They had either ignored cleaning the unit as they should have done; thus, dust accumulation causes blockages and sometimes irreparable damages that require the replacement of several components
My brother is a trained and certified HVAC technician. If there is a time that it is almost impossible to get him to enjoy spending time with his family or friends, this would be during winter. His phone is always buzzing constantly with clients requiring his services urgently. If it is not a failed thermostat, someone would be calling him to check on their furnace. Winter can be dreadful for him, not only because it is freezing but also because he gets too tired since he overworks. But why does this seem to be the case always? One may wonder. Sadly, most of his clients are ignorant of basic maintenance practices that ensure their furnaces and general HVAC units work correctly. It is common for my brother to receive distressed calls of a thermostat that doesn’t seem to work or a furnace that has broken down. While he loves his job and enjoys the cash that comes with such urgent heater repair jobs, he says that most such emergencies can be avoided. Generally, HVAC businesses are called in to fix an issue triggered by some form of negligence on the owner’s end. They had either ignored cleaning the unit as they should have done; thus, dust accumulation causes blockages and sometimes irreparable damages that require the replacement of several components. His advice to homeowners is to prioritize the regular maintenance of their heating and cooling systems. Such routine practice before summer or winter could help reduce unnecessary repair costs. HVAC repair services are not cheap, and most of the complex issues that arise cannot be DIY projects; thus, a professional must step in to resolve them.
