Tips for Cleaning Your AC System

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 full of dust and yard waste. This buildup can reduce your unit’s efficiency and cause it to break down. Or require replacement sooner.

We advise having your air conditioning system professionally tuned-up every year. Why? A clean system can be more energy efficient, which could save you money on energy expenses.

Regular AC maintenance also helps our technicians locate and take care of small issues before they turn into high-priced problems.

Some of the work we perform consists of:

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

It’s not too late 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 by yourself between professional tune-ups. You only need about an hour to get the grime off 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 wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your system 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 rubbish 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 unit.

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

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also buy a fin comb from an appliance parts website. A pro from The Frazier Company should fix severe damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard waste. Then mop the inside of the system with a wet sponge.

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 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 properly, give us a call at 402-896-5900.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the juice to your furnace at the breaker box.

2. Check Your Filter

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

Not sure when you last replaced yours? Remove it and tilt 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 examine 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 clean the line. Or you can get a new tube.

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