An air conditioner is one of those appliances you notice more when it isn’t working than when it is. Sure, there are those first five seconds when you walk into a cool room, but that feeling quickly fades into the background like the hum of the condenser.
Refrigerant or Water Leakage
Leaking liquids and electricity are rarely a great combo. When you have a dribbling air conditioner, it doesn’t hurt to reach out to a professional and describe the issue. That leak may be a little deal or a big one, but it usually doesn’t hurt to check. For example, some older systems use a liquid refrigerant to supply cooling power, and if that liquid has leaked out then the system, the unit is going to have a hard time functioning properly.
Replacing the Filter
Filters help ensure that the air that comes out of your vents is clean and free from dust, dirt, and other types of allergens and contaminants. They also help increase the efficiency of your unit (circulating dust-filled air requires a lot more work).
AC Not Turing On
There are numerous reasons an air conditioner may not power up. You can even find top 10 lists filled with the possibilities. Unless you have a lot of experience with air conditioners, diagnosing the issue probably isn't something you want to do yourself because it can become a lesson in frustration or lead to further issues. Of course, check the fuse first. If that's not the problem, then it could be an issue with the thermostat. Try lowering the temperature to check if the unit responds. If the problem persists, then, call an air conditioning technician. Usually a specialist can figure out what’s wrong with your machine fairly quickly.
Repeatedly Tripping a Fuse
Busting a fuse can be caused by a few different things. While a tripped fuse is relatively easy to fix, if the issue occurs whenver you turn your AC on, it may be time to call in an expert. Perhaps this is happening because of faulty wiring or because there's a problem with the thermostat. Regardless, this isn't something you want to try and fix yourself if it keeps continuing because you might risk causing further damage. It's best to get the professional opinion of a technician so that they can troubleshoot your unit.
Dusting the Machinery
A lot of people let their air conditioners putter on year after year without cleaning them inside and out. While this isn’t necessarily a problem you can diagnose, regular cleaning will often stop problems from happening in the first place. Take the above video as a cautionary tale. When the unit isn’t working, Barnacules pulls air conditioner out of the wall, hauls it downstairs and hoses it off in his backyard. After letting it dry out for a day, he gets the machine working again (kudos!), but this probably isn’t the best way to do it. Plus there’s foam made for cleaning your air conditioner that can be used on the machine without having to lug it up and down several flights.
