From maintenance problems to your unit getting old, in that location can be various reasons; we have compiled an extensive list to help you figure out why your AC is non turning on and how to troubleshoot the cause.
1. Thermostat Malfunctioning
Your air conditioner has stopped working of a sudden. You panic and start calling different air conditioner experts.
Only cease for a second. Have you checked your thermostat?
Thermostat malfunctioning can have an bear upon on your air conditioner's performance.
Kickoff, bank check if the display of your thermostat is lit. If it's off, it cannot signal the AC to turn on. 2nd, check the batteries of your thermostat if you have a bombardment-operated thermostat.
If the batteries are fine, so bank check the working of your thermostat. Gear up it to a cool setting, keeping it 5-6 degrees lower than the indoor temperature. After a few minutes, place your hands in front of the AC vane to feel the common cold air. If it has turned on, then voila, you take solved the outcome!
But if your AC still has not turned on, turn off your thermostat and take off the cover to check its components. Look for debris or corrosion build. Too, look for blown fuses; sometimes, they are the culprit. You can make clean out the droppings yourself with a soft castor, just you would have to contact a professional for corrosion issues.
Further, check if there are any loose screws or wires inside the thermostat. You would have to refer to the user transmission for correct wiring schematics.
2. Depression on Refrigerant
One of the reasons your Air conditioning is not turning on could exist due to a refrigerant shortage.
A refrigerant is a cooling fluid residing in an Ac's coils. It is mainly responsible for providing the much-desired cool air from your Air-conditioning or hot air in example of a heat pump.
The refrigerant shortage is non due to your air conditioner using upwardly the fluid. Leakage is a likely culprit in this situation. The cracks may build up over time in the Ac whorl leading to leakage. Further, not taking out fourth dimension for regular maintenance tin atomic number 82 to corrosion in the long run.
You cannot do much on your own in this situation as information technology is not just about filling the refrigerant; the levels must match exactly with the levels specified past your Air conditioning's industry. You would take to contact a professional to bank check the refrigerant levels and figure out the reason for leakage.
You tin can avoid this problem in the future by ensuring regular maintenance of your air conditioner.
three. Chock-full Air Filters
Do you remember the last time you cleaned the air filters of your air conditioner?
If your answer is no, then it'southward a big problem as your AC may not be able to work properly due to dirty, clogged up filters. No matter what blazon of air conditioner you take, cleaning the filters is a must!
The job of the filters is to ensure proper air circulation. If they are filled with debris, and so airflow is pretty much blocked. In this case, your organisation has to work harder to cool your home, and over a flow of time, it can stop working.
Dirty air filters tin as well freeze your outdoor AC unit, which hinders your system's working and, in some cases, is the reason why your AC is not turning on.
Weird, but it happens.
The indoor unit of your Air conditioning has the evaporator gyre, and the outdoor unit contains the compressor. The refrigerant line is between these ii components. When the airflow is restricted, warm air from your house does non attain the refrigerant. The refrigerant and so becomes so cold that any moisture on the coils freeze.
It's scary, but yous don't need to panic. Y'all tin can call a professional to bargain with the state of affairs, or you tin can clean the filters yourself. The ice on the coils will melt, and then brand certain to collect the water properly. Later on cleaning, let the filters dry completely before turning on the air conditioner.
We recommend using a smart thermostat if y'all have a ducted organization or a smart AC controller for a ductless mini-split unit to monitor your AC'southward air filter cleanliness level. Continuous monitoring tin can assist avoid the issue of clogged filters in the future.
4. Your Air conditioning's Capacitor Has Died
If your HVAC unit of measurement has trouble starting off if it is starting and stopping abruptly, or if you hear some clicking noises from the outdoor AC unit, chances are that your Air-conditioning'due south capacitor has died down.
The capacitor is an integral role of your HVAC system. Information technology is connected to the motor'south circuit and gives the motor an initial push to start running. The capacitor disconnects from the excursion one time the motor reaches a specific speed.
There are 2 types of capacitors:
- The start capacitor provides voltage to go the motor started
- The run capacitor provides energy to keep them running
What Causes the Capacitor to Fail?
Your Air-conditioning's capacitor is sensitive to heat. Overheating can be caused past your AC working hard to reach the desired temperature or due to its exposure to the lord's day. If your outside unit is installed on the roof, it will likely become a victim of overheating on hot summer days.
During farthermost cold or hot days, avoid setting the highest/lowest temperature on your thermostat as it tin likewise crusade the unit to work harder, resulting in an overheated capacitor.
Power outages and power fluctuations tin also significantly harm the capacitor. To prevent damage from power fluctuations, consider installing a surge protector.
Furthermore, erstwhile age can cause information technology to die downwards every bit the capacitor'south ability to release energy decreases over the years.
As far as the age is concerned, regular maintenance will assist you detect capacitor problems early. The solution is quite simple – take an electrician replace the capacitor.
Notation: Never try to supercede the capacitor yourself every bit at that place is an electrical charge stored in it; at that place is a risk of astringent electric shock. Never endeavour to run your AC on a bad capacitor equally it can burn the motor attached to it, and replacing the motor can be quite plush.
5. Dormancy Event
If you cannot figure out why your AC is not working, check the fan. If the AC fan is non turning on, it could be a dormancy issue. Or if your cooling system was lying dormant in winters and you have switched it on after some fourth dimension, then fans may find information technology hard to start rotating again because of the dirt buildup.
Call an HVAC proficient; they will know how to start the fans manually. The problem shouldn't persist once the fans are out of dormancy.

