Tips for Cleaning Your AC System in Pacheco

With summer winding down in Pacheco, now is an ideal time to get a head start on air conditioner maintenance.

If you haven’t cleaned it this year, it could be blocked with mud and debris from your yard. This accumulation can decrease your unit’s efficiency and cause it to stop working. Or make it wear out more quickly.

We suggest having your air conditioning system professionally tuned-up every year. Why? A clean unit can be more energy efficient, which could save you money on utility costs.

Regular AC maintenance also helps our technicians discover and handle small issues before they become high-priced problems.

Some of the work we perform includes:

  • Inspecting the blower, motor, drain line and coils
  • Watching 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 prepped for heating season too.

There’s also some work you can do on your own between professional tune-ups. It only takes about an hour to wash 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 great. That way, you can run the unit once you’ve cleaned it.

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

2. Clean the Outside

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

Then use the vacuum to gently clean the metallic fins. These components are also called as condenser coils and move heat away from your unit.

You need to be cautious with these delicate coils. Warped or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also get a fin comb from an appliance parts store. A pro from Clean Air HVAC should take care of large amounts of damage.

4. Clean the Inside

After taking out the fan, pull out leaves and other yard waste. Then clean the inside of the system with a wet sponge.

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. Put the fan back in once you’re done.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not running properly, give us a call at 925-233-6238.

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 must be changed every few months, depending on the model you use.

Not sure when you last put in a new one? Take it out and hold it up to the light. If light isn’t visible, buy 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 scummy, you can clean it by pouring thinned bleach through the tube to flush the line. Or you can replace the tube.

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