Tips for Cleaning Your AC System

With summer winding down in Huntsville, now is a good time to get a head start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be blocked with dust and yard waste. This accumulation can decrease your unit’s efficiency and cause it to break down. Or make it wear out faster.

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 utility expenses.

Consistent AC maintenance also helps our technicians locate and handle minor issues before they develop into high-priced problems.

Some of the work we do includes:

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

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

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

How to Clean Your Outside AC Unit

Select a mild day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can check the unit 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 juice 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 use the vacuum to gently clean the metallic fins. These parts are also referred to as condenser coils and move heat away from your equipment.

You need to be considerate of these fine coils. Warped or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust warped fins. You can also use a fin comb from an appliance parts store. A pro from All Weather Heating & Air Conditioning Inc should handle extensive damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard rubbish. Then clean the inside of the system with a wet cloth.

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to wash 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 working properly, reach out to us a call at 256-801-4701.

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

Unsure when you last checked yours? Remove it and hold it up to the light. If light isn’t visible, get 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 flexible plastic tube. If it’s dirty, you can sanitize it by pouring diluted bleach through the tube to sanitize the line. Or you can get a new tube.

Wash the drain port using a small, round paintbrush. Reconnect the drain tube and restore power.
