Tips for Cleaning Your AC System

September 20, 2019

With summer coming to an end in Huntsville, 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 dust and yard refuse. This accumulation can decrease your unit’s efficiency and cause it to malfunction. Or make it wear out faster.

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

Regular AC maintenance also helps our technicians spot and handle slight issues before they turn into high-priced problems.

Some of the work we perform involves:

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

It’s not too late 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 on your own between professional tune-ups. You just need about an hour to wash your outdoor condenser unit, as well as several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a temperate day to wash 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

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

Then use the vacuum to gently 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 fragile coils. Misshapen or crinkled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also buy a fin comb from an appliance parts website. A pro from All Weather Heating & Air Conditioning Inc should fix large amounts of damage.

4. Clean the Inside

After extracting the fan, pull out leaves and other yard litter. Then wipe the inside of the system with a wet sponge.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to clean the fins, spraying water from the inside out. Put the fan back in 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 operating properly, reach out to us a call at 256-801-4701.

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 should be exchanged every few months, depending on the kind you use.

Can’t remember when you last put in a new one? Remove it and angle it toward the light. If light isn’t visible, buy a new one.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then examine your air conditioner’s drain line—it’s a supple plastic tube. If it’s moldy, you can freshen it by draining thinned bleach through the tube to clean the line. Or you can get a new tube.

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