Arguably the most effective step in maintaining a residential AC unit is cleaning the outdoor condenser unit. It prolongs the life of the equipment and gives residents more bang from their cooling buck. But ineffective cleaning can actually cause problems, packing dirt and debris into the unit, and damaging those all-important fins.

Remember these tips for effective AC condenser coil cleaning:

  • Clean coils from the inside as well as the outside. Directing water into the unit can actually pack debris deeper into the coils. It’s important to first direct your water spray against the direction of air flow through the coil. This pushes the dirt back out the way it came in. Then hot the outside with a rinse off.
  • Beware of pressure washers. You can make a real mess of fins with a pressure washer. The fins on many coils bend at about 140 psi – most pressure washers push out a minimum of 600 psi and some go into the thousands. More isn’t always better.

SpeedClean’s Condenser Needle makes it easy to clean a condenser unit the right way. Its narrow, low profile and high-grade aluminum wand fits easily through small or slanted openings at the top of the condenser grate. Most of the time you won’t even need to remove the grate and fan unit! The unique 90-degree spray pattern effectively blasts dirt directly out of the unit without damaging the fins, and it minimizes the risk of electrical trips and shorts. You can easily clean a 5 to 10 ton unit in as little as 5 minutes.

The Condenser Needle is lightweight and portable. It attaches quickly to any standard water hose, giving you up to 3 gallons a minute of effective, directed cleaning power. It comes with everything you need to get started – 36” wand with connector, spray gun garden hose connector with flow back control, adjustable chemical injection hose (for optional use of SpeedyFoam® biodegradable coil cleaning solution) and instructions.

The Condenser Needle is also ideal for rooftop condenser units and refrigerated vehicle units, where portability is essential.
