Tips for Cleaning Your AC System

With summer winding down in Hamilton, now is a great time to get ahead on air conditioner maintenance.

If you haven’t taken care of it lately, it could be clogged with dust and yard refuse. This buildup can limit your unit’s efficiency and cause it to break down. Or wear it down more quickly.

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

Consistent AC maintenance also helps our technicians discover and take care of slight issues before they develop into costly problems.

Some of the work we do includes:

  • Taking a look at the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Examining lines, refrigerant totals and connections

You can still have a tune-up done this fall—and we can get your furnace prepared for heating season too.

There’s also some upkeep you can do by yourself between professional tune-ups. You only need about an hour to get the grime off your outdoor condenser unit, as well as a few parts 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 run 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 juice to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to slowly clean the metallic fins. These components are also referred to as condenser coils and move heat away from your equipment.

You need to be cautious with these fine coils. Bent or crinkled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also get a fin comb from an appliance parts website. A pro from Carefree Heating and Cooling, LLC should fix extensive damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard rubbish. Then clean the inside of the unit with a wet cloth.

The only coil cleaner you need is water. Use gentle pressure from a hose nozzle to rinse the fins, showering water from the inside out. Put the fan back in once you’re finished.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not running properly, contact us a call at 513-268-5164.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

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

2. Check Your Filter

Furnace filters should be replaced every few months, depending on the type you use.

Unsure when you last put in a new one? Pull it out and tilt it toward the light. If there’s no light visible, replace it.

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 freshen it by flowing water-down bleach through the tube to sanitize the line. Or you can buy a new tube.

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