Heating and Cooling in Salem: Heat Pumps for Problem Rooms

Salem’s mix of older capes, ranches, and newer builds all hit the same walls: one room that never gets comfortable, oil heat that’s expensive to run, or AC window units every summer. Mitsubishi cold-climate heat pumps — built to keep heating at outdoor temperatures as low as −13°F — solve the problem-room case and the whole-home case, quietly and without ductwork where none exists. We also service and replace furnaces and boilers.

Recent Heating & Cooling Projects in Salem

Two Mitsubishi single-zone installs completed in Salem this year, alongside repairs and maintenance calls across town:

Single-Zone Mitsubishi Wall-Mount — Salem (summer 2026)

One outdoor condenser, one indoor wall-mounted unit, installed in a day — heating and cooling for the main living space of a small, open-plan home. Single-zone systems like this are among the most common installs we do.

Slim-Ducted Mitsubishi for a Problem Room — Salem (winter 2026)

For a room that never stayed comfortable, we installed a slim-ducted indoor unit hidden in the ceiling paired with a cold-climate-rated outdoor unit — invisible from the living space, quiet, and effective down to the coldest days.
