Air conditioning repair for Long Island homeowners — Nassau County & Western Suffolk
Supported central AC, ductless, and heat-pump cooling systems across Nassau County with written scope, pricing, and scheduling confirmed before authorized work.
A few safe observations help dispatch confirm equipment capability and help the technician prepare for the visit.
Note the thermostat display, system make and model, and when cooling stopped.
Check whether the filter is visibly blocked and whether the breaker has tripped.
If the breaker trips again after one reset, leave it off and report that condition.
Turn the system off and call if you see ice, smell burning, hear grinding, or find water near electrical components.
AC repair begins with the thermostat call, airflow, indoor and outdoor equipment, electrical components, drainage, and refrigerant-circuit observations appropriate to the system. The diagnosis and written repair price are reviewed before authorized work.

We do, across Nassau County and Western Suffolk. Calls reach a live dispatcher 24/7, including nights and weekends, and dispatch confirms the next open arrival window for your address before you commit to anything.
The residential diagnostic is $199 and it buys you a written cause plus a fixed repair price before any work starts. Most common repairs land between $200 and $700 in parts and labor; you approve the number first, and larger jobs come with a repair-versus-replace comparison.
Central air conditioning, heat pumps in cooling mode, and ductless mini splits, including capacitor, contactor, compressor, refrigerant-leak and drain-line faults. Give us the make, model, thermostat reading and any error code when you call so the right parts are on the truck.
Yes. No-heat, no-cool, water leaks and gas odors are treated as emergencies, dispatched 24/7. Shut the system off, then call (516) 259-1191 and dispatch confirms current availability for your street.

Central air, heat pump cooling, and ductless mini-split repair with a $199 diagnostic, a written fixed price before work, and ZIP-code coverage confirmed when you call.
Home+ Air & Heat repairs residential cooling across Nassau County and Western Suffolk from our Jericho shop, including Hicksville, Garden City, Levittown, Massapequa, Syosset, Farmingdale, and the Huntington and Islip areas. Coverage is confirmed by ZIP code when you call, and the diagnostic fee and repair price are stated before any work is authorized.
Both. Central split systems, heat pumps running in cooling mode, and ductless mini splits are all supported. Central AC work covers capacitors, contactors, blower motors, control boards, condensate drains, coils, and refrigerant-circuit faults; ductless work adds indoor head boards, sensors, and line-set and drain issues specific to wall-mounted units.
No. Service (a tune-up) is planned maintenance: cleaning, electrical checks, refrigerant and airflow verification on a system that still runs, priced as a flat visit. Repair starts with a $199 diagnostic on a system that is not cooling correctly, then a written fixed price for the fix. If you are unsure which you need, describe the symptoms on the phone and dispatch books the right visit.
The diagnostic is $199, and the common repairs on this page run $175–$900 depending on the failed part. Capacitor and contactor work sits at the low end, blower motors and breaker-tripping electrical faults in the middle, and sealed-system or compressor work at the top. Refrigerant, parts availability, and equipment age are the three factors that move the number most.
We cover Western Suffolk, including the Huntington, Babylon, and Islip areas, and confirm your specific ZIP code before booking rather than promising blanket county coverage. Eastern Suffolk and the East End are outside the service radius. Nassau County is covered in full.
Calls are answered 24/7 and dispatch confirms the current appointment window or emergency ETA for your address — no fixed time guarantee is made. If water is threatening electrical equipment or you can see ice on the coil or line set, shut cooling off at the thermostat, leave the ice alone, and call for guidance.
Replacement usually wins when the system is past roughly 12–15 years, uses R-22, needs a compressor or sealed-system repair, or when the repair quote approaches a third of replacement cost. The diagnostic gives you both numbers in writing, and a repair stays available as the short-term option if you would rather get through the season first.
