2.5 Ton Rheem 14.3 SEER2 R-454B Two Stage Heat Pump System RP14AY30AJ2NA, RH2TY3617STANNJ
This 30,000 BTU Rheem heat pump package moves up to the RH2TY3617STANNJ air handler, a three-ton-class coil in a 17.5 inch cabinet, paired with the two-stage RP14AY30AJ2NA outdoor unit. The combination is deliberately coil-heavy: more evaporator face area with a 2.5 ton compressor produces a lower sensible heat ratio, which is exactly what a humid climate needs. Homeowners get the dehumidification benefit without giving up the narrow closet footprint.
Is a 2.5 Ton Heat Pump System the Right Size?
A 2.5 ton system covers roughly 1,100 to 1,500 square feet in most of the Sun Belt. It is a frequent answer for three-bedroom ranch homes, mid-size townhouses and 1990s-era tract houses that have had attic insulation or windows upgraded since the original system was installed.
This capacity is also where many homes sit between two nominal sizes. When a Manual J calculation lands between 24,000 and 30,000 BTU, the 2.5 ton two-stage unit is usually the safer pick, because low stage covers the lighter part of the season without the short cycling that an oversized single-stage unit produces. Verify that the existing duct system can carry the airflow before upsizing from a 2 ton.
Ideal for: Three-bedroom ranch homes, larger townhomes, renovated tract houses, and open-plan homes in the 1,100 to 1,500 square foot range.
Need more capacity? Step up to the 3 Ton Rheem RP14AY36AJ2NA, RH2TY3617STANNJ Heat Pump System, which uses the identical air handler with a larger outdoor unit.
Recommended capacity ranges are general guidelines only. Actual system requirements depend on insulation, window area, duct design, air infiltration, and local climate. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The RH2TY3617STANNJ steps the blower up to a larger constant-torque ECM motor than the 2417 cabinet uses, so it has the static pressure headroom for longer duct runs and higher-MERV filtration. Mount the outdoor unit on a 40 x 40 Cladlite hurricane condenser pad to keep it level and above standing water.

Frequently Asked Questions
Is 2.5 tons enough for a 1,400 square foot house?
In most cases yes, provided the attic is reasonably insulated and the ductwork is sealed. Homes with heavy west-facing glass, cathedral ceilings or leaky ducts may calculate closer to 3 tons, so run the load before deciding.
Why does this system use the RH2TY3617STANNJ instead of the 2417 cabinet?
The 3617 is the next coil size up and is rated for 2.5 to 3 tons. Rheem matches it to the 30,000 BTU condenser so the evaporator is generously sized, which lowers coil temperature and pulls more humidity out of the supply air.
What electrical service does the RP14AY30AJ2NA need?
208/230V single phase, 60 Hz, with a 20 amp minimum circuit ampacity and 30 amp maximum overcurrent protection. The air handler and any electric heat kit require a separate circuit sized to the kit.
Does the larger coil really improve dehumidification?
Yes. A bigger evaporator paired with a smaller compressor lowers the sensible heat ratio, meaning a larger share of the system's work goes into removing moisture instead of dropping air temperature. Combined with low-stage run time, it keeps indoor relative humidity down.
Can the air handler be installed horizontally in an attic?
Yes. The RH2TY3617STANNJ converts to horizontal left or horizontal right in the field. Attic installations require an auxiliary drain pan with a float switch and adequate service access per local code and the installation instructions.
How does the RP14AY compare with the RP15AY at this capacity?
The RP15AY is the next efficiency tier in Rheem's Endeavor Line and carries a higher SEER2 rating with a larger outdoor coil and footprint. The two share a common installation manual, so the differences are easy to compare side by side. Browse all Rheem heating and cooling equipment to weigh the tiers.
