Factory-Installed TXV Kit: Installation Made Easier
The FVM4X4800BL comes with a pre-installed Thermal Expansion Valve (TXV) kit, saving your installer time and you money. This feature allows for more precise refrigerant control, optimizing system efficiency regardless of outdoor conditions.
FVM4X4800BL Compatibility and System Integration
The FVM4X4800BL is a versatile component that works seamlessly with various HVAC setups:
- Compatible with both AC-only and heat pump condensers
- Equivalent to Carrier model FV4CNF005L00
- Equivalent to Bryant model FV4CNF005L00
- Equivalent to Tempstar model FVM4X4800BL
This cross-compatibility gives you flexibility when selecting other system components or when replacing just your air handler in an existing setup.
Electric Heat Options for the FVM4X4800BL
The FVM4X4800BL supports optional electric heat kits that can be field-installed. These kits provide supplemental heating for heat pump systems or can be used for primary heating in electric-only installations. Available options include:
- 5 kW heat kit
- 8 kW heat kit
- 10 kW heat kit
- 15 kW heat kit
- 20 kW heat kit
- 25 kW heat kit
- 30 kW heat kit
This range of options ensures you can match your heating needs precisely, whether you need just a little extra warmth during occasional cold snaps or reliable primary heating for colder climates.
Durability and Build Quality of the FVM4X4800BL
The FVM4X4800BL is built to last with its one-piece heavy-duty outer casing that protects all internal components. This robust construction helps shield the vital parts from damage during installation and throughout the unit’s operational life.
ACiQ designed this air handler for reliability, with UL certification providing additional assurance of quality and safety standards.
Warranty Protection for Your FVM4X4800BL Investment
ACiQ stands behind the FVM4X4800BL with impressive warranty coverage:
- 10-year no-hassle replacement warranty
- 10-year parts warranty (with product registration)
To maintain valid warranty coverage, the unit must be installed according to state and local codes, paired with a new certified coil, and registered online through the manufacturer. After purchase, a representative will contact you for installation information to help with registration.
Energy Efficiency and the FVM4X4800BL’s Variable Speed Technology
The heart of the FVM4X4800BL’s efficiency is its advanced variable-speed ECM blower motor. Unlike single-speed motors that operate at full capacity or not at all, this technology enables the blower to run at precisely the speed needed for current conditions.
Benefits of the variable-speed technology include:
- Lower energy consumption
- Reduced temperature swings
- Enhanced humidity control
- Quieter operation
- Improved air filtration (due to consistent airflow)
This intelligent operation contributes to both comfort and potential energy savings over the life of the unit.
FVM4X4800BL Sizing Considerations
While the FVM4X4800BL is rated as a 4-ton unit, it’s worth noting that in many installations, this air handler may be sized larger than the outdoor condenser it pairs with. This deliberate “oversizing” of the air handler helps maintain overall system efficiency and optimal performance.
Remember that for cooling operation, this air handler must be paired with an outdoor condensing unit – it cannot provide cooling on its own.
Frequently Asked Questions About the FVM4X4800BL
Is the FVM4X4800BL Compatible with Smart Thermostats?
Yes, the FVM4X4800BL works with most modern smart thermostats that support variable-speed systems. The unit’s control board communicates with compatible thermostats to adjust airflow dynamically.
Does the FVM4X4800BL Come with a Filter?
While the unit has a slot for a 19â…ž” × 21½” filter, filters are typically not included and must be purchased separately. This allows you to choose the filter type and MERV rating that best suits your air quality needs.
Can the FVM4X4800BL Be Used in a Zoned System?
Yes, the variable-speed capability of the FVM4X4800BL makes it ideal for zoned HVAC systems. The unit can adjust airflow to accommodate the varying demands of different zones.
