From maintenance problems to your unit getting old, there can be various reasons; nosotros have compiled an extensive listing to assistance yous effigy out why your Air-conditioning is not turning on and how to troubleshoot the cause.
1. Thermostat Malfunctioning
Your air conditioner has stopped working all suddenly. Yous panic and kickoff calling different air conditioner experts.
Only cease for a 2d. Have yous checked your thermostat?
Thermostat malfunctioning can have an impact on your air conditioner's performance.
First, bank check if the display of your thermostat is lit. If it'south off, it cannot signal the Air-conditioning to turn on. Second, check the batteries of your thermostat if you accept a battery-operated thermostat.
If the batteries are fine, then bank check the working of your thermostat. Set it to a cool setting, keeping it 5-6 degrees lower than the indoor temperature. After a few minutes, identify your hands in forepart of the AC vane to experience the cold air. If information technology has turned on, then voila, you take solved the event!
Only if your Ac all the same has not turned on, turn off your thermostat and take off the comprehend to bank check its components. Look for debris or corrosion build. Also, await for blown fuses; sometimes, they are the culprit. You can clean out the droppings yourself with a soft brush, but you would have to contact a professional for corrosion issues.
Further, check if in that location are whatsoever loose screws or wires inside the thermostat. You would have to refer to the user transmission for correct wiring schematics.
2. Low on Refrigerant
One of the reasons your AC is not turning on could be 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 AC or hot air in case of a estrus pump.
The refrigerant shortage is non due to your air conditioner using up the fluid. Leakage is a likely culprit in this situation. The cracks may build upwardly over fourth dimension in the Ac ringlet leading to leakage. Farther, non taking out time for regular maintenance can lead to corrosion in the long run.
You cannot do much on your own in this situation every bit it is non just about filling the refrigerant; the levels must friction match exactly with the levels specified by your AC's manufacture. You would have to contact a professional person to check the refrigerant levels and figure out the reason for leakage.
Y'all tin can avoid this trouble in the future by ensuring regular maintenance of your air conditioner.
3. Clogged Air Filters
Do you remember the concluding time you lot cleaned the air filters of your air conditioner?
If your answer is no, and so it's a big problem as your Ac may not be able to work properly due to muddy, clogged up filters. No affair what type of air conditioner you have, cleaning the filters is a must!
The job of the filters is to ensure proper air circulation. If they are filled with debris, then airflow is pretty much blocked. In this instance, your system has to work harder to cool your home, and over a period of fourth dimension, information technology tin can cease working.
Dirty air filters can also freeze your outdoor AC unit, which hinders your organization'due south working and, in some cases, is the reason why your AC is not turning on.
Weird, simply it happens.
The indoor unit of your AC has the evaporator scroll, and the outdoor unit contains the compressor. The refrigerant line is between these two components. When the airflow is restricted, warm air from your firm does not accomplish the refrigerant. The refrigerant then becomes so cold that any moisture on the coils freeze.
It's scary, merely yous don't need to panic. You can phone call a professional to deal with the situation, or yous tin clean the filters yourself. The ice on the coils will cook, so make sure to collect the water properly. Afterward cleaning, let the filters dry completely before turning on the air conditioner.
Nosotros recommend using a smart thermostat if you take a ducted arrangement or a smart Air-conditioning controller for a ductless mini-split unit to monitor your Air conditioning's air filter cleanliness level. Continuous monitoring can help avoid the issue of chock-full filters in the future.
iv. Your AC'southward Capacitor Has Died
If your HVAC unit has problem starting off if it is starting and stopping abruptly, or if you lot hear some clicking noises from the outdoor AC unit, chances are that your AC'southward capacitor has died down.
The capacitor is an integral part of your HVAC system. It is connected to the motor'southward circuit and gives the motor an initial push to kickoff running. The capacitor disconnects from the excursion once the motor reaches a specific speed.
There are 2 types of capacitors:
- The showtime capacitor provides voltage to get the motor started
- The run capacitor provides energy to keep them running
What Causes the Capacitor to Neglect?
Your AC's capacitor is sensitive to rut. Overheating tin can be acquired by your Air conditioning working difficult to achieve the desired temperature or due to its exposure to the sun. If your outside unit is installed on the roof, information technology will probable become a victim of overheating on hot summertime days.
