Great video! I think you'll be pleased with the performance of the heat pump. I installed my 3-ton unit this past spring and I love it! I kept my old furnace and just replaced the A-coil with a Mr. Cool Universal connect. I added a Google Nest Thermostat and set it to dual-fuel mode so the gas is only used at 20F or lower. I'll probably drop that lower it's been working so well this winter so far. My only tip so far would be to consider the drainage on the outside unit. It can generate a lot of water in the wintertime for the outside compressor, due to the defrost cycle. I'm n the mid states (KY) so I don't need to worry about uber cold, but in the -20F kind of temps, I could see the unit getting frozen defrost discharges coming out of the unit. That said, for I've been very impressed with the combo of the Google Nest thermostat and the Mr. Cool 3ton Universal and their A-Coik DIY config. Not one, but Two thumbs up from a user.
I've been super happy too. Dropped heating energy usage by half. It seems to be a little louder in heat mode and the lineset seems to vibrate more so than cooling mode. But saving 5k sure makes up for it. Still happy with it.
I am not sure where you're located, but I am just curious if you get bad winters occassionally? I am happy to move to a heat pump, but we get pretty harsh winters every few years and I am not comfortable eliminating the gas furnace yet. I am more than happy to eliminate my natural gas service, though. There are regulators that can be used to switch to propane, which I will likely do if I find that my gas usage becomes non-existent in moderate to mild winters... but for those winters where we get 2-3 weeks of -15F temperature... I think I will either need some alternative or a heat strip. I am also leaving the possibility open for a different alternative. Propane would be nice because it is readily available and I can get a tank sized as needed... it would also work to allow me to continue to use my gas fireplace, which I would suspect to get more use than the gas furnace once the heat pump is in. However, I wouldn't be opposed to some biomass furnace, either... wood pellets or corn cobs. I like the idea of the corn cobs. I don't grow any corn (and if I did, it wouldn't be much because I am only on 2/3 of an acre), but some satisfaction exists knowing I could grow some corn (and use to make some libations) and use the cob for winter heat. That would leave me with the gas fireplace... I wouldn't be able to remove it and I would want it to be functional, but I don't think it is suited for much of an alternative.
We see below zero temps, see my other heat pump videos. I wanted to be off gas altogether. It's been nice so far. It takes a little longer to warm up for gas, but I already seen a 20% efficiency increase from my gas furnace since it was only 80% efficient.
@@stem_saving1644 I definitely want to be able to call up the gas company and disconnect my service. My minimum bill for maintaining service with zero usage would be $40/mo... so just having even the same consumption costs if it were 1:1 from gas to electric would yeild a decent savings. I think I have a lot of the same things planned that you've been working towards. I am slightly hoping for a harsh winter this year to put the system to the test and gain some confidence in it. I am wanting to get a heat pump water heater and to get an induction range. That would only leave the furnance and fireplace, so if I can be confident in having consumption of those being low... I can bare minimum swap regulators on those to propane and shut off the gas service. I am kicking myself a bit, though, because I had years of repairing my appliances and last year we replaced almost all of them except for the oven and range. Even though I was eyeing them, I got a stacked unit rather than a heat pump drying system. I really wanted to get two of the combo units that are washer/dryer in one single unit. It would really help support moving towards solar just because it would be more efficient and lower any spot peak load on the system.
When the old condenser still has power run it and close off the valve on the larger line the suction side will draw all the freon from the lines after a few minutes, then close the suction valve and all is trapped inside.
Thanks!

Was rhere a part 2 i missed?
It's in my Playlist
did you evacuate the refrigerant? if so how?
Not yet, still working that out.
When the old condenser still has power run it and close off the valve on the larger line the suction side will draw all the freon from the lines after a few minutes, then close the suction valve and all is trapped inside.
You mean the smaller line closed (liquid) and leave larger open. The issue is still getting rid of compressor full of freon.
Can you keep your furnace as a backup
Not the way I designed it. There are dual fuel ones, but I wanted to be off gas altogether so I'm free of all the junk connection fees.
