This is in response to Matt S's question a few days back. I feel like most of the answers were a put down and I am experiencing the same problem he is. It is not the temperature of the house or where the system cools it to that is the problem. The actual air that blows out is the coldest in the "normal range", as tested by an A/C company, and its freezing to me. Many places in the house that I sit or stand are under a vent. I have owned several houses and additionally rental properties and have never experienced this before. Like the comments here, the overweight AC guy shrugged and said he doesn't hear people complain the AC is too cold. Well, for me it is to the point where I want to put the house up for sale it is so unbearable. If replacing the unit is the only way to solve it I will do it (it is 10 years old), otherwise if someone has a friendly suggestion that isn't "unrealistic expectations" please help. Thanks!

    That sounds like a problem with the vents. Possibly a problem that was induced by a previous owner who liked it that way. – Harper - Reinstate Monica Jun 14 '17 at 1:43

    Blower speed can often be adjusted. – Tyson Jun 14 '17 at 1:50
  • @Tyson that's more complicated than simply changing the speed. It's doubtful that the average homeowner has the tools or knowledge, required to determine if it can be adjusted. – Tester101 Jun 14 '17 at 2:44

    @DavidTrietiak what about diffusers, or deflectors on the vents? They could be installed so that the air doesn't blow directly on you. Would rearranging the furniture be an option? – Tester101 Jun 14 '17 at 2:46

Air too cold---I would measure the temperature drop across the evaporator coil in the furnace/air handler. If it is more than 20 degrees then moving more across the coil is necessary. Usually this could be done by increasing the blower speed. If you do not know how to do this call a good service tech to help. If the furniture is arranged so the discharge vents blow on you when you are sitting there, then you need to change the way the cold air enters the room or move the furniture. And not to slight Jim but I have never heard of raising the evaporator temperature by adding more refrigerant and overcharging a system has never been a good thing; ( if I am wrong let me apologize in advance). There could be other problems such as the A/C system is too large for the house, not enough supply registers allowing too much air to be discharged from those registers, poor placement of registers, the ducting is too small causing the air velocity to be higher than normal or there is too much air coming from the registers. But first start by measuring the temperature drop across the coil. Hope this helps

    My comment recommending adding refrigerant to slightly overcharge was one of those "think outside the box" ideas that are usually wrong but are perhaps thought provoking. You are right to question it and personally I wouldn't do it; I would never use anything but the optimum charge, but I love cold air blowing on me. I sit at the kitchen table right under an a/c vent with 58 F air blowing on me. – Jim Stewart Jun 14 '17 at 15:19
  • One possibility is that the filter is too restrictive and is restricting the air flow. If someone has put on a "special" filter designed to stop small particulate matter this might be reducing the flow rate. A filter which is too resistive to air flow can shorten the life of the blower motor by overloading it. – Jim Stewart Jun 14 '17 at 15:21

actually your ac is a oversized one so it makes too much cold.On your other hand your other houses have properly sized ac.
