Re: Heat Pump temperature drop
If one is just taking temps at the supply and return vents I have found that new heat pumps do have less of a differential than an AC condenser will. Again there is way to much going on to rely on that. I take temps at those supply and return vents primarily to find if it is the same throughout the home. Whn I do this a heat pump is generally around 11 to 13 degree diff. An AC condenser system is anywhere from 15 to 20. This also depends on the age and seer rating of each unit. The fluctuation from home to home on decent working and maintained systems is in part from the seer of the units along with age and wear and tear of the units as well as outside temp, wind, humidity. Some homes it is 15 and the next home with a newer sytem might be up at 20. It really does mean nothing in the efficiency of any system. You simply cannot judge any real findings on taking temps at the return and supply other than...yup, it appears to be working and the temps are consistent around the home. Now if you find wide swings of 5 degrees and up then you know you have a problem with supply
