Tips for Cleaning Your AC System

With summer winding down in Suffolk/Nassau County, now is a good time to get ahead on air conditioner maintenance.

If you haven’t taken care of it recently, it could be clogged with dust and debris from your yard. This accumulation can decrease your unit’s efficiency and cause it to malfunction. Or require replacement sooner.

We advise having your air conditioning system professionally maintained every year. Why? Clean equipment can be more energy efficient, which could save you money on electric expenses.

Regular AC maintenance also helps our technicians discover and handle slight issues before they become costly problems.

Some of the work we complete consists of:

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

There’s still time to have maintenance done this fall—and we can get your furnace prepped for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. You just need about an hour to clean your outdoor condenser unit, as well as a couple of components 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 test your system once you’ve cleaned it.

You’ll only need a couple 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

Cut the power to your air conditioner at the breaker box.

2. Clean the Outside

Take out waste from the equipment. This includes branches, bushes, weeds and grass.

Then run the vacuum to gently clean the metallic fins. These pieces are also called as condenser coils and move heat away from your unit.

You need to be considerate of these fragile coils. Misshapen or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to adjust warped fins. You can also buy a fin comb from an appliance parts website. A pro from Airmax Long Island Inc should take care of extensive damage.

4. Clean the Inside

After taking out the fan, pull out leaves and other yard waste. Then mop the inside of the system with a wet cloth.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to rinse the fins, directing water from the inside out. Replace the fan once you’re done.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not working correctly, give us a call at 631-737-5566.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be changed every couple of months, depending on the type you use.

Can’t remember when you last checked yours? Take it out and tilt 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 examine your air conditioner’s drain line—it’s a supple plastic tube. If it’s moldy, you can clean it by flowing thinned bleach through the tube to clean the line. Or you can get a new tube.

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