About the H-401

Where the H-401 fits

An evaporator coil is the indoor half of a split air-conditioning or heat-pump system. Refrigerant expands inside it and absorbs heat from the air the blower pushes across the fins, which is what actually cools and dehumidifies the house. The H-401 only performs as rated when it is paired with an outdoor unit of matching capacity and the same refrigerant, and when its cabinet physically fits the furnace or air handler it sits on. A mismatched coil is the most common reason a new system tests below its nameplate efficiency.

Coil construction matters too: aluminum-fin, aluminum-tube designs resist the formicary corrosion that used to eat copper coils in a decade, and a cased coil arrives with the drain pan, access panel and cabinet already built so it sets straight onto the furnace. Uncased coils are for retrofits into an existing plenum.

What to check before you order

• Tonnage: match the outdoor unit (a coil one size up is sometimes specified by AHRI, never one size down).
• Refrigerant: R-32 coils pair only with R-32 outdoor units; R-410A with R-410A.
• Cabinet width and orientation: upflow/downflow versus horizontal, and the cabinet letter (A/B/C/D) has to match the furnace or air handler width.
• Metering device: TXV or EEV as specified for the outdoor unit you are pairing it with.
• AHRI match: look the combination up before you order so the rating and any rebate paperwork line up.

Installation and service notes

Set the coil level on the furnace or air handler with the drain pan sloped to the primary drain, and seal the cabinet-to-coil joint so return air cannot bypass the fins. Braze with nitrogen flowing, pull a deep vacuum, and weigh in the refrigerant charge to the outdoor unit’s chart rather than guessing from pressures. A float switch in the secondary pan is cheap insurance against a clogged drain.
