Is there anything as a home owner I can do as far as the cleaning of the unit as the other guy said? I do not see where there is dust in anything other than the normal dirt and grim from it setting outside.
I think I will call the carrier people and have them come out and have a look at it...
You need to call a *COMPETENT*, licensed, insured, professionally trained, HVAC technician to come correctly diagnose and correct the problem with the system. No he is not gonna be the cheapest price, but then knowledge and quality doesn't come cheap. Tell that other "sales-nition" to hit the road and find another sucker.
