how to maintain your central air conditioner
Follow Us:

Most people take their central air conditioning for granted – until it breaks down in the middle of a heat wave. A central air conditioner is a great way to keep your home cool and comfortable during the hot summer. But like all mechanical systems, central air conditioners need regular maintenance to run correctly. Neglecting to maintain your AC unit can lead to expensive repairs or even replacement. Learning how to maintain your central air conditioner will help keep you cool and comfortable in the summer.

This blog post will give you some steps to maintain your central AC so it runs efficiently for many years.

Turn Off The Central AC

It’s crucial to shut off power to the air conditioner because of the risks associated with operating near electrical and moving elements of the appliance. Look for an outside shut-off box on the exterior compressor or condenser close to the unit. Additionally, shut off the electricity at the interior breaker box.

Get Rid of The Debris

After you’ve shut off power to the unit, remove any large debris like leaves or twigs around the outdoor compressor. It will ensure the airflow isn’t restricted when turning the AC on.

Next, spray in short bursts using a garden hose, and remove any smaller pieces of debris clinging to the unit. Be careful not to use too much pressure, as you don’t want to damage the AC unit.

If there is a lot of debris build-up, you may need to call a professional to clean the unit.

Remove and Clean the Filter

One of the most important things you can do to maintain your central AC unit is to change the filter regularly. Most filters should be changed every three months, but if you have pets or live in a dusty area, you may need to change the filter more often. A clogged filter restricts airflow and makes your AC unit work harder, leading to higher energy bills and shortened unit lifespan. 

Clean the Coils and Fins

The coils and fins on your AC unit can become dirty over time, which can restrict airflow and cause the unit to overwork itself. To clean the coils and fins, use a soft brush or vacuum attachment to remove dirt or dust from the coils and fins. You may need to use a commercial coil cleaning solution if the coils are dirty. Once you’ve cleaned the coils and fins, rinse them with clean water before turning the power back on.

Clear the Area Around Your Unit

Another simple way to keep your AC unit running is to make sure nothing is blocking the airflow around it. That means keeping the area around your unit clear of leaves, twigs, and other debris. It also means trimming any bushes or trees growing too close to the central AC unit. If the airflow is restricted, your AC unit won’t be able to do its job correctly.

Replace the Blower Filter

At least twice a year, immediately before the start of the heating season and just before the beginning of the cooling season, you need to replace your HVAC system filter. You may need to replace it frequently if you live in a region that gets a lot of dust. Always swap out the old filter with a fresh one with the exact airflow rating.

Turn The Power Back On

After finishing all the necessary maintenance tasks, you can turn the power back on to your AC unit. Start by turning on the power at the exterior shut-off box, and then head inside to turn on the breaker at the interior box. Give the unit a few minutes to start up, and then check to ensure it’s cooling correctly.

Schedule Annual Maintenance

Although you can do some basic maintenance tasks yourself, having a professional HVAC technician perform an annual checkup of your AC unit is essential. During this service call, the technician will inspect the unit’s moving parts and electrical components and make any necessary adjustments or repairs. They will also clean the coils and fins and check for signs of wear or damage. Annual maintenance is essential for keeping your AC unit running smoothly and efficiently. 

Conclusion

Proper maintenance is essential to keep your central air conditioner running efficiently and prevent costly repairs. Follow these simple tips to keep your AC in good shape all summer! Be sure to shut off the electricity at the interior breaker box before beginning any maintenance tasks. Then, remove debris around the unit and regularly clean the filter.

Additionally, you should clean the coils and fins on the unit periodically to ensure good airflow. Finally, don’t forget to schedule annual maintenance with a professional HVAC technician. These tips will help keep your AC unit running efficiently throughout the summer.
