As an authorized MRCOOL installer, Milton's Construction puts ductless mini-split and DC inverter heat pump systems into North Babylon homes that were built without ductwork and cannot practically add it now.
Most of the ranches and Capes in North Babylon were built with oil-fired baseboard heat and window air conditioners. Installing central forced-air would require routing duct chases through finished ceilings and walls, disrupting every room in the house. For many homeowners, that kind of disruption is not realistic, especially when an addition or a converted room needs its own temperature zone anyway. Ductless mini-split systems solve this cleanly.
We are an authorized MRCOOL distributor and installer, which means we carry the equipment, we know the product line thoroughly, and we stand behind the installation. MRCOOL DC inverter systems heat and cool efficiently down to very low outdoor temperatures, making them a legitimate year-round solution for Long Island's climate, not just a summer cooling workaround. A single outdoor compressor can serve multiple indoor heads, each with its own thermostat, making it easy to zone a new addition separately from the rest of the house.
A 1955 ranch in North Babylon was designed around gravity or baseboard heat, with no provision for a central air handler or supply trunks. Adding ducts retroactively means either dropping a false ceiling in the living room or threading flex duct through attic spaces that were never designed for it. Ductless avoids all of that. The refrigerant line set runs through a small hole in the exterior wall, the indoor head mounts high on the wall, and the outdoor compressor sits on a pad next to the house. Installation typically takes one to two days and does not require any major demolition.
For additions and converted rooms, a dedicated mini-split head is almost always the right answer. Extending existing ductwork to a new room at the back of the house means undersizing the system for the original rooms or running long, inefficient duct runs. A new zone on the existing compressor handles the addition cleanly, or we size a separate compressor if the addition is large enough to warrant it.
A mini-split installation in North Babylon requires an electrical permit through the Town of Babylon Building Division in Lindenhurst. We file the permit, schedule the inspection, and have a licensed electrician on our crew run the dedicated circuit. You do not need to coordinate a separate HVAC contractor and a separate electrician. As an authorized MRCOOL installer, we handle equipment procurement, installation, startup, and registration of the manufacturer warranty.
Typical cost for a single-zone system in one room or one addition runs in the range of $4,000 to $8,000 installed, including the permit and electrical work. Multi-zone systems vary based on the number of heads and the total BTU load required. A free written estimate gives you the accurate number for your specific home.
Yes. MRCOOL DC inverter heat pumps are rated to operate efficiently down to negative temperatures. For Long Island winters, they are a legitimate primary heating source for the zones they serve. Many of our customers use them to heat additions and converted rooms year-round without any supplemental heat.
Yes. Any mini-split installation that requires a new dedicated electrical circuit needs an electrical permit from the Town of Babylon Building Division. We file the permit and have it inspected. Unpermitted HVAC work creates issues at resale and is not code-compliant.
Yes, and that is actually one of the most common reasons we install them. When we build a dormer or a rear extension in North Babylon, we almost always recommend a dedicated mini-split head for that space rather than trying to extend the existing duct system. It gives the addition its own thermostat, performs better, and does not rob airflow from the rest of the house.
