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. Pairing your coils with the right HVAC controls keeps temperatures and airflow dialed in long after installation. Facilities with tighter uptime requirements, like data centers, often pair coils with a full data center cooling system built around EC fan arrays and N+1 redundancy.

Duct reheat coils are used with hot water or steam for general heating applications. They are relatively easy to install. There are usually upstream coils…
Condenser coils are used in a wide variety of HVAC heat recovery and condensing applications. These coils typically consist of between 1-4 rows of tubes.
Most commercial coil work comes down to four types. Which one you need follows the medium the building already distributes, and whether the coil is heating or cooling the air.
| Coil type | Medium | Typical duty |
|---|---|---|
| Chilled water coils | Chilled water | Cooling and dehumidification in air handlers |
| Hot water coils | Hot water | Heating, preheat and freeze protection |
| Steam coils | Steam | Heating where steam is already distributed |
| Evaporator (DX) coils | Refrigerant | Direct expansion cooling without a chilled water plant |
Going deeper on any one of them: our guide to chilled water coils covers how they work and how to size one; the steam coils page covers sizing and non-freeze construction; reheat coils compares hot water against steam at the zone level; and tube bundle replacement walks through field measuring and OEM cross-referencing.
Beyond those four we also build split core coils, condenser coils, industrial coils, coil boxes and heat exchangers — all field-measured and cross-referenced to the original manufacturer’s specs.
