Types of Coils
Though we specialize in the custom design and manufacture of air handling units, systems, and equipment, our family business started in Northern New Jersey with the manufacture of HVAC components and replacement coils. If you need custom replacement HVAC coils or replacement tube bundles, you need only send us the information associated with your heat exchanger or HVAC system. We can then provide you with a quote for a replacement that meets or even exceeds the quality of the original manufacturer’s coils.
Mainstream’s outstanding responsiveness, along with our experience and extensive knowledge of coils, makes us your best option for all your coil needs. Here you can find our wide selection of replacement HVAC coils and heat exchanger replacement tube bundles.
The Fastest Lead Times in the Industry
Mainstream can offer as fast as 24 hour lead times on most coils.
