Frequently Asked Questions

How much money can I save using a Mitsubishi Electric system for heat instead of electric baseboard?

Mitsubishi Electric ductless systems can be significantly more efficient than electric baseboard heat. Depending on outdoor temperatures and operating conditions, they can operate at approximately 2 to 4.5 times the efficiency of electric resistance heat. Actual savings will vary based on your home, outdoor temperatures, utility rates, and how you use the system.

What is Mitsubishi Electric Hyper-Heat, and does it really work during cold Northeastern Pennsylvania winters?

Mitsubishi Electric Hyper-Heat is cold-climate heat pump technology designed to provide reliable heating even when outdoor temperatures drop well below freezing. These systems are specifically designed to maintain strong heating performance in cold weather, making them an excellent option for the winters we experience here in Northeastern Pennsylvania.

Proper equipment selection and system design are important. All Mechanical evaluates your home, heating requirements, and existing system to determine whether Hyper-Heat is the right solution for your home.

Do I need existing ductwork for a Mitsubishi Electric heating and cooling system?

No. One of the advantages of Mitsubishi Electric is its flexibility. Ductless systems don't require traditional ductwork, making them particularly useful for older homes, additions, finished spaces, and homes with electric baseboard heat. Mitsubishi Electric also offers ducted solutions for homes where ductwork makes sense.

Do I need a Mitsubishi Electric unit in every room of my house?

Not necessarily. Every home is different, and the right system design depends heavily on your home's layout, construction, comfort needs, and how the rooms are used. Some homes may be very comfortable with just one or two indoor units, while others benefit from additional zones. All Mechanical evaluates your home and designs the system around your specific needs rather than taking a one-size-fits-all approach.

Do Mitsubishi Electric systems have to use those units that hang on the wall?

No. Wall-mounted units are probably the most recognizable, but Mitsubishi Electric offers several indoor-unit options. Depending on your home and system design, options can include wall-mounted units, low-wall/floor-mounted units, ceiling cassettes, and ducted air handlers for central systems.
