Modular Blowers

Gas Furnaces & Heat Pumps Modular Blowers

The Modular Blowers for Gas Furnaces & Heat Pumps category is built for projects where you need a separate blower cabinet that can be paired with coils, gas furnaces, or heat pumps in a flexible way. Modular blowers let you configure the indoor side of a system in stages: blower today, coil or furnace tomorrow, or swap components in the future as refrigerants and efficiency standards change.

Unlike a traditional air handler, a modular blower is primarily a blower cabinet with motor, controls, and filter rack, designed to work with separate matching coils or as part of a modular furnace/coil stack. These units are common in tight closets, multi-family installs, and change-out jobs where cabinet footprint, duct connections, and service access are critical. Many models feature ECM or variable-speed motors to support higher SEER2/HSPF2 ratings with heat pumps or high-efficiency condensers.

• Modular blower cabinets that can be combined with cased coils and gas furnaces or used with dedicated evaporator coils for heat pumps.
• ECM and variable-speed blower options for better comfort, static handling, and humidity control with modern equipment.
• Multi-positional designs (upflow, downflow, horizontal) to fit closets, basements, and attic applications with limited space.
• Compatible coil and furnace matchups verified by OEM data so systems hit published efficiency ratings and capacities.
• Accessories and install kits including filter racks, transition panels, drain pans, float switches, and mounting hardware.

When you specify a modular blower for a gas furnace or heat pump, treat it as part of a complete system, not a standalone box. Confirm required airflow (CFM), external static pressure limits, cabinet dimensions, duct connection size, refrigerant type, and matched coil / furnace combinations. Use the Compare tools on this page to review blower motor type, CFM ranges, voltage, orientation, and filter options so you can avoid noise, low airflow, and efficiency losses after startup.

Pro tip: Before choosing a modular blower, sketch the mechanical area and note available width, depth, and height, return/supply locations, electrical access, and condensate routing. Identify whether the system will pair with a gas furnace, straight A/C coil, or heat pump. Share those details along with design CFM and static estimates and we can help you select the right modular blower model, coil match, and OEM accessory kit for a clean, serviceable installation that stays within manufacturer airflow limits.
