Tips for Cleaning Your AC System

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

If you haven’t washed it lately, it could be blocked with dirt and yard refuse. This accumulation can reduce your unit’s efficiency and cause it to break down. Or require replacement more quickly.

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

Consistent AC maintenance also helps our technicians spot and handle small issues before they turn into costly problems.

Some of the work we perform consists of:

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

You can still have a tune-up done this fall—and we can get your furnace prepared for heating season too.

There’s also some work you can do on your own between professional tune-ups. You just need about an hour to get the grime off your outdoor condenser unit, as well as several parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

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

2. Clean the Outside

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

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

You need to be careful with these fragile coils. Bent or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also get a fin comb from an appliance parts store. A pro from North Mechanical Heating and Cooling should take care of severe damage.

4. Clean the Inside

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

The only coil cleaner you need is water. Use light pressure from a hose nozzle to clean the fins, showering water from the inside out. Reinstall the fan 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 operating like it should, contact us a call at 928-263-8570.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be replaced every few months, depending on the kind you use.

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

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 clean it by flowing 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. Reconnect the drain tube and turn the power back on.
