CVHM apparently has ceramic bearings in it so from what I can tell its not going to have the problems the CVHE/CVHF units with R-514 are having.

Hopefully that machine has the hardened shaft in it. From what I understand the new refrigerant and the oil don't get along. The hardened shaft will take the abuse better than the standard shaft.

Went from 15.3 MPG to 6 with all that stuff:whistle:

We installed 4 velocity phantom combi boilers last fall. Personally I wouldn't put all my eggs in one basket. When the boiler quits for whatever reason then you have no domestic hot water. This...

The story I got with this unit was one of the guys that works with me installed it years ago when he worked for a different company. It was installed so the AH was in the middle of the...

"well, we can't afford a crane to set the unit on the roof out of harms way, so right behind this parking block will be the next best place"

I have come across that twice in 10 years where some hack installed the drier in the place of the muffler. Went out of the way to make the 1/2" copper fit the 3/8" drier connections. It took...

I run some rx-11 through mine and chase it with nitrogen.

Not sure what is cost to Hydro test the tanks, but i'd say a local Dive shop with hydro capabilities could do it.

Robertson head was a Canadian thing and If I remember correctly he didn't want to license his head or something to that effect and thats why its not as common as Philips. I personally use the Malco...

Finally, a white Christmas in my area! Merry Christmas

Not that I would use this app, but I wonder if it could be fooled if a cell phone had a VPN on it?

The outdoor unit coils?

The aluminum coils are a big improvement over the copper ones for sure. I have had 2 or 3 dud aluminum coils. The Rheem factory guy told me a several years ago they had the furnaces too hot during...

I am not surprised about a Rheem coil shortage! They are too busy handing them out for warranty replacement!

NATE is a joke. They were too tight to even send me a certificate with my name on it. I took and passed the core and heat pump test years ago. One stupid question that stood out to me was the...

You mean not everyone has a plasma table to do complicated duct work with? LOL. My Hat is off to you. It would have taken me a week to make that piece.

Charging with vapor is to protect a reciprocating compressor- to keep from slugging the pistons and valves. Scrolls don't care and can eat liquid while charging.

Just picture your standard Field Controls draft regulator that comes with any oil appliance and drop in right on the breech. I wish i got a better picture. The boiler is on its way to hell now so i...

You are looking down on top of an oil boiler. The Moron who installed this unit clearly is beyond stupid to install the draft regulator on top of the breech! You can see the regulator...

I thought all condensate drains had to have an air gap...

And I thought the H-10 was expensive! Wow. That D-Tek Stratus better be able to sniff a leak from the neighbor's house for that kind of cash :-)

What gets me is the Virginia Uniform Mechanical Code does not mention what is the proper pipe material or fittings to use when installing a boiler. The IOM book for this boiler also did not spell...

Capacitors are cheap. Why wouldn't you just have two of each of the most popular caps (so you don't run out that day) or get a turbo200?

Here is the one with shark bite fittings. The site manager wants me to write up something as to why all of this is wrong so the installing hack will be made accountable for this and fix it...

This boiler only had the compression rings and no O2 barrier pipe.

Found this beauty at a public housing complex. The pex is rated for 180 degrees but not for boiler use. There was another boiler installed similar to this one, and they used...

I can say for sure that they Hybrid water heaters work and are worth it! As for a hybrid dyer, I have my doubts. 40 minutes to dry just 2 pounds of clothes? I can dry 10 pounds or better of wet...

Probably built by the same people that built the University of Florida bridge that collapsed.

The I love the Pro5000 series because of the large display and the easy on the eyes green back light. We have been using the Aprilaire 8448 thermostats and they just seem cheaper than the Honeywells....

Glad to see Honeywell got their head out of their butt and brought back a robust, reliable thermostat! Probably old news to some of you guys, but I just stumbled upon this earlier this week. Long...

The problem with that is you don't know if you damaged any of the ICs on the board. It may or may not properly detect flame or the safeties may not work right. I'd just eat the board and chalk it...

You could have Refrigerant boiling out of the oil causing the pressure to rise.

Looks like bristol is getting a new home in Thailand.

Rheem is the one who leaves the txv bulb loose to be mounted on the suction line later.

I replaced a White-Rodgers type 668-454 primary the other day because the thermostat had now power to it. One of the other guys that works with me claims this unit will not output 24v if it trips on...

There you have it folks, straight from the horses mouth why Goodman systems are victims of Hackery :-)

Where are your low loss hoses? You are going to over use your De minimis privileges

Had a brand new Rheem 16 SEER 4 ton rectangle I installed several years ago do funny stuff a day or two later after i put it in. Kept kicking on High head. Pulled some out and it kept kicking. ...

Looks like the pre made end of the line set. The factory does a horrible job of flaring the ends of the copper.

We hired a roll back to pick up our used 8 ft brake. He dragged it on the deck with his winch and gravity and his winch slid it off onto the shop floor. It took 4 of us to push it to the final...

I will second the rule of don't go up on fan capacitors. I was servicing a heat pump unit and took the cap off to check it with the meter and hooked it back up wrong. Put the fan on the 35 and the...

We use the Aprilaire 8448 thermostats when people want a simple, modern thermostat.

We tore this beauty out this week to replace it with a modern 14 SEER system. This lady paid one of the local guys around 2K to fix this 1991 POS. She got a new compressor, fan motor and 407C...

Yep, You keep going! Its a pain the the butt, but the carbide will eat thru it eventually. We hit rebar in a thick wall one time while drilling a 2.5" hole for a mini split line set. We use a big...

I can tell you for a fact that no parts were forgotten. I toured the Rheem factory in Fort Smith in April, where that baby was born, and they run test every single unit there.

I do the same thing when the wife and I go out somewhere.
