length of time, and do its job safely and efficiently. Now it is starting to get close to when the furnace is going to need to be running. I can’t tell you how many emergency calls I will get because they have not had their HVAC equipment properly maintained. I will get phone calls in the middle of night, because they are shivering in their beds. Well, I have to get out of my warm bed to get their neglected HVAC equipment running to warm them up. Then, they have the audacity to be indignant because I hand them this large bill, when all I had to do was clean out the filth they neglected to have cleaned out two or three years running.
