3 Common AC Problems You Can Fix Yourself

When your AC unit is working properly, it easily keeps your home at a comfortable temperature, even when it’s sweltering hot. Therefore, there are few worse things than discovering your AC is not working properly on a hot summer day. It’s best to confront problems before they become an issue, so we outline a few of the most common AC problems, how you can identify them, and how to fix them.

Your AC Won’t Turn On

If you have a central AC unit, the first thing you need to do is check your thermostat and ensure that it’s set to “cool” mode. All external wiring should be inspected to make sure it’s intact, as animals chewing on them can sometimes damage them. Does that all check out? If so, look at the electrical wiring in your home as your next step, as you might have blown a fuse or tripped circuit breaker. Resetting the power in your home can help fix the issue.
If you are still having issues with your AC not turning on after those fixes, you might have a problem faulty internal wiring or a broken motor. In both cases, you should contact an HVAC technician to examine your unit and appropriately correct any issues.

Your AC is Not Cold

If no cold air is coming out of your AC unit, check the thermostat and make sure the proper temperature is set. One trick is to lower the temperature by a few degrees, and if there is no noticeable difference, then the problem might be a clogged condenser or evaporator. Turn off your unit and carefully clean out any noticeable dirt or debris, as the build-up of dust or debris such as weeds, leaves, dirt and pollen prevent the cold air from entering your home. Ensure that the coils and fins of your condenser are clean so the air can flow properly. If this doesn’t fix the issue, then you should contact a professional.
Another possible problem might be that your unit has a refrigerant leak. To check if this is the problem, inspect the set line and look for any damaged areas, and do a visual inspection of the inside and outside connections. If there is a wet spot somewhere, this means that there is a refrigerant leak, which an AC technician must fix.

Your AC Conditioner Fan is Not Working

If the conditioner fan in your AC unit isn’t working, you need to check your electrical system and ensure that no switched off the circuit breaker or tripped wire is causing the problem. Next, check your AC unit for excessive ice buildup, which could be causing the fans coils to freeze. If you notice that is the case, then you need to shut off your unit and contact an HVAC technician.

Your AC Has Mold

Mold in AC units is a common problem, but it’s a serious one, as it can be a detriment to your health. Unfortunately, fixing this is not something that you can DIY, so your best course of action is to contact an HVAC professional. They will have the tools and knowledge to tackle this problem and keep you healthy and happy.
