Summertime is a great time to relax and enjoy the weather. However, it’s also when you depend upon your air conditioning unit to keep you cool indoors. Should it decide to malfunction or break down, it can quickly turn into a nightmare. In this article, we’ll discuss 6 common air conditioning problems and how to properly fix them.
What Are Air Conditioning Units?
Air conditioning units are devices that remove heat from an area to cool it down. There are several different types, including:
- Central air conditioners
- Window air conditioners
- Portable air conditioners
The most common type is the central air conditioner, which is used to cool large areas, such as office buildings and homes.
If the air conditioner is leaking water, it could be because the drain pan is full or there is something blocking the drain line. The pan should be emptied and the line should be checked for any blockages. If the ductwork isn’t properly sealed it can leak as a result, so the ductwork should be inspected and any leaky areas be re-sealed.
If any such issues persist, they could be due to a more serious problem and the air conditioner should be checked by a professional. If you contact an HVAC company you can request a free estimate online and receive help with AC repair and replacement, or emergency AC services. Whether it’s commercial air conditioning, heating, or ductless mini-splits you can often read customer reviews before getting help.
2. Strange Noises Or Bad Smells
This could be because the fan blades need to be cleaned or oiled. The coils may also need to be cleaned if they’re covered in dust or dirt. Some other causes include:
- The fan blades may be hitting something
- There may be something caught in the fan
- The compressor may be starting to fail
- Loose parts may be rattling around inside the unit
If you ignore these strange noises, it could lead to bigger and more costly problems down the road.
If your air conditioner is giving off bad smells, it could be because of a clogged filter. Try changing the filter to see if that solves the problem. If not, it could be coming from mold or mildew inside the unit. In this case, you’ll need to call a professional to clean it out.
If your air conditioner is overheating, it could be because the coils are frozen. This usually happens when the air filter is dirty and needs to be replaced. It can also happen if there’s not enough clearance around the unit, which prevents proper airflow.
To fix this, simply clean or replace the filter and make sure there are at least two feet of clearance around the unit.
4. Turning On And Off Frequently
A dirty air filter restricts airflow and causes your AC to work harder, which can lead to frequent cycling. The solution is simple: just replace your air filter! Depending on the type of AC unit you have, you should replace your filter every 30-60 days. If you have pets or live in a particularly dusty area, you may need to replace them more frequently.
Another possible reason for frequent cycling is an undersized unit. In this case, the only solution is to replace your AC unit with a larger one.
5. Inadequate Cooling
Make sure that all the vents in your home are open and unobstructed. Check to see if the thermostat is set to “cool” and is turned down to a temperature lower than the current room temperature. Finally, take a look at the outdoor unit of your air conditioner to see if there is anything blocking the airflow.
If none of these solutions solve the problem, it’s time to call a professional. Air conditioning specialists will be able to quickly diagnose and fix the issue for you.
6. The Unit Freezing Up
One common issue is when the air conditioner’s evaporator coils freeze up. This can happen for a number of reasons, such as when there is inadequate airflow over the coils or if the refrigerant charge is too low. To solve this problem, you need to thaw out the coils and then check for any potential issues that may have caused them to freeze in the first place.
These have been 6 major issues you may encounter with your air conditioning unit. Be sure to perform regular maintenance and book an annual service. Get help where you’re unsure because this will prolong the unit’s life and maximize its efficiency.
