Hi,

I have a carrier central air with gas furnace. The air is cool from the vents but I like it cold like on 62 to 58 degrees. I set it but it runs for several hours but not going down to my desire temp. I run the fan cotinuosly. Please tell me how I can get it cooler. Oh its 2 years old.

62 to 58 degrees is pretty cold for a household a/c,, has it or did it ever get house that cold to satisfy the thermostat and keep/hold the indoor temp. at that setting? That's working a condenser unit awfully hard.And yes I woud say it probably does run a lot if not all the time.. most household units are very lucky to keep the indoor temp. 15 degrees ,20 degrees at the most cooler than the outside temperature

wmproop is correct. You will never get a residential ac unit to keep these temps. Most people are asking for heat when it hits 62 degrees. I would suggest putting an accurate thermometer directly in one of the supply vents. If you get a reading of 15 degrees less than the room temp, than your ac is working just fine. Sounds like you are asking the impossible from a residential cooling system. Sounds like you need to convert your house into a walk in cooler.lol

I think that a residential cmpressor should work can't the company make a compressor that is good and can get the air down to 58.

bsaah · Oct 18, 2008, 06:12 PM

Uno that some people like it cold.

mygirlsdad77 · Oct 18, 2008, 06:14 PM

What is the temp outside?

wmproop · Oct 18, 2008, 06:20 PM

I would send the request to Carrier,ask them to special build you a unit to do what you need/want,maybe if you board up all the windows and put 8 to 10 inches of foam insulation around all your walls ,in the ceiling and the floors it would help what you have

bsaah · Oct 18, 2008, 06:20 PM

Like 40 degrees

bsaah · Oct 18, 2008, 06:21 PM

No I am saying like in the summer uno.

bsaah · Oct 18, 2008, 06:22 PM

wmproop what I'm just saying that they should put that as a option. Im not saying they should.

mygirlsdad77 · Oct 18, 2008, 06:58 PM

You can have anything you want. But I guarantee, that if you want it to be 58 degrees in the house when it is 90 plus outside, it is going to cost you more than you want to spend. Ac units are not magical. Just for giggles, when do you turn your heat on, what temp are you comfortable at during the winter?

KISS · Oct 18, 2008, 07:41 PM

I think you guys missed it. The AC would need to be oversized or sized for the desired indoor temperature. This would change the Manual J calcs, but you should end up with the right size for the desired indoor temp.

Your AC is working effectively if the outlet temperature to the evaporator is between 15 and 20 degrees.

Sounds like the OP wants a walk-in refrigerator.

mygirlsdad77 · Oct 19, 2008, 06:48 AM

I'm my experience, if you over size too much, you will have problems with freezing evap-coil, there for you would have to over size the furnace and duct work to get correct air flow, like I said, it can be done, but its going to cost a bit to do right. Residential AC is condidered a high temp refrigeration. Only designed to do so much.

I think that oversized Air condtioner for a residential house is going to cost you a fortune. + I think that its high maintenance. Oh well My heat is at 73 right now it is very good temp. In the summer I like it cold. And in the winter I like it hot. Don't ask me why but I do. I think that the freon should be charged in the unit every 5-6 year depending on how much you use it. I use my ac extesively. So I Don't know how much freon I use. Plus in the heat pump is very good at cooling but sucks at heating. I think that carrier should make a option were a packaged. Plus you need to know the right size return probably a return for every room. I think that putting four rigister in a room. Regurdless of the size of the unit. I know somebody that his room is cold through year. So he has to put the heat on 78 ( Gas Furnace) And he like it hot. Year around to when I like it cold year around.

Regurds to this conversation I think that The air should be cold. Oh how about it pulls the from outside when its cool like a cool pump sort of typa.

Sincerely,
bsaah

You should never have to (recharge) you ac unless there is a leak. If there is a leak it must be fixed. If no leak, then no need to charge. It is a sealed system. Your refrigerant should and will last throughout the life of your ac unit.

Try medium temperature refrigeration equipment, but condensation will be a big issue.
