Faulty Power Cord Or Outlet
Sometimes the issue is not severe its just that you are anticipating the worst. So, examine simple things that are right in front of you check the power cord, for instance.
The power cord can become frayed and wear down if your unit was stored for a season. Power outages can also damage the cord.
Unplug the cord for proper examination. If it shows signs of damage, you would have to replace it.
Or maybe it is not the cord, but the outlet was plugged in. You can check if the outlet is working fine by plugging in other appliances. If none of them work, you know whats causing the issue.
Safety tip: You should never attempt to repair the cord or power outlet yourself. There is a risk of getting an electric shock if you dont turn off the power supply. Just turning the switch off wont do you have to turn the power off from the main power box.
Ac Fan Won’t Turn Off
If your AC unit fan won’t turn off or is stuck while running, that’s a different problem most often caused by a stuck relay that is keeping the circuit closed. To troubleshoot this issue, Reddi Heating & Cooling recommends checking the thermostat settings. Set your desired temperature above the current one and wait for the unit to shut off. If the fan is still blowing, make sure that the fan isn’t set to “on” and that it is still running once you change it to “auto” or “off.”
If the fan still doesn’t turn off, the relays inside the unit that help to close and open its electrical circuits could have failed or become stuck together. The thermostat might also be broken and may need replacement. Otherwise, the filters could be clogged, the condensers might be dirty or the evaporator coils could be frozen. Sometimes, these are maintenance issues, so getting an AC unit tuneup could solve the problem.

Your Ac Is Not The Right Size
Did you take into account the size of an air conditioner when buying it? Well, it is a mistake that is continuously overlooked but can have a great impact on the performance of the HVAC system.
The air conditioner that is not the right size will have to work harder and, at one point, will break down completely.
When your AC is larger than required, it will keep turning on and off quickly, increasing wear and tear. Further, it wont remove the excess humidity as it does not stay on for a sufficient time.
On the other hand, a small unit will have to run for a long time to cool/warm the house, which may cause overheating of the capacitor.
An HVAC system that is not the right size can also wreak havoc on your bills.
Unfortunately, the only solution is to replace the unit.
Some parameters determine what size you require, such as the area of your house, climate, number of windows, and insulation level. You will have to go for a professional evaluation to find out the perfect size of air conditioner for your home.
There is also an equation that roughly estimates the right size of AC.
0.5 = Required AC size
Lets say your area is 1000 square feet.
You require a 1.5-ton AC.
If you figured out why your AC was not turning on and managed to find the solution on your own, congratulations! But even then, we recommend that you contact a professional for a complete inspection to avoid similar problems in the future.
Potential Cause : Clogged Drain Line
The condensate drain line could be clogged causing the issue. In order to operate, air conditioning units create condensation, which in turn goes through a drain line. Naturally, if this line is clogged, your air conditioner wont turn on as a safety switch will trip to avoid serious damager or danger.

Trouble Adjusting The Thermostat
Speaking of the thermostat, glitches within the control center of your air conditioner could also pose a problem. Failure to turn on an AC unit thats blowing warm air are both signs of a thermostat issue.
First, make sure your thermostat is calibrated correctly. Some people think that new, high-tech thermostats and SMART technology have replaced the need for calibration, but this simply isnt true.
Even digital thermostats need to be properly calibrated to work efficiently. Calibration is what tells your homes AC unit to turn on when the house hits a certain temperature.
If your thermostat is calibrated correctly but the AC still isnt working, check that its set to the lowest possible temperature. This should kick start the unit. If not, it may be time to call in the experts.
HVAC repair technicians know how to recalibrate both older and newer thermostats. The digital varieties are sometimes more confusing than the older models. Have your owners manual handy to help the technician troubleshoot the problem.
Wait And Turn The Circuit Breaker On
Next, turn off the circuit, wait for 20-30 minutes, and set to cool. At this point, it should start to cool your home back like it used to. After waiting and cooling down your air conditioner, turn it back again. It should now start working properly, but if for some reason, it is not running, get an HVAC expert who will check it make sure it is working properly. You should also call them for AC service if your unit shut down repeatedly.
As soon as you notice that your air conditioner isnt turning on or the power button is not working, you should call a heating and cooling professional. A little delay in air conditioner repair can cost you big bucks. Besides, delay in AC servicing can lead to system shutdown.
Again, if you need to reset your air conditioner, you can follow the tips and steps I described above.

Always remember, safety is above all, and try to take help when its needed. So, for your HVAC Duct Cleaning, air conditioning repair and compressor repair needs, .

A/c Wont Maintain The Set Temperature
If your air conditioner doesnt cool evenly throughout the day, or if you notice that rooms near the thermostat dont get as cool as the thermostat setting, you may need to evaluate the placement of the thermostat and consider moving it to a better location.
The thermostat should never be mounted on the inside of an exterior wall, since the temperature along the inside of the wall will be influenced by outdoor conditions such as bright sunlight that might keep it from reading the actual temperature inside the room accurately.
Thermostats should be placed in the middle of interior walls where theyre exposed to air moving inside the rooms theyre in. They should not be placed behind open doors or behind drapes, since the air in those places will tend to be stagnant and not change temperatures quickly as the air conditioner runs.
Ensure That Ac Is Getting Power
Whenever an air conditioner doesnt start, check if it has power. The first thing you should do is always check the ACs cord to make sure it is plugged in. If the unit has power but still isnt cooling, there could be one of several issues: the thermostat could be set incorrectly, there may be a problem with the fan, or the compressor may need servicing.
If your air conditioner suddenly stops working and you dont know what the problem is, there are a few easy checks you can make before calling a professional. First, check that the cord connected to your unit isnt unplugged. If it is, re-plug it and see if this fixes your problem. If not, pull back any nearby furniture or rugs to see if theres a chance the plug got tangled with something while it was plugged in.
Check the Air Conditioner on/off switch. Flip it to the on position to see if it starts working. If the window unit turns on and begins to run normally, great! If it does not, lets take a look at the cord.

What Does An Ac Compressor Do
A compressor is a vital part of an air conditioning systemthe rest of the system cant function without it! To put it simply, the AC compressor works to move refrigerant through the appliance. As the compressor moves refrigerant, it compresses the cold gas until it becomes hot and pressurized. The heat is then transferred outside, which cools your home in the process.
Why Your Ac Thermostat Has A Fan Switch
Think of the fan switch like a whole-house ceiling fan. When you turn it to on, it constantly pulls air through the HVAC return and blows it back out the supply vents. The most common use for this setting is for air filtration. The more you move air across your air filter and/or air purifier, the cleaner your indoor air.

The Condenser Unit Turns On And Off Repeatedly
The outdoor condenser unit contains safety controls that automatically shut down the system when the pressure drops below a certain level. Once pressure rises again, the system starts up. Pressure can change with general temperature as well as refrigerant levels contained inside the central air.
If your condenser continues to turn on and off, your AC contractor can assess the safety controls ensure correct performance.
Another reason your AC system could be repeatedly turning on and off is if its short cycling. It happens when your AC cant reach the temperature on the thermostat or reaches that temperature too soon. The machine will constantly turn on and off while never completing a full cycle.
