Nu-CalgonTri-Pow'r HD 4371-88 Cleaner for condensers, evaporator coils, permanent filters, fan blades, motors

Keep your coils clean and your AC running longer with this coil cleanerUsed with coil cleaning canon hooked to regular garden hose and pressure.Works best if you remove the top fan and spray from the inside outI used 3:1 ratio which is a dual on the coil canon8-12oz is plenty for annual regularly maintained unit.

This was my second order for this product because the first order went so well. This product works great for cleaning the algae and gunk off evaporator coils. It also cleans mold and algae off the exterior of the evaporator housing and out of the condensate drain line. Regarding the shipping service, I really appreciate the thought and effort that went into packing the product so it would not leak during shipment: cap taped down so it would not come off; bottle double-bagged to contain any potential leaks; all four sides of the shipping carton had high-visibility labels indicating “This Side Up”. All small things that make a big difference in ensuring the product arrives as shipped. Finally, thank you for NOT shipping USPS. They have had major (as in weeks or months) delays delivering mail to the Southeast this year.

Worth every dime. This product is the only one that really cleans out the coils in your A/C.

4-stars because the bottle leaked 1/3 of the cleaner into the double bagged packaging in the box. Had to try to pour the 2-bags of cleaner back into the bottle without making a mess. Glad it was double bagged since first bag leaked out, too.

This one is one of the best I have used. Do not use full strength, cut it with water.

It was great

My AC company told me about this and it does work to keep the drain clean . You only need a half once to a gal and pour it down your ac drain line

Great product at a great price,easy to use smells great and works awsome on micro channel coils!
