2.5 Ton 15 SEER Goodman Air Conditioner with Horizontal 24.5" Cased Coil Review 2026

// Bottom Line

This horizontal A-coil works best for contractors building out budget systems or homeowners upgrading older equipment without premium pricing. At $115, the 16 SEER1 efficiency and 10-year registered warranty deliver genuine value for mid-range residential applications.

Review

This Goodman horizontal cased coil sits in the practical middle ground of the residential HVAC market. At $115, it targets contractors and DIY-minded homeowners seeking dependable performance without premium pricing. The unit carries Energy Star certification and promises reliable operation through a robust warranty structure. It's designed as a drop-in replacement for standard residential systems, making it accessible for both new installations and retrofit scenarios.

The cooling capacity hits 29,000 BTU output with a 16 SEER1 efficiency rating that qualifies as Energy Star compliant. The scroll compressor operates on 208/230V single-phase power, drawing between 17.1 and 25 amps depending on your electrical service. Dual refrigerant compatibility with R410A or R22 adds flexibility for different system setups. Operating noise sits at 71.5 dB, which you'll notice in quiet settings but remains acceptable for residential use.

Installation

Horizontal orientation suits attic installations where vertical space is limited. The unit weighs 30 pounds, manageable by two technicians. Suction and liquid lines measure 7/8 inch and 3/8 inch respectively, with 3/4 inch insulation thickness included on the suction line. Standard 208/230V single-phase service handles requirements easily on most homes. Pre-charged design and standard valve sizes minimize complexity during commissioning.

Warranty & Reliability

Coverage extends 10 years from purchase date when registered online with the manufacturer. This registration-based approach is common industry practice but requires upfront paperwork to activate full protection. The warranty covers defects in materials and workmanship, typical for coil products. No parts-and-labor coverage mentioned, so homeowners should verify what service calls actually include through their installer.

Frequently Asked Questions

Does the 2.5 ton rating actually match the 5 ton specification listed? +

Product literature shows conflicting tonnage claims. The 29,000 BTU cooling output corresponds to 2.4 tons (12,000 BTU per ton). Request clarification from Online Supply before purchase to confirm which tonnage matches your system requirements and avoid sizing errors.

Will this coil work with my existing R22 air handler? +

Yes, this unit supports both R410A and R22 refrigerant. However, verify with your technician that the coil's operating pressures match your outdoor condenser unit. Mixing refrigerant types between components creates system failures and voids warranties.

How much can I save on cooling costs compared to older equipment? +

The 16 SEER1 rating typically delivers 15-20% annual cooling cost reduction versus 10 SEER units common in homes built before 2010. Actual savings depend on local electricity rates, climate, and system runtime. Most homeowners see payback within 5-7 years.

Is this coil better than competitor brands at similar price points? +

Goodman equipment offers reliable performance with competitive pricing. This specific unit competes well against Carrier Performance and Lennox models in the budget tier. However, premium brands offer quieter operation and advanced compressor stages if you prioritize efficiency margins.

What does the 10-year warranty actually cover? +

Manufacturer covers defects in materials and workmanship for a decade with registration. Labor and service call costs typically fall to you. Review the complete warranty documentation before purchase to understand exclusions and claim procedures.
