Tips for Cleaning Your AC System

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

If you haven’t cleaned it lately, it could be blocked with mud and yard waste. This buildup can decrease your unit’s efficiency and cause it to malfunction. Or make it wear out faster.

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

Routine AC maintenance also helps our technicians spot and take care of slight issues before they turn into costly problems.

Some of the work we do consists of:

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

You can still have a tune-up done this fall—and we can get your furnace prepped for heating season too.

There’s also some upkeep you can do alone between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as a few 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 best. That way, you can check the unit once you’ve cleaned it.

You’ll only need a handful of tools:

  • 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

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

Then turn on the vacuum to cautiously clean the metallic fins. These components are also called as condenser coils and transfer heat away from your equipment.

You need to be cautious with these delicate coils. Bent or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also use a fin comb from an appliance parts store. A pro from Oak Grove Heating & Air Conditioning should take care of extensive damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use slight pressure from a hose nozzle to rinse the fins, directing water from the inside out. Put the fan back in 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 properly, reach out to us a call at 601-292-9763.

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 replaced every several months, depending on the type you use.

Can’t remember when you last checked yours? Remove it and hold it up to the light. If light isn’t visible, replace it.

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 freshen 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. Connect the drain tube and switch the power back on.
