When HVAC systems reach the end of their lifecycle or unexpected failures occur, downtime isn’t an option. For your customers, every hour matters. You need a partner who can expedite delivery to ensure they are satisfied and receive support as soon as possible. Coilmaster specializes in custom replacement coils designed to match original specifications, minimize downtime, and restore system performance quickly.
Why Replace Instead of Repair?
Repair might make sense for minor service issues, but coil damage typically points to a bigger performance problem. Corrosion, freeze damage, leaks, fin deterioration, or repeated cleaning failures can all reduce heat transfer and make the system work harder than it should have to. Meanwhile, a patched coil can keep a service team tied to the same unit instead of giving the customer a cleaner fix for the long haul.
Replacement is the smarter choice when downtime, labor cost, and energy use are the primary concerns. A properly measured replacement coil can match the original footprint, connection locations, circuiting, materials, and casing requirements, helping contractors, facility teams, and OEM service groups avoid ductwork changes, streamline installation, and restore the system with a component designed for current operating demands.

Featured Products for Aftermarket Coils
Fluid Coils
Coilmaster fluid coils are designed for air cooling or heating applications using chilled water, hot water or brine (e.g., ethylene or propylene glycol mixtures).
Steam Distributing Coils
Due to their tube-within-tube design, steam distributing coils provide a level of protection against freezing in low-temp applications.
Standard Steam Coils
An economical choice for general purpose or process heating, steam coils are the choice when inlet air temperatures will not fall below freezing.
Insulated Cased Coils
Our insulated cased coils are the most cost effective option on the market for complete, ready-to-install assembly—ideal for reducing labor time and simplifying installation in the field.
Evaporator Coils
Designed for use in comfort cooling, process cooling, and refrigeration, Coilmaster evaporator coils are proven for use with all of today’s refrigerants.
Condenser Coils
Our condenser coils are custom-designed to reject heat efficiently across a wide range of refrigerant applications.
Booster Coils
Our line of Booster Coils for hot water or low-pressure steam heating applications are pre-engineered for fast turnaround and reliable performance.
Industries & Applications
Coilmaster replacement coils are good for HVAC retrofits, commercial air handlers, industrial process systems, refrigeration equipment, schools, hospitals, office buildings, manufacturing facilities, and other critical environments. Whether the project entails a planned retrofit or an unexpected failure, our team works with contractors and equipment teams to replace coils without forcing major changes to the surrounding system.
