Your HVAC system is critical to the operation of your business or property. You want your system to last as long as possible. One of the most critical parts of an HVAC system is the coil or heat exchanger. These components are critical because they are what transfer the heat, which keeps your building comfortable.

In certain environments (marine, industrial, agricultural, or areas where there are harsh chemicals) the heat changers can corrode very quickly, losing efficiency and capacity. This can be very costly in terms of energy consumption and can cause expensive repair bills.

The solution to this problem is applying a protective coating. We apply several different coil coatings to protect HVAC coils from corroding, to add life to your air conditioning and heating system and help it maintain its efficiency.
