Mr.Cool 2-3 Ton Install, On Existing Furnace 

Dual fuel if you use it yes. Most t stats with a reversing valve terminal are so I didn't even think to mention it. I use a sense thermostat. Works good

No. But they do make a unit that's 700 bucks cheaper if you don't need the heat pump function

@@scottlanier5133 condenser varies it's compressor speed and fan based on load and outdoor Temp. Indoor fan runs at 900cfm fixed regardless

I should also had my indoor coil has a txv. With a piston it might not regulate as well on the outdoor unit? Not sure

What did you do to get it to do this? Mine is running full speed on outside and then cuts off. I am using an ecobee lite thermostat but it doesn't seem to be ramping down​@@Bobdudeman1988

​@@Bobdudeman1988mine has a txv as it had an older heat pump

@@scottlanier5133 sounds like something might be wrong. It should do it out of the box. I hate to ask but I don't know your skill set.dont take it personally ..Did you evacuate to sub 400 microns? Service valves all the way open? Did you add any refrigerant if you have over 20 or 25 feet of line set? There any codes on the control board? There is a free flexx service manual out on the web that can help you troubleshoot

My indoor coil is only about 4 ft lower than my condenser. I can't recall exactly but the gree manual said if it's less than x number you don't need it.. I wish I remembered what it was. I didn't do it and it's been running fine. About 15 months so far

I assumed it was cost. But maybe your right. So far it's been working well

So far. It's been great. It has not been that cold yet here though. 19f at night was the closest and it had Zero issues. Iirc it was pulling 10 amps and ran for about 9 hours out of 24 hours. 1600 sqft house

@@Bobdudeman1988 WOW that's like the power usage of two space heaters. Very impressive.

Doesn't hurt my feelings, comparable domestic condensers run 10k for the same performance. Least right now. If it blows I'll simply repair or replace. The roi on it is short as well

With my specific install the Mr cool unit was too tall. And I have no more head room to raise the duct. This way it was a direct swap

Depends on the coil. R22 vs 410a. Also depends on the expansion device. If it's a txv it needs to support reverse flow, some have check valves that wouldn't allow it to work in heat mode. If your coil has a piston you would need to convert to a bi flow txv

Been mild as far as winters go, we did have one nasty cold snap, but overall, it has been flawless. during the cold snap it was more costly to run compared to gas however those costs could be made up by installing solar, like i plan too. As far as a cutoff, i have it programed as straight heat pump, no backup. i haven't needed any form of other heat, this unit has provided it all, all winter... ill be converting the furnace to run on propane and storing 100lbs tank to use as backup if never needed. See my video during the cold snap ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-39q6hQnDJqg.html

@@Bobdudeman1988why would you convert to propane when it’s more expensive to run than natural gas? Are your rates that much higher in Wisconsin?

@@NovvaOfficial because i haven't used any gas since, and W.E. charges 14 bucks a month just to have the gas line connected even if i dont use it. the propane is just incase my system cant keep up for a a while(haven't had that issue) or it fails and ineed backup heat. most heat pumps have electric backup heat but mine is not set up that way.

@@Bobdudeman1988 Understood. I work for a gas utility and your $14 is the rental fee for the meter most likely. I enjoyed the video. It’s pretty eye opening for people who want to do this and have the capabilities to perform the necessary work to actually get it up and running.

its been over a year with mine and its been great, They are made in China by Gree, who is probably the largest ac producer worldwide iirc, failures happen, im sorry yours has not worked well. not many domestic techs work on these kind of units.

@@Bobdudeman1988 my tech actually laughed when he saw the name brand . I was like yeah I know LoL. I bought a carrier cause I didn't want any more problems. I live in south Florida and I have to have my ac cooling

@@CubanMofo nothing wrong with carrier units. I like there rtu,s. Wisconsin can be just as nasty humid in the summer as Florida believe it or not. I'd die without ac too lol

Works well. The coil on the inside has a txv on it. I'm betting the unit outside monitors superheat to control it in the summer. During winter the txv is not used on the coil and there are 2 exv inside the condenser. Not versed on how they work

@Bobdudeman1988 Sorry, I didn't word my question very good. How does the variable capacity condenser mesh with a single or 2 stage air handle? I'm just trying to figure out how it works.

@@rickye7738 it simply calls for single stage heat or cool. And the condenser literally " figures it out" it's actually pretty impressive

@Bobdudeman1988 That's cool but I'm guessing that if the air handler is operating at full capacity then the condenser is never going be able to reduce capacity enough to increase efficiency or decrease unit short cycling or improve condensation removal. I'm I missing something or is it kind of a waste to have an inverter compressor run an almost full capacity all the time?

@@rickye7738 it for sure isn't a waste, it does what It can to maintain a constant suction temperature I'm assuming, but it varies how hard it's ruining based on outside temps and refrigerant load returning from the coil. It does a very good job pulling humidity out of my home. .

I built it from scrap tubing. my idea was to wall mount it like a minisplit but at 250 pounds it was too heavy for commercial offerings I was able to find as well as its width was too large. so I made the sand instead, its holding up well.

You'll need to be more specific..

@@Bobdudeman1988 The low voltage to the indoor furnace and thermostat from the condenser

@@harmonairllc2368 it has the thermals for the basic wires y,w,g and b inside the condenser I don't use any heat strips and I didn't want my furnace trying to use gas during defrost. So I left w disconnected. It hasn't been super cold yet so I may change it but so far it's been good

During defrost it calls for fan or emergency heat ( in my case normal gas heat) during defrost to prevent a chill during it. But it only last like 3 minutes

@@Bobdudeman1988 So the condenser is just missing the component to shunt the 24v and switch the cycle to cooling while in auxiliary for gas heat. Defrost timer/temperature senosr
