Tips for Cleaning Your AC System

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

If you haven’t washed it this year, it could be blocked with mud and yard refuse. This accumulation can decrease your unit’s efficiency and cause it to stop working. Or make it wear out faster.

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 high-priced problems.

Some of the work we perform consists of:

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

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

There’s also some work you can do on your own between professional tune-ups. You only need about an hour to wash 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 best. That way, you can run your equipment once you’ve cleaned it.

You’ll only need a couple of 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 equipment. This includes branches, bushes, weeds and grass.

Then use the vacuum to cautiously clean the metallic fins. These components are also called as condenser coils and divert heat away from your unit.

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

3. Fix Bent Fins

Use a butter knife to adjust warped fins. You can also buy a fin comb from an appliance parts website. A pro from Tri County Air Care LLC should fix severe damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to rinse the fins, spraying water from the inside out. Reinstall the fan once you’re completed.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not running correctly, reach out to us a call at 469-213-8367.

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 exchanged every few months, depending on the model you use.

Can’t remember when you last replaced yours? Pull it out 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 dirty, you can freshen it by pouring thinned bleach through the tube to sanitize the line. Or you can replace the tube.

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