ADP Parts - Furnace & Unit Heaters

ADP Parts cover replacement components for Advanced Distributor Products' evaporator coils, air handlers, and unit heaters, equipment ADP has manufactured at its Grenada, Mississippi factory since 1992. ADP's coil lineup spans multi-position, horizontal, downflow, plenum, and manufactured-home configurations, while its air handler series range from low-profile and compact wall-mount models to modular blower and soffit-mount designs, so parts orders need to identify the specific series and model before pulling a component. Coils built with ADP's Microban antimicrobial coil protection and FlexCoil metering for multiple refrigerants use parts specific to those features, which don't always cross over to older or standard coil models. Confirming series letter and model number on the equipment nameplate narrows an ADP Parts search to the right component the first time.

Subcategories

• Evaporator Coil Parts: ADP manufactures seven evaporator coil series, including the HE multi-position, HD horizontal side-connection, HH horizontal slab, V horizontal top-connection, Downflow, PL plenum, and M manufactured-home coils, each with its own cabinet dimensions and connection points. Many ADP coils use Microban antimicrobial coil protection and FlexCoil metering designed to run with multiple refrigerants, features that affect which replacement metering device or coil assembly fits a given unit. A technician needs the coil series letter and model number from the equipment nameplate before ordering a replacement coil or metering component, since cabinet and connection styles differ across the seven series. Getting the series wrong on an evaporator coil parts order usually means a return trip, since coils are not interchangeable across series.
• Air Handler Parts: ADP's air handler lineup includes the F Series low-profile, B Series multi-position and hydronic, MX Series modular blower, S Series compact wall-mount, and CP Series soffit-mount models, along with the Moduleflex eFurnace and mFurnace gas and electric furnace replacements. Hydronic-capable B Series units use hot water heat components that don't appear on standard electric air handlers, so a parts order needs to confirm whether the installed unit has a hydronic coil option. Blower assemblies, heater kits, and control boards vary by series and cabinet size, so matching the model number on the air handler's data plate is the starting point for any ADP air handler parts order. Multi-family and manufactured-home installations often use the more compact S Series or mFurnace models, which use different components than the standard F or B Series.
• Unit Heater Parts: ADP's unit heaters split into the UHRS Series for residential and light commercial use, the UHCM Series for commercial applications, and the UHSC Series for separated combustion installations where combustion air is drawn from outside rather than the mechanical room. Separated combustion UHSC units use dedicated intake and venting components that don't apply to UHRS or UHCM models, so confirming which series is installed matters before ordering venting or combustion parts. Heat exchangers, burners, and blower assemblies are sized to each series' BTU range, so a model number from the unit's nameplate is needed to pull the correct replacement. Commercial UHCM installations typically see heavier duty cycles than residential UHRS units, which affects how often heat exchanger and igniter parts turn over.

Buying Guide

ADP Parts orders start with identifying which of ADP's three equipment categories, evaporator coils, air handlers, or unit heaters, the failed component belongs to, since parts don't cross over between them. Within evaporator coils, the series letter matters: HE, HD, HH, V, Downflow, PL, and M coils use different cabinet dimensions and connection points, so a coil or metering device from one series won't fit another even at a matching tonnage. Coils built with Microban antimicrobial protection or FlexCoil multi-refrigerant metering use components specific to those features, which is worth checking against the nameplate before ordering a metering device. Air handler parts follow a similar pattern: F Series, B Series, MX Series, S Series, and CP Series units use different blower assemblies, cabinet parts, and heater kits, and hydronic-capable B Series models add hot water coil components that standard electric units don't have. Unit heater parts split further by combustion type, since UHSC separated combustion models use dedicated intake and venting parts that UHRS and UHCM models don't use. Across all three ADP Parts categories, the model number on the equipment's data plate is the fastest way to confirm series, cabinet size, and configuration before placing an order, since visual similarity between series doesn't mean a part will fit.

Frequently Asked Questions

Do ADP evaporator coils use the same parts across all coil series?

No. ADP's seven coil series, including the HE multi-position, HD horizontal, HH horizontal slab, V horizontal top-connection, Downflow, PL plenum, and M manufactured-home coils, use different cabinet dimensions and connection points. A replacement coil or metering device from one series does not fit another, so confirming the series letter from the nameplate is the first step.

What does FlexCoil metering mean for parts selection?

FlexCoil is ADP's metering design built to run with multiple refrigerants, and coils using it require metering components matched to that design rather than a generic thermal expansion valve. Checking the coil's model number confirms whether it uses FlexCoil metering before ordering a replacement device.

Are ADP air handler parts interchangeable between the F Series and B Series?

No. The F Series is a low-profile design while the B Series supports multi-position mounting and an optional hydronic hot water coil, so blower assemblies and heater kits differ between the two. Hydronic B Series units also use hot water coil components that F Series electric-only units don't have.

What's the difference between ADP's UHRS, UHCM, and UHSC unit heaters?

UHRS is built for residential and light commercial use, UHCM targets heavier commercial applications, and UHSC uses separated combustion, drawing combustion air from outside rather than the mechanical room. UHSC units need dedicated intake and venting parts that the other two series don't use.

How do I identify the correct ADP part for a coil, air handler, or unit heater?

The model number on the equipment's data plate identifies the series, cabinet size, and configuration needed to match a replacement part. Since ADP's coil, air handler, and unit heater series aren't interchangeable, ordering by visual similarity instead of model number is the most common cause of a wrong part.
