If your AC is making squealing, grinding, or chattering noises that it never used to make before, it needs to be checked immediately. These sounds indicate an issue and can cause significant damage to your unit.
If you see any water pools around your air conditioner, this may be a warning that the drain tube is blocked or broken. This can lead to mold growth and expensive repairs.
Your AC Won’t Turn On
It could be a simple issue if your AC won’t turn on. Verify that all the present parts are plugged in and switched on. Some older systems have a shut-off switch that can be flipped manually. If this is reversed, neither the inside nor outside units can turn on. It’s a good idea to get a multimeter and learn how to use it, as Numerous factors can result in this issue – from pests chewing through wires to a blown fuse.
A clogged drain line can also cause an air conditioner to stop working. The internal unit has a pan that catches any condensation it can’t remove – this pan is connected to the external system with a line that drains water into a drain pan in your yard or attic (the ‘drain line’). If this gets clogged with sludge, it will trigger a ‘float switch’ that shuts down your system, preventing it from flooding your house with residual moisture.
Other causes of an air conditioner not turning on include a thermostat issue, low refrigerant, and a frozen coil. If you see any indications of these problems, turn off your AC and immediately call a professional.
Your AC Won’t Cool
If you see warm air emanating from your vents, it can indicate that the compressor that needs to be repaired isn’t working correctly. The AC system’s brain is the compressor, and a refrigerant is circulated between the inside and exterior units. If it’s damaged, the entire system won’t cool your home.
Another possible cause of this is that you have leaky ductwork, which reduces the amount of cooled air that reaches your living spaces. Call an HVAC repair specialist, like those at AC Works 365, immediately if you’re concerned about your ductwork, as it needs to be treated as soon as possible.
If you’re hearing strange sounds like banging, rattling, or squealing, it’s time to shut off your AC unit and have an expert check it out. These sounds usually reflect a bigger problem, such as fractured motor bearings or the belt slipping. These are often a result of improper maintenance and can lead to more expensive repairs or replacements if addressed after some time.
Your AC Won’t Stay Cool
It may be a thermostat issue if your AC turns on and off frequently or doesn’t reach the desired temperature. If this is the case, you’ll want to contact a professional Dallas AC repair immediately to determine if it needs a replacement.
A rising electric bill can also indicate something wrong with your air conditioning. If you’re seeing a massive jump in your energy bills, it could be caused by dirty or blocked registers forcing your AC to work much harder to keep your home cool.
Another sign that your AC might need repair is strange sounds from your unit. Grinding, squealing, or scraping isn’t normal and shouldn’t be ignored. These noises could reflect a loose belt, a broken component, or a refrigerant leak. If left unattended, these issues can escalate into costly repairs or replacements.
Your AC Won’t Turn Off
If your air conditioner is constantly running and you are unable to shut it off, your thermostat may be to blame. The thermostat is the command center of your AC system, and it communicates with the unit to let it know what temperature to maintain in the house. When the thermostat malfunctions and relays the wrong information, the system will run nonstop until it’s shut off.
If the AC is constantly running, it may also be a sign that it’s too old or too small for your home. Regardless of the problem, you should contact an HVAC professional immediately.
Unexpected sounds such as banging, rattling, and squealing can also indicate a severe AC issue that needs to be repaired. If you hear these sounds, turn off your AC and call an expert as soon as possible to avoid further damage to the equipment.
A tripped breaker is another sign that your AC needs repair. To check if the breaker is tripped, open the electrical panel inside your home and look for the switch in the “OFF” position. Flipping the switch back to the “ON” position will restore power to your air conditioner.
Your AC Won’t Turn On
If your AC won’t turn on or has stopped working, you should check to see if any circuit breakers have been flipped off. This is a common cause for AC units not turning on, which can be easily fixed at home.
Next, ensure the internal unit’s drain pan isn’t complete or clogged. The drain line allows condensation to run out of the internal team, and if it gets clogged, it can trigger a switch that shuts off the system. Unclogging using a wet/dry vac or pipe snake can fix this.
You should also ensure the voltage passes in and out of your transformer if you suspect it’s a problem. If you find power going into the transformer but nothing coming out, it could mean your transformer has blown or there’s another electrical issue. A multimeter can help here; if you know how to use one, it’s an easy fix for most homeowners. If the problem persists, it’s best to call a professional.
It’s nice that you mentioned how warm air emanating from the vents could indicate that the compressor that needs to be repaired isn’t working correctly. I tried to use our AC earlier but it didn’t cool our room for some reason. Something is definitely wrong with the AC, so we should probably call an air conditioning repair company immediately.
