Tips for Cleaning Your AC System

With summer winding down in Kingsville, now is an ideal time to get ahead on air conditioner maintenance.

If you haven’t taken care of it recently, it could be full of dirt and debris from your yard. This accumulation can reduce your unit’s efficiency and cause it to stop working. Or wear it down faster.

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

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

Some of the work we perform involves:

  • Inspecting the blower, motor, drain line and coils
  • Checking pressure and temperature
  • Testing lines, refrigerant levels and connections

There’s still time to have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some upkeep you can do on your own between professional tune-ups. You just need about an hour to clean your outdoor condenser unit, as well as a couple of components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a warm day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your system 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

Switch off the electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to cautiously clean the metallic fins. These components are also called as condenser coils and move heat away from your system.

You need to be considerate of these delicate coils. Bent or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also get a fin comb from an appliance parts website. A pro from Four Seasons Air Conditioning and Heating LLC should fix large amounts of damage.

4. Clean the Inside

After taking out the fan, dig out leaves and other yard litter. Then clean the inside of the equipment with a wet sponge.

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 finished.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not operating correctly, reach out to us a call at 361-214-1203.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be changed every several months, depending on the type you use.

Unsure when you last checked yours? Remove it and hold it up to the light. If light isn’t visible, 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 flexible plastic tube. If it’s scummy, you can clean it by draining diluted bleach through the tube to clean the line. Or you can get a new tube.

Clean the drain port using a small, round paintbrush. Connect the drain tube and switch the power back on.
