Tips for Cleaning Your AC System

September 20, 2019

With summer winding down in Neptune City, now is an ideal time to get ahead on air conditioner maintenance.

If you haven’t washed it this year, it could be clogged with dirt and yard waste. This buildup can decrease your unit’s efficiency and cause it to break down. Or wear it down sooner.

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 energy costs.

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

Some of the work we complete consists of:

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

There’s still time 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 on your own between professional tune-ups. You just need 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 warm day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run your system once you’ve cleaned it.

You’ll only need a few 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

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

2. Clean the Outside

Empty rubbish from the system. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to slowly clean the metallic fins. These components are also known as condenser coils and move heat away from your unit.

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

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also get a fin comb from an appliance parts retailer. A pro from Aggressive Mechanical should handle large amounts of damage.

4. Clean the Inside

After taking out the fan, dig out leaves and other yard rubbish. Then mop the inside of the equipment with a wet rag.

The only coil cleaner you need is water. Use gentle pressure from a hose nozzle to wash the fins, showering water from the inside out. Replace the fan once you’re completed.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not operating properly, give us a call at 732-806-5536.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the juice to your furnace at the breaker box.

2. Check Your Filter

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

Unsure when you last checked yours? Pull it out and tilt it toward the light. If you can’t see light through it, buy 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 scummy, you can freshen it by flowing diluted bleach through the tube to sanitize the line. Or you can buy a new tube.

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