Tips for Cleaning Your AC System

September 20, 2019

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

If you haven’t washed it recently, it could be clogged with dirt and debris from your yard. This accumulation can reduce your unit’s efficiency and cause it to break down. Or wear it down sooner.

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

Regular AC maintenance also helps our technicians discover and address slight issues before they develop into expensive problems.

Some of the work we complete consists of:

  • Inspecting 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 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 pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a warm 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 few things:

  • 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 electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then use the vacuum to gently clean the metallic fins. These pieces are also called as condenser coils and divert heat away from your system.

You need to be cautious with these delicate coils. Warped or crinkled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also buy a fin comb from an appliance parts store. A pro from LTS Plumbing & Heating Inc. should fix severe damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard rubbish. Then wipe the inside of the system with a wet sponge.

The only coil cleaner you have to have 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 running like it should, give us a call at 570-648-0748.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the juice to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be replaced every few months, depending on the kind you use.

Can’t remember when you last put in a new one? Pull it out and tilt it toward the light. If you can’t see light through it, 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 pliable plastic tube. If it’s dirty, you can sanitize it by pouring thinned bleach through the tube to clean the line. Or you can replace the tube.

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