Tips for Cleaning Your AC System in Kearney

With summer winding down in Kearney, now is a good time to get a head start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be full of dust and yard waste. This buildup can decrease your unit’s efficiency and cause it to break down. Or require replacement more quickly.

We recommend having your air conditioning system professionally tuned-up once a year. Why? Clean equipment can be more energy efficient, which could save you money on energy costs.

Routine AC maintenance also helps our technicians locate and take care of slight issues before they become expensive problems.

Some of the work we do involves:

  • Viewing the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Examining lines, refrigerant totals and connections

It’s not too late to have a tune-up done this fall—and we can get your furnace prepped for heating season too.

There’s also some maintenance you can do on your own between professional tune-ups. It only takes about an hour to clean your outdoor condenser unit, as well as several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a mild day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can test your equipment once you’ve cleaned it.

You’ll only need a few tools:

  • Wet-dry vacuum and hose with a soft brush attachment
  • Screwdriver
  • Butter knife
  • Damp rag
  • Small, round paintbrush
  • Replacement furnace filter (if necessary)

5 Steps to Clean the Outside Unit

1. Turn Off the Power

Stop the electricity to your air conditioner at the breaker box.

2. Clean the Outside

Remove waste from the system. This includes branches, bushes, weeds and grass.

Then run the vacuum to slowly clean the metallic fins. These pieces are also known as condenser coils and transfer heat away from your unit.

You need to be cautious with these fine coils. Misshapen or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also use a fin comb from an appliance parts store. A pro from Thurston Heating & Air Conditioning should handle severe damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard litter. Then clean the inside of the unit with a wet rag.

The only coil cleaner you should use is water. Use slight pressure from a hose nozzle to wash the fins, spraying water from the inside out. Replace the fan once you’re finished.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating correctly, reach out to us a call at 308-624-3485.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be changed every several months, depending on the model you use.

Not sure when you last replaced yours? Take it out and tilt it toward the light. If light isn’t visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then inspect your air conditioner’s drain line—it’s a flexible plastic tube. If it’s dirty, you can freshen it by pouring thinned bleach through the tube to flush the line. Or you can replace the tube.

Scrub the drain port using a small, round paintbrush. Connect the drain tube and turn the power back on.
