The MRCOOL Universal 4-5 Ton 18 SEER Central Heat Pump Split System with 35 ft. Lineset is engineered for contractors and business owners who need a powerful, efficient HVAC solution that adapts to larger spaces and more complex installations. Designed to deliver superior comfort, energy savings, and simplified installation, this system is ideal for residential and light commercial projects up to 2,500 square feet.
This system offers excellent heating and cooling capacity with an inverter compressor that modulates output to match demand precisely. It provides 100% heating capacity down to 14°F and operates reliably in cold conditions as low as -22°F. Cooling performance is maintained up to 109.4°F, ensuring consistent comfort throughout the year.
Equipped with a 35 ft. pre-charged No-Vac Quick Connect line set, this system allows your installation team to skip vacuum pumps and refrigerant charging, saving time and reducing complexity. The kink-resistant, UV-protected insulation sleeve protects the line set during bends and outdoor exposure. The screw-on quick connect valves simplify connections, making the installation process faster and more reliable.
The air handler supports multi-position installation—upflow or horizontal—offering flexibility to fit various duct layouts and jobsite requirements.
The system operates quietly thanks to specially designed internal fan blades. The air handler features a fire-proof electrical box with anti-shock protection for enhanced safety. Additionally, the easy-to-clean metal filter helps prevent fire hazards, corrosion, and deterioration, ensuring long-lasting performance.
Choose the MRCOOL Universal 4-5 Ton 18 SEER Central Heat Pump Split System with 35 ft. Lineset for a reliable, efficient, and installer-friendly solution that meets the demands of your larger HVAC projects.

"Their technical expertise in commercial HVAC systems is outstanding. From equipment selection to installation support, they provided everything we needed. The bulk pricing saved us thousands on our multi-building project, and their 24/7 technical support kept us running smoothly."- Marcus R., HVAC Project Manager, 06/24

A MRCOOL mini split typically lasts 12 to 20 years with proper installation and regular maintenance.
MRCOOL HVAC systems are designed and distributed by MRCOOL LLC, an American company based in Kentucky, but they are primarily manufactured by established HVAC companies in China, such as Midea and Gree, under contract for MRCOOL.
MRCOOL offers affordable, DIY-friendly HVAC systems with solid performance and easy installation, while Mitsubishi is known for premium, industry-leading mini splits with superior reliability, advanced features, and higher efficiency—but at a higher price point and typically requiring professional installation.
No, it's not cheaper to leave a mini split on all the time; turning it off or adjusting the temperature when not needed saves more energy and money.
MRCOOL mini splits are generally better for DIY installation and warranty support, while Pioneer mini splits are often more budget-friendly but may require professional installation and have less robust support; overall, MRCOOL is preferred for ease of setup and customer service, while Pioneer is a good choice for lower upfront cost.
