2.5 Ton EcoTemp 14.5 SEER2 R-454B Heat Pump System – W5H5S30AKAAA & WCHL305AB
At 70 dBA, the W5H5S30AKAAA is the quietest outdoor unit in the EcoTemp W5H5S heat pump series. Paired with the WCHL305AB A-coil air handler, it delivers 30,000 BTU/h of R-454B heating and cooling at 14.5 SEER2. This 2.5 ton system is a strong fit for mid-size homes where the outdoor unit sits near a patio, bedroom window or neighbor's property line.
Is a 2.5 Ton Heat Pump System the Right Size?
A 2.5 ton system fills the gap between smaller 2 ton applications and full 3 ton homes, covering loads around 30,000 BTU/h. Choosing a half-ton size when the load calls for it helps avoid an oversized system that short-cycles. Estimate with our AC tonnage calculator, then confirm with a Manual J.
Check that ductwork can deliver about 875 CFM, the WCHL305AB's nominal airflow. To keep condensate in the drain pan, the spec sheet calls for return static pressure below 0.40" w.c. Backup heat strips are offered in 5, 8 and 10 kW.
Ideal for: Mid-size homes, ranch and split-level houses, homes where outdoor unit noise matters, and replacements of existing 2.5 ton heat pumps.
Need more capacity? Step up to the 3 Ton EcoTemp W5H5S36AKAAA & WCHL365AB Heat Pump System for homes requiring additional heating and cooling capacity.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, climate, duct design, window load, occupancy and desired indoor temperature. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The 2.5 ton size is where the W5H5S line moves to a 3/4" vapor valve and rated 3/4" vapor line, which matches the 3/4" x 3/8" line sets offered with this system. The outdoor unit is 38-7/16" tall on a 31-3/16" square base, weighs 167 lbs and holds 6.1 lbs of R-454B. Indoors, the WCHL305AB is the smallest WCHL with an A-coil. It measures 49-5/8" H x 17-5/8" W and is driven by a 1/2 HP multi-tap ECM motor. Also available separately: the W5H5S30AKAAA heat pump and WCHL305AB air handler.

Frequently Asked Questions
How quiet is the W5H5S30AKAAA outdoor unit?
It has a 70 dBA sound power rating, the lowest in the W5H5S heat pump series. With the accessory sound shield, the rating drops to 67 dBA.
What type of coil is in the WCHL305AB?
The WCHL305AB uses an A-coil. For horizontal A-coil installs, the NAMA00125HC horizontal water management kit is listed as an accessory.
Can my existing ductwork handle the 2.5 ton system?
The WCHL305AB is rated at 875 CFM nominal. Ducts should allow that airflow while keeping return static below 0.40" w.c., which helps prevent condensate from blowing out of the drain pan.
What electrical service does the 2.5 ton system require?
The W5H5S30AKAAA needs 16.3 MCA and a 25 amp max breaker. Without electric heat, the WCHL305AB needs 5.3 MCA on a 15 amp circuit. A heat strip increases the air handler's requirement.
How long can the refrigerant line set be?
The W5H5S allows up to 200 ft actual and 250 ft equivalent length. Runs beyond 80 ft on the same level are long-line applications and require additional accessories.
Does this system work with smart thermostats?
The system supports both programmable and standard thermostat controls. Several programmable and Wi-Fi heat pump thermostats are offered as add-ons with this listing.
