More about Nassau

A ductless system is the least intrusive way to add cooling to a house with no ducts, and a central AC makes sense where a forced-air furnace already moves the air. Either way, the unit is sized to the rooms it serves.

Representative work in the Nassau neighborhoods we serve.

Nassau

Found a leaking coil on a young Nassau AC that kept freezing, and noted that undersized ductwork and too little return air would keep causing problems.

Nassau

Diagnosed a Nassau AC and furnace blowing a control fuse: a power surge had damaged the control board, which then affected the gas valve, and pricing was needed for a new contactor and valve.

Nassau

Replaced a thermostat with a loose internal connection on a Nassau oil furnace and found a mini-split nearly empty of refrigerant; the owner chose to wait until spring to try recharging.

AC repair in Nassau: ductless, central air and the yearly check

A hum without a start, a ductless install and the yearly check are three cooling topics worth knowing before you call.

  • Hum but no start

    An outdoor unit that hums and never starts is an AC repair call; switch it off first.

  • Ductless installs

    Houses without ducts take ductless well, and AC installation covers central systems where ducts already exist.

  • Yearly check

    A spring check finds a weak part early; the cooling installation cost guide helps if replacement comes up.

Questions we hear

FAQs about cooling in Nassau

Straight answers from the team that does the work. Still unsure? Call and a real dispatcher picks up.

Nassau-area AC repair starts at our own shop in town, with technicians for central air and ductless mini-splits. Call Monday to Friday, 7:30am to 6pm, or book online. Same-day service is offered within business hours when the schedule allows.

Yes. Ductless heads suit homes without ductwork, with a thin line set through the wall and no demolition. Multi-head systems cool several rooms from one outdoor unit. The mini-split installation page has the details.

Not with a conventional central AC, which needs ducts. Ductless heads or a small-duct system are the options, and ductless is usually simpler. We can start with the bedrooms or the main floor and add more heads later.

Add central AC when the house has a forced-air furnace and decent ducts, since the cooling coil can share them. Choose ductless when there are no ducts or when only some rooms need cooling. The central AC versus ductless article compares them.

Same-day service is offered within business hours when the schedule allows. Phone early on a hot day, since the office opens at 7:30am. Nights and weekends are not on the schedule. If the unit hums, trips the breaker or blows warm air, say so; it shapes the visit.

Once a year, ahead of summer, is the usual advice. The visit takes in the coil, the outdoor unit, the refrigerant charge and the drain. The maintenance plan schedules it. Our spring AC checklist lists the first checks.

Ice on the coil usually means restricted airflow, from a dirty filter or a failing blower, or low refrigerant from a leak. Turn the AC off and let it thaw before calling. The AC freezing up note explains the causes.

A hum without a start usually means the start capacitor has failed, or the contactor is worn or the compressor is seized. The capacitor is a common, inexpensive part to replace. Switch the unit off at the thermostat and call, because running a humming compressor can damage it.

Often yes, because it avoids cutting ducts into the structure. A ductless heat pump can also heat the shoulder seasons. The decision turns on how many rooms you want conditioned; see heat pump versus furnace for the broader comparison.

We do. Heads that leak, error codes and outdoor units that will not run are all mini-split repair calls, and having the model name ready helps the technician plan.
