1.5 - 2 Ton
These factory-cased indoor coils are sized for 18,000-24,000 BTU systems and built to pair with today’s condensers and heat pumps. Choose the airflow you need-Horizontal, Vertical, or Multi-Position-and the cabinet footprint that fits: 14", 17.5", or 21". Designed to support SEER2-rated system matches when paired correctly, they’re a smart upgrade or direct replacement during changeouts.
Whether you’re a homeowner, DIY-capable buyer, licensed contractor, or property manager, this lineup covers common install scenarios: replace or match an indoor coil, pair with a 1.5 or 2 ton outdoor unit, and support specific refrigerants (R-32, R-410A, R-454B). Verify the metering device (TXV or piston) and orientation to ensure proper airflow and capacity with your furnace or air handler.
We stock budget-friendly options with fast availability, typically ranging from $665 to $1177. For A2L refrigerants like R-32 and R-454B, use approved components and follow code. Professional installation is required in most areas to protect performance, safety, and warranty.

Frequently Asked Questions
-
How do I choose the right cased coil size for a 1.5-2 ton outdoor unit?
Match the coil’s nominal tonnage (1.5 or 2 ton) to the condenser and verify an AHRI-listed match, metering device, and airflow.
-
Which refrigerant coil (R-32, R-410A, or R-454B) should I use for my system?
Use the same refrigerant as the outdoor unit. R-32 and R-454B are A2L; follow approved components and local codes.
-
What cabinet width (14", 17.5", or 21") fits my existing furnace or air handler?
Measure the furnace or air handler cabinet. Choose the matching width; transition kits can adapt when sizes differ.
-
Should I select horizontal, vertical, or multi-position for my installation?
Match the coil orientation to your ductwork and space. Multi-position adds flexibility-follow the drain pan orientation.
-
Are these cased coils compatible with both air conditioners and heat pumps?
Yes. Confirm the correct TXV/piston for your refrigerant and use heat-pump-rated components where required.
-
Do I need a licensed contractor to replace a cased evaporator coil?
In most jurisdictions, yes. Refrigerant handling, charging, and A2L rules require certified professional installation.
-
Can I use a 1.5-2 ton coil with a 1.5 or 2 ton condenser without performance loss?
Yes, when properly matched and charged, with correct metering device and 350-450 CFM per ton airflow.
-
What additional parts (TXV, line set flush) are needed when switching refrigerants?
Typically a new TXV/piston for the refrigerant, a new filter drier, nitrogen purge, deep vacuum, and cleaned or replaced lines.
-
How do SEER2 systems affect coil selection?
SEER2 is a system rating. Pick coils listed in AHRI matches for your outdoor unit to meet efficiency targets.
-
What maintenance helps my new coil last?
Replace filters regularly, keep the drain clear, maintain airflow, and schedule annual professional service.
