But sometimes, your HVAC unit can leave your side and refuse to turn on. If you're facing a similar situation, then don't fret! It might exist something that can exist easily fixed as a DIY solution or, in some cases, with a telephone call to a professional.
From maintenance issues to your unit getting erstwhile, there tin can exist various reasons; we have compiled an extensive list to assistance you figure out why your Air conditioning is not turning on and how to troubleshoot the cause.
ane. Thermostat Malfunctioning
Your air conditioner has stopped working all of a sudden. You panic and starting time calling different air conditioner experts.
But stop for a second. Have y'all checked your thermostat?
Thermostat malfunctioning can have an impact on your air conditioner's operation.
First, bank check if the display of your thermostat is lit. If it's off, it cannot betoken the AC to plough on. Second, check the batteries of your thermostat if you take a bombardment-operated thermostat.
If the batteries are fine, then check the working of your thermostat. Set information technology to a absurd setting, keeping it 5-6 degrees lower than the indoor temperature. Afterward a few minutes, place your hands in front of the Air-conditioning vane to feel the cold air. If information technology has turned on, then voila, you lot take solved the result!
But if your AC still has not turned on, plough off your thermostat and accept off the cover to cheque its components. Look for droppings or corrosion build. Also, look for blown fuses; sometimes, they are the culprit. You can clean out the debris yourself with a soft brush, only you lot would have to contact a professional person for corrosion issues.
Further, check if there are any loose screws or wires inside the thermostat. Yous would have to refer to the user manual 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 Air-conditioning'due south coils. Information technology is mainly responsible for providing the much-desired cool air from your Ac or hot air in case of a heat pump.
The refrigerant shortage is not 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 coil leading to leakage. Further, not taking out time for regular maintenance tin lead to corrosion in the long run.
Y'all cannot exercise much on your own in this situation as it is not only about filling the refrigerant; the levels must friction match exactly with the levels specified past your Air conditioning'due south manufacture. Yous would have to contact a professional to check the refrigerant levels and effigy out the reason for leakage.
You can avoid this problem in the future past ensuring regular maintenance of your air conditioner.
three. Chock-full Air Filters
Exercise you remember the last time you cleaned the air filters of your air conditioner?
If your answer is no, so information technology's a big problem as your Air conditioning may not exist able to work properly due to dirty, clogged up filters. No thing what type of air conditioner you lot accept, cleaning the filters is a must!
The task of the filters is to ensure proper air circulation. If they are filled with debris, and then airflow is pretty much blocked. In this case, your organization has to piece of work harder to cool your dwelling, and over a period of time, information technology tin stop working.
Dirty air filters can as well freeze your outdoor Air-conditioning unit, which hinders your organisation'due south working and, in some cases, is the reason why your Air conditioning is not turning on.
Weird, but it happens.
The indoor unit of your AC has the evaporator coil, and the outdoor unit of measurement contains the compressor. The refrigerant line is betwixt these two components. When the airflow is restricted, warm air from your firm does non accomplish the refrigerant. The refrigerant so becomes so cold that whatever moisture on the coils freeze.
It's scary, simply you don't demand to panic. You can call a professional person to bargain with the situation, or you can clean the filters yourself. The ice on the coils will melt, so make certain to collect the water properly. After cleaning, let the filters dry completely before turning on the air conditioner.
We recommend using a smart thermostat if yous have a ducted organization or a smart AC controller for a ductless mini-split unit to monitor your AC's air filter cleanliness level. Continuous monitoring tin can aid avoid the issue of clogged filters in the future.
4. Your Air-conditioning'due south Capacitor Has Died
If your HVAC unit has trouble starting off if it is starting and stopping abruptly, or if y'all hear some clicking noises from the outdoor AC unit of measurement, chances are that your AC'due south capacitor has died down.
The capacitor is an integral function of your HVAC arrangement. It is connected to the motor'south circuit and gives the motor an initial push button to start running. The capacitor disconnects from the circuit one time the motor reaches a specific speed.
In that location are two types of capacitors:
- The start capacitor provides voltage to go the motor started
- The run capacitor provides energy to continue them running
What Causes the Capacitor to Fail?
