If your AC is not cooling but the fan is running in Sarasota, FL, several problems can be the culprit. You may have an outdoor compressor complication, blocked airflow, or a problem with the thermostat setting. For example, a dirty outdoor compressor or a faulty component can prevent the system from operating properly.
When you find yourself dealing with this cooling issue, Arctic Air Home Services can help with our expert AC repair service. Our technicians will get to the root of the problem and provide you with long-lasting solutions.
First Check: Thermostat, Breaker & Air Filter
To ensure your thermostat is communicating with your AC, set it on “cool” and not “heat” or “off.” Next, set the temperature to a few degrees below the current room temperature to see if the system starts cooling. Finally, try setting the fan to “auto.” When it’s set to “on,” the blower fan runs, even when the system isn’t cooling.
If your AC runs but is not cooling, the system may not be getting power. Check to see if you have a tripped circuit breaker.
When your AC is blowing air, but it’s not cold, check the air filter. If it’s dirty, you need to replace or clean it, depending on your system.
If the thermostat, breaker, and air filter are all in good condition, there must be another issue. Our technicians can inspect your AC, locate the problem, and make the necessary repairs to restore your comfort.
Warm Air From the Vents: Refrigerant & Compressor Clues
Refrigerant absorbs your indoor heat and carries it outside to release it. Refrigerant doesn’t wear out. If your refrigerant levels are low, it’s due to a leak.
There are specific clues that indicate an issue with the refrigerant resulting in the AC running but no cold air. There can be an oily residue around the hose fittings or pipe connections. You may also hear hissing sounds as the refrigerant escapes.
When your AC’s refrigerant level drops, the pressure inside the evaporator drops. This causes the moisture on the coils to freeze. That ice restricts airflow, which also leads to the AC fan running but no cold air.
The compressor is responsible for pressurizing the refrigerant gas so it can move heat outdoors. If the compressor’s clutch doesn’t engage, it won’t spin, which means the refrigerant won’t circulate. If the compressor fails to start or runs hot, the problem may be a failing capacitor or contactor.
Clues signalling a compressor issue when your AC runs but is not cooling include strange noises. Instead of a quiet hum, it will chatter, screech, or clank. This indicates internal mechanical failure, failing bearings, or dangerously high system pressures, which require professional repairs.
Frozen Coil or Dirty Condenser? How to Tell the Difference
To tell the difference between a frozen coil and a dirty condenser, there are a few things you need to check. This includes the air filter and outdoor components. Restricted airflow or low refrigerant leads to a frozen coil. Watch for warning signs, like warm airflow, visible ice, unusual noises, and pooling water.
On the other hand, a dirty condenser struggles to release heat. This makes your outdoor compressor work inefficiently. Watch for poor airflow, noisy operation, and longer cooling cycles.
Why the Fan Runs but the Compressor Doesn’t
If your AC runs but the compressor doesn’t, you may have faulty start/run capacitors, overheated compressors, or tripped safety switches. These issues require professional assistance.
Safe DIY Checks Before You Call
Before you call for AC repairs, there are preventative checks you can safely do yourself. In addition to checking the thermostat, breaker, and air filter, clear debris from the outdoor condenser. Unblock your indoor vents too. If there’s still an issue, don’t hesitate to contact us.
