Tips for Cleaning Your AC System

With summer ending in Williamsport, now is a great time to get a head start on air conditioner maintenance.

If you haven’t cleaned it this year, it could be clogged with mud and yard waste. This buildup can limit your unit’s efficiency and cause it to malfunction. Or wear it down sooner.

We suggest having your air conditioning system professionally maintained every year. Why? A clean unit can be more energy efficient, which could save you money on electric expenses.

Routine AC maintenance also helps our technicians spot and address minor issues before they turn into expensive problems.

Some of the work we perform includes:

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

There’s still time to have a tune-up done this fall—and we can get your furnace ready for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. You just need about an hour to get the grime off your outdoor condenser unit, as well as several components 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 great. That way, you can test your system once you’ve cleaned it.

You’ll only need a handful 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

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

2. Clean the Outside

Empty debris from the equipment. 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 considerate of these fine coils. Bent or crinkled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also buy a fin comb from an appliance parts website. A pro from Lycoming Heating Company should handle severe damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to clean the fins, directing water from the inside out. Reinstall the fan once you’re done.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not working correctly, give us a call at 570-244-2510.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

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

Can’t remember when you last replaced yours? Take it out and tilt it toward the light. If light isn’t visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

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

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