i just had my air conditioning system cleaned out because it was n't working right . wow , the junk that came out of it was awful . the owner before me never used filters . did you call him to complain about that ? no , since its my house and they missed it in inspection , there was n't much i could talk to him about . it was gross . dirt , dust , and gobs of pet hair . i was breathing it the whole time ! that 's awful , my air conditioner is cleaned thankfully .
