so even if the heat is set at a low temperature like 62 the compressors should come on?
If it is not on does that mean that only the heating unit is providing the heat?
right now the thermostat is set at 60 and the temp indicator says 60. so they match up. As we increase it the temps still align. I think the cold air coming out of the vents makes us think it isn't working. But maybe 60 degrees should feel cold?
Fan is on auto. but the blower runs continually. air does not stop coming out of the vents once temps match. What should the other switch be on? currently we have it on heat.
thermostat is up 6 degrees. the pumps are not running, but the air is a little warmer.
yes they are.
No compressor on.
What specifically should we say to the repairman to explain the problem?
ok. thanks. Can you explain how exactly the heat strips work? Are they more like a standard furnace? ... also, you should be aware that this website appears to be getting hung up - this is my fifth attempt to post this question
I am having issues also with the website hanging up.
In your heat pump system, the heat strips are primarily for backup heat, but when heat pump doesn't work, they take over and operate as a straight electric furnace would.
The elements are energized and heat up, then blower just blows air across them to heat the air.
It costs about 3 times as much to heat the air using the heat strips as it does using the heat pump compressor.
ok - so, if our system was working properly, would the heat strips still kick on for a little while when we crank up the thermostat, until the heat pump gets going? ... or would they turn on only when we turn on the "emergency heat"?
If setpoint is more than 4 degrees above room temp, then the heat strips and pump work together for what is called "fast heat" the as soon as thermostat is within 4 degrees of what you are asking for , the strips cut out and stay out unless unit goes into what is called a defrost mode.At that time they come back on and keep you warm until defrost is complete. The heat pump takes back over.
Then if you turn thermostat to Emergency heat, the pump doesn't come on at all, just the heat strips
Got it. Thanks so much for your detailed explanations. Since all we've ever had before is a standard furnace, it has been extremely helpful to learn how the heat pump and heat strips work. Much appreciated.
