Tips for Cleaning Your AC System

With summer ending in Ronkonkoma, 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 dirt and yard waste. This accumulation can reduce your unit’s efficiency and cause it to break down. Or wear it down faster.

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

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

Some of the work we perform consists of:

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

It’s not too late to have maintenance done this fall—and we can get your furnace prepared for heating season too.

There’s also some upkeep you can do by yourself between professional tune-ups. You just need about an hour to get the grime off 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 temperate day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can test your system once you’ve cleaned it.

You’ll only need a few 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

Cut 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 run the vacuum to slowly clean the metallic fins. These pieces are also referred to as condenser coils and divert heat away from your system.

You need to be careful with these fragile coils. Misshapen or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also get a fin comb from an appliance parts retailer. A pro from Cool Power LLC should take care of large amounts of damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard waste. Then clean the inside of the unit with a wet rag.

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Put the fan back in once you’re finished.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating correctly, contact us a call at 631-246-4029.

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 should be replaced every several months, depending on the model you use.

Can’t remember when you last put in a new one? Take it out and angle it toward the light. If there’s no light 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 scummy, you can sanitize it by flowing diluted bleach through the tube to flush the line. Or you can get a new tube.

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