Have you read the manual that accompanies your HVAC unit or air conditioner model? Probably not. Therefore, most of your interaction with your air conditioner begins and ends with thermostat operation. If that's all you rely on, you'll be surprised if the unit fails to cool your living spaces. In fact, all along your own mistakes--like the ones below--may have something to do with it.
The filter seems to be a minor component if you don't know very much about how your unit functions. The unit's filter obviously filters particles out to protect the unit and indoor air quality. However, because it's integral to air flow when clogged, it's possible that the coils become too cold because warm air isn't flowing well throughout the unit.
Check the filter by consulting the unit manual; you'll discover its location and how to replace the piece if needed.
Failing to do Ground Maintenance
If the grasses or plants are long or if the leaves are allowed to remain unkempt, you'll be taxing the filter and fan blades by permitting all kinds of debris to interfere with the air conditioner. For best functioning, keep grass low and leaves away.
Not Cleaning Coils
You may have no idea that coils need to be cleaned, much less how to clean them. Unclean coils cannot operate effectively, in some cases freezing. That's why you should check the particular unit manual for information on location and cleaning tips. Most coils can be accessed by shutting down power, removing the cover of the unit and brushing grime and dust from any coils with a dry brush.
So many people think of sounds during operation as normal. Modern air conditioner and HVAC units are quiet compared with the models of the past; sounds usually mean something needs fixing. Buzzing, for example, could indicate loose parts in the motor or fan, leaks or a bad blower.
Not Replacing Batteries
Sometimes problems have very easy solutions. After wracking your brain to explain an air conditioning failure, all you need are charged thermostat batteries. If you don't have a schedule for ensuring batteries are current, you may deal with a problem for a long time before realizing it's a battery issue.
Mistakes and mistaken thinking can be fixed with good information if you're willing to change how you protect the appliance. Ask air conditioning or HVAC contractors for essential data about the appliance.
