MRCOOL DIY Mini Split - 39,000 BTU 4 Zone Ductless Air Conditioner and Heat Pump, DIY-B-436HP09090912

Imagine offering your customers a cutting-edge climate solution that delivers precise comfort across multiple rooms, all with effortless installation. The MRCOOL DIY Mini Split 39,000 BTU 4 Zone system is designed for contractors and business owners who want to provide reliable, efficient, and customizable HVAC solutions without the hassle of complex setups. Perfect for homes, garages, workshops, and commercial spaces, this system empowers you to meet diverse climate needs with confidence.

Robust and Efficient Condenser

At the core is a powerful 36,000 BTU condenser, built to last with a Gold Fin® coating that protects against corrosion — essential for coastal or harsh environments. With an impressive 21.5 SEER2 and 8.5 HSPF-5 rating, this system ensures energy savings while maintaining powerful cooling and heating performance. It reliably heats even when outdoor temperatures drop as low as -13°F, keeping your clients comfortable year-round.

Tailored Air Handlers for Every Room

Help your customers enjoy perfect comfort in every space with two air handler options:

  • 9,000 BTU Air Handler: Ideal for smaller rooms from 180 to 375 square feet, such as bedrooms or home offices, delivering consistent and quiet climate control.
  • 12,000 BTU Air Handler: Designed for medium-sized rooms between 376 and 500 square feet, perfect for living rooms, workshops, or larger areas needing steady temperature management.

Each air handler offers multiple modes — COOL, HEAT, AUTO, DRY, and SLEEP — allowing your clients to customize their environment effortlessly.

Installation Made Simple

Imagine cutting down installation time dramatically. MRCOOL's patented Pre-Charged Quick Connect Line Sets eliminate the need for vacuum pumps, refrigerant handling, or specialized tools. The lightweight, compact design of the air handlers makes mounting quick and easy, so you can complete jobs faster and take on more projects with ease.

Smart Control for Ultimate Convenience

Your customers will love the SmartHVAC app compatibility, which allows them to control their system remotely from anywhere in the world. Whether adjusting temperature, switching modes, or setting schedules, this feature adds a modern touch that enhances user satisfaction and loyalty.

The cost to install a MRCOOL mini split system typically ranges from $2,500 to $6,000 for most residential applications, depending on system size, number of zones, and whether you choose DIY or professional installation.

Other Questions
