Coil Cleaner is a specialized chemical solution used to remove dirt, grease, and oxidation from the fins of an evaporator or condenser coil. Regular use of coil cleaner is essential for maintaining the SEER2 efficiency of your Single-Zone system. If the coils are dirty, they cannot transfer heat effectively, which forces the compressor to run longer and harder. We offer coil cleaning Accessories that are safe for use with our anti-corrosive "Gold Fin" coatings. For Multi-Zone outdoor units, a seasonal cleaning can prevent "short-cycling" and high energy bills. This simple maintenance task is one of the best ways to protect your Compressor Warranty. It is a standard part of any professional HVAC service visit. Keeping your coils "OLMO clean" ensures that your system provides the crisp, cold air you expect. It is a vital step in ensuring the long-term "Reliability" of your investment.
