Thousands of Ductless Systems Installed Across Southern NH
We have been installing ductless mini splits in Southern NH for decades. That experience shows in how we size systems, route line sets, and position indoor units for maximum comfort and minimum visual impact. A mini split is only as good as the installation behind it.
Mini splits are the right solution for homes with oil boilers and no ductwork, room additions, older homes where running new ducts is not practical, and anyone who wants efficient zone-controlled heating and cooling without a major renovation.
Who Mini Splits Are Right For
Homes With Oil or Propane Heat
If you heat with oil or propane and have no ductwork, a mini split adds both heating and cooling without a major renovation. Most customers see meaningful fuel savings after switching.
Zone-by-Zone Temperature Control
Each indoor unit operates independently. Bedrooms, living areas, and home offices can each be set to a different temperature. No more fighting over the thermostat.
Additions and Hard-to-Reach Spaces
Finished basements, sunrooms, garage apartments, and home additions that your existing system cannot reach. A mini split is the clean solution that does not require touching existing ductwork.
High Efficiency Down to -13°F
Cold-climate models from Mitsubishi, Bosch, Daikin, and LG are engineered for NH winters. These are not the mini splits of ten years ago. They run efficiently even on the coldest days.
Mini Split Systems We Install
Single-Zone Mini Splits
One outdoor unit paired with one indoor wall unit. The most common setup for adding heating and cooling to a room, garage apartment, finished basement, or a home that needs one primary comfort system. Clean, quiet, and efficient.
- One outdoor condenser, one indoor wall unit
- Most installations completed in one day
- Requires only a small hole through the wall
- Heating and cooling in one system
- Wi-Fi control available on most models
Multi-Zone Mini Splits
One outdoor unit connected to two, three, or four indoor units throughout the home. Each zone is controlled independently. The right solution when you want to condition multiple rooms or floors without running new ductwork through the whole house.
- One outdoor unit, up to 4 indoor zones
- Each zone has its own thermostat control
- More efficient than running separate single-zone systems
- Ideal for whole-home ductless heating and cooling
- Works alongside existing oil or gas heat as a hybrid setup

Mini Split FAQ
How much does mini split installation cost in NH?
A single-zone ductless mini split installation in Southern NH typically runs $5,525 to $7,000 fully installed, depending on brand, BTU size, and how complex the installation is. Multi-zone systems cost more. NHSaves rebates and the NE Heat Pump Accelerator can meaningfully reduce your net cost. We provide free written estimates with all costs included upfront so there are no surprises.
Can a mini split heat my home through a New Hampshire winter?
Yes. Cold-climate mini splits from Mitsubishi, Bosch, Daikin, and LG are rated to operate efficiently down to -13°F. Many NH homeowners use them as their primary heat source. Others pair them with an existing oil or gas system in a hybrid setup where the mini split handles the majority of heating and the boiler or furnace kicks in as backup on the coldest days. Both approaches work well.
Do I need ductwork for a mini split?
No. That is one of the main advantages of a ductless system. The indoor and outdoor units connect through a small hole in the wall (typically about 3 inches) for the refrigerant line, electrical, and condensate drain. No ductwork required. This makes mini splits the go-to solution for homes with boilers, older homes without existing ducts, and room additions.
What is the difference between a mini split and a heat pump?
A mini split is a type of heat pump, specifically a ductless one. The term "mini split" refers to the two-part system: a small outdoor compressor and one or more indoor air handlers connected by a line set. Traditional heat pumps use ductwork to distribute air. Mini splits deliver conditioned air directly into the room, which is more efficient and allows zone-by-zone control.
Are there rebates for mini split installation in NH?
Yes. NHSaves offers $250/ton for standard installations and $1,250/ton when replacing primary electric resistance heat. The NE Heat Pump Accelerator adds a $650 point-of-sale incentive on top of that, available to all NH homeowners regardless of utility. A.J. LeBlanc Heating is a registered NHSaves contractor: the Accelerator discount is applied right at purchase, and we prepare and file the NHSaves rebate paperwork with you.
How long does mini split installation take?
Most single-zone installations are completed in one day. Multi-zone systems with three or four indoor units typically take two days. We handle all permits and inspections as part of the installation.
Do you service mini splits you didn't install?
Yes. We service all major brands (Mitsubishi, Daikin, Bosch, LG, and others), whether we installed them or not. Call 603-623-0412 to schedule mini split repair and service or a maintenance check.
Reviews From Southern NH Homeowners
Excellent techs polite, friendly and everything was cleaned at the end of each day. Air conditioning is working great can't wait to see how they do at the start of the heating season.
Chester and Judy SzugdaA/C Installation customerSo glad that we got a new a/c with A.J. LeBlanc Heating, especially this summer - best it has ever worked.
Lisa MoreyA/C Installation customerAfter having A.J. LeBlanc Heating do an installation of the AC mini-splits about a year and a half ago, I decided to check with them first about replacing my boiler which was 30 years old. I requested the same salesman and was glad to have the continuity of someone familiar with my needs. The technicians who came to do the boiler installation were great - one was the same who had been here with the mini-split installation, so I felt comfortable that the job would be done perfectly and I was not disappointed. I would recommend A.J. LeBlanc Heating for service anytime!
