Tips for Cleaning Your AC System

With summer winding down in Tomball, now is a good time to get a head start on air conditioner maintenance.

If you haven’t washed it recently, it could be clogged with mud and yard waste. This buildup can decrease your unit’s efficiency and cause it to break down. Or require replacement sooner.

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

Consistent AC maintenance also helps our technicians discover and handle small issues before they turn into high-priced problems.

Some of the work we do involves:

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

There’s still time to have maintenance 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. You just need about an hour to wash your outdoor condenser unit, as well as several components on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a few things:

  • 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

Remove debris from the system. This includes branches, bushes, weeds and grass.

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

You need to be careful with these fine coils. Misshapen or crushed fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to adjust misshapen fins. You can also buy a fin comb from an appliance parts website. A pro from Premium Air Services LLC should handle severe damage.

4. Clean the Inside

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

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

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not running like it should, contact us a call at 713-364-9957.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

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

Not sure when you last checked yours? Pull it out and hold it up to the light. If there’s no light visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then inspect your air conditioner’s drain line—it’s a supple plastic tube. If it’s scummy, you can freshen it by pouring water-down bleach through the tube to flush the line. Or you can replace the tube.

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