Question about Carrier Air Conditioners

Ongoing a/c issues

We have a system that is almost 5 years old, but it has never worked properly in heat waves. Right now it can keep up at 70 degrees setpoint with 80-85 outside. The last couple of days it could not keep up the outdoor temp was 95-98 and indoors we were 76-78 and humid...I had Sears come out to give us an estimate to upgrade the unit, but they said it is sized properly...Help!

Wow! a 20 degree difference from inside to the outside? That is pretty amazing for a unit to operate that efficiently at such a high temperature. If the unit is cooling that well, it would also be dehumidifying. But at that high of an ambient which probably occurred between 4PM and 8PM, the peak heat of day, no a/c is going to do any better than that,(that I am aware of). Save your money, strip down to your skivvies, jump in your pool,have a cool drink, relax, and be thankful you have such a wonderful a/c.
If this advice works for you,please acknowledge your satisfaction by giving me your rating opinion,(and an invitation to your house when my a/c quits working above 96 degrees...LOL)

    Well now, let's see here! Firstly, you provided me with NO information concerning the size or type of a/c unit, area you are trying to cool, changes in your lifestyle in the past 5 years, the region you are living in, the actual humidity percentage, etc. I gave you a solution based on refrigeration theory, that is, cooling is the result of removal of humidity and subsequently, the lowering of temperature, i.e. a vacuum. According to your statement from Sears, your current unit is sized properly. Is your house like your neighbors? Do you live like your neighbors? I think not! So, let's not compare apples to oranges or we will get nowhere!!

    Like I stated earlier, if your temperature is 20 degrees cooler than the outside, your unit is working absolutely fine. Therefore, your chief complaint would be that of the humidty level being too high.

    Now, since we have established that your a/c unit, (central air, I assume), is dropping the temperature appropriately, but not quite to your satisfaction, because of the humidity, let's refer back to the word "vacuum"! With an a/c unit of any kind, you must have a tightly sealed environment for it to work perfectly. This is sometimes an impossibility in some older homes. Newer homes are sealed more tightly to conserve energy, and thusly an a/c unit should be able to perform optimally at higher temperature and humidity levels. So, once again, not knowing the exact parameters of your existence, leaves me to believe that the Sears guy did not size your house right, (doubtful), or you have a scenario that is allowing some of that hot air and humidity to seep back into the house. This will keep your temperature a few degrees higher than your neighbors, and the humidity will also be higher because of the air leak. This will cause your a/c to work harder and be less efficient. Find the air leak, seal it off, and your problem is solved. It seems as obvious as the whiskers on my face that an air leak is your problem.

    Do some investigating and let me know what you find, I am curious to know.

The unit is on Heat, Fan Auto it's 36 degrees outside, Thermostate set on 73 Actual temp inside 70. Unit runs continuously. How can I get more heat. I tried Emergency heat and that doesn't help.


Have you cleaned the air return filters ? Wash them, don't vacuum or brush them. It damages the filter screen. Sometimes a thermostat will be out by a few degrees. If the filters are clean, try turning the temp down a bit to 65 degrees and see if the air con shuts down. ( If your room temp is showing 70, it should switch off the machine) If it doesn't turn off, keep reducing the temp by 5 degrees at a time and wait a few minutes each movement to see if and when it shuts down. If the machine keeps running, I would suggest your thermostat is shot and you will need a new one.

Make sure the capacitor is the proper microfarad rating for the motor you have. Sounds like the motor may be drawing too many amps and dropping out on it's overload when hot, then when it cools it turns back on.

You will need to have a HVAC tech to check your Heat Pump..... It is not working or not heating properly....And you are heating the house with the electric heat strips which will make your electric bill double The electric heat strips are there as back up if the heat pump is not working or keeping up with the heating demand.

I have a two year old central goodman air conditioner. The air out of the regrister is about 70 degrees I called repair and the man said that the freon and readings were ok. He thinks it might be in the...


Hi, the repairman did check the freon pressures? You should have a T D of 18 to 25 degrees F. at the supply and return air vents for it to be right. This is a 3 ton unit. Yes, if it were low, you would have ice forming on the evaporator coil. He should have been able to give you the correct answer when he installed his gauges telling what the internal pressures and system was going on. You may have a restricted txv, but he would have known this. If you paid for a service call, and they didn't know the answer, call them back out to make it right. I would have to know the readings to give you the right answer. It sounds to me that the superheat is off, but I don't know as I am not on site. Please, call them back until they find the problem, no charge to you either!! T D is the temperature difference between the supply and return air. Please keep me posed on this. Even though this unit is only 2 years old, this also could be faulty valves or a valve plate in the compressor causing it not to pump like it should. They need to send a different tech out to find out the problem for you. I wish I were on site, I could give you more, but someone is guessing??

PS, your coil needs to be at 38 to 40 degrees f.

I have my thermostat set to 75 degrees however my house will only get up to 70 degrees. At night when the temp drops outside so does the temp in my house. For example I had my thermostat set for 75 degrees...


How old is your system?

If your system is a heat pump and is failing to keep up overnight during the colder weather. Or if it struggles to keep up at all, a few issues come to mind.


Obviously, the first and most common cause would be due to an undercharge of refrigerant. With an undercharge, your heat pump has lost efficiency and cannot properly remove heat from outside.


Other possible issues that come to mind are failed defrost cycle. If your unit is not defrosting properly and it continues to run non-stop, a freeze-up could occur on the outdoor coil. And the worse it gets, the worse your system will perform.

Another possibility is auxiliary heat or heat strips are not coming on at all. Depending on your thermostat, you would be able to tell if the thermostat is calling for auxiliary heat. If you are not getting any additional heat, then the heat pump may not be adequate for the space intended.


Other smaller factors may come into play such as incorrect defrost cycles. Possibly a mechanical component taking a break or overheating or maybe a mechanical failure such as failed compressor leaving the only heat you have as emergency.

I have a CPLE24-1 split system. heat not working


I dont know where you are located but anything bellow 45 degrees a heat pump does not put out much heat. As it gets colder the effeciency goes down. So if you have 24,000 at 60 degrees outside at 45 it is 15,000. Now first thing have the charge checked. If a unit is one pound low it can loose 20 %. Next see if your auxilary heat is working . You have at leat 8 KW backup heat.This comes on the second stage about 2 degrees or 2 to 4 minutes behing the Hat Pump. Ask service tech for free estimate or call and get season check. They will go thru your unit and check everything and let you know what wrong and also clean the system. Cost about 49.00 to 69.00. I own a business and we sell a maintanance contract for 105.00 and check and clean the system twice a year.Keep in touch Rus

Indoor unit temperature between 60F & 70F after R22 charge..


The pressure changes with temperature, it is not a true gauge to ensure a proper charge.

You should have a 15 to 20 degree temp drop across the evap coil. (return air vs supply air)

Can you verify that the compressor is running?
Not the condenser, but the compressor located inside the condenser (outdoor unit)

it really sounds like it is still undercharged.
Check the temp drop, let me know what it is.
Also tell me what the outdoor ambient temp is.

( for example.... 98 degree outdoors with 85 degree indoor temp could result in pressures something like 325 on the high side and 75 or 80 on the low side.
With the exact same unit, but 80 degree outdoor temp combined with 70 degree indoor temp, your pressures could read 215 low side and 55 low side. Not to mention that more efficient units often have higher pressures on the low side because they have more coil space and remove heat more efficiently)

Temperature varies 13 degrees around setpoint on aux heat


I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.
