Replacement Coil

Emergent Coils specializes in replacement of malfunctioning, worn out, and leaking commercial and industrial HVAC coils.

Replacement Coil Information

Every single day coils go out of service. It's a fact of life in HVAC. Tubes can burst from freezing, tubes can erode from the inside, fins can corrode from harsh airstreams... the list goes on and on.

The life expectancy of a commercial coil is between 7-10 years. Repairing coils can keep them going for a while, but will reduce heat transfer each time.

Every single day we help customers replace their failing or worn out coils. Whatever the reason, location, or application we can help you replace your commercial or industrial air coil.

We currently replace these coil types:
  • Chilled water (or glycol)
  • Hot water (or glycol)
  • Direct expansion
  • Condenser
  • Reheat
  • Steam
We commonly replace coils for:
  • Schools
  • Offices
  • Restaurants
  • Theaters
  • Manufacturing Plants
We provide coils to anyone:
  • Contractors
  • Building Owners
  • Facility Managers
  • Building Maintenance

Replacement Coil Performance

Coil performance varies greatly from application to application. Flow rates and temperatures for both fin and tube sides will greatly influence the performance characteristics for any given coil.

We have state of the art software that we can use to quote performance. For a detailed performance run tailored to your situation, please email sales@emergentcoils.com with as many of the following details as you have available:

  • Coil model number
  • Duct size
  • Air Flow Rate in CFM (cubic feet per minute)
  • Entering Air Dry Bulb Temperature in °F
  • Entering Air Wet Bulb Temperature in °F (cooling coils only)
  • Fluid flow rate in GPM (gallons per minute, for water coils only)
  • Entering fluid temperature in °F
  • Desired capacity in MBH or tons
  • Desired leaving air temperature in °F
