Your air conditioner breaks down at the worst time. We get it. A failed AC system isn’t just uncomfortable — it’s stressful, especially in the middle of a hot Long Island summer. AJ Services has been fixing AC units across Nassau County for over 20 years. We diagnose the problem quickly and repair it right.
Most AC repairs fall into a handful of common categories. Understanding what’s happening with your system helps you decide if a repair makes sense or if replacement is smarter.
A system that won’t cool usually has one of three issues: low refrigerant (which means there’s a leak), a dirty evaporator coil that blocks heat transfer, or a failed compressor. Low refrigerant is the most common. Important: refrigerant doesn’t “run out” like gas. If the system is low, there’s a leak somewhere. Recharging without finding and sealing the leak is wasting money. We find the leak and fix it.
Short cycling — where the AC turns on and off every few minutes — often points to a capacitor failure. The capacitor is a small electrical part that starts the compressor and fan motors. When it fails, you’ll hear the system hum but it won’t actually start cooling. A failed capacitor is usually a fast, affordable repair. We also check thermostats and airflow problems, which can cause the same symptom.
Ice forming on the refrigerant line or indoor unit is a sign of restricted airflow or low refrigerant. Running the system with ice buildup can damage the compressor, so this needs attention soon. Water leaking inside usually means a clogged condensate drain line — the pipe that carries humidity out of your home. We clean the line and treat it to prevent future blockages.
We start with a full diagnostic. Our technicians check refrigerant pressure, electrical connections, capacitor health, motor function, and overall system performance. We listen to how the system runs and inspect the coils and drain line. After we understand the problem, we give you an honest assessment: can we repair it affordably, or is replacement a smarter choice?
On many repairs — especially capacitor failures, refrigerant leaks, and compressor issues — we can often complete the work the same day. We’re licensed and insured in New York and we back our work with a warranty. If you need emergency service on nights or weekends, we’re available 24/7.
AJ Services repairs all major AC brands: Lennox, Carrier, Trane, York, Rheem, and others. We also service mini split systems and ductless units.
We’ve been here for over 20 years. We’re based in Bellmore and we know Long Island homes — from old capes and ranches built before AC was standard to newer colonials and high-velocity systems. We understand the climate. Long Island summers are hot and humid. High humidity actually makes the problem worse because your AC has to work harder to pull moisture out of the air. A system that’s leaking refrigerant or has a dirty coil won’t handle that humidity, and your house stays uncomfortably damp.
We’re also honest about economics. If your compressor fails on a 14-year-old system, we’ll tell you that replacement is likely smarter than a $1,200 repair. We don’t push repairs that don’t make sense. We want to help you make the right choice for your home.
Why is my AC running but not cooling?
The most common causes are low refrigerant (there’s a leak), a dirty evaporator coil, or a failed compressor. We diagnose which one during a service call. Low refrigerant is easiest to fix if we find the leak.
Why does my AC keep turning on and off?
Short cycling usually means the capacitor has failed or the thermostat is malfunctioning. A bad capacitor makes the system hum but won’t start. A failed thermostat sends wrong signals. Both are usually quick repairs.
What does it mean when my AC is leaking water?
The condensate drain line — which carries humidity out of your home — is clogged. This is common on Long Island because algae and debris build up in the line. We clean and flush it, and we apply a tablet to prevent future blockages.
Can you repair my AC the same day?
For many repairs — capacitor failures, refrigerant leaks, compressor replacements, and drain line clogs — yes, we finish the same day. Call us at 516-807-8700 to schedule. We also have 24/7 emergency service if your AC breaks after hours.
When is it better to replace than repair?
If your system is 12+ years old and the repair costs more than one-third of a new system, replacement usually makes more sense. A failed compressor on an old system is often a replacement trigger. We’ll give you an honest recommendation based on the age, efficiency, and repair cost.
How much does AC repair cost on Long Island?
Repairs range from $200-$500 for simple fixes like a capacitor or drain line cleaning, to $800-$1,500 for refrigerant leaks or motor repairs. We’ll give you an estimate before we start. Call for a quote: 516-807-8700.
