Why Brookside
Installed and Serviced Since 1988
Brookside Heating & Cooling has installed and serviced ductless systems across Southern New Hampshire since 1988. We handle the load calculation, the system design, the install, and the service after.
Load calculation and design
We measure the space, account for insulation, windows, and orientation, and size the equipment to match.
Cold-climate rated
Today's cold-climate systems are rated to produce real heat well below zero through Manchester's coldest stretch.
Trusted brands
We install systems from Mitsubishi Electric, LG, and other manufacturers we stand behind.
Straight answers
We'll tell you straight whether ductless is the right call for your home — sometimes it isn't, and we'll say so.
How It Works
Single-Zone vs. Multi-Zone Systems
A load calculation tells us which one fits your home.
Single-zone systems
One outdoor unit connects to one indoor unit, fixing a specific problem like an addition, a home office, or a bedroom that never gets comfortable.
Multi-zone systems
Several indoor units, usually two to five, run off one outdoor unit to cover a whole house or a handful of rooms that each need their own control.
Load calculation
We measure the space, account for insulation, windows, and orientation, and size the equipment to match — oversizing a system wastes energy and never dehumidifies properly.
Frequently Asked Questions
How much does a ductless mini-split cost to install in New Hampshire?
Cost depends on the number of zones, the equipment tier, and how complicated the install is, with a single-zone system running considerably less than a multi-zone whole-home setup. Brookside Heating & Cooling gives you a free, firm quote after an in-home assessment, and available rebates and financing come off that number, so ask about current specials when you schedule.
Can a mini-split heat my whole house?
In many Manchester homes, yes, with a properly sized multi-zone system, though it depends on your layout, your insulation, and how open the floor plan is. Brookside Heating & Cooling will tell you honestly whether ductless alone will do the job or whether a hybrid setup makes more sense.
How long does a ductless installation take?
Most single-zone installs finish in a day. Brookside Heating & Cooling notes that multi-zone systems usually take two to three days, depending on how many indoor units are going in and how the line sets have to be routed.
How long do ductless mini-splits last?
With regular maintenance, expect 15 to 20 years. Brookside Heating & Cooling points out that's as good as or better than a central system, largely because there's no ductwork degrading alongside the equipment.
Are mini-splits noisy?
Indoor units run quieter than a normal conversation. Brookside Heating & Cooling explains that the compressor and fan that make real noise sit in the outdoor unit, away from your living space.
Do I still need a furnace if I install a ductless heat pump?
Not always. Brookside Heating & Cooling says many Manchester homeowners run a cold-climate ductless system as their primary heat and keep existing heating equipment as backup for the coldest days, while others go fully ductless, and we'll model both against your actual home before you decide.
