Tips for Cleaning Your AC System

With summer winding down in West Valley City, now is a great time to get a kick start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be blocked with dust and yard refuse. This buildup can decrease your unit’s efficiency and cause it to stop working. Or make it wear out 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 energy expenses.

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

Some of the work we complete includes:

  • Taking a look at the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Reviewing lines, refrigerant levels and connections

It’s not too late to have maintenance done this fall—and we can get your furnace prepared for heating season too.

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

How to Clean Your Outside AC Unit

Choose a mild day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can check your equipment once you’ve cleaned it.

You’ll only need a handful of 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

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

2. Clean the Outside

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

Then run the vacuum to gently clean the metallic fins. These components are also referred to as condenser coils and move heat away from your equipment.

You need to be careful with these delicate coils. Bent or crushed fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also use a fin comb from an appliance parts retailer. A pro from Select Comfort System Heating & Air Conditioning should handle extensive damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard rubbish. Then clean the inside of the equipment with a wet cloth.

The only coil cleaner you need is water. Use light pressure from a hose nozzle to rinse the fins, showering water from the inside out. Replace the fan once you’re done.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not working correctly, contact us a call at 801-305-4777.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be changed every several months, depending on the type you use.

Not sure when you last put in a new one? Pull it out and angle 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 take a look at your air conditioner’s drain line—it’s a pliable plastic tube. If it’s scummy, you can clean it by pouring water-down bleach through the tube to sanitize the line. Or you can replace the tube.

Wash the drain port using a small, round paintbrush. Hook up the drain tube and switch the power back on.
