William called 30 minutes before coming to house. Was early in morning before heat of day started inside house (such a relief, I had family from out of town visiting who not used to Texas heat). Got AC up and running, gave me some very helpful tips to maintain my outside ac units (clean coils with water hose) and also explained to me about air filters ( I had been using two for one unit but since the one by blower a 5 inche thickness it not necessary to use the other one I had been using. Friendly, helpful. Offered and explained other John Moore services as well. Thank you
