Tips for Cleaning Your AC System in New Castle

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

If you haven’t washed it this year, it could be blocked with dirt and yard waste. This accumulation can decrease your unit’s efficiency and cause it to break down. Or require replacement sooner.

We advise having your air conditioning system professionally maintained every year. Why? Clean equipment can be more energy efficient, which could save you money on electric costs.

Regular AC maintenance also helps our technicians spot and take care of slight issues before they turn into expensive problems.

Some of the work we do includes:

  • Viewing the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Examining 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 alone between professional tune-ups. You only need about an hour to get the grime off your outdoor condenser unit, as well as a few components on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a handful of tools:

  • 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 power 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 use the vacuum to cautiously clean the metallic fins. These pieces are also referred to as condenser coils and move heat away from your unit.

You need to be cautious with these fragile coils. Misshapen or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also get a fin comb from an appliance parts store. A pro from Central Heating & Plumbing should fix severe damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard litter. Then clean the inside of the unit with a wet sponge.

The only coil cleaner you should use is water. Use gentle pressure from a hose nozzle to clean the fins, showering water from the inside out. Put the fan back in 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 running correctly, reach out to us a call at 724-401-1843.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

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

2. Check Your Filter

Furnace filters must be exchanged every few months, depending on the kind you use.

Can’t remember when you last checked yours? Take it out and tilt it toward 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 supple plastic tube. If it’s dirty, you can sanitize it by pouring diluted bleach through the tube to clean the line. Or you can replace the tube.

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