If your air conditioner is blowing out hot air – there is no need to immediately jump to conclusions. You also won’t need to find out if a ductless system is right for you, because you can probably fix the issue with your current central air conditioner on your own. Even if you don’t know exactly what is going on with your AC, you probably want to diagnose the problem before you automatically assume that your system is doomed. If it is doomed, you can relish in the fact that you were right. However, the problem is usually a lot easier to deal with than you imagined. Central AC systems can be finicky sometimes and even the smallest issue can cause the whole unit to malfunction. Here are five tips for diagnosing and fixing a central AC that blows hot air.
- Perform a visual test. You can usually open up your air conditioner and, like a book, discover exactly what is wrong. There may be a glaring issue, like a wire that is burned out. You also want to look at the condenser coils. If they have frost or are completely frozen, there is a good chance that your filter is clogged. When a filter is clogged, it causes your system to work on overdrive, which can freeze your coils and cause warm air to blow out.
- If your filter is clogged, you can simply swap out the filter. Finding a filter is usually a matter of visiting your manufacturer’s website that then purchasing a new filter for your unit. Once you get your new filter in the mail, you can simply take out the old one and put the new one in. Typically, swapping out the old filter is easy – you just pop it out, but it may require some unscrewing.
- Turn your AC fan on for at least four hours. Letting your fan blow will allow you to melt the condenser coils after you have swapped out the old filter. It is recommended to turn on the fan at night, so that by the morning your air conditioning system will be in working condition again. This can be especially helpful in the summertime when you need the cooling power of your AC during the day.
- Don’t forget to inspect and clean your air ducts. The benefits of air duct cleaning run the gamut, but when it comes to your air conditioner blowing out clean, cool air – a good cleaning is vital. Not only that, but a cleaning may also reveal a leak in the ductwork, which is important to seal if you want your AC system to work efficiently. Sealing a leak is as easy as patching it up with tape and epoxy resin.
- Clean out the outdoor unit of your air conditioning unit. After you swap out the filter and clean your ductwork, you want to be sure to remove any detritus from your outdoor compartment. This is usually where your fan is, so you want to remove any large leaves, twigs or debris that may have fallen inside. The last thing you want is a broken fan blade, because it could compromise your whole system.
