Parts of an Air Conditioner You Need to Inspect Regularly

All households that experience warm and humid weather, especially during the summer, require air conditioning units installed in their homes. That way, they can look forward to receiving good quality indoor air, remain comfortable and relaxed, and avoid experiencing difficulties.

However, if your air conditioning unit breaks down, it will be hard to take care of the problem on your own because you may not have enough knowledge or experience for it. When you fail to maintain the excellent condition of your air conditioning with the help of an expert, you increase your chances of facing costly repairs and replacements down the line.

Even though your AC unit seems to be in good shape, you may not know what’s happening deep inside it, so it’s still important to call for maintenance every once in a while. Other than that, you should also know how to take care of your cooling system on your own. Keep reading below to learn the vital components of an air conditioner to avoid facing sudden issues.

Air Filter

One common reason your air conditioner isn’t working at its optimal capacity is that its air filter is dirty and in need of cleaning. Over time, a buildup of dust, dirt, and other floating particles can get trapped in an air conditioning’s filter and reduce the unit’s performance.

If you want to take the matter into your own hands, you should read your air conditioner’s manual or reach out to the manufacturer to find out when’s the best time to replace your air filter. Depending on what they recommend, it can be every month or a couple of months, while other air filters will only require proper cleaning so you can reuse them for your AC unit.


The thermostat is an integral part of maintaining the high-quality indoor air you’re receiving from your cooling system. It’s what keeps the well-balanced temperature you set your air conditioning on at home.

If you want to guarantee you continue benefiting from your AC unit, you should look at your thermostat to see if it’s on first. Inspecting if it’s clean, ensuring it’s set on the right level, and keeping it away from direct sunlight are all necessary to preserve the upkeep of your AC.


A coolant is also called a refrigerant. It’s a part of your air conditioner that tends to leak and affect the overall performance of your cooling system. When that happens, you can expect your unit’s temperature to act up, keeping you from acquiring the proper air quality you need to remain comfortable indoors.

Depending on where you can find the leak, it could impact the air conditioning repair costs and weigh heavily on your savings. If you want to avoid addressing unnecessary expenses, it’s best to call for maintenance every year and let a professional technician do their job.

Drain Line

The drain line or drainage of an air conditioning can also experience the same problems as an air filter. After a while of benefitting from your AC unit, the drainage can start to collect dirt, dust, and other grime, ending up clogging your system.

When the buildup becomes too much for your AC, the drain pan will fill up and result in a leak. Water will come out of your air conditioner and eventually lead to damage not only on your cooling unit but also on what’s positioned around the pan.


Your air conditioning system consists of various parts, and the air filter, thermostat, coolant, and drain line are just some of the essential components you should take time maintaining. It’s vital to inspect your AC unit regularly to guarantee there aren’t any problems present. If there are, you should notify a technician right away while it’s still early to prevent major repairs.
