About this system
The Goodman CHPTA1822A3 is a 1.5-ton horizontal evaporator coil designed for tight installations where a vertical coil simply will not fit, such as attic air handlers, closet systems, and crawlspace setups. It uses R-32 refrigerant, a lower-global-warming-potential alternative to the older R-410A that is becoming the new standard across residential HVAC equipment. The internal thermostatic expansion valve (TXV) is a meaningful upgrade over fixed-orifice metering devices, providing more precise refrigerant flow control across a wider range of outdoor conditions and load variations.
This is a replacement or new-installation coil, not a complete system, so it must be matched with a compatible Goodman or Daikin air handler and a condenser unit rated for R-32. At 1.5 tons, it is sized for smaller homes, conditioned spaces in the 600 to 900 square foot range depending on climate and insulation, or zone additions. The horizontal configuration adds installation complexity compared to a standard vertical coil, and the R-32 refrigerant requires that the technician use equipment and certification specific to A2L refrigerants. Buyers should confirm their installer is current on A2L handling before scheduling the job.
The CHPTA1822A3 is a competitively priced horizontal evaporator coil that delivers reliable baseline performance when properly matched and installed by a technician experienced with R-32 and horizontal configurations. The internal TXV and R-32 refrigerant are genuine spec-level advantages at this price point. However, Goodman's documented history of evaporator coil leaks in owner reviews means installation quality and refrigerant charge accuracy are not optional considerations here — they are the difference between a decade of trouble-free cooling and an early warranty call.
Overall score is the average of the five ratings above.
What we like
- Priced 15 to 25 percent below comparable Carrier, Trane, and Lennox coils
- Internal TXV included from the factory, improving efficiency and reducing install variables
- R-32 refrigerant aligns with the industry's regulatory direction, avoiding near-term refrigerant availability concerns
- Horizontal orientation opens up installation locations that vertical coils cannot accommodate
- Wide compatibility within the Goodman and Daikin product ecosystem
Trade-offs
- Goodman's documented evaporator coil leak rate in owner reviews is a legitimate concern for this coil type specifically
- R-32 is an A2L mildly flammable refrigerant, requiring technicians with current A2L certification and appropriate equipment
- Horizontal coils are more complex to install and access for service than vertical counterparts, raising labor costs over the system's life
- No SEER2 rating applies to the coil alone, so system efficiency depends entirely on the matched condenser and air handler combination
What homeowners and pros say about Goodman
Homeowners who have replaced aging R-410A coils with Goodman R-32 equipment generally lead with cost as the deciding factor, and that holds for this coil as well. Goodman earns a Google dealer review average of around 3.8 out of 5, where affordability is the praise that comes up most often. On ConsumerAffairs, the picture is less comfortable: the brand sits at roughly 2.5 out of 5, a channel where dissatisfied owners are more likely to post, and the recurring pattern in those complaints is repair costs accelerating after about year seven. For a coil, that timeline matters because evaporator coil leaks are one of the named failure modes appearing across Goodman owner feedback, meaning the coil itself is not immune to the quality concerns that follow the brand.
HVAC technicians tend to frame Goodman equipment, including its coils, as installation-dependent hardware. The internal TXV on this unit is a positive because it removes one field-installation variable, but techs consistently note that R-32 system startups require correct charge weight, leak-free connections, and A2L-compliant tools — corners that get cut with budget jobs are the ones that turn into warranty calls. Capacitor failures are the most frequently cited Goodman repair across the broader lineup, typically a straightforward 300 to 600 dollar fix, and while that applies more to the condenser side, it reflects the brand’s general maintenance profile. For buyers who vet their installer as carefully as they vet the equipment price, this coil represents a reasonable value in the R-32 transition era.

Questions about this system
Can this coil be used with my existing R-410A condenser?
No. The CHPTA1822A3 is designed for R-32 refrigerant and is not compatible with R-410A equipment. Mixing refrigerant types or using mismatched components will void the warranty, risk equipment damage, and is a code violation. You will need an R-32-rated condenser and air handler to build a compliant system.
Does my installer need special certification to work with R-32?
Yes. R-32 is classified as an A2L mildly flammable refrigerant, which requires technicians to use A2L-rated tools and follow updated safety protocols. Confirm your contractor has current A2L training before scheduling the installation, as not all technicians have updated their certification yet.
What warranty does this coil carry?
Goodman typically offers a 10-year parts warranty on registered residential equipment, including evaporator coils, provided the unit is registered within a set window after installation and installed by a licensed contractor. Unregistered units generally fall back to a shorter limited warranty, so registration is worth completing promptly.
Goodman's reviews mention evaporator coil leaks. How worried should I be with this specific coil?
Evaporator coil leaks are one of the documented failure modes that appear in a meaningful share of Goodman owner reviews, so it is a fair concern. Proper installation, correct refrigerant charge, and avoiding mechanical stress to the coil connections during install are the most effective risk-reduction steps. Having the system leak-checked at startup is worthwhile.
Is a 1.5-ton coil the right size for my home?
Coil sizing should be based on a Manual J load calculation for your specific space, not square footage rules of thumb alone. For most climates, 1.5 tons is appropriate for roughly 600 to 900 conditioned square feet, but insulation quality, ceiling height, window area, and local climate all shift that range. Oversizing causes short-cycling and humidity problems, so confirm sizing with your installer before purchasing.
