Mini Split Installation

A single-zone ductless mini split installation in Southern NH starts around $5,525 installed. That price covers the equipment, all electrical work, permits, and our workmanship warranty. Multi-zone systems with 2 or 3 indoor units typically run $8,500 to $19,500+ depending on the number of zones and complexity. NHSaves utility rebates and the New England Heat Pump Accelerator can reduce those costs for qualifying systems. We provide free written estimates with everything included upfront.

Central A/C installation starts around $6,550 installed for a standard system. That includes the equipment, all labor, electrical work, permits, and our workmanship warranty. Higher-efficiency units or systems requiring ductwork modifications will cost more. We provide free written estimates with everything included upfront.

Central A/C uses ductwork to cool your entire home from one system. A ductless mini split uses individual wall units to cool specific zones, with no ductwork required. That makes mini splits ideal for homes with boilers, additions, or any space where running ducts isn't practical. Mini splits also provide heat, which makes them a year-round comfort solution.

Yes, and they're significant. NH utility companies offer NHSaves rebates based on system size and type for qualifying heat pump systems. We identify every incentive you qualify for during your free estimate and apply the NE Heat Pump Accelerator point-of-sale discount right at purchase. NHSaves rebates are filed through your utility using your account information, and we help you complete those applications.

Yes. Cold-climate heat pumps from Mitsubishi, Daikin, and Bosch operate efficiently down to -13°F, which is well below any NH winter temperature. Many Southern NH homeowners use them as the primary heating system, or pair them with an existing furnace or boiler in a hybrid, dual fuel setup that runs the heat pump most of the year and the furnace only in the coldest stretches.

Most mini split systems with one or two indoor units are completed in one day. Systems with three indoor units typically take two days, and four to five indoor units take about three days. We give you a clear timeline in your written estimate before any work begins.
