I have applied for the pro membership on Nov. 27th. But I still haven't heard anything from you guys :toetap:



Yeap, 60 psi on low and high, when not runing. 10 psi high and low when...

The unit was frozen up outside and inside two days ago. I couldn't do anything at that point, told them I need to comeback.

I went back there yesterday to find standing pressures to be on a 2 ton...

Hungrytech,

That totally makes sense. Thank you for trying to understand my question and answering it. I was reading up on Geothermal heat pumps and I think they work the same way as the...

2010,

I sent you the email, however the email address that you have on your public profile rejected it. Let me know if you have any other means of getting in touch with ya...later

I will send you the info through email.

I definitely am not a pro. I am a rookie in the field, its my first heating season, and trying to learn as much as possible. Things do sound so easy in the book, but completely different in the...

Hello everyone,

I can't figure out what is going on with this Carrier Gas Furnace. I got a call, customer telling me the furnace was on last night but it will not turn on today. He said pilot was...

Prices for a GEO system in this area (Northern Virginia) are insane, but at the same time it is becoming more and more popular. I still haven't seen a GEO system, I was so close to seeing one the...

Gotcha !
I have once seen a heat pump like that in a condo. But what I was wondering was where the heat pump was releasing heat in the ac mode ? Because the heat pump only had evaporator coils, and...

mayguy, you are absolutely right. It must have been the budget !

If there isn't an open field could you still not do vertical loops on GEO ?

Run Forest Run !

Nice work.

How are these boilers connected and serving to individual condos ? by baseboards or air forced air handler ?

I wonder why they didn't go geothermal...hmmm:munching:

I am no expert, but this does look very impressive.

Trane never stops. :pileon:

As long as they have a smile on their face, I don't care. Its only annoying when they think they know more than you !

hvacmac7, you are right. once the panel is off, the pressures do generally go high. I never take pressures with panels off. I think its the air volume that goes through the coils is not enough and...

Yeah the concept of heat pump is neat, in heat mode outside unit is Evap. Yesssir !

Thanks for the chart Kevin. This absolutely will help me diagnose heat pumps better (with elements off). I just...

I know I am !

Cheers

I thought the temp rise was low and the pressures for low side to be high too, now that I am starting to make some sense of heat pumps I will start to inspect them thoroughly, as I am noticing the...

Okay,

so i ran a service call on a heat pump today, and you bet I stayed there way longer than I should have.

I took off the wire from the tstat and ran the heat pump, my delta t was only 14 !...

Thanks guys !

After doing some reading, I also concluded that the thermostat and wiring has a big role in how the heat pump works. I am goint to try all these methods.

Good afternoon Gentlemen,

I am a junior tech who is struggling to understand temp rise on heat pumps. First and most importantly I would kindly like to know the general procedure to inspect temp...

Steph, during the time your coils were frozen up did you say you did not feel any air coming out of your vents ?

I don't think low level refrigerant level can cause the blower motor to shut off ?...

Skip, thanks for the attachment, its very informative and interesting.

Kx, good luck with shopping the systems.