Your AC's capacitor is sensitive to heat. Overheating can be acquired past your AC working hard to accomplish the desired temperature or due to its exposure to the sun. If your outside unit is installed on the roof, it will probable become a victim of overheating on hot summer days.
During extreme cold or hot days, avert setting the highest/lowest temperature on your thermostat as it can also crusade the unit to work harder, resulting in an overheated capacitor.
Ability outages and ability fluctuations can also significantly damage the capacitor. To foreclose harm from power fluctuations, consider installing a surge protector.
Furthermore, old historic period can cause information technology to dice downwards as the capacitor's ability to release energy decreases over the years.
As far as the historic period is concerned, regular maintenance will help yous discover capacitor issues early. The solution is quite simple – have an electrician replace the capacitor.
Note: Never try to replace the capacitor yourself equally at that place is an electrical charge stored in it; in that location is a adventure of astringent electric daze. Never try to run your AC on a bad capacitor every bit it can burn the motor attached to it, and replacing the motor can be quite costly.
5. Dormancy Effect
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 fallow in winters and you have switched information technology on after some fourth dimension, then fans may observe it difficult to start rotating again because of the dirt buildup.
Call an HVAC expert; they will know how to get-go the fans manually. The problem shouldn't persist in one case the fans are out of dormancy.
6. Air conditioning Not Turning On? – Cheque the Switch
It's the most obvious reason, but people overlook information technology all the time.
Simply like whatever other electric appliance, your AC likewise has an ON/OFF switch. You volition find it near to where your organisation is installed.
You may non have turned information technology off, but someone in your home could take washed it. So, whenever your system refuses to turn on, do check the switch earlier you do anything else. The solution is simple, turn on the switch, and y'all would be feeling the pleasant cakewalk of air bravado in no time!
7. Uncleaned Condenser
Is your external AC unit of measurement not turning on?
The external or outside unit of your Air-conditioning is called a condenser. Its job is to release the heat collected by the inside unit of measurement to the external environment.
Without regular maintenance, the condenser tin can get really dirty over time. Information technology will take to piece of work harder to disperse the rut equally dirt acts as an insulator. The condenser volition get-go cartoon too much electric current, tripping the excursion breaker, and your Ac won't turn on.
If you think that the solution would be easy since you tin can clean the condenser yourself, well, unfortunately, it's likewise late for that now. Once it is non-functional due to dirt, it may be time for a professional clean-up. Improper cleaning tin can impairment the compressor coil'southward fins, which is mode worse than the dirt on the coils.
You tin, withal, as a maintenance routine, keep cleaning your condenser regularly yourself to forestall any major issues.
8. Tripped Circuit Breaker
If y'all have tripped the circuit breaker, your AC won't turn on.
Then, whenever your AC unit is not turning on, do check the excursion breaker.
A circuit billow is a safety tool that turns the power off in example of heavy voltage. It may exist due to using loftier voltage appliances or power surges in the electricity grid.
All you've to practise is find the air conditioner excursion breaker and turn it off completely. Then wait for a few minutes earlier turning it on.
Safe tip: If information technology keeps tripping, do non try to turn it on equally it indicates a high voltage and can cause an electrical burn. It is a problem that needs to exist fixed by an expert.
9. Is Your Ac Not Turning On Or Has It Run Its Course?
Your AC has stopped running, and y'all are wondering what could be the reason. If it has been your condolement companion for quite a long time, mayhap it has reached the stop of its lifespan.
But how can you actually tell that it's time to say goodbye to your Air conditioning?
Following are some signs indication why your Air conditioning is not turning on:
- You notice a significant subtract in Air-conditioning'due south airflow. The decreased airflow tin can be due to dirty filters, but if cleaning the filters does non work, your Ac has anile and needs replacing.
- Your Air-conditioning requires repair services every now and and then, which could give a clue if your AC has problems related to its lifespan.
- Your bills are increasing at an aberrant rate. Near the cease of life, the AC becomes sluggish and overworks to maintain the desired temperature, leading to a surge in bills. You lot can become for an free energy audit to run into if it is really your air conditioner causing the bills to increase.
- The within unit of your AC is leaking excessively. It may be due to a refrigerant leak, only even if the issue does not get resolved, it's time for the unit to get.
