Avoid These 8 Common AC Maintenance Mistakes

For most households, the biggest contributor to their electricity spend each month is their air-conditioning system. If you have an air-conditioning system in your house and you are not taking proper care of it, you might be paying more than necessary in utility bills. Therefore, it is important to take care of your air conditioning unit in order to make it run as efficiently as possible. Proper maintenance will not only save you a lot of money in the long run but will also enhance the service life of the AC unit.

Here are a few common air-conditioning maintenance mistakes people make and what you need to do in order to avoid these mistakes.

1. Not Checking Aircon Filter

You must be aware of the many filters in your air conditioning unit. These filters are designed to catch dust, dirt, debris and other contaminants. The more you run your unit, the more these filters are going to catch these contaminants and over time, these filters will get clogged. Therefore, it is important for you to ensure that the filters are properly inspected and replaced, as and when needed.

Dirty air filters not only affect the indoor air quality but the air-conditioning system also has to work much harder in order to maintain the temperature you have set in the thermostat. Experts recommend replacing the filters at least once every 3 months. If you do not want the expense of replaceable filters, you should consider investing in filters that can be washed and used again. The crux of the matter is that you need to make sure that the air-conditioning system filters are always clean.

2. Ignore Strange Noises

If you hear strange noises coming from your air conditioning unit, do not ignore those noises. It simply means that something is not right with your system and you need to call a professional to take a look at the unit. If you ignore those noises, the problem will become worse and you might need to replace the whole unit. Therefore, call a professional as soon as possible when you hear any strange noises coming from your air conditioning unit.

3. Not schedule a routine to clean & service the aircon

Like all other appliances in your house, you also need to maintain a routine maintenance program for your air conditioning unit. It will make sure that your unit is working as efficiently as possible. The professional performing the routine maintenance will clean the coils, replace or clean the filters and make sure the unit is tuned properly in order to ensure that it runs at maximum efficiency. Routine maintenance will not only help in maintaining the efficiency of your AC unit but will also enhance its service life. Without routine maintenance, the service life of your air conditioning unit will suffer and you will have to replace it much earlier when needed.

4. Turn on and turn off aircon frequently

If you are used to frequently turning your air conditioner on and off, it will affect the service life of your air conditioning unit. Therefore, change this habit in case you are used to frequent turning on and off of the air-conditioning unit. It puts a lot of stress on the AC compressor and it will wear out much faster than anticipated.

5. Adjust the thermostat frequently

Do not adjust the thermostat of your air-conditioning unit frequently. When you continuously change the thermostat, the air-conditioning system needs to work extra hard in order to match the temperature set in the thermostat. It will not only affect the efficiency of your unit but it will also put undue stress on the unit which could lead to emergency repairs or worse, replacement of the air-conditioning unit. Therefore, it is recommended to set a temperature that is just right for you throughout the day.

6. Not using a ceiling fan to work together with aircon

One of the most common mistakes made by people is that they do not use their ceiling fans along with the air-conditioning unit. You can save quite a bit of money by turning on the ceiling fans when your air conditioner is on as ceiling fans will circulate the cool air throughout the room and help achieve the set temperature quickly. In short, use ceiling fans along with your air conditioning unit to enhance the service life of your air conditioner and to make it run as efficiently as possible.

7. Choose the wrong aircon service contractor

Your air conditioner is a mechanical device and like all mechanical devices, it will need repairs eventually. When you are searching for an aircon professional to fix your air conditioning system, do not make the mistake of choosing the cheapest one. You might think that going with the cheapest technician you could find is going to save you money but it will cost a lot more in the long run. Professionals who know what they are doing are going to charge accordingly. You might have to pay a higher price to a trained professional but they will make sure that your air conditioning unit is properly tuned up. It will save you from emergency repairs and will also make sure that your air conditioning system is working as efficiently as possible.

8. Not replace the old system even if it has reached the end of its service life

It is recommended to replace your air conditioning system at the end of its service life. Most modern air-conditioning systems are designed to last for around 15 years when they are properly maintained. Your air-conditioning system will start developing problems with time and will run less efficiently. Therefore, it is better to replace an old system once it has reached the end of its service life. It will save you a lot of money in terms of utility bills. You will also experience more comfort as the new unit will use the latest technology and keep you more comfortable during those hot summer months.


To conclude, it is important to ensure regular maintenance of your air conditioning unit in order to make it run as efficiently as possible. You should avoid the above-mentioned maintenance mistakes in order to save money on utility bills and enhance the service life of your air conditioning unit. It is important that you always call in a trusted and reputable professional who has experience in servicing the brand you are using at home or office. If you call in someone who does not have the proper experience just to save some money, you will end up paying a lot more in the long run.
