As mid-summer heat intensifies across Long Island, homeowners from Huntington to East Hampton are relying on their air conditioners more than ever.

But what happens when your AC starts to show signs of stress?


At Absolute HVAC, we help customers in Smithtown, Islip, Patchogue, Riverhead, Babylon, and beyond recognize the early warning signs of AC trouble—before it turns into a full system breakdown during a heatwave.


🚨 Don’t Ignore These Common AC Warning Signs


1. Warm Air Coming from Vents

If your AC is blowing warm or room-temperature air, it could be a refrigerant leak, compressor issue, or thermostat problem. This is one of the top calls we receive from Glen Cove, Port Jefferson, and Bay Shore homeowners.


2. Weak Airflow

Struggling to cool down rooms in your Bellport or Hauppauge home? Weak airflow is often caused by blocked ducts, dirty filters, or a failing blower motor.


3. Strange Noises

Banging, buzzing, or screeching noises are not normal. These sounds can signal loose parts, broken fans, or electrical issues. Absolute HVAC offers fast diagnostics and repairs across Nassau and Suffolk County, including Babylon and Smithtown.


4. Unusual Smells

A burning, musty, or chemical odor coming from your HVAC system is a major red flag. This can indicate mold in the system or electrical components overheating.


5. Frequent Cycling On and Off

Short cycling (when your system turns on and off repeatedly) leads to high energy bills and system wear. This is common in older AC units we service in Islip, Patchogue, and Riverhead.
