Tips for Cleaning Your AC System

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

If you haven’t taken care of it this year, it could be blocked with dust and debris from your yard. This collection can decrease your unit’s efficiency and cause it to stop working. Or require replacement sooner.

We recommend 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 electric expenses.

Consistent AC maintenance also helps our technicians locate and handle slight issues before they develop into expensive problems.

Some of the work we perform consists of:

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

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

There’s also some upkeep you can do on your own between professional tune-ups. It only takes about an hour to get the grime off 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 mild day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can test your system once you’ve cleaned it.

You’ll only need a couple of 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 juice to your air conditioner at the breaker box.

2. Clean the Outside

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

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

You need to be cautious with these fine coils. Warped or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also buy a fin comb from an appliance parts website. A pro from County Line Mechanical LLC should handle extensive damage.

4. Clean the Inside

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

The only coil cleaner you need is water. Use gentle pressure from a hose nozzle to rinse 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 running like it should, reach out to us a call at 717-216-0846.

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 need to be replaced every few months, depending on the model you use.

Can’t remember when you last checked yours? Remove it 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 examine your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can clean it by draining thinned bleach through the tube to flush the line. Or you can replace the tube.

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