Half of Queens has no ductwork and never will. Prewar six-stories in Jackson Heights, attached brick houses in Astoria, railroad apartments in Sunnyside, finished attics in Forest Hills. A ductless mini-split puts a quiet wall-mounted head in each room, runs a line set to one outdoor unit, and heats and cools without opening a single wall.

Queens HVAC Co installs and services ductless systems from Astoria across the borough, same week in most seasons. Call (929) 702-2132 or request a free estimate.

Wall-mounted mini-split in a home office

Ductless Mini-Split Installation Built for Queens Homes and Buildings

Line set routing is the whole install in a Queens building. A 3-inch hole through brick, line hide down the facade or up a light well, an outdoor unit on a wall bracket, a roof, a balcony or a backyard pad. Co-ops want the drawing before they say yes, and we draw it.

Condensate has to go somewhere. Gravity drains to the outside where the wall allows, a condensate pump in the head where it does not. Cheap pumps fail in August. We use the ones that do not.

Head sizing per room beats one big head in the hallway. A 9,000 BTU head in a 12-by-14 bedroom, a 12,000 in the living room, a 6,000 in the office. Oversized heads short cycle and leave rooms clammy.

Ductless Systems That Fit Queens Properties

Single-zone wall units for one room, a home office or a basement rental. Multi-zone systems with two to five heads on one outdoor unit for whole-apartment and whole-house coverage. Ceiling cassettes and slim-duct units for rooms where a wall head will not work. Cold-climate hyper-heat models that heat through winter and qualify for rebates under Heat Pump Installation & Repair. Mitsubishi, Daikin, Fujitsu and LG, matched to the building and the budget. Deep cleaning and repair on existing systems that have gone musty or stopped cooling.

What Affects the Cost of Ductless Mini-Split Installation in Queens

  • Number of zones and the BTU rating per head.
  • Line set length and routing: a 15-foot run and a 60-foot run up a light well are different jobs.
  • Outdoor unit placement: backyard pad, wall bracket, or a roof that needs a lift.
  • Electrical: a dedicated circuit versus a panel upgrade.
  • Cold-climate rating and the rebates that come with it.

Local Conditions Our HVAC Contractors Work Around in Queens, NY

  • Brick, block and plaster walls that take a core drill, not a hole saw.
  • Co-op facade rules on line hide color and outdoor unit placement.
  • Light wells and air shafts as the only line set route in prewar buildings.
  • Landmarked blocks in Jackson Heights and Forest Hills where the front facade is off limits.

Preventing and Solving Common Mini-Split Problems

  • Musty smell: dirty blower wheel and coil; fixed by a deep clean.
  • Water dripping from the head: clogged drain line or a failed condensate pump.
  • Head blowing warm in summer: low charge from a flare leak, which gets torqued and tested at install.
  • One zone dead: communication wiring or a board, diagnosed on the first visit.

What to Expect When You Hire Our Queens HVAC Company

  • A line set drawing the co-op can approve.
  • Heads sized per room, with the BTUs in the proposal.
  • Flare joints torqued to spec and nitrogen tested, because flare leaks are the number one mini-split callback.
  • A yearly deep clean through HVAC Maintenance & Tune-Ups so the heads stay fresh.

Where ducts are possible and the house is large, we show the AC Installation number too. Sometimes it wins.

"A ductless head is only as good as the hole it comes through. We drill once, straight, and sleeve it."
