The Importance of Annual Air Conditioning Service


Wouldn’t it be lovely if everything was always in perfect condition, without requiring any upkeep from us? Our cars would run with no need for oil changes. Our clothes wouldn’t need to be laundered because they’d simply never get dirty. And we’d never find that anything—our hair tie, button, or charger cord—had come undone.

But here we are, in imperfect reality, where things come undone, get dirty, and need oil. Your air conditioner is one of those things. How can you make sure your AC unit stays in good shape? With annual maintenance. What happens if you don’t get maintenance? We’ll tell you all about it.

Why Maintenance Is Necessary

Over the course of a year’s AC use, a few key things happen inside your air conditioner. One is that, even if you are diligent about changing your air filter, dust will work its way into the unit. It builds up and coats things like fan blades and refrigerant coils. The second is that the lubricant on moving parts wears away. And the third thing is that, sometimes, tiny issues start to develop. Maybe it’s a screw slowly working its way loose. Maybe it’s the belt starting to slip from its moorings. Maybe it’s an electrical connection, and wires are coming undone. These things can happen just from the constant vibration. Because of these inevitable results of your air conditioner being in use, you need air conditioning service in Hanford, CA every year.

What Maintenance Includes

When your technician performs AC maintenance, all that dust and grime are cleaned from all the components of your air conditioner. This will help promote airflow and prevent grit from interfering with normal operation, and it will allow heat to be more easily absorbed from your air. Your technician will also lubricate moving parts like the motor and fans, reducing friction and cutting down on the effort—and energy—needed to keep them spinning. And to make sure none of those tiny issues we mentioned above turn into big problems, your technician will inspect all the components of your unit, checking for anything that is misaligned, undone, or leaking, and testing electrical connections and components.

What Happens Without Maintenance

Without professional attention, your air conditioner will continue to accumulate dust and grime. As it coats your evaporator coils, it acts as insulation, preventing the refrigerant from absorbing heat the way it should. Your air conditioner won’t be able to keep your house as cool anymore, and it will struggle harder and harder to do its job, straining the compressor. The dust will blanket the motor, which will already be experiencing too much heat from the friction of operating without proper lubrication. The limit switch may start shutting your unit down because of the too-high temperature, causing cycles to start up much too frequently, wasting energy and further stressing the compressor. As it gets hotter and hotter, wires may literally fuse together, burning out the motor completely. And in the meantime, any tiny issues will be developing into big problems, like a screw, fan blade, or belt flying free and damaging other components.
