Outdoor central AC condenser next to a building

Central AC + Furnace

What it is: A complete central system — cooling in summer, forced-air heating in winter — sharing the same ductwork.

How to recognize it: An outdoor AC unit plus a tall indoor furnace cabinet (basement or closet) feeding vents throughout the home.

How it works: The furnace heats the air and the AC coil cools it; one blower and one duct system handle both seasons.

What moves the price: Same as central AC, plus the furnace's efficiency and its venting.

Outdoor central AC condenser serving a ducted cooling system

Central AC only

What it is: Whole-home cooling delivered through ductwork from an outdoor condenser and an indoor coil/air handler.

How to recognize it: A large outdoor unit plus vents (registers) in most rooms, fed by an indoor cabinet in a closet or basement.

How it works: The air handler pushes cooled air through the ducts; the outdoor unit releases the heat outside.

What moves the price: System size (home size), the condition of your ducts, efficiency rating, removing the old system, and permits.

Heat Pump

What it is: One all-electric system that both heats and cools by moving heat instead of burning fuel — very efficient.

How to recognize it: It looks like an AC's outdoor unit but runs in winter too; cold-climate models are often labeled "hyper heat."

How it works: It runs the refrigeration cycle in reverse to pull heat from outside air, even when it's cold out.

What moves the price: Capacity, ducted vs. ductless, cold-climate spec, and whether your electrical panel needs an upgrade.

Ductless Mini-Split

What it is: A ductless system — a small outdoor unit feeds one or more indoor "heads" through slim refrigerant lines, and each head heats and cools its own room.

How to recognize it: A slim unit mounted high on a wall (or flush in the ceiling), plus a small fan unit outside. No vents, no ducts.

How it works: Refrigerant carries heat between each indoor head and the outdoor unit; every head has its own remote.

What moves the price: Number of heads/zones, how far the refrigerant lines run, wall vs. ceiling-cassette heads, and any electrical panel work.

Furnace only

What it is: A forced-air heater (gas or electric) that warms air and pushes it through ducts. (We service furnaces, not boilers.)

How to recognize it: A tall metal cabinet in a basement, closet, or utility space with a flue pipe; it blows warm air through the vents.

How it works: It heats a metal heat exchanger and a blower sends the warm air through your ducts.

What moves the price: Efficiency (AFUE), size, gas vs. electric, venting changes, and removing the old unit.

PTAC (through-wall)

What it is: A self-contained unit that mounts through an outside wall and handles one room — common in apartments, hotels, and additions.

How to recognize it: A rectangular unit under a window or in the wall, with a grille on the outside. No separate outdoor unit and no ducts.

How it works: Everything is in one box that vents through the wall, with the controls on the unit itself.

What moves the price: Reusing an existing wall sleeve vs. cutting a new opening, how many units, and electrical.

How big is the space?

Larger spaces need larger equipment and more labor, so this is the plain-language sizing input.

How many rooms or zones need cooling or heating?

Mini-split pricing rises mostly with the number of indoor heads, room zones, and line-set routing.

How many PTAC units?

PTAC pricing scales by unit count and whether an existing wall sleeve can be reused.

Is this new or replacing an existing system?

Replacement work can add removal, disposal, patching, and connection changes.

Do you have existing ductwork?

New ducts can be a major line item because they add materials, access work, and labor.

Sheet-metal HVAC ductwork running through an unfinished ceiling — This is ductwork: rigid metal trunk lines and branches above ceilings, in basements, or mechanical spaces.

What type of building is it?

NYC access, building rules, permits, and board approvals can change labor and scheduling.

Add indoor-air-quality upgrades?

These are optional add-ons. They improve filtration, humidity, or cleaning, and each selected item adds to the estimate.

Wall-mounted fresh-air ventilation and air-quality equipment — Fresh-air and IAQ equipment can be wall-mounted near ductwork or mechanical rooms.

Air purifierWhole-system filtration upgrade. HumidifierBetter winter comfort and humidity control. UV lightCoil and air-stream UV treatment. Duct cleaningCleaning for existing duct systems. No add-onsSkip upgrades for this estimate. Not sureWe will leave add-ons out for now.

When do you want this handled?

What ZIP code is the project in?

ZIP helps localize NYC labor, access, and travel assumptions.

Which marine AC system type?

Not sure which system you have? See what each looks like →

Marine — Self-contained

What it is: A compact, all-in-one marine AC unit that cools one zone, sized for smaller boats.

How to recognize it: A single boxy unit tucked into a locker or the bilge, with a seawater hose and a short duct run.

How it works: Instead of outside air, it uses seawater to carry heat away; one unit serves one area.

What moves the price: Boat length, number of units, seawater plumbing, and how tight the install space is.

Marine — Chilled-water

What it is: A central marine system — one chiller cools water/glycol that's piped to air handlers in each cabin. For larger vessels.

How to recognize it: A central chiller in the engine room with insulated pipe runs feeding multiple cabin air handlers.

How it works: The chiller cools a loop; each cabin's air handler uses that loop to condition its space.

What moves the price: Boat length, number of cabins/zones, pump and piping condition, and equipment layout.
