Tips for Cleaning Your AC System

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

If you haven’t cleaned it recently, it could be clogged with dirt and yard waste. This buildup can decrease your unit’s efficiency and cause it to break down. Or require replacement sooner.

We advise 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 electric bills.

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

Some of the work we complete involves:

  • Viewing the blower, motor, drain line and coils
  • Checking 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 ready for heating season too.

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

How to Clean Your Outside AC Unit

Select a temperate day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is great. That way, you can check the unit once you’ve cleaned it.

You’ll only need a couple 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

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

Then use the vacuum to cautiously clean the metallic fins. These pieces are also referred to as condenser coils and transfer heat away from your system.

You need to be cautious with these delicate coils. Misshapen or crushed fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also buy a fin comb from an appliance parts website. A pro from Smyth Air Conditioning Inc should handle extensive damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard waste. 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 operating correctly, reach out to us a call at 561-533-6066 .

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the juice to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be replaced every few months, depending on the type you use.

Can’t remember when you last replaced yours? Take it out and hold it up to the light. If there’s no light visible, buy 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 scummy, you can clean it by draining thinned bleach through the tube to clean the line. Or you can get a new tube.

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