Variable Speed Heat Pump Install

[@themacfan]

Well that's not general electric heat pump. This is a rebranded Mitsubishi Heavy Industry actually 😅 Very respectful brand and good quality ❤

[@mitchmacleod7575]

These units have a variable speed compressor but are constant capacity. Dip switch settings allow for different compressor rpm ramping patterns

Looks like GREE

Because it is!

Where you get your work pants from?

[@USA-GreedyMenOfNoIntegrity]

Gree product - makes them under a lot of different names I see. I sell Airtemp. I haven’t sold any of those 20 sears yet but looking forward to trying them. Have you had any problems with them so far?

[@xcmskim4]

Its actually Haier since they own GE.

[@christopherreus7799]

Made by gree flex or mr cool universal or ge lol iv had mine 4 years now i like it.

[@AaronPowellvox]

GE. Used to be Edison General Electric until J.P. Morgan changed it after Edison failed to get the Niagara Falls hydroelectric contract that Nicola Tesla got. I wonder if they still make a good product like they used to.

Haier bought appliance division of GE can use GE name until 2050 or something like that. So they aren't really GE. Who knows what factory makes them, I had to dig hard to find the info I found.

I like my 4/5 ton but would love the chance to talk with you about a couple of tech questions as my installers were not as well trained. Mine seems to use A LOT of energy in the winter compared to the 5-ton 2-stage it replaced, and I’m trying to see what I can do in commissioning to help. Thanks.

If it's using more power than your pre existing non inverter 2 stage heat pump. You are most likely over sized. I bet the new Connect you had installed should have been a 3 ton. The reason? The inverter type has way more output at lower temps due to the mid vapor Injection compressor. Also check to see if the thermostat they Installed has the second stage emergency heat coming on due to a small differential on the thermostat. Is the d terminal hooked up when it goes on defrost. If so disconnect it. It brings on the back heat strip every time it goes on defrost. That's if you have a electric back up heat strip.

@@John8910 No heat strips, but my setup is complicated by having a zoned system. So the house is probably a 4-5 ton house, but each zone is something less. I'm running 4-ton economy at 4-ton fan speeds (325-350 cfm/ton) to try to get the most efficiency. It has put out 105 deg F hot air under all conditions but at the cost of 7800W of power when it ramps up.

[@John8910]

Well that sounds like a air flow issue. You need to flow 1600 CFM at .5 static pressure for the duct package. If all zones are not calling you will have considerably higher static. I am surprised the unit has not tripped E4 high discharge on the outdoor condenser yet.​@@mooch91

[@John8910]

Are you in a cold part of the country.? Does it get below 20f in the winter season?

[@mooch91]

@@John8910 Yes in Pennsylvania. I can get 1600 cfm at reasonable static, but I targeted a little lower based on Gree recommendation to target the lower flow rates to get the benefit of the inverter and better dehumidification. 1600 cfm still ramps the power way up, just turns on and off more often.

Guys installed different brands of these cute system been having to many problems this new technology 👎 stick with just the basic split system I don’t know how you guys sell these to customers not a money saver no different all you selling is headache for techs when they need troubleshooting
