Tips for Cleaning Your AC System

With summer ending in Liberty, now is a good time to get ahead on air conditioner maintenance.

If you haven’t washed it lately, it could be full of dust and yard waste. This accumulation can reduce your unit’s efficiency and cause it to stop working. Or wear it down faster.

We recommend having your air conditioning system professionally maintained annually. Why? A clean system can be more energy efficient, which could save you money on utility bills.

Consistent AC maintenance also helps our technicians discover and take care of minor issues before they become expensive problems.

Some of the work we do involves:

  • Taking a look at the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Reviewing lines, refrigerant totals and connections

There’s still time to have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some maintenance you can do by yourself between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as a few parts 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 the unit once you’ve cleaned it.

You’ll only need a few items:

  • 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

Cut the power to your air conditioner at the breaker box.

2. Clean the Outside

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

Then use the vacuum to slowly clean the metallic fins. These parts are also called as condenser coils and transfer heat away from your equipment.

You need to be considerate of these fragile coils. Warped or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also use a fin comb from an appliance parts retailer. A pro from Air Unlimited Heating & Cooling should take care of extensive damage.

4. Clean the Inside

After taking out the fan, dig out leaves and other yard rubbish. Then wipe the inside of the unit with a wet rag.

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Replace the fan once you’re completed.

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 816-286-7258.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be replaced every couple of months, depending on the type you use.

Can’t remember when you last replaced yours? Remove it and tilt it toward the light. If you can’t see light through it, 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 pliable plastic tube. If it’s scummy, you can clean it by pouring thinned bleach through the tube to sanitize the line. Or you can replace the tube.

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