Tips for Cleaning Your AC System in Mobile

With summer ending in Mobile, now is a good time to get a head start on air conditioner maintenance.

If you haven’t cleaned it this year, it could be blocked with mud and yard waste. This buildup can decrease your unit’s efficiency and cause it to stop working. Or require replacement more quickly.

We recommend having your air conditioning system professionally tuned-up once a year. Why? Clean equipment can be more energy efficient, which could save you money on utility costs.

Consistent AC maintenance also helps our technicians spot and handle minor issues before they develop into high-priced problems.

Some of the work we do includes:

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

You can still have maintenance done this fall—and we can get your furnace prepped for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. You just 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 mild day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can run the unit 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

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

Then run the vacuum to slowly clean the metallic fins. These components are also called as condenser coils and divert heat away from your unit.

You need to be cautious with these delicate coils. Misshapen or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also use a fin comb from an appliance parts website. A pro from Farnell Heating & Air Conditioning Inc should fix large amounts of damage.

4. Clean the Inside

After taking out the fan, dig out leaves and other yard rubbish. Then mop the inside of the system with a wet rag.

The only coil cleaner you should use is water. Use gentle pressure from a hose nozzle to clean the fins, directing water from the inside out. Put the fan back in once you’re completed.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not working like it should, contact us a call at 251-210-7178.

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 replaced every couple of months, depending on the model you use.

Can’t remember when you last replaced yours? Take it out and tilt it toward the light. If you can’t see light through it, get a new one.

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 moldy, you can clean it by pouring diluted bleach through the tube to sanitize the line. Or you can replace the tube.

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