When summer heat hits New Jersey, a working air conditioner is more than a convenience, it’s essential. But like any mechanical system, AC units wear down, and small issues left unchecked can morph into major breakdowns. At Temprite, we’ve seen it all: calls after hours, urgent repairs, and homeowners sweltering through nights.

This article will equip you with the top five warning signs that your AC needs immediate attention, how to interpret what they might mean, and when it’s time to call your trusted local experts at Temprite (Freehold, NJ, 732‑946‑7600). Catching problems early can save you money, stress, and the risk of being without air conditioning during a heatwave.
1. Weak or Inconsistent Airflow (or Warm Air from Vents)
Perhaps the most obvious—but often ignored—sign is poor airflow. If your AC is running but the air coming out of your vents is weak or lukewarm (rather than cold), that’s a red flag.
Common causes and what they suggest:
- Clogged or dirty air filter — When filters are blocked, they restrict airflow, forcing your system to struggle.
- Ductwork leaks or blockages — Holes, separated duct joints, or crushed flexible ducts reduce the volume of cooled air reaching rooms.
- Compressor or blower motor problems — If these components are failing, they won’t be able to push cool air adequately.
- Low refrigerant level — Without sufficient refrigerant, the system can’t absorb heat properly, so the air you feel is not fully “conditioned.”
- Frozen evaporator coil — Ice buildup on coils can choke airflow until it thaws, making your AC ineffective.
In a normal AC system, airflow should feel strong and consistent across all vents (after filters and supply registers are clean). If some rooms are warmer than others or vents feel like weak breezes, have someone check the system.
2. Strange Noises or Unusual Sounds
Your AC shouldn’t make a racket. When it does, something’s off.
Sounds to listen for and what they often mean:
Sound / Noise | Possible Cause | Urgency |
---|---|---|
Grinding / screeching | Worn motor bearings or failing blower | High — can lead to motor failure |
Banging / clanking | Loose parts, broken components, fan hitting something | High — could cause internal damage |
Hissing / bubbling | Refrigerant leak or pressure leak | High — refrigerant leaks damage performance |
Buzzing / humming | Electrical issues, short circuits, relay failing | High — risk of electrical failure |
Clicking / popping | A hard start, relay switching, compressor struggling | Moderate to high — may worsen quickly |
Even a persistent squeal or click deserves inspection. A sound repeated each cycle is a cry for help from your system—and the earlier you respond, the better.
3. Frequent Cycling (Short Cycling)
An AC that turns on and off repeatedly without completing full cooling cycles is “short cycling.” This is harmful, inefficient, and a clear warning sign.
What causes short cycling?
- Thermostat miscalibration or failure — If the thermostat misreads the temperature, it may shut off the system prematurely.
- Oversized AC unit — A system too large for the home may cool rooms quickly and shut off before properly dehumidifying or maintaining balance.
- Low refrigerant or pressure issues — The system may struggle to complete a cycle, stopping early.
- Clogged air filter or blocked airflow — The system overheats, forcing a shutoff before a full cycle completes.
- Control board or electrical faults — Short circuits or erratic signals can cause cycles to end prematurely.
Short cycling is more than annoying — it accelerates wear and tear, increases your electricity consumption, and raises the chance of a component failing prematurely. If you see this happening, call for diagnosis.
4. Spike in Energy Bills (Without Change in Usage)
If your monthly electric or HVAC bill takes a sudden jump and you haven’t changed your usage habits, something is causing your system to work harder than it should.
Why your bills might jump:
- Dirty or clogged components causing higher resistance and inefficient operation
- Refrigerant leakage or low refrigerant levels
- Failing compressor or circuit board issues that cause inefficiency
- Duct leaks or poor insulation that waste cooled air
- Worn parts causing drag or inefficiency
Because HVAC use is a major portion of summer energy bills, a 10–20 % increase without explanation is a strong indicator that you need an inspection. Temprite technicians can run diagnostic tests to find the culprit and fix it before the next billing cycle hits your wallet.
5. Water Leaks, Ice Formation, or Moisture Around the Unit
Water or ice where it doesn’t belong spells trouble. Moisture inside or outside your system often hides more serious malfunctions.
What to watch for:
- Pooling water or dripping — likely from a clogged condensate drain or clogged drain line.
- Ice or frost on coils or refrigerant lines — points to low refrigerant or limited airflow.
- Moisture or dampness in the air handler or duct space — could mean leaks or improper drainage.
- Oily residue or traces around refrigerant lines — could be refrigerant leaks, which must be handled by a licensed technician.
If you see any of these, immediately shut off the AC (or switch to “Fan only”) to prevent further damage, then call Temprite for a prompt check.
Why Acting Immediately Matters
Let’s be honest: ignoring early warning signs is risky. Here’s what can happen if you wait:
- A small repair can turn into a major component failure (compressor, fan motor, control board)
- You may get stuck without AC on the hottest days
- Repair costs can balloon
- You may inadvertently damage ductwork, electronics, or cause mold/moisture problems
- Your system’s lifespan can shorten
Temprite’s philosophy is: prevention and prompt response beat emergency replacements any day. Our emergency response team in Freehold, NJ is available 24/7 for residents and businesses. We believe in doing things right the first time — diagnosing carefully, proposing only necessary repairs, and treating your home or facility as we would our own.
How to Respond If You See One (or More) of These Signs
Here’s a practical step-by-step guide on what to do if your AC shows warning signals:
- Check the basics first
- Replace or inspect your air filter
- Clear debris from around outdoor condenser
- Ensure thermostat settings are correct
- Reset or check circuit breakers
- Monitor behavior over 24 hours
- See whether the issue is constant or intermittent
- Note noises, leaks, airflow, or any patterns
- Turn off the system if you see refrigerant leaks, ice, or water pooling
- Let the unit thaw and stabilize
- Don’t run it further until cleared
- Call Temprite ASAP
- Provide us with observed signs, model, and symptoms
- Schedule a professional inspection
- Ask about our maintenance plan
- Regular maintenance prevents many of these issues
- Our team can include seasonal check-ups to keep your system in top shape
Quick Comparison: “Repair Now” vs “Later”
Here’s a simple table to help you decide when to act quickly versus when to monitor:
Symptom / Sign | Recommended Urgency | Potential Risk if Delayed |
---|---|---|
Weak airflow / warm air | High | Compressor damage or system strain |
Strange noises | High | Motor or component failure |
Short cycling | High | Excess wear, inefficiency |
Bill spike | Medium–High | Escalating costs, hidden damage |
Leaks / ice / moisture | Very High | Water damage, mold, refrigerant issues |
Whenever you see two or more of these signs together, do not wait — call for inspection immediately.
