Frequently Asked Questions

To switch modes on a ductless mini-split heat pump ALL the heads running off the same condenser need to be put in the same mode. So if you have a 3-port Mitsubishi ductless system, with heads in your office, living room, and kitchen, you cannot switch from one mode to another in just your office without putting the ones in the living room and kitchen in the same mode.

Another potential answer: you may not be able to switch over from cooling to heat is that the symbols on some models can be very similar. One brand, for example, has a sun to indicate heat and a snowflake for air conditioning. Without checking closely it is possible to put it in one of those modes when in fact you want the other so it is always recommended to double check!

The ductless mini-splits installed by High Efficiency do not allow the temperature to be set at lower than 55° when in air conditioning mode. You can, however, turn the unit to the dehumidifying mode and the temperate can drop below 55°, but you cannot control how low it will go.

Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Furnaces heat air and distribute the heated air through the house using ducts.

When it comes to making sure your home is efficiently heated and cooled, your HVAC system is only part of solution. If the envelope of your home is not well sealed you will experience energy loss through air leakage. It is recommended to get an evaluation of air leakage in your home. The Mass Save program offers no-cost home energy assessments and incentivized weatherization and air sealing. High Efficiency’s sister companies Cape Cod Energy Solutions and Home Contracting Solutions can provide these services.
