How often should you clean the air conditioner filter?

I think I am lazy, so I don't often clean the air conditioner filter. When it is dirty, then the air conditioner will give me a signal and show the red light. When I see it, I know it's time for me to clean the filter. Last time I cleaned it was about a few weeks ago.

I am not a an aircon technician but we usually cleaan the filter at least every 3 months. Thats helping clean the air we are also getting from it. I suggesst that at least you must put off one of the aircon after 8 hour use and vice versa with the others. If you still felt hardness breathing indoor I suggest that you call on your seller if it is under warranty and/or call a technician if there is a need to.

I think if you DON'T clean the air filter it will mess up your air conditioner. I live in an apartment, and the maintenance man cleans or changes all of our filters every other month. I've been in houses that didn't clean the filters, and the air is very heavy.

If you don't clean the filter or get new filter then you are asking for problems with your A/C. We also live in the south part of Texas and have central heat and air but mostly use the air. We change our filter at least once a month, it depends on what type of filter you have whether or not you can clean them or need to replace. It does help that our son is int he A/C business to keep ours running in good condition. It will never harm your A/C to clean the filter even if it is too often. If you have the type of filter that you can wash and reuse for a certain amount of times remember not to put it back in until it is completely dry. I hope this helps some.

i have no air conditioner, so i dont need to do it at all. but there are three air conditioners in my parents' house, and my mom often clean them once a month in summer. but we dont use air conditioners in winter, so my mom clean them once in 3 months. frankly, there are more electrical equipments in my family, but i have to do some clean for them every month. and they are often hard to clean.

I've always been told once a month or when needed.I used my vaccum to clean them out also.
