What Are the Advantages of Mitsubishi Ductless?

If you are considering a new air conditioner or heater for a new structure or system replacement, a Mitsubishi ductless system can be the ideal solution for many homes and businesses. Ductless systems are installed faster than central heat or air systems and require only a single small hole for the lines from the wall unit to the condenser. Mitsubishi is a reputable heating and air conditioning brand and a leader in energy-efficient technology in the United States.

Mitsubishi ductless systems can fit a variety of applications and have several advantages over other indoor comfort solutions:

  • Supplement your existing central air conditioner or furnace
  • Variable refrigerant flow and inverter system deliver improved energy efficiency for lower heating and cooling bills
  • Integrated air filtration system to improve your indoor air quality
  • Lower maintenance costs than central heating and cooling
  • Comfort zones provide seamless comfort with a range of control

Installation and Replacement

A ductless air conditioning or heating system can be installed faster than the typical central air or heating system. Drilling and cutting holes in the wall are minimized because ductless systems require no ductwork or registers. A Mitsubishi ductless system instead uses a wall-mounted climate control unit or several units divided into comfort zones. Comfort zones deliver heating or cooling without energy waste or hot and cold spots. A ductless system makes an ideal supplement to your existing HVAC system or a reliable and efficient replacement for your old system.


How can a Mitsubishi ductless heating or air conditioning system lower your maintenance costs? Ductless systems do not require maintenance, replacement, or cleaning of your ductwork. The system includes a built-in air filter that should be cleaned during your annual maintenance session, saving on expendable filters. Ductless systems also have fewer mechanical parts, so wear and tear are less of an issue.

Our experienced technicians will inspect your Mitsubishi ductless system inside your home or business and the lines and condenser outside. We clean the air filter and coils to make sure air can flow easily through the system, and we provide preventative maintenance like leak detection and refrigerant recharging.


An inspection of your Mitsubishi ductless system can make sure it is ready to deliver uninterrupted comfort when you need it. An inspection from our technicians provides a thorough analysis of the health of your system, so we can inform you if your ductless system is ready to serve you long-term or if it could use service to reach its optimum performance. A routine inspection can save you money on major repairs, and prevent a failure of your ductless system that results in a temporary loss of your heating or cooling.


Sometimes your ductless system could use a boost in efficiency, airflow, or comfort. When your ductless system isn't quite performing up to your expectations, Wighton's can help you get the performance you expect with a Mitsubishi ductless tune-up. A tune-up is a maintenance session that is independent of your annual or routine maintenance. Our technicians will improve the comfort, efficiency, and reliability your ductless system provides with affordable adjustments and cleaning. If there is an issue with your ductless system, we will inform you and let you decide if we perform the repair on the spot.
