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.
Warning signs
Common signs you need ac repair
Catching these early prevents emergency calls and bigger repair bills down the road.
Warm air from vents
Often a refrigerant leak, failed compressor capacitor, or iced-over evaporator coil.
AC won't turn on
Usually a tripped breaker, blown low-voltage fuse, bad thermostat, or failed contactor.
Ice on the lines
Restricted airflow (dirty filter, blocked return) or low refrigerant — turn the system off and call.
Loud humming or buzzing
Failing capacitor, contactor chatter, or a fan motor on its last leg.
Water around the air handler
Clogged condensate drain — common on Long Island in humid July weather.
Short cycling
Oversized system, dirty coil, low refrigerant, or a failing thermostat.
Common causes
What's typically going wrong
01
Refrigerant leaks
Aging coils and line-set fittings develop pinhole leaks. We pressure-test, locate, repair, and recharge to factory spec.
02
Failed capacitors
The #1 summer failure on Long Island. A $30 part causes the compressor to refuse to start. Replaced in under 20 minutes.
03
Dirty coils & filters
Poor airflow leads to ice-up, frozen coils, and blower strain. We clean and restore proper static pressure.
04
Electrical faults
Burnt contactors, loose lugs, and degraded relays. We test every connection during service.
05
Coastal corrosion
Salt air from the Sound and Atlantic eats outdoor coils faster than inland. Annual cleaning is critical.
Decision guide
Repair or replace?
Repair if…
System is under 10 years old, repair is under $1,500, and the rest of the unit is healthy.
Replace if…
Unit uses R-22 refrigerant, is 12+ years old, has had 2+ major repairs, or the compressor has failed.
