Tips for Cleaning Your AC System

With summer coming to an end in Richardson, now is an ideal time to get a kick start on air conditioner maintenance.

If you haven’t taken care of it this year, it could be clogged with dirt and yard refuse. This accumulation can reduce your unit’s efficiency and cause it to malfunction. Or make it wear out faster.

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

Regular AC maintenance also helps our technicians discover and handle slight issues before they become high-priced problems.

Some of the work we perform includes:

  • Inspecting the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Examining lines, refrigerant totals and connections

It’s not too late to have a tune-up done this fall—and we can get your furnace ready for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as a few pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a mild day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check the unit 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

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

2. Clean the Outside

Empty rubbish from the equipment. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to cautiously clean the metallic fins. These components are also referred to as condenser coils and divert heat away from your equipment.

You need to be cautious with these fine coils. Bent or crushed fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange warped fins. You can also get a fin comb from an appliance parts retailer. A pro from Hammack Service Company should fix severe damage.

4. Clean the Inside

After taking out the fan, fish out leaves and other yard litter. Then mop the inside of the equipment 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, showering water from the inside out. Reinstall the fan once you’re completed.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not running correctly, contact us a call at 972-351-8874.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the juice to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be replaced every several months, depending on the model you use.

Not sure when you last put in a new one? Pull it out and tilt it toward the light. If light isn’t 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 pliable plastic tube. If it’s moldy, you can sanitize it by pouring water-down bleach through the tube to flush the line. Or you can replace the tube.

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