During extreme cold or hot days, avert setting the highest/lowest temperature on your thermostat as it can also cause the unit to work harder, resulting in an overheated capacitor.
Power outages and power fluctuations tin can also significantly damage the capacitor. To prevent harm from power fluctuations, consider installing a surge protector.
Furthermore, old age can cause information technology to dice downward equally the capacitor'south ability to release free energy decreases over the years.
As far as the age is concerned, regular maintenance will help you observe capacitor bug early. The solution is quite elementary – accept an electrician supersede the capacitor.
Note: Never try to replace the capacitor yourself equally there is an electrical charge stored in it; there is a risk of severe electric shock. Never try to run your Air-conditioning on a bad capacitor every bit it can burn the motor attached to information technology, and replacing the motor tin be quite costly.
5. Dormancy Issue
If you cannot figure out why your AC is not working, check the fan. If the AC fan is not turning on, it could be a dormancy issue. Or if your cooling system was lying dormant in winters and yous have switched it on after some fourth dimension, then fans may notice information technology hard to offset rotating again considering of the dirt buildup.
Call an HVAC good; they volition know how to first the fans manually. The problem shouldn't persist in one case the fans are out of dormancy.
6. AC Not Turning On? – Check the Switch
It's the nearly obvious reason, but people overlook it all the fourth dimension.
But like any other electrical appliance, your AC also has an ON/OFF switch. Y'all will observe it near to where your system is installed.
Yous may not accept turned information technology off, but someone in your home could take done it. So, whenever your system refuses to turn on, practise check the switch before you practice anything else. The solution is simple, plough on the switch, and you would be feeling the pleasant breeze of air blowing in no time!
7. Uncleaned Condenser
Is your external AC unit not turning on?
The external or outside unit of measurement of your Ac is called a condenser. Its job is to release the rut collected by the within unit of measurement to the external environs.
Without regular maintenance, the condenser can become actually muddy over time. It will have to work harder to disperse the estrus equally dirt acts as an insulator. The condenser volition start drawing as well much current, tripping the circuit breaker, and your AC won't turn on.
If you think that the solution would be easy since you can clean the condenser yourself, well, unfortunately, it's too late for that now. Once it is non-functional due to dirt, it may be time for a professional make clean-up. Improper cleaning can impairment the compressor whorl'due south fins, which is way worse than the dirt on the coils.
You can, however, as a maintenance routine, keep cleaning your condenser regularly yourself to prevent whatever major issues.
8. Tripped Circuit Breaker
If you lot accept tripped the circuit breaker, your Air-conditioning won't turn on.
And so, whenever your AC unit is not turning on, practice check the circuit breaker.
A circuit breaker is a rubber tool that turns the power off in example of heavy voltage. It may be 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 information technology off completely. Then wait for a few minutes earlier turning it on.
Safe tip: If it keeps tripping, do non try to turn information technology on equally it indicates a high voltage and can cause an electric fire. It is a problem that needs to exist stock-still by an expert.
9. Is Your Ac Not Turning On Or Has It Run Its Course?
Your Air-conditioning has stopped running, and you are wondering what could be the reason. If information technology has been your condolement companion for quite a long time, perhaps information technology has reached the end of its lifespan.
But how can you really tell that it's time to say good day to your Ac?
Following are some signs indication why your AC is not turning on:
- You notice a pregnant decrease in AC's airflow. The decreased airflow can be due to muddy filters, simply if cleaning the filters does not work, your Ac has anile and needs replacing.
- Your AC requires repair services every now and then, which could give a clue if your Air-conditioning has problems related to its lifespan.
- Your bills are increasing at an abnormal rate. About the end of life, the Air-conditioning becomes sluggish and overworks to maintain the desired temperature, leading to a surge in bills. You can get for an energy audit to see if it is really your air conditioner causing the bills to increase.
- The inside unit of your Ac is leaking excessively. It may be due to a refrigerant leak, but fifty-fifty if the issue does not get resolved, it'due south time for the unit of measurement to get.
- If your Air conditioning is making weird loud noises such as grinding, screeching, rattling, it's time to supplant it as it signals a serious problem.
- Your air conditioner smells bad. It could be due to molds growing inside your unit or due to dingy filters, but if the olfactory property does non go away, consider replacing information technology.
