Central AC units are effective at cooling a home efficiently, providing that much-needed relief from that stuffy heat, come Spring/Summer time.
Although, your AC unit will only work well if the parts are kept clean and in a functional condition.
You will need to perform routine maintenance on your air conditioner so to keep the operating sufficiently.
Dirty filters will rob air flow and decrease the unit’s performance. Along with dirty filters, another energy waster is a dirty condenser coil.
If your AC unit is outside, it will likely collect the dirt the wind is blowing, thus the condenser coil becoming dirty which will not allow the sufficient airflow through the coil, therefore the refrigerant won’t be cooled as quickly, leading to a low efficiency.
Fan blades on the condenser fan or the squirrel cage fan inside that are damaged or unclean will eventually begin to vibrate and restrict the air flow.
Damaged or bent blades are what causes the vibration and will shorten the life of your motor. Build up of dirt and grime on the fan blades can also cause the vibration and restrict the air flow.
To see to these issues, your initial step would be to turn off the power to the AC unit and the outside condenser. You can then proceed to pick apart the condenser for a thorough clean.
To clean the coils, use a hose with a spray attachment and rinse.
When cleaning a blower fan, it is advised to call a professional to handle the job as they will be skilled in this area and have more expertise about the maintenance.
