Most AC repair calls in NYC have a specific, diagnosable cause. We find it with real equipment, explain it in plain language, and give you an honest recommendation — repair, maintain, or replace. No pressure. No guesswork.

After 30 years of NYC AC repairs, the same issues come up again and again. Here's what they are, what causes them, and how we fix them.
The most common emergency call we receive. If your system has been properly maintained, warm air is most likely a refrigerant issue. If it hasn't been maintained — there are several possibilities we need to rule out first.
As more NYC homeowners upgrade to smart thermostats, we're seeing a significant rise in calls that have nothing to do with the AC itself — and everything to do with wiring, compatibility, and settings.
Poor airflow is behind a surprising number of AC complaints — from rooms that won't cool to systems that freeze up. Sometimes it's a maintenance issue. Other times, changes were made to the space without understanding what the system was originally designed to handle.
Capacitors, contactors, and control boards are the most common electrical failures in AC systems. Most are repairable same-day if caught before they cause secondary damage to the compressor.
Water leaking from your AC unit — indoors or outdoors — is always a sign something needs attention. In NYC apartments, a drain issue can quickly become a water damage issue for the unit below.
Every AC noise has a cause — and some are significantly more serious than others. A rattling sound is very different from a grinding or squealing sound. Never ignore a new noise from your AC system.
Not all refrigerant leaks are created equal — and the right response depends entirely on the severity. Here's our honest approach, because the science matters more than the invoice.
If your system has been properly maintained and is still blowing warm air, a refrigerant leak is the most likely cause. The question is: how big is the leak?
If refrigerant is dropping slowly — say, the system needs a small top-off every year or two — an expensive leak search may not be the most economical choice. In some cases, a monitored annual refrigerant boost is the most cost-effective path, especially on older systems where a full repair may not be worth the investment.
When refrigerant is dropping fast — the system loses charge within a season or less — a refrigerant leak search is the right call. We use electronic leak detectors and UV dye to find the source, make the repair, and recharge the system correctly. Continually adding refrigerant to a large leak is expensive and environmentally irresponsible.
