I went through a few strange local heating and air conditioning contractors before finding a qualified expert, and I mean, all these people claim they are experts… But you can’t constantly take their word for it. It usually depends on the individual, however some people could go to heating and air conditioning college for a long time plus not learn enough to be a tploy professional. Some of these guys, I wonder if they cheated on their heating and air conditioning certification exams, because you do have to pass those tests in order to be fully qualified… But anyway, none of these people were able to help me and others out with my problem with overpriced energy bills, so nobody provided myself and others any energy saving tips or anything… They didn’t even check the whole of the heating and air conditioning system, plus I’m talking about the air duct included. It wasn’t until I finally was referred to an actual heating and air conditioning expert who diagnosed his own, then he said he really did not have an overwhelming amount of buyers, although he hoped he would acquire more contractors in the future through word of mouth advertising. I thought that was kind of an outdated way to get the word out about your business, but this guy seemed confident in his skills. He was the real deal, he diagnosed everything plus he also diagnosed the pressure of my air duct system. He explained that the pressure reading told him what he needed to know. He diagnosed the air duct carefully plus found there was a leak as he suspected. He said this was an immense reason for my energy loss plus high energy bills. He performed the air duct sealing plus showed that my pressure was back to healthy levels. He also provided myself and others with some helpful energy tips, and cared about using cooking devices other than the stove in the heat of the warm season.
