AC Repair across Nassau & Western Suffolk
Long Island HVAC Repair usually provides same-day AC repair across Nassau County and Western Suffolk for central air, ductless mini-splits, and heat pumps. Most no-cool calls — failed capacitors, refrigerant leaks, frozen coils, contactor issues — are diagnosed within 30 minutes and repaired on the first visit with flat-rate pricing and a 1-year warranty.
When your AC quits in a Long Island heat wave, every hour matters. Our techs arrive in fully stocked vans ready to repair refrigerant leaks, failed capacitors, frozen coils, and electrical faults on most major brands.
Common signs you need ac repair
Catching these early prevents emergency calls and bigger repair bills down the road.
Often a refrigerant leak, failed compressor capacitor, or iced-over evaporator coil.
Usually a tripped breaker, blown low-voltage fuse, bad thermostat, or failed contactor.
Restricted airflow (dirty filter, blocked return) or low refrigerant — turn the system off and call.
Failing capacitor, contactor chatter, or a fan motor on its last leg.
Clogged condensate drain — common on Long Island in humid July weather.
Oversized system, dirty coil, low refrigerant, or a failing thermostat.
What's typically going wrong
Aging coils and line-set fittings develop pinhole leaks. We pressure-test, locate, repair, and recharge to factory spec.
The #1 summer failure on Long Island. A $30 part causes the compressor to refuse to start. Replaced in under 20 minutes.
Poor airflow leads to ice-up, frozen coils, and blower strain. We clean and restore proper static pressure.
Burnt contactors, loose lugs, and degraded relays. We test every connection during service.
Salt air from the Sound and Atlantic eats outdoor coils faster than inland. Annual cleaning is critical.
Repair or replace?
System is under 10 years old, repair is under $1,500, and the rest of the unit is healthy.
Unit uses R-22 refrigerant, is 12+ years old, has had 2+ major repairs, or the compressor has failed.
What's included in your AC diagnostic visit
Every visit follows the same documented checklist — so nothing gets skipped and you get a written report at the end.

AC Repair questions, answered
Nassau and Western Suffolk addresses often see same-day service when called before noon. We have 24/7 emergency dispatch for complete no-cool situations.
Yes — a flat diagnostic fee that's fully waived if you approve the repair. You always see the repair price in writing before any work begins.
Carrier, Trane, Lennox, Rheem, Goodman, Bryant, Mitsubishi, Daikin, York, American Standard, and most other major manufacturers.
Shut the system off to prevent water damage and call us. It's almost always a clogged condensate drain line, which we can clear in one visit.
Frozen coils are caused by restricted airflow (dirty filter or blocked return) or low refrigerant. Both are common on Long Island and easy to fix.
If your system is 12+ years old, uses discontinued R-22 refrigerant, or the repair is over $1,500, replacement usually delivers better long-term value.
Yes — we repair Mitsubishi, Daikin, Fujitsu, LG, and Samsung mini-split systems including communication errors, refrigerant issues, and outdoor unit faults.
Every repair includes a 1-year warranty on parts and labor. New parts also carry the manufacturer's standard warranty on top.
Most Long Island AC repairs land between $185 and $650 all-in. Capacitors run $185–$320, contactors $190–$340, blower motors $550–$1,200, and refrigerant leak repair with a recharge $450–$1,400 depending on refrigerant type. You get the flat-rate number in writing before we start.
Emergency and after-hours calls carry a higher dispatch rate, and we tell you the exact figure on the phone before we roll a truck. There are no surprise surcharges added after the work is done.
Waiting usually costs more. A system running low on refrigerant or with a weak capacitor draws high amps and stresses the compressor — the single most expensive part in the system. A $250 repair in July often prevents a $3,000 compressor failure in August.
Yes, we still service R-22 systems, but the refrigerant is no longer produced and now costs several times what R-410A does. On any significant R-22 leak we show you the repair cost and the replacement cost side by side so you can decide with real numbers.
Plan on 60–90 minutes total: about 30 minutes to diagnose and test, then the repair itself. Roughly 85% of our calls are finished on the first visit because common parts ride on every truck.
