It was part of our ducting permitting as well when it was first adopted in the energy code. Then our city just said, “hey, just sign an affidavit saying you did it right”. I was thinking what? ...
They originally quoted me at $575, but it ended up being invoiced $465 I think. They replace the battery, upgraded some sensors, resistors and converted it to WiFi capable. This also included...
Holy 5h^t that sounded like a scary movie! I’ve never heard a condenser do that.
So, let me ask, is this noise recorded at the outdoor unit? Or inside your home?
If it’s inside your home then it...
Same experience here. I don't know how they're doing it, but FP has excellent range compared to other brands, and batteries last a long time.
The FP SC680 is my everyday meter now, back up is the older Fluke 902. There's just way more functionality to the SC680, and it integrates to my smart probes very easily. I still have a Testo 770-3...
Yep, a thermal imager is much easier to use than looking for smoke. Whether it's lack of insulation or leakage, both still need to be repaired. Though leakage typically looks a bit different in a...
How often do you find it's required to smoke test a residential duct system?
More often than not, the majority of leakage is on the equipment/trunk connections, trunk/branch line collars, and at the...
I had the older non-BT Fluke 902 for a long time. It's durable, but doesn't have fine enough resolution for fractional hp motors on the amp clamp (maybe the new FC model does?), and it really isn't...
Like kdean1 said, repeatability is what you want to see with a capture hood device. It takes practice to learn the inconsistencies each have. I will tell you, most flow hoods are marginal at best...
Is the Amana a modulating / variable speed unit? If so, why is the low scfm rated at 1000, whereas the AmStd is 500. The AmStd is 70 stage from 30-100% capacity in 1% increments, I believe. It...
I have a helper that I’m training, and another that works whenever he’s available. I was trying to get into energy auditing to supplement income and do something different, but you hit the nail on...
I hear you, it’s been slow going with the Building Energy Auditing. I just get too damn busy with hvac during the summer to even think about blower door testing. Now that I finally have had a...
I just sent in my Retrotec DM32 for it's 5 year calibration. The cost of shipping a tiny light weight box was $81 from the UPS store or $45 from FedEx drop off location. Retrotec is ~3000 miles...
Just picked up the Edge 2.0, seems pretty nice, only used it once so far. Hope it holds up to van and helper abuse.
Your description in post #1 is not how a conventional system works. I would suggest having a professional take care of your equipment before you hurt someone or yourself.
Oh, the other thing I like about the new Navien, it comes with an outdoor sensor for an outdoor reset. This allows it to condense more often by lowering the water temperature when the demand is less.
Okay, well that makes sense.
In your case I would evaluate your ROI, considering cost of repairs, and equipment replacement. Also look at the features and benefits of the mod-cons. Do they...
CI is obviously tried, true, and going to last longer, but no doubt less efficient.
As for mod-con boilers, I would just go with a combi unit and forget the tank. That’s personal preference I...
Pretty simple, perform load calcs of each room to find required cfm. Test for proper cfm.
If the cfm is incorrect then fix the ducting.
If the cfm is correct, then look at the structure.
The XL950 was retired shortly after the XV units came out. You got one of the first gen inverter drive units. Like anything, there will be bugs to fix. FWIW, I’ve only experienced thermostat and...
Why are you using an XL950 on a variable speed system? I believe Trane has dropped support for this stat a while ago.
I would venture to say those leaks are 99.9% likely to be poor installation. Just watch some of these plumber videos on YouTube, most of them don’t ever bother prepping the piping before shoving a...
You do know they need to be cleaned periodically right?
Some brands like Trane have max and min rpm limits which can be set via the thermostat. This will basically will limit capacity and noise levels. Others like Bosch, will limit capacity...
Just wondering how a Press tool thread became a DIY project q and a thread?
Well, so far they last longer than mfg. made evaporator coils. So, in the disposable age of today, my bets are on press fittings lasting longer than equipment. To answer your question, no.
