Tips for Cleaning Your AC System in Dallas

With summer coming to an end in Dallas, 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 full of dust and yard waste. This accumulation can limit your unit’s efficiency and cause it to malfunction. Or require replacement more quickly.

We advise 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 utility expenses.

Consistent AC maintenance also helps our technicians spot and address small issues before they become costly problems.

Some of the work we complete consists of:

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

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

There’s also some maintenance you can do by yourself between professional tune-ups. You just 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

Select a warm 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 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

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

2. Clean the Outside

Take out 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 referred to as condenser coils and divert heat away from your equipment.

You need to be considerate of these delicate coils. Misshapen or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to adjust warped fins. You can also get a fin comb from an appliance parts retailer. A pro from Tri County Air Care LLC should take care of extensive damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard litter. Then wipe the inside of the system with a wet cloth.

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Put the fan back in 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, contact us a call at 469-213-8367.

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

Can’t remember when you last replaced yours? Pull it out and angle 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 examine your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can freshen 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. Reconnect the drain tube and switch the power back on.