If you are experiencing some of the in a higher place-mentioned signs and your AC is more than a decade onetime, you lot surely need a new unit. But practise non accept the decision on your ain, accept a professional thoroughly check your unit before going for a replacement.
Also, read these six ways to extend the average life of your Ac.
10. Chock-full Drain Pan
Your air conditioner unit non only cools or heats your firm but also removes moisture from the air. So, where does that moisture go?
It is collected in the drain pan, located underneath the indoor unit evaporator coils, then flows into the condensate drain line, which is directed outside.
Without regular cleaning, especially in areas with high humidity, the bleed pan can become clogged. The drain pan has a secondary bleed to forbid the pan from clogging. Just if both of them are full, this triggers the float switch, which turns the AC off. It is a safe mechanism that prevents excessive leakage in your house and prevents damages to the unit. But fifty-fifty then, the water leak from the clogged pan can harm your walls, ceilings, and furnishings.
And so, your Air conditioning is not going to plow on until the pan is cleaned and the float switch is turned down.
Yous tin utilize a wet/dry vacuum to suction the blockage out, but it is going to be actually messy then if yous don't want to meet all that gunk, better call an HVAC technician.
Make sure never to have this episode and practise regular maintenance. You lot tin can use a wet/dry out vacuum during the routine cleaning; we hope information technology won't be this messy!
eleven. Damaged Motor
If you hear grinding racket when you plough on the Air conditioning, information technology is non a good sign as it may indicate malfunctioning motor blades.
Motors are sealed to preclude any contact with the exterior air, water, or droppings. Over time, due to sometime 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 can wear out and can finish working entirely after some time. The outside unit cannot dissipate heat if the motor is faulty.
1 question that arises; should you repair the motor or supersede your air conditioner?
Here's a tip that will make it easy to decide; if it costs half the amount of the original price, then 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 Cord or Outlet
Sometimes the issue is not severe; information technology'southward just that you are anticipating the worst. So, examine simple things that are correct in front of you; check the power cord, for example.
The ability cord tin get frayed and vesture down if your unit was stored for a season. Power outages tin can as well harm the cord.
Unplug the cord for proper exam. If it shows signs of damage, you would accept to replace it.
Or peradventure it is not the string, simply the outlet was plugged in. You tin check if the outlet is working fine by plugging in other appliances. If none of them work, you lot know what's causing the issue.
Call an electrician for repairing or replacing the outlet, depending on the damage.
Safety tip: You should never attempt to repair the cord or power outlet yourself. There is a adventure of getting an electrical shock if y'all don't turn off the ability supply. Just turning the switch off won't do; you lot have to turn the power off from the master power box.
13. Your Air-conditioning Is Non the Right Size
Did you accept into account the size of an air conditioner when buying it? Well, it is a mistake that is continuously overlooked but tin can have a cracking impact on the performance of the HVAC system.
The air conditioner that is not the correct size will have to work harder and, at one point, will pause downward completely.
When your AC is larger than required, it will keep turning on and off rapidly, increasing wear and tear. Further, it won't remove the excess humidity as information technology does not stay on for a sufficient time.
On the other hand, a modest unit of measurement volition accept to run for a long fourth dimension to cool/warm the house, which may crusade overheating of the capacitor.
An HVAC system that is not the right size tin as well wreak havoc on your bills.
Unfortunately, the just solution is to supercede the unit of measurement.
Some parameters make up one's mind what size you crave, such as the area of your house, climate, number of windows, and insulation level. Y'all volition have to go for a professional person evaluation to discover out the perfect size of air conditioner for your dwelling.
There is besides an equation that roughly estimates the right size of Air conditioning.
(Foursquare footage of your home x 25/ 12000) – 0.5 = Required AC size
Let's say your expanse is one thousand foursquare feet.
(1000×25/12000) – 0.5= i.5
You require a 1.5-ton Air conditioning.
If you figured out why your AC was not turning on and managed to find the solution on your own, congratulations! Simply even then, we recommend that you contact a professional for a complete inspection to avoid like problems in the future.
By having an HVAC expert perform annual inspections and staying on meridian of the maintenance routine, you can avert any potential AC outages in the hereafter.
