Question about Intertherm P3RA-036K Air Conditioner

1 Answer

Will not heat below 40

When unit recycles, outside cold air is pumped in. Cold spell last week, duct temp went from 94 to 70 for recycle then on down to 45, till compressor kicked in again, has done this since new, no ones figured it out yet, runs great from 40 up and in cold mode. Seems to me either big scroll fan should shut off or heat strips stay on during recycle

Thanks

Heater will not activate until outside temp. is above 40 degrees


If you have a heat pump the compressor is locked out below that temp. If you have a dual fuel - hp/gas, the gas burners should come on as would the electric heaters if you have electric heat as backup.

Hi,My remote do not get the good temp in my house. Ex: I set to 80F in heat mode but the thermopump operate slowly and dosn't get hire than 70-72F. The remote see the unit and all. Is the sensor in th


You have a heat pump.
Once the outdoor temperature falls below 36 degrees, heat pumps will sharply lose their ability to heat.
If you are getting a 72 degree indoor temperature when the outdoor temperature is 28-30 degrees, the heat pump is performing up to spec.
On heat pumps, the air coming out of the nearest air vent to the unit should be heated approximately 40 degrees warmer than the air entering the unit.
If you have a 70 degree indoor air temperature, the heat pump should be supplying 110 degree air at the closest air vent to the indoor unit.
Gas heat is a much better heating source where outside temperatures are commonly below 36 degrees.
Even electric furnaces perform better than heat pumps under these conditions.

I just turned on my liftime infred, the power light goes off and on but heat comes out on eco........Do I need to have the time set. Or does the thermostat take care of the off and on.,


Unless the system was ever programmed to turn on and off at set times,-- the setting of the clock shouldn't interfere with its putting out heat.

Is this a heat pump / AIr conditioner unit? and is it real COLD outside?

Here are some comments on heat pumps:

Remember, for an air conditioner to PUT OUT HEAT-- (as HEAT PUMP) -- there has to be some HEAT outdoors, to make the process work...
So-- ask yourself-- How cold is it outside?
How cold was it outside, the last time that my AC worked good as a heat pump?


Possibly the coil outside is all frosted up?--

Shutting it off, and letting the outside coil defrost might help-- but-- the basic law of physics still stands: To get heat inside-- there has to be some heat outside! (Likely your unit won't give you much heat inside, when it is below 50 -- or for sure-- below 40 degrees outside!)

Give us a few temperature readings- inside and out, and then gives us clues as to what is running, and what is not-- maybe we can trouble shoot deeper. Is the compressor running?-- does it sound like it is actually working-- or just running-- sort of like 'running but not really WORKING'?

Let us know--

I have a Lennex heat pump unit which was installed in 2008. Our area (Savannah, GA) has experienced some abnormal cold temps lately. Yesterday, I noticed the outside of the unit had frost on the unit. ...


Heat pumps are the same as an A/C unit only it works in reverse. Instead of blowing cold air inside and hot air outside it blows hot air inside and cold air outside. The heat being blown inside is extracted form the cold air outside. Its called Latent heat Latin for hidden. Believe it or not even though its 20 degrees outside there is still heat in the air. Example if you want to drop the temperature of a freezer from 20 to 10 degrees you have to remove heat .I know your getting unusal weather and that is the problem. Heat pumps can only work no lower then around 20 degrees outside.Heat pumps are never used above the freeze line. With your unusal temperatures thats basically where you are now. Ride it out. When your temps rise a little your be fine. Im in Chicago.

Heat not rising above 62


It sounds like you have a 'heat pump'?-- and you are trying to heat in these cold snaps-- when the outside temperature is down near freezing?
If so-- Heat pumps do not work well that cold!-- so if your system was marginal at heating, when the outside air is 40 or 50 degrees F-- you quickly run out of 'heat' in the cold outside air, to move the refrigerant in the heat pump with any heat wrung out of the COLD-- to bring heat into your house!
Make sense?

Please tell us more-- like how your heat pump worked last year, etc.

REPLACED BOTH ELEMENTS GOT HOT WATER FOR 1 SHOW THEN IT GOT COOLER AND COOLER AND NOW ITS COLD ONLY?


Find a reputable HVAC contractor to do a room by room analysis with heat and cooling loads calculated and units sized and duct requirements and compare to what you have.

The air not being cold is not necessarily an indicator of anything malfunctioning. High efficiency units for instance don't produce cold air.

Since you have had someone look at it, the duct work may be collapsed which restricts air flow or uninsulated which warms up the supply air. Either one is a possibility. Any Cox Cable guys been stompin' around your attic lately? Wouldn't be the first time.

Usually, when the air coming out of the vents is not cold enuf it's because your freon level is low. Probably leaking, but they can usually recharge the freon and it will work for a while. Try another repair company and see if they can recheck the freon level.

We have a high efficiency unit and it produces cold air, so I don't know what previous poster is referring to. Air conditioners are supposed to blow cold air.

Sorry, to tell ya but it is normal if the outdoor temperatures are much below 45 degrees. Below 45 degrees there is little heat outdoors for the heat pump to grab to heat the home so it will run 24/7 and blow cool or cold air. Below 45 the temp of the air coming out the vent will decline and you will get no heat from the heat pump itself as you near freezing.

Your emergency heat or auxiliary heat is electric strip heat. But it only kicks in during normal operation if the temp in the house drops 3 degrees below the setting. (some tstats if can be 5 deg.) Otherwise the heat pump will blow cool or cold air the rest of the time if it is too cold out.

To prevent it from running all the time and blowing cold it is recommended if the temp outside is falling below 45 degrees you should just switch to the emergency heat setting, which shuts the pump outdoors off, and just heat with the electric.

But if there is no heat outside the heat pumps will blow cold. They are the cheapest and most efficient forms of heat but only as long as the outdoor temp is above that 45 deg..

I'm guessing that if you haven't experienced this you live in some place with moderate winter temperatures like in Northern Florida and rarely get very cold winter temps like the freezing you have seen there recently.

It will likely blow much warmer when the outdoor temp rises.

The heat from my aircondition is soo intence that my room becomes hot rather than cold air


you need to direct the hot air coming out of the unit out of the room and the cool air into the room. You need to run a duct or tube from the condenser side to outside. Otherwise it is just recycling the air and adding heat from the compressor.

The last couple of days our heat pump will not cool below 80 degrees even if we set the temp to 65. The unit keeps running. last week the heat pump worked very well. The unit is 10 years old.


Check the outside unit. Feel the larger line to see if it is cold. Is the condensor dirty. If you have a way to measure temp. Take the return air at the filer and the closest grille temp and subtract. It should be between 19 to 23 degress. If not you have a problem. Could be refrigerant or some other problem. Either way you need to get it checked out by a service tech. Ask for free estimate that way you are going to know how much it cost before hand. Rus
