Air Conditioning Repair Certification (ETI) Practice Exam

Ignoring routine maintenance on an air conditioning system can lead to decreased performance and an increased risk of breakdowns. Regular maintenance, such as cleaning filters, checking coolant levels, and inspecting components, ensures that the system operates efficiently. When maintenance is neglected, dirt and debris can accumulate, which can hinder air flow and reduce the system's ability to cool effectively. This not only results in poor performance, but it can also cause additional strain on the system, leading to more frequent and severe mechanical failures.

Over time, the cost of repairs due to a lack of maintenance can far exceed the cost of conducting regular upkeep. In addition, as the system struggles to operate, it can consume more energy, leading to higher utility bills. Therefore, regular maintenance is crucial not only for sustaining performance but also for preventing costly breakdowns and prolonging the lifespan of the AC system.
