We're on propane, which makes it tougher to track cost, but I never noticed a difference with our 24/7 system with dedicated recirc loops running. It did take me a long time to get the valve settings and pump timing right, though. Leaving the pump running all the time caused the temperature in...

One last update. I had it on last night for awhile and, sure enough, the flame got much more orange after a few minutes: I don't understand the physics of that, since it's open to unlimited outside air, but I'm pleased with it. I'll just have to remember not to inhale. Mark

Thanks man. I'll tell my wife the flame color is just a reflection of the glass beads, and her beautiful eyes. Yeah, I've been married a lot... Mark

Thanks for your help guys. I got back to this today and in the process discovered the instructions for the converter kit the plumber left. He left a few other things (out), too: The original propane orifice was still installed. I replaced it with the natural gas one from the kit. The cover for...

Thanks guys! No, just plain ol' natural gas from the city utility company. The new ignitor should arrive today, so I'm wanting to get this thing going this week. I am still wondering if I shouldn't close off some of the inlet screen. Mark

I found the propane connection stuff today, and there *was* a regulator in the hose, but there is not one on the natural gas hose. Also, I found the propane orifice, so I'll be able to compare it the NG one. With respect to the valves, my knowledge of how these work is embarrassingly low. I...

The unit I have is approved for conversion, at least in the sense that Akoya (the manufacturer) sells a conversion kit for it. That kit is what I have, but there isn't much to it: Just a hose, the exact same valve the unit came with, and a new orifice. I was surprised, but there is no regulator...

My wife had a plumber install a firepit last year, and install a propane-->natural gas conversion kit. The valve has gotten corroded and needs to be replaced, but I'm now wondering if the guy converted it correctly. I have two questions: 1) Is the screen air opening in the burner supposed to be...

Mine's 200ft, door to door, with about a 4' rise. It's a beautiful walk on a nice day, but can be brutal on an icy cold windy one. I have to be very careful about critters at night: Mark

I'd never place a slab, or even a sidewalk, without rebar. It's just a terrible place to cheap out. As others have said, the slab will crack. The questions are, will the cracks expand, or not? Will the slab shift so that the lip of the cracks are higher on one side than the other? Without rebar...

It's a good question, and one I considered, albeit briefly. Others have addressed the idea from the perspective of a contractor, and I agree with them. I'll address if from the perspective of a poor slob who just wants his AC to work. :ROFLMAO: From what I can tell, the Genteq motors often...

Final update, maybe. I ordered a fan from HVACDirect and got it installed today. Time will tell, but so far both the heat and cool cycles ran as expected. As nearly as I can tell, the new fan was OEM and identical to the original, and I got it to my door for $860. The local HVAC outfit wanted...

Thanks guys!! I'd seen the $7xx HVACDirect price, but was wary. Perhaps I shouldn't be. Since no one has addressed it, I'm assuming "programming" the speeds in these motors isn't a thing. Mark

They don't ask for serial number, but they do say it "fits" my furnace's model number. So long as it's not been installed, it is returnable. Of course, I'll have no idea if the fan speeds are correct without installing it, and even then only by sound. Overnight, Repair Clinic changed the status...

One more question... (Heard that from me before? :D ) For a given ECM fan SKU, the speeds associated with each wire are fixed, correct? IOW, they are not at all "programmable", so that if you need different speeds, you buy a different SKU, right? The AC fan speed has started failing more, and...

I need to look and see what, if anything, we have. I know we have a generator, but I suspect that's it. I keep our network stuff on a UPS so it stays up in the minute it takes the generator to restore power, but I never thought about protecting the HVAC stuff. :ROFLMAO: Mark

/\ Great post! Thanks!! Our ductwork in this 40+ year old house is what it is, but I can certainly do a better job keeping clean filters in it, and making sure the vents are open. Since I've demonstrated that the blue and yellow wires don't make the fan spin when voltage is applied and the fan...

Thanks guys!! Your answers are what I was expecting, which is reassuring. You are all spot on about residential HVAC outfits. I wouldn't be at all surprised to find that the "techs" have a commission component to their compensation. Certainly that's true of the first outfit we had out. As every...

And another little piece of me dies... The TL;DR is that I'm back where I was on the 17th, though the story may interest some. A couple of days after my last post, the AC fan failed to come on. (It came on later that day, and has failed one other time since.) I figured I'd just order a fan...

Thanks guys, I think... :ROFLMAO: My troubleshooting skills are decent, just from my professional background and hobbies, but knowing nothing about the subject at hand - like even just the rudiments of how furnaces work - tends to mitigate that some. You guys helped a ton with that, and taking...