Yes, the trailing edge kinda gets jacked up because the sheet I’m using for the test isn’t very long and it moves on the last inch or so on the exit.
Also, I find that the support table is about...
Typically 26ga. I did adjust the hold down bolts to accommodate thinner metal, and that seems to have helped a bit. The last pieces shown are after the adjustment. I'm sure you're right as I...
Ok, made a few adjustments and made the corner pre-cuts.
Here’s the lead edge and trailing edge.863823
Well, as it turns out, the power isn’t an issue, it doesn’t even dim the lights when it turns on. It sounds nice and smooth, so I’m not going to mess with the motor.
As for the Pittsburgh seam,...
A question Jim Davis posed in his class; “Are you confident enough with your combustion testing abilities, that you want to leave evidence of your combustion test with your name on it?”
Yeah, I looked up some specs on the motor model: YL90L-4, and it seems to be rated for 220v, but the placard says 110v.
18.6A is likely the SF amps not FLA. Other similar motors have a dual rating...
Have not even turned it on yet, I’m going through it first, trying to get an understanding of the adjustments. The drive belts are extremely tight, and there wasn’t much grease on many of the gear...
Received today. It has cover panels for the sides, but I took them off to mount the wheels, and check out the motor specs.
I was hoping it was labeled for dual voltage, but it’s only showing...
LOL, yeah, that’s typically how it goes, the wife says, “you’re like a dog with a bone”.
It does Pittsburgh, straight flange L, radial flange L, drive cleats with auto trimmer, double hem Z, and...
So, I’ve done a lot of research on options available, and I’m just not sure I’m only going to need the Pittsburgh side of the machine. I found a company in PA that resells a Chinese mfg. using 60hz...
I believe they do make driers made for press, but they would require a coupling on each end.
I’m sitting here debating whether to purchase the iron IPS fittings. I run gas lines but not very often....
I use my Milwaukee M12 for a few years now. Rarely use the RLS jaws, but they're nice to have when working in a tough spot. Can be a real time saver if you remove a coil for heavy duty cleaning. ...
LOL, Ridgid Power Threader was a great purchase, but I too am eyeing the Mega Press for the M12 Milwaukee. End of year, tool time, need to get some write offs.
Just call your service company, and they can walk you through the steps over the phone. Making a wrong adjustment could potentially cause your system to malfunction. While it’s relatively easy, we...
No, the domestic water “desuperheater” coil in the geothermal is required to be atmospherically vented. This means, if there were a leak between the coils, you would have water leaking out of the...
Yeah, it looks like everyone in my local area wants a premium for them. Old rusted out POS for $2500-$4500. If I want a good deal I will have to travel 8-10 hour round trip. That ain’t gonna...
Anyone heard of Harsle Manufacturing?
They quoted me a 7 function machine SA-15HB for about $1750. The catch is, this is a Chinese company which would require overseas shipping.
It claims to do...
Just got a new finger brake for ~$1650, now I’m debating to go ahead with a Pittsburgh machine for $3500.
I feel like bending a flange fitting manually is the most time consuming part of making my...
Agreed, but on my personal equipment, I need an excuse to explain to my wife why I had to buy a new variable speed unit…::DD:
The charge is weighed in. So, there is no problem with charging the equipment. Worst case they misjudge the line length and are a couple oz off.
💯
No glide, no fractionation, higher LFL & UFL, better capacity (for R32)… I don’t understand why we would want 454b over 32.
I guess the research claims there is better compressor reliability, and...
Ok, the leak was found, the leak needs to be repaired, find someone to braze the leak, and replace the filter drier. Forget replacing the switch, it’s fine. Hell my 2-stage XL16i’s high pressure...
This is not a DIY site. I don’t think you’re gonna find the answers you’re looking for here. Please refer to your contractor for advice on repairing equipment.
That said, it would seem to be a...
