Tips for Cleaning Your AC System in Northglenn

With summer coming to an end in Northglenn, now is a good time to get a head start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be full of dust and yard refuse. This collection can decrease your unit’s efficiency and cause it to break down. Or make it wear out sooner.

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 expenses.

Routine AC maintenance also helps our technicians discover and address slight issues before they develop into costly problems.

Some of the work we perform includes:

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

There’s still time to have service done this fall—and we can get your furnace prepared for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. It only takes about an hour to clean your outdoor condenser unit, as well as a few parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a temperate day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is great. That way, you can check 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

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

2. Clean the Outside

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

Then use 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 cautious with these delicate coils. Misshapen or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also buy a fin comb from an appliance parts retailer. A pro from Northglenn Heating & Air Conditioning, Inc. should handle extensive damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard rubbish. Then wipe the inside of the system with a wet cloth.

The only coil cleaner you should use is water. Use slight pressure from a hose nozzle to clean the fins, showering water from the inside out. Put the fan back in 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 properly, contact us a call at 303-452-4146.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be changed every several months, depending on the model you use.

Can’t remember when you last put in a new one? Remove it and tilt it toward the light. If there’s no light visible, replace it.

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 sanitize it by pouring water-down bleach through the tube to flush the line. Or you can buy a new tube.

Clean the drain port using a small, round paintbrush. Connect the drain tube and restore power.
