Question about Carrier Heating & Cooling

1 Answer

Carrier Model No 42NVQ007MM inv, NO Heat output

Purchased approx 9 months ago has the above single box outside and two indoor units.Question,is this unit capable of providing a heat output with the outside temp of approx 17degrees C with a required indoor temp of say 21degrees.The installer seems to think that the problem may be that the indoor and outdoor unit 'aren't communicating' and seems baffled by the problem.There were slight problems initially with the system having to be 're-gassed' and a small leak from one of the indoor units rectified .

    hi there,thanks very much for your prompt reply,as you surmised the guy involved was an installer not a 'tech' so would you be so kind as to explain the term 'locked out on low temp', again I look forward to hearing from you.jim

Unit should be locked out on low temp and your electric heat should be running. is your installer a service tech or just an installer that could also be the problem if he is a service tech it would work correct when he left

Do I need a outside cooling unit for a Coleman 7900 Presidential lll gas heat and cooling unit


Yeah, youd have to look at the model on the Indoor coil box, furnace will be setting on top of it. Youll need the model off that coil box to get the correct tonnage of the outdoor condensing unit, you can go 1/2 ton smaller on outdoor for greater efficiency.

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

Carrier heat pump (basic model) runs at 0 or below


A basic model heat pump with an air handler with electric strip heat generally will continue to run with a call for heat regardless of the outdoor air temperature unless there was an outdoor thermostat (an accessory) installed. There is still heat in the outdoor even at temperatures of zero and below. Generally, there is a balance point of approx 30-35degF that allows the heat pump to heat your house to 68degF without the need for the electric heaters. Below that, the heat pump can still extract heat from outside and "pump" it into your house; however, it will need help from the electric heaters. In temperatures below the balance point, the heat pump will run non-stop. As the temperature in the house falls approx 1 - 2 degF below the setpoint, the electric heaters will energize. So it is not uncommon for the system to run non-stop with the temperature falling a few degrees below setpoint. The colder the outside temperature, the more often the strip heaters will cycle on/off. If your system is well-maintained and operating at proper performance, it is still cheaper to run your heat pump than it is to run on straight electric heat. If you live in a climate where below zero temperatures are normal during the winter months, you might want to research heat pump options that offer higher COP's and increased performance in colder temperature than the basic contractor's model. Start with initiating communication with a local contractor. You will need to consider initial cost and the pay-back period based on your local energy costs and your specific demands you want your system to meet.

Hope this helps!

Carrier heatpump model 25hba324a300 unit will not supply heat.outside unit constantly comes on and goes off .works well in a/c mode.


may be cycling on high pressure switch. is your filter clean? also that is a 13 SEER unit was the indoor unit replaced at the same time? if not it may not be compatible causing higher than rated pressures. if the ac is working then i would rule out it being a low pressure problem

if your system is a heat pump you can switch to heat and see if coil outside gets cold while indoor blows warm air - then switch back to a/c - both coils should not be cold at the same time - low freon pressure / dirty coil / dirty filter / low air flow causes freezing

Hi- Can not tell if my unites are straight cool / heat or a heat pump.


if you look inside the condenser unit outside,see if you see the big reversing valve,if not it is a straight cool,heat, the heat strip ins in the air handler so you would have to take the side panel off and look for the heat stripe,my the way heat pumps also have a aux.heat stripe just in case it does not get cold enough outside,hope this helps you-mike
