Why Choose a Goodman Cased Coil? 

Why Choose a Goodman Cased Coil? 

When you are planning a renovation or replacing an aging HVAC component, it is easy to focus on the big unit sitting outside your house. But for your system to actually cool your home, the equipment inside is just as necessary. Specifically, the cased evaporator coil is the part that absorbs heat and humidity from the air. If you are looking for durability and efficiency, a Goodman cased coil is one of the smartest upgrades you can make.

The All-Aluminum Advantage

In the past, many coils were made of copper. While copper is a good conductor, it is prone to rust and corrosion over time, which can lead to leaks. Goodman has solved this problem by using an All-Aluminum evaporator coil design. This single-metal construction is incredibly durable and designed to resist rust, ensuring your system lasts longer. Both models we carry feature foil-faced insulation on the internal casing, which helps reduce cabinet condensation and keep the system running efficiently.

A Solution for Every Size

Whether you have a small apartment or a large family home, getting the right size coil is critical for efficiency. We currently highlight two versatile options:

  • For Smaller Spaces (1.5 Ton): The CAPFA1818A6 is designed for 1.5- to 2-ton systems. It is compact, measuring just 14 inches wide and 18 inches high, making it a great fit for tighter spaces. Despite its small size, it includes a rust-resistant thermoplastic drain pan with a low-water-retention design to prevent standing water.
  • For Maximum Power (4-5 Ton): If you need to cool a larger area, the CAPF4860D6 is a powerhouse. It is designed for 4 to 5-ton systems and measures 24.5 inches wide. Like its smaller counterpart, it features a 21-inch depth for easier attic access, making it a practical choice for various home layouts.

A Note on Installation

Budget Air Supply offers wholesale prices on these coils to help you get the best equipment for your budget. However, we always recommend having a certified HVAC professional handle more complicated installs.

Replacing a coil involves specific tasks like brazing refrigerant lines and checking piston sizes (such as the .055 for the small unit or .093 for the large unit). A professional ensures your system runs safely and efficiently, protecting your investment for the long haul.

Finding the Right Supply Partner

Locating the specific replacement parts you need shouldn't be a hassle. At Budget Air Supply, we make it easier for homeowners and contractors to access a massive inventory of wholesale HVAC supply products without breaking the bank.
