Long description

Full, ready‑to‑install 5‑zone comfort kit

This bundle delivers a true whole‑home upgrade in one package. At its core is MRCOOL’s new 5th Generation 36k BTU multi‑zone condenser, designed for quick DIY installation, ultra‑high efficiency, and long‑term reliability. Paired with two versatile indoor units and two pre‑charged 25‑ft line sets, this kit is built to serve five spaces—ideal for a small house, a large open floor plan, or a mix of bedrooms, office, and bonus rooms.

 

What sets it apart:

• Real DIY, not just DIY‑friendly. Pre‑charged R‑454B Quick‑Connect lines remove the need for a vacuum pump or refrigerant handling during installation, cutting labor time, tools, and hassle.
• Industry‑leading efficiency for a system this size. Designed to hit very high SEER2 and HSPF2 ratings for strong cooling and heating performance, so monthly energy costs stay lower than many traditional systems.
• Smart app control plus voice assistants. Use MRCOOL’s app or your Amazon Alexa / Google Home for hands‑free comfort control, scheduling, and energy monitoring.
• Future‑ready refrigerant and controls. Uses R‑454B, a lower‑impact refrigerant compared to older common blends, paired with an improved control cable and smart features introduced with MRCOOL’s 5th‑gen lineup. Independent installer outlets note the 5th‑gen upgrade focuses on eco‑friendliness, higher efficiency, and enhanced controls.  

 

The result: professional‑grade comfort across five zones, installed by a homeowner, without compromising energy efficiency or long‑term reliability.

Key features and benefits

Efficiency and performance

• High seasonal efficiency reduces electric use, especially compared to older equipment in many homes. Exact SEER2/HSPF2 numbers are manufacturer‑specified for the 5th‑gen condensers; the 5th‑gen line emphasizes higher efficiency than previous MRCOOL generations.  
• Strong heating even in cold weather with inverter heat pump tech and smart controls—meaning more usable heating hours and less reliance on costly backup heat.

  

Lower‑impact refrigerant

• Uses R‑454B, a newer, lower‑global‑warming‑potential refrigerant relative to older common blends. This aligns with industry moves toward more eco‑friendly options and long‑range regulation compliance. Third‑party installers and sellers highlight R‑454B as a key upgrade in 5th‑gen systems.  

  

Smart, modern controls

• SmartHVAC app + voice assistants built into the platform allow scheduling, zone management, and monitoring from anywhere.
• Follow‑Me and multiple modes to tailor airflow, humidity control, and quiet operation to the needs of each room.

 

Installation simplicity & safety

• Pre‑charged Quick‑Connect line sets mean no refrigerant filling or vacuum pumps for the install—huge savings in tools, time, and complexity.
• DIYPro cable and improved controls reduce the need for conduit and improve system communication, as noted in 5th‑gen updates.
