CoilSafe® + CoilSafe® Plus® Coatings
We apply CoilSafe® or CoilSafe® Plus® coatings directly to your HVAC coils to fight corrosion, preserve airflow, and extend your system’s life. These coatings help maintain optimal performance and reduce airborne contaminants that can impact indoor air quality.
ThermalBlock®
(or ThermalBlock by Coat Zone®) Coating
ThermalBlock® (or ThermalBlock by Coat Zone®) coating is applied to the HVAC unit’s cabinet, exposed ductwork, and rooftop areas—creating a durable, UV-resistant barrier that shields against weather, corrosion, and thermal transfer. It helps reduce heat load and improves long-term efficiency.

I am writing to recommend the services of Coat Zone®. They have performed multiple projects for us, which consist of coating coils on our admin buildings and condenser coil coating for our chillers in our gymnasium, as well as fan and housing coating for our laboratory fresh air makeup systems. The Rice facility team has always been completely satisfied. Coat Zone® does an excellent job. Their coatings and services have exceeded our expectations and have helped us reduce energy costs significantly. I am pleased to recommend the services of Coat Zone®.

Several months ago, I was approached by Coat Zone® regarding a dual coating process they developed to reduce kWh usage for HVAC units and block thermal heat on the cabinets. We proceeded to do a test at a medical building site in Houston, TX, and the results certainly far exceeded our expectations, as they achieved a 35% reduction in kWh usage. The numbers were truly impressive and will have a significant positive impact on reducing our cooling costs. We have since decided to proceed forward with a phase-in plan for all our buildings.

Coat Zone® implemented their coating process on all of our units. 60 days after the project was completed, we compared our power bills from the same month of the previous year. We discovered a 20% savings on our total power bill, which equals a 40% savings on our cooling cost (due to cooling only being 50% of our total power cost). We highly recommend Coat Zone®.
