You can make your AC unit more efficient and reduce regular maintenance costs with a few household tasks.

However, you should not attempt technical repairs and assessment; leave the work to a trained, licensed technician. While handling the maintenance task, always follow safety measures to ensure that the electrical supply is turned off. The following are easy household tips that you can perform for your AC unit.

1. Clean Air Filters

Air filters require replacement or regular cleaning. During high-use seasons such as winter and summer, do it every month and once during the spring and fall. You can locate the air filter in the blower section of the air handler or furnace, slot in the bottom, top, or side of your furnace, or behind the return air grille.

Once the air filter is full of dirt, dust, and allergen particles, it decreases the airflow. This increases the workload of the AC, which could result in a breakdown. Additionally, air flowing in the system might get dustier and dirtier, affecting the air quality in the house.

2. Perform a Check on the Unit’s Fan

It is essential to ensure the unit’s fan blades operate effectively. If they get damaged, your home might not cool as you wish. Remember to power off the electrical supply before you start your work. If the blades have visible cracks or chips, replace them with new ones.

3. Clean the Outside Unit

It is necessary to perform regular cleaning of the outside air conditioner unit. This is because, with time, grass and dirt might build, resulting in reduced airflow and poor system capacity. After disconnecting the power, clean the unit well to remove the debris.

Take care not to damage the fins on the coil; they are very delicate. Also, avoid a powder washer as it can damage the unit. The aluminum cooling fins on the AC compressor should be straight for effective cooling. Remember to trim shrubs around your AC to prevent them from interfering with the airflow.

4. Check the Thermostat

A thermostat ensures that your home keeps the right temperature. If you still use the old one, you should consider upgrading to a new smart and programmable thermostat.

With the smart thermostat, you can set when to turn on and off your AC. This will create a comfortable home for you and save on energy costs.

5. Ensure That Wiring and Components are in Place

The internal connections of the AC unit are essential to its operation. You should check them at least once a year to ensure they are in good condition. With the power supply turned off, remove the access panel and search for any sign of overheating.

Some of the signs include blackened or burnt wires and melted insulation. Also, check whether the electrical connections are tight. Only perform this task if you feel comfortable; if not, call for a trained technician for help.


An effectively working AC unit will save you money and keep you comfortable during high seasons. These routine check-ups will help keep your system running optimally and last for a long time. Apart from routine maintenance, contact a professional A/C repair service before winter and hot summer months to avoid late hustles.
