Is it normaal to have the discharged air temperature 105 degree
I recently have my 8 years' old Carrier heat pump repaired by replacing a leaking evaporation coil.
I tried its heating function several times in the morning when indoor temperature was around 73 or 74 degree. I just set the heating temp one degree higher than indoor temperature.
I was a little surprised when I measured the discharged air from the vent closes to the unit. The temperature was 105 degrees. At the same time there was a smell like something burned (I do not know how to describe it exactly, anyway the air smelled different when the heating was on).
I wondered if the electric heater was on since the discharged air temperature was so high. I then used the same thermometer measured the temp of the pipe that connects the outdoor unit to the indoor unit and the reading was about the same. Consequently, I guess the electric heater indoors was not on when my heat pump was running.
BTW, I used a mercury thermometer to measure the temperature. This one is quite accuracte since I compared its measurements with another digital thermometer the number
was very close.
I wonder if my heat pump functions well. Many thanks for your help!
