Had a new electric heating system installed not so long ago (basement unit plus outside heat pump). The basement unit says Payne model FB4CNF024. I've suspected there wasn't a filter in it based on the dust in the house, and sure enough, the installer came back and found there wasn't!
He told me it takes a 14 x 24 x 1 filter and it would hang out the slot. I bought one, but a 14" filter is too wide! I cut the one side down as a temporary measure, but it does stick out 3" past the opening, and it still doesn't fit right. It does not seem energy efficient to have the front plate off and the filter sticking out the front. Air blows out from the slot, and I can't imagine they come with a front panel if you aren't supposed to have it on!
Does anyone know what filter this furnace takes? I am thinking 13 x 21 or 22 x 1, in order to fit it in width wise, and for it to not stick out the front, enabling you to put the panel back on?

Nothing is wrong with unit ,that's how heat pump work ,you should also have a 2 stage heat which most likely electric heat so when heat pump cannot keep up with temperature the electric heat should kick in and heat up the space
Check your thermostat and heat pump owner's manuals. Thermostat may be programmed to require electric heat at higher temps. Also could be bad outdoor temperature sensor tied to
Heat pump system controls (I had that problem) When was it installed? Warranty thermostat and or Heat pump? Call installer
Thermostat programming is a headache. No help from installer? call customer service heat pump and thermostat. Some possibility of bad installer wiring. There is also a heat pump "defrost" cycle. Usually the Electric coil will turn on to compensate for the Defrost cycle which is just the standard air conditioning mode therefore moves heat from inside to the outside coil to melt the frost. This cycle may be occurring too often. I had that problem. Fixed under warrantee.
Heat pumps are complex machines. The controls even more.
You need a tech, hopfully you are still under warranty.
Hope this helps.
Dan is this a new system, or has some work on the system (to include the thermostat) been done recently?
Sounds like the thermostat may be wired wrong. From what you describe, the igniter element is coming on, as though you are calling for heating. Do you allow the ignitor to keep going and see if the gas fires off, or are you seeing this and shutting down the system immediately?
If you had the t-stat changed recently, or this is a new system, contact the installing contractor. It may be under warranty.
I would start with your outdoor thermostat located in
the unit outside. I`m assuming this is a heat pump.
When the outdoor temthermostat is set to say 40F
anything lower than that and you are not using the
compressor, you are using electric heat thats located
in the air handler unit in the house.
I`m also assuming this is a split system and not a
packaged unit. If you are mechanically inclined and
you can locate the outdoor thermostat lower it below
the outdoor air temp and see if the unit comes on.
Sounds like you might have a problem with your electric heat or emergency heat
Are you referring a to an electric furnace providing the heat, the heat pump providing the heat, a heat pump providing heat usually with an auxillary/emergency electric heating unit, or an air conditioner with an electric furnace attached? If your system normally uses a heat pump for the heat normally, there is an eletric auxilliary heater. You'll probably need to turn it on at the thermostat manually when the outside temp gets below 40 degrees. If you have it nice system, it might do it automatically. If you're referring to the electric heater being rated 8 kw, it'll run using 8kw when you turn it on. It doesn't have the ability to change what heat rating it is. If you're refurring to the heat pump system being rated 8kw, you're probably mistaken. A heat pump might possibly consume 8kw to run the system but that can't be a measure of the system's capacity. Heat pump measurement units are rated in tons, but the system will always run at the same ton capacity whenever it's on, provided it doesn't need any maintenance. Some commercial air conditioning and heating systems have to ability to modify their power output based on the outside temperature, but I doubt you're dealing with that kind of thing.
First when you add new vents make sure your unit is big enough to handle the extra load. If you have shut off your vents to the basement. and it does not cool you may have AC problem. Sounds like you need to get it checked. Ask for a free estimate before you commit anything. Remember if they add gas you have a leak and it should be found. Rus When your ac does not cool properly check filters float switch in unit. Breaker on outside unit. Take a thermometer and take a reading from the reurn to the closest vent you should have between 17 and 21 degrees diference across the coil. If you have electric heat or heat pump you may need have a heat sequencer stuckmkeeping part of the heat on during cool.
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
It sounds like the unit has lost its first stage of Heat (It uses the outside unit to bring heat in with freon) When the thermostat is put 3deg higher than room temp it uses Heat Pump and heat strips, this is probably the only time yours heats. Have it checked as you will pay a lot on next month's electric bill.
