Mitsubishi ductless mini-split installation in Essex County, MA. Zone-by-zone comfort, up to 3× the efficiency of baseboard heat, and whisper-quiet operation — installed by electricians who've been doing this work since 1984.
A ductless mini-split moves heat rather than generating it — making it dramatically more efficient than any combustion-based system. In winter, it extracts heat from outdoor air (even at -13°F for cold-climate models) and moves it inside. In summer, it runs in reverse, moving heat out. One system, year-round comfort.
The system has two components: an outdoor compressor unit and one or more indoor air handlers mounted high on the wall. A small conduit (about 3 inches) runs through the wall connecting them. No ductwork. No dropped ceilings. Minimal structural disruption.
💡 The real-world numbers: Massachusetts homeowners switching from oil heat to Mitsubishi mini-splits typically see heating cost reductions of 40–60% — and eliminate their fuel delivery entirely.
Primary zone — heat and cool where you spend time most

Make a previously unusable space comfortable year-round
Most homes in Essex County were built between 1920 and 1985 — before central air conditioning was standard. These homes often have hot water baseboard heat (great for winter, nothing for summer), or aging forced-air systems with leaky ducts that lose 20–30% of their energy before reaching a room. Adding central AC or replacing the whole HVAC system means tearing into walls, dropping ceilings, and finding space for ductwork that simply wasn't designed into the structure.
Most Essex County homes with oil or propane heat spend $3,000–$6,000+ per year on fuel. A heat pump system doesn't eliminate electricity costs, but electricity is dramatically cheaper per unit of heat than oil or propane — especially when the heat pump is working at 300–400% efficiency.
If you have or plan to add solar, the picture gets even better: you're running the heat pump on energy you're generating. Net heating cost approaches zero on sunny days.
Ductless systems have become popular enough that you'll see them installed by everyone from licensed HVAC contractors to handymen watching YouTube tutorials. The quality range is enormous. A poorly installed system won't reach rated efficiency, will run callback issues, and may void the manufacturer warranty. Here's what the difference looks like:
We're electricians first. Every mini-split installation includes a dedicated electrical circuit, properly sized and permitted. Most HVAC contractors sub out the electrical work. We do both — better coordination, one point of contact, cleaner installation.
Mitsubishi makes the dominant mini-split system in the Massachusetts market — their Hyper Heat line is specifically engineered for cold-climate performance, maintaining rated capacity down to -13°F. That matters here. A generic mini-split from a big-box store drops to 60–70% capacity when it gets cold outside. Mitsubishi Hyper Heat does not.
We've installed Mitsubishi systems across Essex County — in Victorian three-deckers in Salem, 1960s colonials in Reading, and modern additions in Andover. We know how these systems perform in our climate and what to look for during installation.
Zolotas Electric was founded by John Zolotas in 1984. His son Greg runs the company today — second-generation master electricians who've spent four decades learning the homes of Essex County from the inside out.
When Mitsubishi mini-splits became the clear choice for Massachusetts homeowners, we added them to our work. Not because they were fashionable — because they're genuinely the right answer for the homes we serve. We don't push products. We assess your home, tell you what makes sense, and install it properly.
Answer 8 quick questions about your home — heating type, panel size, whether you have solar — and we'll send you a personalized roadmap showing which upgrades make sense for your specific situation.
We'll assess your home, walk through which zones make the most sense to add ductless, calculate your efficiency gain, and give you a clear quote. No surprises. No upsell.
