Change the air filter?

I hated knowing there were troubles with my a/c unit.

Whenever there was anything wrong with the Heating plus Air Conditioning system, my partner tried to blame me.

The last time there was a problem, the Heating plus Air Conditioning corporation said it was because of a clogged air filter. There was no airflow, plus it had caused the heat exchanger in the boiler to crack, then my buddy and I had to buy a new boiler, plus my partner wasn’t blissful. He told me I should have known something was wrong, plus called the Heating plus Air Conditioning corporation earlier. I wasn’t the one who fiddled with the boiler, plus he should have known something was wrong. This time, my partner wasn’t home when the Heating plus Air Conditioning corporation arrived. He told me the problem my nice friend and I were having was because of a clogged air filter. I knew there was an air filter in the boiler, despite the fact that I didn’t know there was one in the AC unit. He told me the air filters needed to be changed at least every six weeks. It was the first defense against breakage plus clean air in the house. He told him up until this winter, I didn’t know there were air filters in the Heating plus Air Conditioning system. If I didn’t know they had them, how could I change the air filters? He had me go outside with him, plus he showed me where the air filter was. He then had me remove the air filter plus showed me how to officially insert the new one. If the task is that self-explanatory, I was sure I could do it, but not in the boiler.
