Tips for Cleaning Your AC System

With summer ending in Grand Prairie, now is a great time to get ahead on air conditioner maintenance.

If you haven’t taken care of it recently, it could be blocked with dirt and debris from your yard. This collection can limit your unit’s efficiency and cause it to malfunction. Or wear it down faster.

We suggest having your air conditioning system professionally tuned-up every year. Why? A clean unit can be more energy efficient, which could save you money on energy expenses.

Routine AC maintenance also helps our technicians spot and handle small issues before they develop into costly problems.

Some of the work we complete includes:

  • Viewing the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Reviewing lines, refrigerant levels 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 upkeep you can do by yourself between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a few pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a mild day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can test your equipment 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 power to your air conditioner at the breaker box.

2. Clean the Outside

Take out waste from the system. This includes branches, bushes, weeds and grass.

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

You need to be careful with these delicate coils. Misshapen or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also use a fin comb from an appliance parts retailer. A pro from Mustang Mechanical should take care of extensive damage.

4. Clean the Inside

After taking out the fan, pull out leaves and other yard litter. Then clean the inside of the unit with a wet cloth.

The only coil cleaner you have to have is water. Use slight 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 working like it should, reach out to us a call at 972-445-9504.

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 changed every several months, depending on the model you use.

Unsure when you last checked yours? Pull it out and angle 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 take a look at your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can clean it by draining water-down 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 restore power.