- If your Air-conditioning is making weird loud noises such as grinding, screeching, rattling, it'due south fourth dimension to replace it as it signals a serious trouble.
- Your air conditioner smells bad. It could be due to molds growing inside your unit or due to dirty filters, but if the smell does not become away, consider replacing information technology.
If yous are experiencing some of the above-mentioned signs and your AC is more than a decade old, you surely need a new unit. But do not take the conclusion on your own, have a professional thoroughly cheque your unit before going for a replacement.
Also, read these six ways to extend the average life of your AC.
ten. Clogged Drain Pan
Your air conditioner unit not simply cools or heats your firm but likewise removes moisture from the air. And so, where does that moisture go?
It is collected in the bleed 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 drain pan can become clogged. The drain pan has a secondary drain to prevent the pan from clogging. But if both of them are total, this triggers the float switch, which turns the Ac off. Information technology is a safety machinery that prevents excessive leakage in your house and prevents damages to the unit. But even then, the water leak from the clogged pan can harm your walls, ceilings, and furnishings.
So, your Air-conditioning is not going to turn on until the pan is cleaned and the float switch is turned downwardly.
Y'all can use a wet/dry vacuum to suction the blockage out, just it is going to be actually messy so if y'all don't want to come across all that gunk, better call an HVAC technician.
Make certain never to take this episode and do regular maintenance. You lot tin use a moisture/dry vacuum during the routine cleaning; we hope it won't be this messy!
11. Damaged Motor
If you hear grinding racket when you plow on the AC, it is not a good sign as it may bespeak malfunctioning motor blades.
Motors are sealed to prevent any contact with the outside air, h2o, or droppings. Over time, due to old age or lack of maintenance, the seal tin can come up off, and the oil which was sealed inside the motor needed for lubrication seeps out. Without oil, the motor can wear out and can end working entirely after some time. The outside unit cannot dissipate heat if the motor is faulty.
One question that arises; should you repair the motor or replace your air conditioner?
Here's a tip that will arrive easy to decide; if it costs one-half the amount of the original price, then consider replacing your arrangement. The price range is $150 to $750 for a new motor.
Contact an HVAC specialist for a thorough inspection.
12. Faulty Ability Cord or Outlet
Sometimes the issue is not severe; it'due south but that you are anticipating the worst. So, examine simple things that are correct in front end of you; check the ability cord, for instance.
The power cord tin can get 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 accept to replace information technology.
Or peradventure it is not the cord, but the outlet was plugged in. You tin check if the outlet is working fine by plugging in other appliances. If none of them work, yous know what's causing the issue.
Call an electrician for repairing or replacing the outlet, depending on the impairment.
Safety tip: You should never attempt to repair the cord or power outlet yourself. There is a risk of getting an electric shock if yous don't turn off the power supply. But turning the switch off won't exercise; you lot have to turn the ability off from the chief ability box.
13. Your AC Is Non the Right Size
Did you have into account the size of an air conditioner when ownership it? Well, information technology is a mistake that is continuously disregarded but can have a great touch on on the performance of the HVAC arrangement.
The air conditioner that is not the right size volition have to work harder and, at one signal, volition suspension downward completely.
When your AC is larger than required, it volition keep turning on and off quickly, increasing article of clothing and tear. Farther, information technology won't remove the excess humidity as it does not stay on for a sufficient time.
On the other paw, a modest unit volition have to run for a long time to cool/warm the house, which may crusade overheating of the capacitor.
An HVAC arrangement that is not the right size tin likewise wreak havoc on your bills.
Unfortunately, the only solution is to supersede the unit.
Some parameters determine what size y'all require, such as the surface area of your business firm, 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.
In that location is also an equation that roughly estimates the right size of AC.
(Square footage of your habitation x 25/ 12000) – 0.v = Required Ac size
Let's say your area is thousand square feet.
(1000×25/12000) – 0.5= 1.5
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 lot contact a professional for a complete inspection to avert like problems in the future.
By having an HVAC proficient perform annual inspections and staying on top of the maintenance routine, you tin can avoid whatever potential AC outages in the time to come.
