Tips for Cleaning Your AC System in McHenry

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

If you haven’t cleaned it lately, it could be blocked with mud and yard refuse. This collection can decrease your unit’s efficiency and cause it to break down. Or wear it down sooner.

We advise having your air conditioning system professionally maintained once a year. Why? A clean system can be more energy efficient, which could save you money on utility costs.

Routine AC maintenance also helps our technicians spot and address small issues before they become expensive problems.

Some of the work we do includes:

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

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

There’s also some work you can do alone between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a temperate day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run your equipment once you’ve cleaned it.

You’ll only need a handful 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

Switch off the juice to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to slowly clean the metallic fins. These parts are also referred to as condenser coils and transfer heat away from your system.

You need to be considerate of these fine coils. Warped or crinkled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange warped fins. You can also get a fin comb from an appliance parts retailer. A pro from Jett's Heating & Air Inc. should handle severe damage.

4. Clean the Inside

After taking out the fan, fish out leaves and other yard litter. Then clean the inside of the unit with a wet cloth.

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to rinse the fins, spraying water from the inside out. Put the fan back in once you’re done.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not running like it should, contact us a call at 815-410-1128.

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 must be replaced every several months, depending on the kind you use.

Can’t remember when you last checked yours? Pull 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 examine your air conditioner’s drain line—it’s a supple plastic tube. If it’s dirty, you can freshen it by pouring water-down bleach through the tube to clean the line. Or you can replace the tube.

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