MRCOOL 15kW Heat Kit for Central Ducted VersaPro® 2nd Gen Air Handler, MVPHK15

The main difference between the MRCOOL HyperHeat and VersaPro™ systems lies in their heating performance and climate suitability. Both systems use the same VersaPro central ducted air handlers, but they pair with different outdoor condensers.

is engineered for extreme cold climates, maintaining powerful heating performance even in sub-zero temperatures. These systems use advanced inverter technology and are optimized for high-efficiency heating during the winter, making them ideal for northern regions.

offers a more balanced solution for moderate climates with excellent year-round comfort, delivering efficient heating and cooling at a lower price point. It's a great choice if you live in a region with mild to moderate winters.

In short:

✔️ Choose HyperHeat if you need reliable heating in freezing conditions.

✔️ Choose VersaPro for year-round performance in temperate climates.

Yes — both the MRCOOL HyperHeat and VersaPro™ systems are designed to be DIY-installable without the need for special HVAC tools or professional certification.

The outdoor condenser units are pre-charged with R-454B refrigerant, and the included line sets are vacuum-sealed, leak-tested, and pre-charged as well. This means there's no need to vacuum the system or handle refrigerant, which is typically the most complex part of HVAC installation.

The system includes:

While many homeowners successfully install these systems themselves, you should be comfortable with basic tools, lifting equipment, and following detailed instructions. For more complex installs (especially involving ductwork or electrical), you may still want to consult a licensed HVAC technician or electrician.

✔️ These are the most DIY-friendly central ducted systems available — ideal for handy homeowners and contractors alike.

No — if you’re using the pre-charged line sets designed for these systems, you do not need to vacuum or charge refrigerant. The MRCOOL HyperHeat and VersaPro™ systems offer flexibility for both DIY installation and traditional professional installation.

For DIY installation, the system uses MRCOOL's pre-charged, vacuum-sealed quick-connect line sets, which come filled with the correct amount of R-454B refrigerant from the factory. These line sets eliminate the need for handling refrigerant or using a vacuum pump — making the installation safe and straightforward for handy homeowners.

For professional installation, HVAC technicians can install the system using traditional methods — including field-flared copper, custom line lengths, and on-site refrigerant charging, if desired. This is especially useful for custom applications or when the standard line set lengths don’t meet the project’s needs.

✅ Whether you’re going the DIY route or working with a licensed contractor, the system is built to support both installation methods effectively.

The coverage area for MRCOOL HyperHeat and VersaPro™ central ducted systems depends on the system size (BTU rating), your home's insulation, ceiling height, layout, and climate zone. Below is a general guideline based on average conditions:

• 18,000 BTU up to 750 sq ft
• 24,000 BTU up to 1,000 sq ft
• 30,000 BTU up to 1,250 sq ft
• 36,000 BTU up to 1,500 sq ft
• 48,000 BTU up to 2,000 sq ft
• 60,000 BTU up to 2,500 sq ft
  

These figures are based on typical residential conditions. Homes in colder climates, with poor insulation or open floor plans, may require a larger system.

🔧 For best results, we always recommend performing a Manual J load calculation or consulting with an HVAC professional to ensure you're choosing the right size for your space.

Each VersaPro™ air handler is compact and designed for flexible installation. Here are the approximate dimensions by size:

• 18k: 45.75" H × 17.5" W × 21" D
• 24k: 45.75" H × 17.5" W × 21" D
• 30k: 45.75" H × 17.5" W × 21" D
• 36k: 45.75" H × 21.5" W × 21" D
• 48k: 53.75" H × 24.5" W × 21" D
• 60k: 53.75" H × 24.5" W × 21" D

🧰 These multi-position air handlers are suitable for upflow, downflow, or horizontal installs in tight spaces like attics, closets, or basements.

The Difference is in the Condenser

• VersaPro Condenser: Best for mild to moderate climates, offering balanced cooling and heating.
  
• HyperHeat Condenser: Built for extreme cold climates, using enhanced inverter technology to maintain heating even in sub-zero temps.
  

So while the outdoor unit (condenser) changes depending on your climate needs, the air handler remains the same — simplifying inventory, installation, and serviceability without sacrificing performance.

✅ One air handler, two condenser options — giving customers the flexibility to choose performance based on climate, not compatibility.
