Why Is My AC Running But Not Cooling? | Florida Comfort Systems Naples, FL
If you live in Naples, Florida, you know how much we depend on our air conditioning systems to survive the heat and humidity. But what happens when your AC is running but not cooling your home? This is one of the most common questions our team at Florida Comfort Systems receives—and it can be both frustrating and costly if left unresolved.
Let’s break down the most common reasons your AC may be blowing warm air and what you can do about it.
1. Dirty or Clogged Air Filters
A dirty filter restricts airflow, causing your system to work harder while cooling less effectively. In Naples, where AC systems run almost year-round, filters should be changed every 1–3 months for peak performance and better indoor air quality.
2. Low Refrigerant Levels
Refrigerant is what your AC uses to cool the air. If there’s a leak or levels are low, your system can’t keep up with demand. This is not a DIY fix—only a licensed HVAC technician can recharge refrigerant and repair leaks safely.
3. Dirty Coils
Over time, your AC’s evaporator and condenser coils collect dust and grime, making it harder to absorb and release heat. Professional coil cleaning during routine maintenance keeps your system efficient and prevents cooling problems.
4. Thermostat Issues
Sometimes, the problem isn’t your AC at all—it’s your thermostat. Incorrect settings, dead batteries, or outdated units may cause your system to run without properly cooling your home.
5. Blocked or Leaky Ducts
In Naples homes, ductwork can develop leaks or become blocked, letting cool air escape before it reaches your living spaces. Professional duct inspection and sealing improves comfort and lowers energy bills.
Why You Shouldn’t Ignore the Problem
If your AC is running but not cooling, your system is wasting energy, driving up your utility bills, and potentially causing further damage. Prompt service can save you money and extend the life of your unit.
