Today's Hours 8am - 11pm estTraditional package units used in residential and mobile home applications often rely on single-stage or limited multi-stage compressors, which can lead to inconsistent temperatures, higher energy consumption, and frequent on/off cycling. This is especially noticeable in smaller homes or manufactured housing, where systems tend to overshoot temperature setpoints or struggle to maintain steady comfort.
Additionally, many standard package units are designed around older technology, making them less efficient and less adaptable to changing conditions throughout the day.
MRCOOL inverter heat pump package units are designed to solve these common issues by delivering variable-speed performance that adjusts in real time, providing smoother, more efficient heating and cooling.


MRCOOL inverter heat pump package units are designed for flexible, all-in-one heating and cooling across a variety of applications, making them a strong fit for residential homes, mobile and modular housing, and even small commercial spaces.
These systems are commonly used in:
Because all components are housed in a single outdoor cabinet, installation is more streamlined than traditional split systems. MRCOOL package units can be installed in two primary configurations:
This flexibility allows the system to adapt to different building types and layouts while maintaining efficient, centralized heating and cooling performance.
Choosing the right size MRCOOL inverter package unit is critical to achieving the best performance, efficiency, and comfort. Systems that are too small may struggle to keep up with demand, while oversized systems can reduce efficiency and lead to inconsistent temperatures.
Most residential applications fall within 2 ton to 5 ton package unit sizes, depending on the home’s square footage, layout, and insulation.
An inverter heat pump package unit is an all-in-one HVAC system that uses a variable-speed compressor to provide both heating and cooling. Unlike traditional systems, it adjusts output based on demand, improving efficiency and comfort.
Yes, these systems are a great fit for mobile and manufactured homes because they provide compact, all-in-one heating and cooling with improved efficiency compared to traditional package units.
Inverter systems are typically more efficient because they avoid constant on/off cycling and instead operate at variable speeds to match demand. This can lead to lower energy usage and more consistent indoor temperatures.
