How often should I service my air conditioner?

In today’s world, an air conditioner has grown to be a necessity as opposed to a luxury. For many, it is one home/office appliance that they can’t do without over the long summer months. The cooling breeze of an air conditioner has saved many from suffering a heat stroke and other heat-related health problems.

However, as important as an AC may be, we sometimes forget about it once the summer is over. Admit it, sometimes you don’t even remember that you own an air conditioner until the weather is hot again. This should not be so. It is better that you maintain your air conditioner throughout the year.

When it comes to maintaining air conditioners, there is one question that most owners always ask – “How often should I service my air conditioner?”. Depending on the age of your air conditioning unit as well its frequency of use, there are acceptable periods when it should be serviced.

If your goal is for your air conditioner to remain in on top working shape for a long time, then you should service it at least once a year. Under ideal circumstances, servicing should be carried out in spring, before you have to start using it consistently again.

Servicing your air conditioner is not a big ask. All you have to do is schedule annual checkups with a professional HVAC company, and you are good to go. Of course, you may be hesitant to spend all of that money for “no reason.” But, it may end up saving you more money in the future.

In time, you will come to find out that paying to have your air conditioner serviced regularly is cheaper than shelling out big bucks for substantial repairs or a new air conditioner.

Are you still unconvinced? Keep reading as we answer any niggling questions you may have about air conditioner maintenance.

Why is air conditioning maintenance necessary?

Servicing your air conditioner is not some far-fetched scheme to get you to spend money. It holds a lot of benefits that will ensure you enjoy the services of your air conditioner.

1. Increased dependability

If you service your air conditioner at least once a year, you will have reduced worries about it developing a significant fault when you need it the most. This is because any probable problems with your AC unit would have been tackled during its servicing.

2. Saves you more money

If any small problems are noticed by your HVAC specialist, they will be fixed before they turn into more significant issues. This is the primary way that regular servicing of your air conditioner helps keep your money. It is always better to have to fix a leak as opposed to replacing a major air conditioner part because you were not vigilant enough.

3. Reduced energy costs

If you take the proactive step of servicing your air conditioner regularly, it will be able to function efficiently. This will translate to lower energy bills. We are sure that you already think your energy bill is too much. Reducing these bills could be as easy as having your air conditioning unit serviced.

Air conditioners comprise of many small parts that all need to function perfectly well. A minor issue in one component, say the compressor, can put an extra strain on the unit as a whole. This can translate to increased energy bills. Service your air conditioner today and save more money.

4. Counteracts the effects of age

Like other household appliances, your average air conditioner has a life-span. As the end of that life-span becomes closer, your AC is bound to breakdown more often. Servicing your air conditioner at regular intervals can help you fight these faults. It doesn’t mean that you would not have to change your air conditioning unit eventually, but servicing it can help extend its lifespan.

What happens if I don’t service my AC?

Air conditioners need to be serviced regularly to ensure that they function as efficiently as possible. If you don’t maintain your air conditioner, there are a few faults that may develop. Below are a few things that may happen if you don’t service your air conditioner regularly:

1. The AC unit will collect dust

Over time, if you leave your AC unit untouched, especially when it is not in use, there is a high probability that it will collect dirt and residue. Additionally, air conditioners collect dust from the atmosphere to improve air quality. If you don’t service your air conditioner units, this dust will build up in your air filters.

This build-up of dirt and residue in your cooling system, over time, will affect its functionality and efficiency. It will have to work even harder to achieve previous results. You may notice that you have to decrease the temperature to produce the same cooling effects as before. Invariably, your air conditioner will begin to consume more energy.

Dust and dirt may be damaging to your air conditioner. But the truth is that it can also have harmful effects on your health. If you have allergic diseases such as asthma, your AC emitting dust can be dangerous for your health.

2. Worn-out parts

Air conditioning systems are complex. They are made up of multiple components that all need to be working well at the same time. There are some parts in your air conditioner such as the fan and coils that require lubrication and proper cleaning to function normally.

If you don’t service your air conditioner, these parts are going to get worn out over time and lose their efficiency. This will lead to the slow deterioration of your AC unit as a whole as well as increased energy bills.

You don’t want to find out that you have to make expensive repairs on your AC because you didn’t lubricate one part. Get it serviced today!

3. You may be aggravating small issues

Sure, you may be changing your air filters at regular intervals by yourself. But have you noticed that your air conditioner is still not working as efficiently as it should? This may be because you are fixing the wrong problem.

You may think that your AC filter needs replacement, but instead, it is suffering from low refrigerant levels. The only way to be sure that all parts of your air conditioner are working well is to have it serviced. Only a professional HVAC technician can tell what is wrong with your air conditioner.

You don’t want to be beset with a bill that could have been avoided if you had called in the experts sooner.

How often should I service my air conditioner?

The answer to this question is yearly. If you service your air conditioner on an annual basis, especially before you use it aggressively in summer, your air conditioner should serve you well.

However, there are parts of your air conditioner that may need more regular maintenance. Some of these parts are the air filters, coil fins, and compressors.

Air filters

Even after yearly maintenance efforts, your air filters need to be maintained with more frequency. Ideally, they should be cleaned at least once every two weeks. Depending on the type of filter or your rate of usage, they may have to be cleaned more frequently.

Some times, you may even find that they need to be replaced. You can do this yourself or contact a professional.


Your air conditioner has two coils that are prone to overheating if dirt accumulates on them. The evaporator and condenser coils can work efficiently with annual servicing. However, if you live in a place with unusually low air quality, they may need to be serviced more frequently.

Coil Fins

Your AC has aluminum fins that protect the coils. These fins are fragile and delicate. They need to be handled very carefully. Over time, they may start bending out of shape and eventually break. Regular servicing should keep them in perfect shape and stop them from blocking airflow.


Overheating compressors can have dire consequences for your air conditioner. Additional maintenance apart from your yearly efforts should help prevent this.

DIY Maintenance

Aside from getting a professional to service your system regularly, there are a few things that you can do to keep your air conditioner in good working condition.

First off, make certain that every vent that leads indoors is clean. You can also pour a mixture of bleach and water down the outside unit’s drain to prevent the buildup of algae and mould.

Additionally, make sure that your air conditioner is placed on a level surface. It should also have at least 1.5 feet of clearance at all times. A simple cursory look at the refrigerant lines to make sure that they are well-insulated can go a long way.

Finally, as much as possible, try to avoid opening your air conditioner by yourself. If you are not trained, you may end up spoiling it. If you hear a strange noise or detect a fault that seems to be internal, call a licensed technician to help you out.
