As summer rolls around, ACs become an integral part of our lives and we rely on them to keep us cool, comfortable, and safe. However, air conditioner problems can cause major disruptions in your daily life if they aren’t addressed quickly. Luckily, many AC issues can be solved by homeowners without calling in a technician. Here are seven common AC problems and how to fix them before they cause any serious damage:
AC won’t turn on.
Check the circuit breaker. If you’ve turned on an appliance or device and it won’t work, check to see if the power is off by flipping over your circuit breakers. Make sure they’re all in their correct positions and that there are no blown fuses.
Check the fuse. If flipping your breakers didn’t fix anything, it’s time to check out your fuses. These can be found in breaker boxes (usually located near where you plug in your appliances), so flip them out and replace them with new ones if necessary.
Check the thermostat. Your AC unit may not be working because of a faulty thermostat—they can wear down over time or become damaged by animals chewing at wires or even children playing with buttons! If this applies to you, consult an HVAC technician for help troubleshooting this problem before taking matters into their own hands with tools like pliers or screwdrivers (which could hurt themselves).
Check the power cord carefully for frays or tears that might cause electrical shorts when plugged into an outlet; also check whether any part of it has been exposed through stress fractures within insulation jackets around its length—this could mean internal damage has occurred somewhere inside due to friction between different surfaces rubbing against each other too hard during use over long periods of time!
First, check the circuit breaker or fuses for tripped breakers or blown fuses.
Second, check the thermostat to see if it is set on “heat” or “cool.” If so, turn it to “cool.” If you have an older model thermostat that uses mercury batteries (silver tube inside), then replace with new ones. Also make sure there are no damaged wires at the thermostat, as this could cause problems as well.
Thirdly, inspect the compressor and determine if it is running by looking at its fan blades which will be spinning when running—you can also listen for sounds coming from inside your unit that indicate whether or not everything is in working order there too!
Strange smells from AC vents.
Strange smells from your AC vents can be caused by a clog in the line or drain, or a leak. If you’ve been noticing odd odors lately, don’t panic—it’s probably just that time of year when it’s time to clean out your furnace and air conditioner!
To check for a clog in the line, open up all of your windows and doors and turn on one room’s AC unit at full blast. Close up all other rooms except for this one so there is no way for air to escape out of them while testing is under way. When you’re sure that all drafts have been shut down completely (or else there will be some serious backdrafts), leave the vent door open for about 10 minutes before re-entering with a flashlight and looking around. If there are any blockages or obstructions in front of fan blades or inside filters themselves, then cleaning will solve this problem once and for all!
If nothing shows itself during this process then move on to checking drains; if blocked drains were causing strange smells from AC vents then opening them up would release whatever was trapped behind there into room where occupants were being affected by it most directly (and hopefully not too heavily).
Strange noises from outside AC unit.
When you hear strange noises from outside your AC unit, it’s time to check for loose screws or other parts. If the sound is coming from the fan, check for a loose fan blade. It may be rattling against the frame or housing of your AC unit. Make sure that all screws are tight and that no wires have been damaged by vibrations. If you can’t find any problems with how things are assembled, there could be a problem with either:
