Summer is around the corner. Have you thought of tuning up your air conditioner during summer? If you haven’t thought about it, this is the perfect time to do it.

We have created this checklist to make things a tad easier for you. 

Let’s dive in.

How Often Should I Tune Up an AC Unit?

You should tune up your air conditioner at least once a year. But that will depend on whether your air conditioner is still new or not. The older your air conditioner is, the more frequent you should tune it up. It is highly advisable to tune it up at least twice a year to prevent potential issues this summer. 

To keep your air conditioner in top condition, use the below tips: 

1. Inspect the Unit Panels

 Check if the unit panels are still in good condition. If they need to be replaced, replace them immediately. This should keep your air conditioner in good condition for the next 15 years.

2. Clear Away Debris

Next up, clear away any debris on your air conditioner. Start by removing the protective grilles from the condenser unit. 

Once you remove the side and top panels, you will readily clear any debris or dirt stuck on condenser coils.

3. Repair or Replace Pipe Insulation

 After a few months, your air conditioning system’s pipe insulation will likely wear out. So, you need to repair or replace the pipe insulation.

 Signs that your pipe insulation has degraded include the weak blowing power of your air conditioner.

4. Clean or Replace Air Filters

You can’t forget to clean or replace air filters. Dirty filters will reduce the amount of airflow and significantly reduce your air conditioner’s efficiency. 

5. Clean the Evaporator Coil

Residential air conditioner unit tune-up is not complete unless you clean the evaporator coil. Cleaning the air conditioner coil will remove any grime build-ups.

6. Check the Drainage Line

Your air conditioner is not clean if the drain is dirty. Even some of the most experienced technicians forget this. As a homeowner, it is your responsibility to check and clean the drain line.

7. Change the Air Filters

As air moves through your air conditioner, your air filters collect large and small dust particles. Hence, it is crucial that you change the air filters regularly. 

According to the American Society of Heating, Refrigerating, and Air Conditioning Engineers, your air conditioner will blow healthier and quality air when your air filters are in good condition.

8. Test The Unit

Lastly, it’s always essential to test the unit to ensure it works properly. If you feel that there is something wrong, you can always hire an HVAC company in Delaware like Miller Premier Services. They specialize in air conditioning, heating, and plumbing.
