When an HVAC coil begins leaking, corrodes or can no longer provide the heating or cooling your building needs, replacing the complete system may not be necessary. Emergent Coils provides commercial HVAC replacement coils for existing heating and cooling equipment.

We offer replacement coils designed to meet the dimensions, connection requirements and operating conditions of commercial HVAC systems.

Replacement Coils for Commercial HVAC Systems

HVAC coils transfer heat between air and the water, steam or refrigerant moving through the coil. They play an essential role in maintaining indoor temperatures in commercial buildings.

Over time, corrosion, freezing, fouling and physical damage can affect coil performance. A leaking or deteriorated coil may reduce system capacity, interrupt building operations and increase maintenance needs.

Replacing the affected coil can help restore heating or cooling performance while allowing serviceable equipment to remain in use.

Commercial HVAC Replacement Coil Options

Emergent Coils supplies replacement coils for a variety of heating and cooling applications, including:

• Chilled water coils
• Hot water coils
• Evaporator coils
• Condenser coils
• Steam coils
• Steam distributing coils
• Reheat coils
• Custom replacement coils

The appropriate coil depends on the equipment, heating or cooling medium, available space and performance requirements of the application.

Replacing an Existing Commercial HVAC Coil

The manufacturer, model number and serial number of your existing equipment are useful starting points when identifying a replacement coil.

When additional information is needed, photographs and field measurements can help document the existing coil. Important details may include finned height and length, number of rows, overall casing dimensions, connection sizes and locations, airflow direction and operating conditions.

Emergent Coils provides blank coil drawings to help contractors and maintenance teams record dimensions in the field.

Confirming these details before ordering helps ensure the replacement fits the equipment and meets the requirements of the system.

OEM Replacement HVAC Coils

Emergent Coils supplies OEM replacement coils for numerous commercial equipment brands and configurations.

Replacement options include coils for equipment from manufacturers such as Carrier, Trane, York, AAON, Lennox and others. The existing equipment information helps determine the replacement needed for a particular application.

If the original coil is obsolete or difficult to source, a replacement may be available based on the existing coil’s dimensions, construction and performance requirements.

Coil Materials and Construction

Selecting the correct materials and construction is an important part of replacing a commercial HVAC coil.

Tube and fin materials, fin spacing, row count, casing construction and connection configuration can affect fit, heat transfer and maintenance access. Operating pressures, temperatures and exposure to corrosive conditions also need to be considered.

Our team can review your existing equipment information to help determine the requirements for your replacement coil.

Frequently Asked Questions

Can you replace an HVAC coil without replacing the entire system?

Yes, in many commercial HVAC systems, an individual coil can be replaced while the remaining equipment stays in service. The condition of the equipment, coil accessibility and system requirements help determine whether coil replacement is appropriate.

How do I identify the correct commercial HVAC replacement coil?

Start with the equipment manufacturer, model number and serial number. Photographs, coil dimensions, connection details and operating information may also be needed to confirm the correct replacement.

What types of commercial HVAC coils does Emergent Coils supply?

Emergent Coils supplies chilled water, hot water, evaporator, condenser, steam, steam distributing and reheat coils, along with custom replacement options for existing equipment.

What causes a commercial HVAC coil to fail?

Common causes include corrosion, freezing, vibration, physical damage and operation outside the coil’s design conditions. Dirt and buildup can also restrict airflow and reduce heat transfer, even when the coil is not leaking.

Can an obsolete commercial HVAC coil be replaced?

In many cases, yes. When the original coil is no longer readily available, a replacement can often be identified or manufactured using equipment specifications, field measurements and operating requirements.
