Complete Guide to the CHPF3642C6 Evaporator Coil: Performance, Installation & Compatibility
Looking for a reliable horizontal evaporator coil for your HVAC system? The Goodman CHPF3642C6 might be exactly what you need. This 3 to 3.5-ton horizontal cased evaporator coil delivers exceptional performance in a compact package designed specifically for side installations.
What Makes the Goodman CHPF3642C6 Stand Out?
Let’s be real—most homeowners don’t get excited about evaporator coils. But when your AC stops cooling or you’re planning a system upgrade, suddenly these components matter a lot. The Goodman CHPF3642C6 is built for horizontal applications, making it perfect for installations in tight spaces like attics and crawl spaces where vertical orientation isn’t possible.
The coil features exceptional flexibility, working with both heat pumps and AC-only condensers. Plus, it’s compatible with both R410A and R22 refrigerants—though R410A is more common in newer systems as R22 has been phased out due to environmental regulations.

Why Choose the CHPF3642C6 for Your HVAC System?
When shopping for evaporator coils, there’s a lot of technical jargon thrown around. Let me break down why the CHPF3642C6 might be the right choice for your home:
Perfect Size for Most Homes
At 3 to 3.5 tons, this coil is sized appropriately for most average homes. It’s important to note that in many HVAC setups, the evaporator coil is intentionally larger than the condenser it’s paired with. This sizing difference actually helps maintain the system’s overall efficiency, so don’t worry if your condenser is smaller than 3.5 tons.
Designed for Horizontal Installations
The CHPF3642C6 is specifically engineered for horizontal installation—meaning it sits on its side. This makes it ideal for homes where space constraints don’t allow for traditional upright coil placement. Many attic and crawlspace installations require this horizontal configuration.
Built for Durability and Easy Maintenance
Goodman designed this coil with longevity in mind. It features a durable outer casing and rust-resistant drain pan to minimize wear and tear over time. For maintenance purposes, the unit includes a convenient split-seam on the front, allowing technicians easier access when service is needed.
Installation Considerations for the CHPF3642C6
Before purchasing the Goodman CHPF3642C6, there are some important installation factors to consider:
System Compatibility Requirements
This evaporator coil doesn’t work alone. You’ll need a compatible furnace or air handler to provide airflow, plus a matching outdoor condenser unit. These components are sold separately, so make sure your existing equipment is compatible or be prepared to purchase matching components.
It’s worth emphasizing that this coil is not designed to replace a coil inside a packaged air handler. It’s specifically for split-system applications where the components are separate.
Space and Accessibility
With its slim profile (21″ height), the CHPF3642C6 is designed to fit in tight spaces. The unit includes foil-face insulation that minimizes air leakage, meaning you don’t necessarily need to install it in a fully insulated space for normal operation.
However, proper clearance for maintenance access is still important. Make sure your installation location allows for future service needs.
Professional Installation Recommended
While some homeowners have DIY experience, HVAC installation typically requires professional expertise. Proper installation impacts everything from system efficiency to warranty validity. Speaking of which…
Understanding the CHPF3642C6 Warranty Coverage
Goodman stands behind their products with solid warranty protection. The CHPF3642C6 comes with a 10-year parts warranty, but there are important conditions:
- The system must be installed following state and local codes
- The coil must be paired with a compatible R410A condenser
- The entire system must be registered online through Goodman within 60 days of installation
Missing any of these steps could result in reduced warranty coverage, so make sure your installer completes the registration process.
Common Questions About the CHPF3642C6
Is the CHPF3642C6 compatible with all Goodman condensers?
While the CHPF3642C6 works with many Goodman condensers in the 3 to 3.5-ton range, it’s always best to verify specific compatibility. The coil is designed to work with both heat pumps and AC-only condensers of appropriate size.
Can I install the CHPF3642C6 in a vertical position?
No. This model is specifically designed for horizontal installation only. If you need a vertical coil, you should look at other models in Goodman’s lineup that are designed for upflow or downflow applications.
Does the CHPF3642C6 come with a TXV valve?
This model comes with a check flowrater expansion device that makes it versatile for different applications. Depending on your specific system requirements, you may need to use the appropriate orifice for your tonnage.
What maintenance does the CHPF3642C6 require?
Regular maintenance includes checking for proper drainage, cleaning or replacing the air filter in your connected air handler, and occasionally cleaning the coil itself if it gets dirty. The split-seam design makes maintenance access easier than some competing models.
Making the Right Decision for Your HVAC Needs
The Goodman CHPF3642C6 offers an excellent balance of performance, durability, and value. At $114.99, it’s an affordable option for homeowners looking for quality without breaking the bank.

Before making your purchase, confirm your installation requirements, measure your available space, and verify compatibility with your existing or planned system components.
