I see a lot of AC systems set up like this is it the same for a downflow setup for me I'm in a manufactured home my indoor coil is up top blower fan is on the bottom on top of a 20kwh heat strip I assume that the coil can be placed either on top or bottom depending on how it distributes air?
What makes the mini split more efficient then this heat pump? I'm in N. CA around San Jose looking at getting one of these to replace my old HVAC system. Will this unit be economical for this area for both heat and AC?
At first, I couldn't learn anything from your videos. I stayed patient; I did some hands on and read some more about AC. Now I find all your Videos to be the best out there and I learned so much more by watching them. Thank you for uploading.
Changed out a heat pump ac with a regular ac 24 v to thermostat not giving connection I fucked up
You are indeed a very good instructor! Thank You. I’m just getting back into the trade after 30 some years after my initial training. I don’t why and never have know why they would install heat pumps in the northeast! But that’s me. My question is; in defrost mode, isn’t the “indoor” coil blowing cold refrigerated air over the auxiliary heat? Thank You again for all of your videos. Jim
I just replace my thermostat, now my fan will not turn off, even when I shut off thermostat fan is still running. Pulled the Fuses from Wall and it shut off, Woke up this morning plug the fuses back in the wall, the fan came back on, turned on the thermostat to cool now the fan won’t kick on, we’re in triple digits please help
Great information. Thanks for the knowledge.
Thank you for your videos! You've got the talent on teaching. I learn a lot very time I watch your classes! Thank you !
Watched this whole video and immediately decided to buy your book on Amazon to support, good stuff. I wish I had seen this a year ago
So what if the unit in the heat mode has a pressure of 500 plus then locks out but runs ok in the AC mode?
Does this means that the TXV is bad on the HP?
Great explanations and I really love the way you laid the indoor handler and outdoor unit side-by-side. This is so much clearer to me now. I also like the way you explain the defrost process. I'd love it if one day you could expose the inside of outdoor unit and walk us through the sequence of operation along with the indoor air handler. Thank you again!
Does a Goodman heat pump when in defrost mode, should the blower in the air handler be on?
Hello I'm working on a Lennox split system. For some reason I'm always getting low voltage to my O terminal when I'm calling for heat. Ac come on. Why?
Just started my first job in HVAC as a service tech apprentice just a week ago and we've serviced quite a few heat pumps. So I have to say this video along with the other videos I've been watching on your channel have helped fill in the gaps where I was completely lost while in the field 😅 I have taken a semester of classes but thats nothing compared to what you actually need to know when out on a job. But I'm feeling much more confident and can't wait to learn more
