Why is my air conditioner blowing too hard?
Your AC cools air by blowing it over the evaporator coil. However, if the coil gets too cold, the condensation on it will freeze, turning the coil into a big block of ice. (See right image.) That ice limits the flow of air into your home. You will know if the evaporator coil is frozen if the refrigerant line outside is also covered in ice.
What happens when the air conditioner is too cold?
As far as too cold it may be possible to add speed controls to your blower but this would risk freezing the evaporator coil. HVAC systems are designed for peak load (unless a very new high end system) The compressor runs at full speed cooling until the set point is achieved then the compressor shuts down.
What does it mean when your AC is running but not Cooling Your House?
Your thermostat is switched to ON. If your thermostat switch is set to ON, that means the blower will run constantly—even when your system isn’t cooling your home, which will result in warm air blowing from your vents. How to fix it: Switch your thermostat to AUTO (see image below), so air only blows from your vents when the AC is cooling.
Why does my air conditioner make a blast sound?
The compressor in the condenser unit makes a blast sound whenever AC starts working, I removed the blades in condenser and ran the machine to make sure it is not fan motor or blades but I heard and saw the compressor making that big sound. Two different companies checked it.

Why does my AC have little air flow?
The usual reason for little air flow is the indoor ac coils get frozen not allowing enough cool air flow to circulate through them to get to the registers. Try #1 first. #1, 2, & 3 are important maintenance steps to keep the inside & outside units clean.
What happens if your air conditioner does not work?
Without it, your system would not be able to absorb heat from the rooms in your home and transfer it outside. If it starts to malfunction, your air conditioner has no chance of cooling your home properly. 6. Old system. When an air conditioner reaches the end of its operating life it will not be able to cool your home like it used to.
Why does my AC not run in the winter?
Same in winter with heat- little air flow. Since the air must pass thru the evap fins in both cases, the issue is consistent with the evap coils being clogged (fins). The tech that showed earlier never even mentioned this possibility!
