About this system
The Goodman CHPTA1822B3 is a 1.5-ton horizontal evaporator coil built for R-32 refrigerant and designed to work with a matched outdoor condensing unit in a split-system configuration. The horizontal orientation makes it a practical choice for attic installations, crawl-space air handlers, or any application where a vertical coil simply will not fit. The internal TXV (thermostatic expansion valve) is a meaningful inclusion at this price point: it meters refrigerant flow based on actual system demand rather than relying on a fixed orifice, which supports more consistent performance across varying load conditions and is required by some equipment manufacturers to maintain warranty coverage.
R-32 refrigerant is a lower-global-warming-potential alternative to the R-410A that dominated residential HVAC for two decades. It carries a GWP of 675, roughly one-third that of R-410A, and is increasingly the refrigerant of choice as the industry phases down high-GWP options under updated EPA regulations. For homeowners and contractors planning new installs or system replacements, pairing R-32 components now means the system is positioned for the regulatory direction the industry is moving. One practical note: R-32 is mildly flammable (classified A2L), so installation must follow current safety codes, and not every technician is yet equally familiar with handling it. Confirming your contractor has R-32 experience before the job starts is worth doing.
At 1.5 tons, this coil is sized for smaller conditioned spaces, typically homes or zones in the 600 to 900 square foot range depending on climate, insulation quality, and internal load. It is a replacement or new-install component, not a standalone system, and its final performance will always reflect the quality of the matched equipment and the care taken during installation.
The CHPTA1822B3 is a competitively priced horizontal evaporator coil that gets the fundamentals right for budget-conscious installs: the included TXV is a genuine value-add, and R-32 compatibility keeps the system relevant as refrigerant regulations tighten. The trade-offs are the ones that follow Goodman across its product line: coil leak complaints appear in owner reviews at a rate that warrants attention, and long-term durability depends heavily on who installs it and how carefully.
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, supporting more stable refrigerant metering without an add-on cost
- Horizontal layout fills a real need for attic and tight-clearance installations
- R-32 refrigerant compatibility aligns with current regulatory direction
- Cased construction simplifies installation compared to uncased alternatives
Trade-offs
- Evaporator coil leaks are a documented failure mode in owner reviews, which can be a costly repair outside warranty
- A minority of owners have reported refrigerant issues within the first year, typically linked to installation or charge problems rather than the coil itself
- R-32 is an A2L mildly flammable refrigerant, requiring confirmed contractor familiarity and code-compliant handling
- Long-term reliability tracks below premium brands, with compressors in matched systems averaging 10 to 14 years versus 15 to 20 for Trane or Lennox
What homeowners and pros say about Goodman
Goodman sits at roughly a 2.5 out of 5 on ConsumerAffairs, a platform that skews heavily toward complaint-driven feedback, and around 3.8 out of 5 across Google dealer reviews where affordability is consistently the most common reason owners say they chose the brand. For an evaporator coil like the CHPTA1822B3, those numbers reflect a familiar pattern: buyers who go in with realistic expectations about a value-tier product and have it installed by a careful technician tend to come away satisfied, while those who encounter problems often find repair costs climbing, particularly after year seven when components are no longer under warranty.
The failure modes most commonly associated with Goodman across its product line are relevant here. Evaporator coil leaks appear in a meaningful share of owner reviews and are one of the more expensive problems to address when they occur. Refrigerant issues within the first year show up in a minority of reports, and these typically trace back to installation or charge problems rather than a defect in the coil itself, which underscores how much the outcome depends on the contractor doing the work. Dual-run capacitor failures are the most frequently reported issue in matched Goodman systems overall, but those are a condensing unit concern rather than a coil concern. For the CHPTA1822B3 specifically, the coil leak history is the detail worth factoring into the decision, especially for buyers choosing between this and a Carrier or Trane coil with a longer documented reliability record.

Questions about this system
Does this coil work with any R-32 condensing unit, or does it have to be a Goodman unit?
Goodman strongly recommends and in many cases requires matched Goodman or Daikin equipment to maintain warranty coverage, since the two brands share a parent company and certified matched-system pairings. Using this coil with a non-Goodman condensing unit may void the warranty and can introduce compatibility issues with refrigerant charge and system sizing. Check Goodman's published match-up tables or confirm with your distributor before mixing brands.
Is R-32 safe to have in my home, and does my contractor need special certification to work with it?
R-32 is classified A2L, meaning it is mildly flammable but has a very high ignition threshold that makes it safe for residential use when installed and serviced per current codes. Your contractor does not need a separate certification beyond EPA Section 608 in most jurisdictions, but they do need practical familiarity with A2L handling procedures. Asking your technician directly about their R-32 experience before the job is a reasonable step.
What warranty does Goodman provide on this coil, and is registration required?
Goodman typically offers a 10-year parts limited warranty on registered systems, dropping to a shorter coverage period if the product is not registered within the required window after installation. Registration is the owner's responsibility, not the contractor's, so confirming the deadline and completing it promptly matters. Review the current warranty document on Goodman's site for this specific model number since terms can vary.
Evaporator coil leaks come up in Goodman reviews. How serious is that risk, and what does it cost to fix?
Coil leaks are one of the documented failure modes in Goodman owner reviews, though they are not universal. A confirmed coil leak typically requires either a repair or a full coil replacement, which can run into several hundred to over a thousand dollars depending on labor, refrigerant recovery, and recharge costs. If the coil is still under warranty, the part itself may be covered, but labor is typically not, which is where the real expense sits.
This is a horizontal coil. Can it be converted to vertical if I change my setup later?
The CHPTA1822B3 is built specifically for horizontal orientation and is not designed for conversion to vertical use. If your installation needs change or you end up needing a vertical configuration, you would need a different coil model. Planning the correct orientation before purchase avoids a costly swap later.
