SHORT DESCRIPTION

Advantage 5th Gen 18k BTU 230V Condenser

LONG DESCRIPTION

The 5th Generation 18k BTU 230V Advantage condenser is the right choice for anyone who needs fast, efficient, and effective home comfort. While this ductless mini-split unit must be installed by an HVAC professional, it’ll be a much cheaper and faster process than a typical installation of a central system, as it is a ductless mini-split unit. It’ll also be worth it because this system is incredibly convenient and user-friendly, thanks to features like its Wi-Fi Module! This feature enables integration with your phone and allows you to use Amazon Alexa and Google Assistant, which lets you literally speak your comfort into existence. When it comes to its operation, this system uses significantly less energy than its previous generation because it uses R-454B instead of R-410A. R-454B has around 80% less of a GWP (global warming potential), which allows the system to be much more eco-friendly, reducing your carbon footprint while you enjoy perfect comfort. Use of this refrigerant also enhances the efficiency of this system, so this condenser can achieve up to a 19.2 SEER2 rating and a 9.3 HSPF2-4 rating. This system is perfect for a space that is up to and around 800 square feet. We’ve got your back when it comes to this unit, too. Once you register, you are entitled to a 2 year parts warranty and a 1 year compressor warranty on this unit. Let the 5th Generation 18k BTU Advantage condenser give you the comfort you deserve at the price point you want.

    Product FAQs

    Product FAQs

    Helpful answers matched to this product, brand, specs, and configuration.
    Where should I purchase MRCOOL equipment?

    MRCOOL products are sold through authorized retailers and distributors rather than directly by MRCOOL to consumers. Purchasing through an authorized seller helps confirm that the equipment is genuine and that the correct purchase records are available for product and warranty support.

    Can MRCOOL components from different series, generations, or refrigerant platforms be mixed?

    Do not assume that MRCOOL indoor units, outdoor units, line sets, controls, or accessories are interchangeable. Use only manufacturer-approved combinations for the exact model family; in particular, MRCOOL states that R-410A products are not compatible with R-454B products and the refrigerants must never be mixed.

    What makes an eligible MRCOOL DIY system different from a conventional mini-split?

    Eligible MRCOOL DIY systems are designed around installation-friendly components such as factory-precharged line sets and compatible connection hardware. The included components vary by generation and package, and electrical work, permits, clearances, and local code requirements still need to be followed.

    Does MRCOOL send technicians to a home or jobsite?

    MRCOOL does not dispatch field technicians. Its in-house team provides phone and email assistance for diagnosis, troubleshooting, and product guidance, while the owner arranges and pays for any local on-site technician unless a specific written warranty program states otherwise.

    Why do I need the exact MRCOOL model and serial number?

    The model and serial number identify the exact equipment, generation, capacity, and applicable documentation or warranty. Use the identification labels on the equipment and MRCOOL’s registration guidance rather than relying only on a product title or general series name.

    Are all MRCOOL systems designed for do-it-yourself installation?

    No. Only product families specifically identified by MRCOOL as DIY-capable should be treated as do-it-yourself systems. Other lines, including the Advantage Series, require professional HVAC installation, so always follow the installation requirements for the exact model.

    Where can I find MRCOOL manuals, specifications, certifications, and installation documents?

    MRCOOL maintains a documentation library and a product support center with model-specific installation manuals, owner manuals, technical documents, certifications, warranty information, and troubleshooting resources. Search using the exact model number because documents can differ by series, generation, capacity, and refrigerant.

    What types of products does MRCOOL offer?

    MRCOOL offers a broad range of comfort products, including ductless mini-splits, central ducted split systems, packaged heat pumps, geothermal systems, water heaters, fans, thermostats, line sets, and HVAC accessories. Available capacities, refrigerants, efficiencies, and features depend on the exact product family and model.

    When should an MRCOOL system be registered?

    Register the system as soon as possible after purchase and installation. Several MRCOOL residential warranty programs require registration within 60 days of installation, or within 60 days of purchase when the installation date cannot be verified, but the exact requirement is controlled by the warranty document for the specific product.

    Where can I purchase replacement parts for an MRCOOL system?

    MRCOOL recommends starting with the original place of purchase because many dealers can special-order replacement parts. If that is not available, use an authorized MRCOOL parts distributor and confirm compatibility with the exact model and serial number before ordering.

    How can I contact MRCOOL customer or technical support?

    MRCOOL provides support by phone at (270) 366-0457, by email at support@mrcool.com, and through its online support-request form. Have the exact model and serial number available so the support team can identify the correct product documentation and next steps.

    Can MRCOOL support work with my local HVAC technician?

    Yes. If a local technician is scheduled, MRCOOL’s in-house support team can help coordinate troubleshooting and product guidance with that technician. The technician should have the model, serial number, system configuration, measurements, error codes, and a clear description of the issue available.

    Where can I find MRCOOL troubleshooting and error-code information?

    MRCOOL’s support center provides separate technical-support sections for ductless systems, residential ducted systems, product-specific error codes, wiring guidance, installation procedures, and troubleshooting articles. Use the exact series and model because codes and procedures are not universal across all MRCOOL equipment.

    How do I register an MRCOOL product for warranty coverage?

    Register the product through MRCOOL’s online warranty-registration page. Be prepared to provide the serial number along with purchase, owner, installation-location, and installer information requested by the registration form.

    Does every MRCOOL product have the same warranty?

    No. MRCOOL publishes separate warranty terms for different product families, generations, and applications. For example, the current DIY 5th Generation warranty lists 5-year parts and 7-year compressor coverage, but that coverage should not be assumed for another MRCOOL series; always check the exact product warranty document.
