Tips for Cleaning Your AC System

September 20, 2019

With summer ending in Omaha, now is an ideal time to get a kick start on air conditioner maintenance.

If you haven’t washed it this year, it could be blocked with dust and yard waste. This accumulation can reduce your unit’s efficiency and cause it to break down. Or make it wear out sooner.

We suggest having your air conditioning system professionally maintained annually. Why? Clean equipment can be more energy efficient, which could save you money on energy expenses.

Regular AC maintenance also helps our technicians discover and address slight issues before they develop into costly problems.

Some of the work we complete consists of:

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

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

There’s also some upkeep you can do on your own between professional tune-ups. You just need about an hour to wash your outdoor condenser unit, as well as a couple of components on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a handful of things:

  • 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

Switch off the power to your air conditioner at the breaker box.

2. Clean the Outside

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

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

You need to be cautious with these fragile coils. Misshapen or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also buy a fin comb from an appliance parts retailer. A pro from The Frazier Company should fix extensive damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard rubbish. Then mop the inside of the equipment with a wet rag.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to clean the fins, showering 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 properly, give us a call at 402-628-0206.

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 few months, depending on the type you use.

Not sure when you last replaced yours? Remove it and angle it toward the light. If you can’t see light through it, buy a new one.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then take a look at your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can sanitize it by pouring thinned bleach through the tube to sanitize the line. Or you can get a new tube.

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