When it’s hot, who doesn’t want to turn on the air conditioning? We have all sorts of problems with our AC units, and it’s not always easy to figure out why they won’t turn on. Here are five reasons why your air conditioner won’t work!
These are some common reasons for an AC not working. An AC filter could be dirty, there could be too much humidity in the air, your drain line might have clogged, or you need to replace components of your system. Finally, your system may just be overloaded!
Your AC is a complex system of parts that need to work in unison to keep your home cool. Its surprising that issues such as these can lead to a complete breakdown. Lets explore further how these can stop your home from staying cool.
Dirty or Old Air Filter
In order for your air conditioner to work properly, you need to change the air filter every month. If you have a dirty filter, it can cause the system to overheat and not blow cold air.
Humidity in the Air
When there’s too much humidity in the air, it can cause your AC unit to freeze up and not turn on. If you live in a humid area, you should add a dehumidifier during hot months so that water will be extracted from the air.
Blocked Drain Line
Sometimes your drain line could get clogged by debris like leaves or dirt, which can prevent water from flowing out of your AC unit and cause it not to work properly. You may need to call a professional plumber to clean out your drain line or replace parts of it if they are damaged.
If all else fails and none of these reasons are causing your unit not to turn on, you may need to replace some of your unit’s components. If your AC is more than ten years old or has been in a storm, you should consider replacing the compressor and other parts. If you plan on doing this yourself, it’s best to contact a repairman for advice.
AC is Overloaded
If your air conditioner has been turned on for too long without cooling down the house, the thermostat may be set too high and will not allow the unit to turn off. This causes the system to overheat and may cause damage which could make it not work at all.
What to Do When Your Air Conditioner Doesn’t Work
If your air conditioner doesn’t work, you should call an air conditioning repair service immediately. Not only will they be able to fix your unit, but they can also help you determine what is causing it not to work. Don’t wait until the weather gets really hot and humid before you call them!
If the weather is very hot, open up windows and use fans to move the air around. This will help cool down the house until you can get your AC unit repaired.
How To Fix a Noisy AC Unit
If your air conditioner makes too much noise, it could be a sign that something is wrong with it. If you want to fix this problem yourself, here are some things you can do:
- Check the drain hose. Make sure it’s not clogged and is properly attached to the outside of the unit.
- Clean out debris from the blower compartment. This will reduce friction and noise.
- Check outside for loose screws or parts that may be rubbing against each other and making noise.
- Make sure all of your vents are open, and there are no obstructions in them like furniture or clothing.
How to complete AC Maintenance
If you know how to do basic AC maintenance, it will save you a lot of money and keep your unit running smoothly. Here are some things to do:
- Check out the air filters. They should be changed at least once a year. If yours is dirty, clean it or replace it.
- Check the outdoor condenser coil for dirt and debris. Clean it with a stiff brush or vacuum attachment before replacing the blower wheel assembly.
- Check your evaporator coils for loose parts or frost build-up on the coils themselves. Clean them with a brush or vacuum cleaner attachment before replacing them with new ones.
- Replace any worn-out parts like fan motors, blower motors, fan blades, and other parts that wear out over time to keep your unit running smoothly.
If you follow these tips, your air conditioner will last for many years. If you notice a problem with your AC unit, such as a loud noise or a broken part, don’t wait to call an HVAC professional. These problems can get worse over time and cause even more damage to your AC unit and your property.
