Tips for Cleaning Your AC System

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

If you haven’t taken care of it this year, it could be full of dust and debris from your yard. This buildup can limit your unit’s efficiency and cause it to malfunction. Or wear it down faster.

We recommend having your air conditioning system professionally maintained every year. Why? A clean unit can be more energy efficient, which could save you money on electric bills.

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

Some of the work we perform includes:

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

It’s not too late to 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. 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

Select a temperate day to wash 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 couple of 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

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

2. Clean the Outside

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

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

You need to be careful with these fine coils. Warped or crinkled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also buy a fin comb from an appliance parts retailer. A pro from B&D Air Conditioning should handle extensive damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard waste. Then clean the inside of the unit with a wet sponge.

The only coil cleaner you have to have is water. Use gentle pressure from a hose nozzle to rinse 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 properly, contact us a call at 928-432-6018.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut 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 kind you use.

Unsure when you last replaced yours? Take 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 scummy, you can sanitize it by pouring thinned bleach through the tube to clean the line. Or you can buy a new tube.

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