Tips for Cleaning Your AC System in Oxford

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

If you haven’t cleaned it lately, it could be blocked with dirt and yard waste. This collection can decrease your unit’s efficiency and cause it to stop working. Or wear it down more quickly.

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

Consistent AC maintenance also helps our technicians locate and address small issues before they become costly problems.

Some of the work we complete includes:

  • Viewing the blower, motor, drain line and coils
  • Confirming 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 prepped for heating season too.

There’s also some work you can do on your own between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a couple of pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a mild day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run the unit once you’ve cleaned it.

You’ll only need a couple of 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 electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then use the vacuum to cautiously clean the metallic fins. These pieces are also called as condenser coils and divert heat away from your unit.

You need to be careful with these fragile coils. Bent or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also buy a fin comb from an appliance parts retailer. A pro from Franklin's Heating & Air Conditioning, Inc. should handle large amounts of damage.

4. Clean the Inside

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

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. Replace the fan once you’re finished.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not running correctly, reach out to us a call at 662-350-0343.

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 must be changed every couple of months, depending on the type you use.

Not sure when you last put in a new one? Take it out and hold it up to the light. If light isn’t visible, get a new one.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then take a look at your air conditioner’s drain line—it’s a flexible plastic tube. If it’s scummy, you can clean it by draining thinned bleach through the tube to clean the line. Or you can buy a new tube.

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