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.
