About this system
The Goodman CHPTA2426B3 is a 2-ton horizontal evaporator coil designed to work with R-32 refrigerant systems. The horizontal orientation makes it a practical choice for attic installations or tight crawl-space air handler setups where a vertical coil simply will not fit. The internal thermal expansion valve (TXV) regulates refrigerant flow more precisely than a fixed orifice, helping maintain steady cooling performance across a range of outdoor temperatures and load conditions.
R-32 is a lower global-warming-potential refrigerant that is becoming more common as R-410A is phased down under EPA regulations. Choosing an R-32-compatible coil now positions a system for the direction the industry is heading, which matters if you are planning a full system replacement or upgrading an air handler. Because this is a coil only and not a complete system, there is no SEER2 rating attached to this part alone; the efficiency figure you see on paper will depend entirely on the matched outdoor condensing unit and air handler combination.
At 2 tons, this coil is sized for smaller homes or single zones, typically spaces in the 900 to 1,200 square foot range depending on climate, insulation, and local load calculations. It is not a plug-and-play part; proper sizing, refrigerant charge, and leak-free brazing on installation day are the factors that will determine how well and how long it performs.
The CHPTA2426B3 is a budget-accessible R-32 horizontal evaporator coil that does the job when installed correctly and matched to the right condensing unit. Goodman's value positioning means you are trading some long-term reliability margin and brand support for a lower upfront cost, and that trade-off is most visible in evaporator coil leaks that appear in a notable share of owner reports. It suits buyers who are cost-conscious, are working with a skilled installer, and are realistic about potential mid-life maintenance.
Overall score is the average of the five ratings above.
What we like
- R-32 compatibility keeps the system relevant as R-410A is phased down by EPA regulations
- Internal TXV improves part-load refrigerant control compared to fixed-orifice coils
- Horizontal configuration directly addresses attic and non-standard air handler installations where vertical coils are not an option
- Priced 15 to 25 percent below comparable Trane, Lennox, and Carrier coil options, freeing up budget for quality installation labor
- Cased design simplifies air handler integration and reduces bypass air leakage around the coil
Trade-offs
- Evaporator coil leaks are a documented and recurring complaint among Goodman owners, and this is the exact component type involved
- No standalone efficiency rating; actual system SEER2 depends entirely on the matched outdoor unit and air handler combination
- R-32 requires certified technicians with updated equipment, which can limit service options in some markets
- Goodman's ConsumerAffairs score sits around 2.5 out of 5, with repair costs after year 7 being the most common grievance
What homeowners and pros say about Goodman
Homeowners who have gone the Goodman route often point to the lower purchase price as the deciding factor, and that sentiment shows up in Google dealer reviews that cluster around 3.8 out of 5, where affordability is consistently the most praised attribute. But the picture gets more complicated over time. On ConsumerAffairs, Goodman scores closer to 2.5 out of 5, and the reviews there skew toward owners who are frustrated by repair costs climbing after roughly year seven, which aligns with the documented compressor lifespan of 10 to 14 years versus the 15 to 20 years more common in premium brands.
For a product like this evaporator coil specifically, the failure modes most worth knowing about are coil leaks and refrigerant leaks. Evaporator coil leaks appear in a meaningful share of Goodman owner reports and can be costly to address once the system is out of warranty. A smaller group of owners reports refrigerant leaks within the first year, and HVAC technicians consistently attribute those early failures to install quality rather than the equipment itself. The dual-run capacitor failures that Goodman is widely known for apply to the outdoor condensing unit rather than the coil, but they are a useful reminder that Goodman systems tend to reward owners who budget for routine maintenance and have a reliable local technician on call.

Questions about this system
Will this coil work with my existing R-410A condensing unit?
No. The CHPTA2426B3 is designed for R-32 refrigerant systems and should not be mixed with R-410A equipment. Mixing refrigerants or pairing mismatched coils and condensers can damage the compressor and void the warranty. Confirm your outdoor unit is R-32 rated before purchasing.
What causes the evaporator coil leaks I keep reading about with Goodman?
Goodman owner reviews cite evaporator coil leaks as a recurring issue, and the causes typically fall into two categories: formicary corrosion from household chemicals over time, or microcracks that develop from manufacturing tolerances. A minority of owners also report refrigerant leaks within the first year, which is more often an installation or charge issue than a defect in the coil itself.
Is a TXV really necessary at 2 tons, or is a fixed-orifice system fine?
A TXV is the better choice for most residential systems because it adjusts refrigerant flow as conditions change, maintaining efficiency over a wider range of outdoor temperatures. At 2 tons the difference is less dramatic than on larger systems, but the TXV still helps protect the compressor from flooding or starving the coil under unusual load conditions.
Can I install this coil myself to save on labor costs?
No. R-32 is classified as a mildly flammable (A2L) refrigerant, and EPA Section 608 requires certified technicians to handle, recover, and charge it. Beyond legal requirements, brazing errors and improper refrigerant charge are the leading causes of early coil and compressor failure, so professional installation is not optional if you want the warranty and the system to last.
What does Goodman's warranty actually cover on this coil, and are there conditions?
Goodman typically offers a 10-year parts warranty on registered equipment, but coverage usually requires registration within a set window after installation and proper installation by a licensed contractor. Read the warranty terms for this specific model before purchasing, because unregistered units often drop to a shorter base coverage period, and coil leaks after the warranty period are an out-of-pocket repair.
