Coil Coating

Because CAHS has partnered up with Infiniti Coatings LLC, we can apply a protective coating to your HVAC equipment coils and cabinets to increase their life up to 85%. This process also produces the following benefits: reduces your Air Conditioning Energy cost from 10% to 25%, controls degradation of equipment surfaces due to corrosion, and improves indoor air quality by getting rid of ‘dirty sock’ syndrome.
