Flushing the condenser, hoses and evaporator with refrigerant or an accredited solvent may well take away most of the particles. One particular aftermarket provider's A/C flush solvent, Dura 141, has seen profitable acceptance through the repair service sector. It's got a boiling level below ninety degrees Fahrenheit, so leaving residual solvent won't appear to be a dilemma. Nonetheless, fashionable parallel move flat tube condensers cannot be flushed correctly for the reason that debris jams during the slender tubes.

“But To optimize effectiveness, you’ll continue to ought to use weatherstripping round the perimeter with the unit. And always use the company’s installation and protection hardware.”
