Here are the major benefits of a new unit versus rehabilitating the old unit:

• New double wall 2" insulated housings versus single wall matted and torn insulation
• Double wall sealed and latched access doors that will replace those old removable panels that are now taped onto the unit because the screws are stripped
• Internal vibration isolation with 2" deflection springs and internally mounted motors
• Hi efficiency motors versus standard duty, inefficient motors
• Variable Frequency Drives (VFD) that reduce operation expense by reducing air flow during non-peak periods
• Energy efficient fan selection to include plenum and fan array arranglements
• Stainless steel drain pans versus rusted out galvanized steel pans

• Energy efficient, cleanable heating and cooling coils that will match the actual performance of the unit today versus the arbitrary design from 30 years ago
• Space (if available) between components for ease in monitoring and servicing
• Low leakage dampers for mixing of outside and return air versus leaky damper sets
• high efficiency filters with lower air velocity versus the panel inefficient furnace filters
• Monitoring windows and lights in almost any section along with GFI outlets for servicing
• UV light mounted downstream of cooling coil to reduce bacteria growth from the dehumidifying process
