Tips for Cleaning Your AC System

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

If you haven’t cleaned it recently, it could be clogged with mud and yard waste. This accumulation can reduce your unit’s efficiency and cause it to stop working. Or make it wear out faster.

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

Regular AC maintenance also helps our technicians locate and address small issues before they become costly problems.

Some of the work we complete involves:

  • Inspecting the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Examining lines, refrigerant amounts 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 maintenance you can do on your own between professional tune-ups. It only takes about an hour to wash your outdoor condenser unit, as well as a few parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a handful 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

Stop the electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then use the vacuum to gently clean the metallic fins. These components are also referred to as condenser coils and transfer heat away from your equipment.

You need to be careful with these fine coils. Misshapen or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also use a fin comb from an appliance parts store. A pro from Climate Control Systems should take care of large amounts of damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard rubbish. Then mop the inside of the unit 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. 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 running properly, contact us a call at 828-283-0369.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

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

2. Check Your Filter

Furnace filters must be changed every several months, depending on the kind you use.

Unsure when you last replaced yours? Remove it and angle it toward the light. If light isn’t visible, get a new one.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then inspect your air conditioner’s drain line—it’s a supple plastic tube. If it’s dirty, you can clean it by draining water-down bleach through the tube to flush the line. Or you can buy a new tube.

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