1. one

   Purchase a pump sprayer, professional cleaning solution, and brush. Professional-form alkaline cleaning solution for evaporator coils will loosen clay and mold from inside the coils, the spray wand will reach the tight spaces inside the unit, and the bench brush will grab and hook dirt within the unit.

   • The pump sprayer should exist one U.s.a. gal (3.8 L) to two.5 Usa gal (9.five 50) and new, every bit quondam pump sprayers may have been used for poisons like weed killer or insecticide.
   • i US gal (three.viii L) sprayers work for routine cleaning and lightly soiled coils, while larger sprayers are all-time for heavy cleaning.

2. two

   Mix the cleaning solution and spray the coils. Follow product instructions for making the cleaning solution. one US gal (3.8 L) of spray should exist sufficient for a routine cleaning. The spray wand should be adjusted to a narrow .25 in (0.64 cm) spray, but the jet should non exist and then forceful that it bends the whorl fins. This is typically a business organization with pump sprayers larger than 2 U.s.a. gal (7.6 Fifty).

   • Afterwards, give the coils a few minutes to dry out.
   • Brand sure you lot tin see the muddied cleaning solution running downwards to the condensate drain pan.
   • To peel off clumps of droppings, you may accept to direct the spray at the coils from a low bending.

3. 3

   Brush the coils, rinsing the brush often. The brush should be rinsed in a new bucket of make clean water to ensure at that place are no residual chemicals or dirt being added to the coils. The brush picks off chunks of dirt and droppings too stubborn to exist removed by the spray. Never brush across the fins, which can cause them to fold and bend. This will event in blocked air catamenia.

   • Brusk brush strokes ensure your brushing motions will be precisely directly upwardly and downwardly.

   Mix warm water and dishwashing detergent in a spray bottle. Use merely a few drops of detergent, and brand certain the detergent is not highly acidic. Acidic cleaners tin crusade corrosion to the copper and other metals used in the coil and shorten the life of the coil.^[5]

   • You can too use a manus sprayer or garden sprayer.

2. 2

   Spray the water/detergent solution onto the evaporator coils. Give the solution a few seconds to a few minutes to soak in and loosen debris. Reapply if needed. You lot tin let the coil to either drain naturally, or lightly rinse information technology with some water.^[6]

3. iii

   Wipe away loose material with a soft material or castor. Be careful non to bump the fins on the A-frame, as this may bend them. If you cull to wipe the fins, never wipe them horizontally, equally they may fold and later cake air flow.^[7]

3. 3

   Pour 1 United states of america qt (0.95 L) of a bleach/water solution into the drain pan. The bleach and water solution should be half household bleach and half water.

   Pour water down the condensate drain tube. This tube leads abroad from the bleed pan. This will help y'all verify the tube is draining properly. If information technology seems the tube is blocked (indicated by something like continuing h2o in the drain pan), discontinue use of the air-conditioning system and phone call an HVAC contractor to clear the blockage.
