Is a 2.5 Ton Straight Cool Package Unit the Right Size?
The half-ton step is about matching the load closely. If your home's cooling load is about 27,000 to 30,000 BTUh, a 2 ton unit will run nonstop on the hottest days, while a 3 ton may cycle too quickly to control humidity. The WPA530A000RKB adds 5,600 BTUh of rated cooling and 200 CFM over the 2 ton model.
Window orientation, attic insulation, duct leakage, and occupancy all shift where your home lands. For heat, size the optional electric heater to your climate. A 5 kW heater covers mild winters, while 10 or 15 kW suits cooler regions. Each heater requires at least 1,000 CFM of airflow on this size.
Ideal for: Mid-size single-family homes, double-wide manufactured homes, small retail shops, and professional offices with 2.5 ton cooling loads.
Need more capacity? Step up to the 3 Ton EcoTemp Straight Cool Package Unit WPA536A000RKB for an additional half ton of cooling.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, ductwork, climate, window area, occupancy, and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
How does the 2.5 ton WPA530A000RKB compare with the 2 ton WPA5?
Rated cooling rises from 23,200 to 28,800 BTUh and airflow from 750 to 950 CFM. It also accepts up to a 15 kW heater instead of 10 kW. Electrical increases to 20.6 MCA with a 30 amp maximum breaker without a heater.
Can the WPA530A000RKB use a 15 kW electric heater?
Yes. The manufacturer lists a 15 kW heater (CPHEATER133) for sizes 30–36. With it installed, the MCA is 72.6/83 amps at 208/230V, and the maximum overcurrent protection is 80/90 amps.
What breaker does the 2.5 ton WPA5 need without a heater?
Without electric heat, use a maximum 30 amp fuse or HACR breaker, with wiring sized for a minimum circuit ampacity of 20.6 amps on 208/230V single-phase power.
Which roof curb or adapter fits the WPA530A000RKB?
The CPRFCURB011B00 14-inch roof curb fits sizes 24–30. When replacing an older unit, the CPADCURB001A00 adapter curb works with existing NPRFCURB006A00/007A00 curbs and with older composite-base units that lack metal rails.
Which economizers are available for the 2.5 ton WPA5?
Sizes 24–30 use the CPECOMZR007B00 dedicated vertical economizer or the CPECOMZR010A00 horizontal economizer. Both include a filter rack with 1-inch filters.
What airflow does a heater require on the WPA530A000RKB?
The manufacturer requires at least 1,000 CFM for safe electric heater operation on size 30.
