Tips for Cleaning Your AC System

With summer coming to an end in Bloomfield, now is a great time to get a head start on air conditioner maintenance.

If you haven’t cleaned it recently, it could be blocked with dust and yard waste. This collection can limit your unit’s efficiency and cause it to malfunction. Or require replacement sooner.

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

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

Some of the work we perform consists of:

  • Viewing the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Testing lines, refrigerant totals and connections

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

There’s also some maintenance you can do by yourself between professional tune-ups. It only takes about an hour to wash your outdoor condenser unit, as well as a couple of pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a warm day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is great. That way, you can check your equipment 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

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

2. Clean the Outside

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

Then turn on the vacuum to gently clean the metallic fins. These pieces are also referred to as condenser coils and divert heat away from your system.

You need to be considerate of these delicate coils. Misshapen or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also use a fin comb from an appliance parts website. A pro from Stanford Heating & Cooling should fix extensive damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to clean the fins, showering water from the inside out. Reinstall the fan once you’re done.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not operating like it should, contact us a call at 812-825-8695.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be replaced every few months, depending on the kind you use.

Not sure when you last put in a new one? Remove it and hold it up to 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 scummy, you can sanitize it by flowing thinned bleach through the tube to flush the line. Or you can buy a new tube.

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