Tips for Cleaning Your AC System

With summer winding down in Excelsior Springs, now is a great time to get ahead on air conditioner maintenance.

If you haven’t cleaned it recently, it could be full of mud and debris from your yard. This accumulation can limit your unit’s efficiency and cause it to malfunction. Or wear it down more quickly.

We advise having your air conditioning system professionally maintained every year. Why? Clean equipment can be more energy efficient, which could save you money on electric costs.

Consistent AC maintenance also helps our technicians locate and take care of small issues before they turn into expensive problems.

Some of the work we perform involves:

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

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

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

How to Clean Your Outside AC Unit

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

You’ll only need a couple 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 juice to your air conditioner at the breaker box.

2. Clean the Outside

Empty waste from the unit. This includes branches, bushes, weeds and grass.

Then run the vacuum to cautiously clean the metallic fins. These components are also referred to as condenser coils and divert heat away from your unit.

You need to be considerate of these fine coils. Misshapen or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also use a fin comb from an appliance parts retailer. A pro from Colvin's Heating and Cooling should handle severe damage.

4. Clean the Inside

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

The only coil cleaner you need is water. Use light pressure from a hose nozzle to rinse the fins, showering water from the inside out. Replace the fan once you’re finished.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not running properly, contact us a call at 816-379-3918.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the juice to your furnace at the breaker box.

2. Check Your Filter

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

Unsure when you last put in a new one? Remove it and angle 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 take a look at your air conditioner’s drain line—it’s a pliable plastic tube. If it’s dirty, you can freshen it by flowing diluted bleach through the tube to sanitize the line. Or you can replace the tube.

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