Dave I just put this in and 60k furnace 2 stage. Oh is it quiet compared to old Goodman furnace blower. And old Payne ac. That one hasn't blown cold for 9 years we've been here. In theory 30% electric savings for this vs 10 seer old under charged unit. I pray i did the install right. 420psi high pressure test. 270 micron vac hold for 20 min. I was shaking in my boots the whole time. Start to finish part time 9 days.

... and one more thing, here in California, last January (2023) they did a price hike and we paid $600 instead of $150 for the LNG. Conversion to heat pump is a no-brainer here (where there are solar generation options). Similar conversion benefits also apply to even Midwest and the most of the country. Electric rates will go up but fossil based fuels will go even further. So heat pump is a MUST.

@@Ron_Masterjohnnatural gas is piped to your home by the gas company. It is “mined” from gas fields, primarily by “fracking”. LNG is the same gas, but cooled very cold, to change it from gas to liquid. It is the best way to ship gas when gas pipelines are not available. Usually on ships to other countries. It would be too expensive to store and use in a home. I think you mean LPG, which is liquified propane gas. It’s the gas that you buy in small tanks for the gas grill, and that you see near some homes out in the country that don’t have gas pipes. It’s usually delivered by truck to a large tank close to the house.

You are a threat to many HVAC contractors because you educate the public. Here's why. This applies to many trades and not just HVAC. Let's focus on HVAC, though. You're average, but not all, HVAC guy prefers an "uneducated" consumer. Let's say your AC goes out and the problem is a bad capacitor with the top swollen and about to pop. A Titan Pro 45/5 costs 10 bucks retail. Takes 5 minutes to change. The AC guy tells you need a cap, contactor, need to clean to condenser, new condenser fan and a defrost board because you have a heat pump etc and all you have is a simple problem. That will be 900 bucks, but you don't as a consumer know any better so the consumer coughs up the scam money. Keep up the good work educating the public.

Blows cold air. I clean the condenser and I pull the blower because it is filthy and clean it. Slide it back in, connect electrical and turn it on to cool. grandson says I see smoke... it was a very fine mist of refrigerant at the base of the evap coil. Two almost microscopic leaks. I tell her to call "X" who i have not used before, but recommended. He has been in business for decades. Coil needs to be replaced no problem. Old coil comes out, new goes in.

In the beginning, you stated the flue pipe had to be changed to flex pipe. The existing flue is already double wall. An 80% furnace utilizes double wall flue pipe. The only reason you changed it to flex was to make the furnace termination easier. You could have stayed with the double wall flue pipe but possibly would have needed an additional fitting.
@EarlHayward 11 ай бұрын
Moreover, the more efficient a furnace is, the greater the need for double wall… If too much heat is lost, the natural draft could be impaired and you could have carbon dioxide coming out of the draft hood (assuming it is not fan forced)… Speaking of which, there is double wall flex vent pipe - I know Metal Fab has some, I assume the others also have, but it has been a few years (technically decades) since I have done anything with heating equipment…

Most manufactures make systems where one condenser can support 2, 3, 4 or more evaporators (sometimes called a head)… However, unless it is a variable refrigerant flow (also called variable refrigerant volume) all indoor units must operate in the same mode (in other words, all will be cooling or heating)… Regardless, both types will probably save money, but improving insulation and preventing heat loss is probably a better investment!

This system was going from 410a to 410a but if this was a r22 system you can easily flush the lines with these little foam bigs you shove in the line and blow through with nitrogen. But honestly, if there is no acid in the system, I’ve replaced a ton of systems without flushing the lines and have had zero problems. The minimal r22 oil isn’t going to cause any harm.

The unit we went with did not have quick connect linesets which did not bother us, we flared the lineset ends, pressure tested the evacuated and did decay test. The system we installed is a weighed charge so you just add per length of lineset if needed. You can calculate superheat but it does not tell you a lot since the metering is in the unit and it has an accumulator. I guess time will tell if we run into any issues.

Is that mini-split style condenser still a variable refrigerant flow? If so, how does it work with the TXV? Obviously the furnace isn't variable but is there still an efficiency gain from the condenser ramping its compressor and fan up and down based on cooling/heating load? Or is it just going to run wide open?
@diyhvacguy 11 ай бұрын
Yes so the furnace is a single speed very basic fan, so when the ac kicks on it always goes into the same fan speed obviously. However the thermostat tells the compressor which stage to go in for the outdoor unit, so if it’s only calling for a degree of cooling or heating it will go into single stage, and it also uses outdoor temp so if it’s way hot out but only calling for a degree it will probably go into stage 2 but the thermostat controls the staging. The indoor coil is regulated with the multidirectional txv, and the outdoor unit actually has an EEV (electric expansion valve) so they work together and save money. Not as much savings as having a variable speed fan but I wanted to keep my standard efficiency furnace because I love the reliability of them. The main reason for me swapping over is so I can run my cooling OR heating with my generator now even if there is no electricity or city gas. Cheers

Why not let the heat pump and furnace run at the same time? That's how we have ours set up. Granted our aux is heat strips. (Florida, we almost never go to emergency/aux heat).
@EarlHayward 11 ай бұрын
If your furnace is heating at the same time your systems is in heat pump mode, you have problems… Are you sure that is the case? Any competent technician would make the furnace backup heat (triggered if indoor temp drops too low)… One would have to wire a thermostat incorrectly to. Are both operate at the same time as you assert, and (again) that creates issues!

No, the fitting on this one was not a true 3/4 so that wasn’t an option. And the only way that would be possible is if you have a bi directional txv. Most are setup for cooking only but if the coil says for heat pump also then you could totally throw a heat pump condenser on it and be done.

If only they could make these systems accept solar panels without the need of an inverter (like the eg4 mini splits). This is such a ni brainer for sunny places. With 1-2kw solar panels this should barely get any energy from the grid during the day

Solar is only DC, so until there is some new invention with solar technology, you would also need an inverter… Alternatively, I suppose of the entire system could be DC, but then one would need a Rectifier… Six of one, half a dozen of the other!

You can still use your current system.RS-53 (R470A) is going to be the drop-in replacement for R410a systems. The new units after phase out will use R-454B. You can't use R-454B in an R410a system because of efficiency, and R-454B is more flammable. New compressor designed for R-454B.

I thought you were going to do something impressive, actually CONVERTING an ac to a dual fuel heat pump. By adding a reversing valve, accumulator, outside unit txv and defrost board. Along with adding a check valve across both txvs. Instead we get a standard rip out the old and install a vendor’s new heat pump.

Demotion warranted. At the end of the investigation, it was, apparently the information provided that the suspect had allegedly committed an assault was invalidated. The police had identification from her, or they could have identified her appropriately from her husband. Making the decision to arrest was improper. She had a couple of drinks and an argument, and essentially was free to leave after it was found out no crime was commuted. The Sergeant and his "take her to jail "attitude is what leads to lawsuits as well as public distrust in law enforcement. Placing people in jail is not the solution to many issues. I would recommend departmental action to demote....
