Mitsubishi Mini Split Heating

Because our Winter’s here in Montgomery County and Conroe, Texas are relatively mild, ductless mini splits have become a popular heating choice for both home and business owners. Ductless mini splits are a relatively new HVAC technology, coming to the market after central furnace and air conditioning systems. They can be much more efficient at both heating and cooling your space, especially compared to old central furnace and AC models. They are also highly customizable, allowing you to efficiently add units to zone your space exactly how you want it. We are a Mitsubishi Electric Diamond Elite Contractor, and we’re sure we have the perfect Mitsubishi mini split to keep your home or business comfortable all winter long here in Montgomery County.

Hyper-Heat(H2i®)available in Mitsubishi mini split models makes sure your system heats at high effectiveness and efficiency even when the temperature outside is close to ºF. Though we don’t see those low temperatures here, you’ll have peace of mind knowing your system is there to heat effectively when those Conroe, Texas winter’s hit.