Just like any other electric appliance, your AC also has an ON/OFF switch. Yous volition observe it near to where your system is installed.
Yous may not accept turned it off, simply someone in your home could take washed information technology. Then, whenever your arrangement refuses to turn on, exercise check the switch before yous do anything else. The solution is unproblematic, turn on the switch, and you would be feeling the pleasant cakewalk of air blowing in no time!
7. Uncleaned Condenser
Is your external AC unit non turning on?
The external or exterior unit of your Air conditioning is called a condenser. Its job is to release the heat collected by the inside unit to the external environment.
Without regular maintenance, the condenser tin go really muddy over time. It will have to work harder to disperse the oestrus equally clay acts every bit an insulator. The condenser will outset cartoon too much current, tripping the circuit breaker, and your AC won't turn on.
If you remember that the solution would be easy since you can clean the condenser yourself, well, unfortunately, it'due south too late for that now. Once it is not-functional due to dirt, it may be time for a professional clean-upwards. Improper cleaning can damage the compressor coil'south fins, which is way worse than the dirt on the coils.
You tin, even so, as a maintenance routine, keep cleaning your condenser regularly yourself to prevent whatsoever major issues.
8. Tripped Circuit Breaker
If you have tripped the excursion breaker, your Ac won't plough on.
So, whenever your AC unit of measurement is not turning on, do bank check the circuit breaker.
A circuit billow is a safety tool that turns the power off in case of heavy voltage. Information technology may exist due to using high voltage appliances or power surges in the electricity grid.
All you've to do is find the air conditioner circuit breaker and turn it off completely. Then wait for a few minutes before turning it on.
Safety tip: If it keeps tripping, exercise not try to turn information technology on as information technology indicates a high voltage and can crusade an electric fire. It is a trouble that needs to be fixed by an practiced.

ten. Clogged Drain Pan
Your air conditioner unit not only cools or heats your house just likewise removes moisture from the air. Then, where does that moisture get?
Information technology is collected in the drain pan, located underneath the indoor unit evaporator coils, so flows into the condensate drain line, which is directed outside.
Without regular cleaning, peculiarly in areas with loftier humidity, the drain pan can become clogged. The drain pan has a secondary drain to foreclose the pan from clogging. But if both of them are full, this triggers the float switch, which turns the AC off. It is a rubber machinery that prevents excessive leakage in your house and prevents damages to the unit of measurement. But even then, the water leak from the clogged pan tin can harm your walls, ceilings, and furnishings.
So, your AC is not going to plow on until the pan is cleaned and the float switch is turned down.
You tin can utilize a wet/dry vacuum to suction the blockage out, simply information technology is going to be really messy so if you don't want to see all that gunk, amend call an HVAC technician.
Make sure never to have this episode and exercise regular maintenance. You can use a moisture/dry vacuum during the routine cleaning; we hope it won't exist this messy!

Motors are sealed to foreclose whatsoever contact with the outside air, water, or debris. Over fourth dimension, due to erstwhile age or lack of maintenance, the seal can come off, and the oil which was sealed within the motor needed for lubrication seeps out. Without oil, the motor tin wear out and tin stop working entirely after some time. The exterior unit cannot misemploy estrus if the motor is faulty.
One question that arises; should yous repair the motor or replace your air conditioner?
Here'south a tip that will make it like shooting fish in a barrel to decide; if it costs half the amount of the original price, and so consider replacing your system. The price range is $150 to $750 for a new motor.
Contact an HVAC specialist for a thorough inspection.
12. Faulty Power String or Outlet
Sometimes the consequence is not severe; it'south merely that you are anticipating the worst. And so, examine elementary things that are right in front of you; check the power cord, for instance.
The ability cord tin can become frayed and vesture downward if your unit was stored for a flavor. Power outages can as well damage the cord.
Unplug the cord for proper examination. If information technology shows signs of damage, you would take to replace information technology.
Or perhaps it is not the string, merely the outlet was plugged in. You can bank check if the outlet is working fine past plugging in other appliances. If none of them work, you know what'south causing the upshot.
Call an electrician for repairing or replacing the outlet, depending on the harm.
Prophylactic tip: You should never attempt to repair the cord or power outlet yourself. There is a risk of getting an electric shock if you don't turn off the ability supply. Just turning the switch off won't do; you accept to turn the ability off from the chief power box.
13. Your AC Is Not the Right Size
Did you take into account the size of an air conditioner when buying it? Well, information technology is a mistake that is continuously overlooked but can have a bang-up bear on on the performance of the HVAC system.
The air conditioner that is not the right size will have to work harder and, at i point, volition intermission down completely.
When your Ac is larger than required, it volition keep turning on and off quickly, increasing wear and tear. Further, it won't remove the excess humidity equally it does not stay on for a sufficient fourth dimension.
On the other hand, a pocket-size unit will take to run for a long fourth dimension to cool/warm the house, which may cause overheating of the capacitor.
An HVAC system that is not the right size tin likewise wreak havoc on your bills.
