Save Time & Money

Do you rely on an air conditioning unit to keep your home cool and comfortable? Without regular maintenance and care, your air conditioner won’t be as reliable as you’d like it to be. Fortunately, there are a some valuable air conditioning services you can perform yourself throughout the year to ensure a well-working air conditioner.

In this blog, we’ll give you tips that will save you money on energy bills, extend the lifespan of your unit, and help you avoid costly air conditioning repair services. Additionally, these tips will help ensure a higher quality of air in your home, free of dust, debris, and harmful bacteria.

Here are 6 DIY air conditioning maintenance tips:

1. Pay attention to the thermostat settings.

In order to improve the efficiency of your air conditioner, consider setting the temperature close to 78ºF during the summer. Adjust the setting to a higher temperature when you’re going to be out of the house for a long period of time to conserve energy. Setting it too low will require the unit to be constantly blowing cold air, which will not only use more energy, but it will shorten the lifespan of your unit.

Depending on the type of filters in your home, you may need to clean or replace them every month or every three months. If your air conditioner is constantly in use, you live in a dusty location, or you have furry pets, you may need to change the filters more frequently. Replacing your dirty or clogged filters with clean ones may reduce your energy usage by anywhere from 5-15%, while ensuring that your unit is working efficiently.

3. Clean the evaporator and condenser AC coils.

To do this, you’ll want to turn the unit off and use a wet/dry vacuum or a spray hose (not a pressure washer) to rinse off any dust or debris. Additionally, you may need to straighten out the coil fins. Located on the coils, these aluminum fins bend easily and can block airflow, reducing efficiency.

4. Change the blower filter at least twice a year.

You’ll want to replace this once before cooling season and again before heating season. Make sure you replace the filter with one that has the same airflow rating. A different type of filter can lead to reduced airflow, which may lead to frozen coils inside the unit.

5. Cover the top of the unit during the winter.

This will prevent debris from falling in and wearing the unit down or clogging its parts. Don’t cover the whole thing because it can get too humid inside and lead to bigger problems. Plus, a completely covered unit is an appealing breeding ground for pests and vermin.

6. Check the refrigerant level regularly.

The refrigerant is a liquid that plays a big role in the cooling process. Too much or too little refrigerant can increase energy costs and reduce the life of your AC unit.
