Why Mitsubishi Electric Stands Out

Mitsubishi Electric systems are built for comfort, energy efficiency, and flexibility, making them a standout choice for heating and cooling your home or business. 

Here’s what sets these systems apart:

  • Zoned comfort. Mitsubishi Electric systems allow you to control the temperature in individual rooms or zones, so you’re only heating or cooling the spaces you use. This gives you ultimate control over your comfort while avoiding the waste of conditioning unused areas.
  • Energy-saving performance. These systems feature inverter-driven compressors and smart sensors that adjust the system’s performance to match your exact needs. By avoiding energy waste, Mitsubishi Electric systems keep your utility bills lower while maintaining a steady, comfortable temperature year-round.
  • Quiet operation. Unlike traditional HVAC systems, Mitsubishi Electric units operate quietly, making them ideal for spaces where noise matters, such as bedrooms, offices, or quiet zones.
  • Flexible installation options. Mitsubishi Electric systems offer flexible installation options that work for your space. Whether wall-mounted, recessed into the ceiling, or integrated with existing ducts, these sleek units can be placed almost anywhere in your home or building—ideal for spaces where traditional ductwork won’t fit.
  • No major remodel required. Ductless systems eliminate costly, invasive renovations to install new ductwork. They are the perfect solution for homes or businesses with no existing ducts, including older buildings or additions, offering a simple and cost-effective upgrade.
  • All-season performance. Mitsubishi Electric systems use heat pump technology that provides efficient heating in the winter and cooling in the summer. Even during Michigan’s coldest months, these systems work to keep your space comfortable, making them a true all-year solution.
  • Environmentally friendly. Mitsubishi Electric systems are designed with sustainability in mind. Their high-efficiency performance means they consume less energy, resulting in a smaller carbon footprint, perfect for eco-conscious homeowners and businesses.

Mitsubishi Electric vs. Traditional HVAC

Traditional central air systems heat or cool an entire building at once, even if you’re only using a few rooms. Mitsubishi Electric systems give you targeted control, so you’re not using energy where you don’t need to.

Other key differences:

  • No duct loss. Ducts can lose 20–30% of airflow through leaks. Ductless systems avoid that entirely.
  • Smarter zoning. Heat one room while cooling another, or turn off units in unused areas.
  • More installation flexibility.  Perfect for spaces where ducts won’t reach.

    "10/10 Service!"
    Had Customer Engineering come out to my restaurant to diagnose my furnace and walk-in freezer. Brandon and Skylar, the techs, were amazing. Extremely friendly and knowledgeable. I will be using them for all my HVAC needs moving forward.

    Chaz went above and beyond! He fixed my main house furnace and also advised me on my ceiling-mounted furnace in my back building. Thank you for your quick response. I will use you again!

    "By far the most professional and reliable company."
    Every employee I have had the pleasure of dealing with has been top-notch. Today's visit by Tyler for annual maintenance was great. He was punctual, friendly, and professional.

    "Custom Engineering took care of us right away!"
    Our initial call was after hours and not an emergency. We received a call first thing the next morning, and they came out within a few hours. Both gentlemen were very professional and knowledgeable, and were able to repair our furnace right then and there.
    - Reid K.
    "They really came through!"
    Quick, efficient, and friendly service from both office staff and techs. Fair pricing. Grateful for their help on a freezing day when our furnace failed. Feared the worst. Highly recommend this company!
