MRCOOL ductless mini-split installation in Bohemia, NY — heating and cooling for older homes, additions, and spaces without ductwork.
A large share of the homes in Bohemia were built before central air was standard, which means window units in the summer and baseboard heat in the winter — neither particularly efficient, and neither comfortable. MRCOOL ductless mini-splits solve both problems in a single system with no ductwork required.
Milton's Construction is an authorized MRCOOL installer. We size the system for your home's actual load, handle the electrical work and line set installation, and register the equipment for the full manufacturer warranty.

Ranches and Capes without existing ductwork are the ideal candidates for a ductless system. Running new ducts through a finished home is expensive and invasive — it means cutting through ceilings and walls and boxing around soffits that were not designed for that work. A MRCOOL mini-split installs in a day or two with a small hole through the wall for the refrigerant line and a conduit for the electrical connection.
For additions and dormer conversions, ductless is almost always the right call. Tying into an existing forced-air system through a new second floor is complicated and usually undersizes the new space anyway. A dedicated mini-split for the addition is cleaner and more efficient.


Most single-zone installations take one day. Multi-zone systems serving several rooms take two to three days. We handle the permit through Town of Islip when required and schedule the electrical inspection.
A single-zone MRCOOL system typically runs in the low to mid thousands installed, depending on BTU capacity and line set length. Multi-zone systems are priced by configuration. A free written estimate gives you the exact number — call or text 631-741-0199.
Yes. Modern heat pump mini-splits maintain efficiency down to well below freezing. Long Island winters are well within the operating range for MRCOOL's heat pump units, and many homeowners use them as their primary heat source.
Absolutely. A single-zone system is exactly how most projects start. If you decide to add more zones later, we can often use the same outdoor unit if it was sized with that in mind — we plan for it upfront.
Yes. HVAC installations in Bohemia require a mechanical permit through Town of Islip Building Division. We pull the permit and schedule the inspection as part of the installation.
