Tips for Cleaning Your AC System

With summer coming to an end in Denton, 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 accumulation can reduce your unit’s efficiency and cause it to break down. Or require replacement more quickly.

We advise 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 bills.

Routine AC maintenance also helps our technicians spot and address small issues before they turn into high-priced problems.

Some of the work we perform consists of:

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

You can still have service done this fall—and we can get your furnace prepared for heating season too.

There’s also some upkeep you can do alone 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

Pick a warm day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your equipment once you’ve cleaned it.

You’ll only need a few tools:

  • 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

Take out debris from the equipment. This includes branches, bushes, weeds and grass.

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

You need to be considerate of these fine coils. Bent or crinkled 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 Oak Point Heating and Air LLC should fix large amounts of damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard rubbish. Then wipe the inside of the unit with a wet rag.

The only coil cleaner you need 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 finished.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating correctly, contact us a call at 940-202-1202.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be exchanged every couple of months, depending on the kind you use.

Not sure when you last replaced yours? Take it out and hold it up to the light. If light isn’t visible, get 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 supple plastic tube. If it’s moldy, you can clean it by pouring diluted bleach through the tube to sanitize the line. Or you can buy a new tube.

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