Tips for Cleaning Your AC System in Ballwin

With summer coming to an end in Ballwin, now is a good time to get a kick start on air conditioner maintenance.

If you haven’t washed it lately, it could be full of mud and debris from your yard. This collection can limit your unit’s efficiency and cause it to stop working. Or wear it down more quickly.

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

Consistent AC maintenance also helps our technicians discover and handle slight issues before they become high-priced problems.

Some of the work we complete includes:

  • Taking a look at 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 work you can do alone between professional tune-ups. It only takes about an hour to clean 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 mild day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your equipment once you’ve cleaned it.

You’ll only need a handful of 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

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

2. Clean the Outside

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

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

You need to be careful with these fragile coils. Misshapen or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to adjust misshapen fins. You can also get a fin comb from an appliance parts retailer. A pro from Holiday Heating & Air Conditioning should take care of severe damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard rubbish. Then mop the inside of the equipment with a wet cloth.

The only coil cleaner you have to have is water. Use slight 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

It’s safe to restore power and turn your air conditioner back on. If it’s not working like it should, contact us a call at 636-206-4250.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

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

2. Check Your Filter

Furnace filters need to be exchanged every couple of months, depending on the type you use.

Not sure when you last put in a new one? Pull it out and hold it up to 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 dirty, you can sanitize it by draining thinned bleach through the tube to flush the line. Or you can get a new tube.

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