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.
What to do if your air conditioner is running low on refrigerant?
Inspect the refrigerant line. On a central or split system, go outside and look for the largest pipe leading into your AC’s condenser. If your AC is on and this pipe has ice on it, shut your system off and give this pipe time to thaw before turning it back on. If this problem occurs again, you may be running low on refrigerant.
Why does my air conditioner stop working after a few minutes?
There are several possible causes of a vehicle’s air conditioning system to stop working after being on for only a few minutes. Basically the causes are either the A/C evaporator is getting too cold and icing up or there’s an electrical problem causing an open circuit. Long before I knew anything about A/C.
Why does my car air conditioner lose its cool?
A Leak in the A/C System A small refrigerant leak is the most common reason a car’s A/C gradually loses its cool. A leak is typically caused by a mixture of moisture and refrigerant that, when combined, creates a corrosive acid that eats away at seals, valves, and hoses in the A/C system.
When is it time to replace your air conditioner?

What to do if your AC is running but not Cooling Your House?

Is the fan speed control a variable speed?
Is your fan speed control a variable speed or does it have individual set speeds that can be selected for example, Off, 1, 2, 3, and so on? Just the blower is intermittent, not the compressor. Fan speed does not have set speeds, it’s more like a rheostat. It has the rotary control.
What can I do about intermittent blower motor?
Try cleaning it by cycling the control from minimum to maximum rapidly a dozen times or so with the truck off. If that does not work you could take the HVAC controller out and try to get some spray electrical contact cleaner inside the rheostat and again swiping it a number of times.
How does a different fan speed switch work?
Those of us that have a discrete number of fan speeds have a set of resistors whereby the fan speed switch selects a different resistor and thus a different fan speed.
What should the Fan Min on time be?
If the Fan Min On Time is set for 15 minutes or lower, the fan will operate in two separate segments across the hour; if the Fan Min On Time is set for 20 minutes or higher, the fan will run in four equal segments across the hour.
When do you deduct cooling time from Fan Min?
If a heating or cooling cycle operates within any given hour, the length of either cycle will be deducted from the Fan Min On Time. For example, if your cooling runs for 5 minutes and your Fan Min On Time is set to 20 minutes, 5 minutes will be deducted from the Fan Min On Time. 3. Quick Changes
What causes an electric fan to slow down and stop?
The run capacitor stores charge and delays the current momentarily, which gives the fan rotor time to turn and orient itself so that the induced magnetic force is effective. When the capacitor burns out, the electric current through the coil is too steady to generate torque, and the fan slows down and stops.
How does the Furnace Fan limit switch work?
Your furnace fan limit switch is basically a control system that determines when the furnace blower assembly should turn on and off. The system uses a “temperature probe” to detect temperature changes inside the heat exchanger (see image below) and turns your blower on and off in response.
Why does my AC run less in mild weather?

The others are compression, expansion, and radiation. The refrigerant is compressed by a belt driven compressor. It becomes a liquid. Heat is drawn off of it.
What should I do if my AC is cooling in 10 degree increments?
If your AC system previously cooled indoor air in 20 degree increments, it now may be cooling in 10 degree increments; the air conditioner works harder to condition the same amount of air. Have your preferred HVAC technician repair the leak, refill refrigerant and recalibrate.
