Founded in O’Fallon, MO in 2003, YMGI Group began with a simple mission: To provide efficient, clean and healthy cooling and heating products, quality service and comfort solutions to each of our customers.

Because ductless systems eliminate dust, mold and fungus growing unseen in a structures ventilation system, YMGI believes that Ductless air terminals are the best solution for keeping your home or business healthy and comfortable. It also eliminates air flow restriction and air noise, making your home and office more comfortable and more peaceful.

YMGI DC Inverter Multiple Zone Systems are energy efficient and allow the flexibility to personalize your comfort from room to room. Operation, maintenance and service are also simpler and less expensive than central air systems.

We renewed our commitment to this mission with our new YMGI DC Inverter VRF Systems. A technology that will allow you to replace the traditional AC and Furnace with a single system. This state-of-the-art HVAC Heat Pump technology runs at 80% efficiency in ambient temperatures as low as -22 degrees F. This all electric system allows you to reduce your carbon footprint by eliminating your need for burning gas or oil in your furnace.

YMGI strives to innovate and push the frontier of HVAC technologies with our Solar Assisted Mini-Split and VRF products. Both allow you to directly wire your HVAC system to PV Solar Panel Arrays to reduce your energy use even further and provide one of the greenest ways to heat and cool.

As we continue to grow, YMGI offers more and more products designed to keep you comfortable while promoting energy efficiency and sustainability. For over a decade, our commitment to our goals and vision have never changed. We continue to pursuit our original goals: greater and more personalized comfort, energy efficiency, healthier air, and the production of the most environmentally friendly products available.

From our new home (still located in O’Fallon, MO) we continue to expand operations throughout the United States and Canada. Our ultimate mission is to become your trusted partner and provide you peaceful, efficient and personalized comfort in your home and your business.
