Top 10 Signs Your AC Needs Immediate Repair This Summer
When the Florida heat hits hard, your AC system becomes your home’s lifeline — but what if it starts sending distress signals?
From unusual noises to skyrocketing energy bills, there are clear signs that your air conditioning unit needs immediate attention. Ignoring these can lead to bigger problems and higher costs — not to mention a whole lot of discomfort.
At Pro-Tech Air, we help homeowners in Royal Palm Beach, Wellington, West Palm Beach, and surrounding areas stay cool, calm, and protected from AC breakdowns. Here are the top 10 warning signs your system might be on the brink.
1. Unusual Noises
Grinding. Squealing. Banging. If your AC starts making any of these noises, it’s time to act.
Grinding sounds may indicate loose internal parts like screws, fan blades, or motor components.
Squealing often signals a belt or motor issue.
Banging can mean debris is obstructing the fan.
Don’t wait. These noises are early warning signs — and the longer you leave them, the more damage they can cause.
2. Weak Airflow
Poor airflow can be caused by:
Blocked or obstructed vents
Dirty filters reducing system efficiency
Leaky or damaged ductwork
This often leads to uneven cooling across your home and forces your system to work overtime — a major concern for energy-conscious families across Palm Beach Gardens and Loxahatchee.
3. Warm Air from Vents
Warm air could be a sign of:
A refrigerant leak
A malfunctioning compressor
Airflow restrictions or blocked coils
If your AC is blowing warm air while your thermostat is set to cool, it's time to schedule a service call.
4. Frequent Cycling
Does your system constantly turn on and off? That’s known as short cycling, and it could point to:
A faulty thermostat
Low refrigerant levels
Electrical issues disrupting power flow
Short cycling increases wear on your system, reduces efficiency, and almost always leads to premature failure if left unchecked.
5. High Humidity Indoors
A functioning AC should help regulate indoor humidity. If it feels muggy inside your Royal Palm Beach home, it may be due to:
A sensor malfunction
Leaky or clogged ductwork
Low refrigerant or an aging unit struggling to keep up
High humidity doesn’t just feel uncomfortable — it can lead to mold growth and long-term damage.
6. Water Leaks Around Your AC
Water pooling around your unit typically signals:
A clogged condensate drain
A refrigerant leak
Damaged drain lines or overflows
Left alone, this can cause water damage, corrosion, or even electrical hazards.
7. Foul or Musty Odors
Unpleasant smells coming from your vents? Possible causes include:
Mold growth in the ducts or coils
Dirty air filters causing stagnant airflow
Burning smells from electrical issues
Prompt action can prevent health risks, especially for families with allergies or respiratory issues.
8. Sudden Spikes in Energy Bills
Have your utility bills jumped even though your usage hasn’t? That’s often a sign of:
System inefficiency due to aging parts
Dirty filters straining airflow
Insulation or duct leaks causing cool air loss
This issue is common across homes in Boca Raton, Westlake, and older areas of Lake Worth.
9. Thermostat Issues
Your thermostat is the brain of your system. Common problems include:
Incorrect temperature readings
Blank or flickering display
Sensor failure causing erratic behavior
A faulty thermostat can cause the system to overcool or undercool, wasting energy and leaving you uncomfortable.
10. Ice Buildup on Coils or Lines
Seeing ice on your indoor unit or refrigerant lines? Possible causes:
Low refrigerant levels
Blocked airflow from dirty filters or closed vents
Damaged coils
Ice can reduce system performance and eventually lead to compressor failure if not addressed quickly.

Frequently Asked Questions
Q: How often should I schedule maintenance?
We recommend twice yearly service (pre-summer and pre-winter). Replace filters every 1–3 months.
Q: Can power surges damage my AC?
Yes. Surges can fry components. Consider installing a whole-home surge protector.
Q: Is an energy-efficient AC worth it?
Absolutely. It reduces bills, increases comfort, and lowers your carbon footprint.
Q: How do I know if my AC is the right size?
An improperly sized unit leads to short cycling or weak cooling. We can perform a load calculation and duct inspection to verify.
Q: Are there any DIY checks I can do?
Yes — clean/replace filters, inspect vents, adjust your thermostat, and clear debris around your outdoor unit. But leave refrigerant and electrical work to the pros.
