Home ac having problems - freon doesn't seem to be circulating

e:

Covre the heat pump outside during the winter? Doesn't really heat very well when you do that does it?

[GregS]

One thing you can do is take a clamp ammeter around the 220 line and measure the amps. On mine I measure 6 amps, which probably shows some loss of refridgerent but its still working. older AC will draw a lot more amps.

[Stormin Mormon]

That can provide some information. Of course, an older unit will draw more. A dirty unit will draw more. An under charged unit will draw less.

Dirty and undercharged can cancell each other out.

Great link! Working that back, led to a list of JPEG files, that can be printed.

The OP stated that he was using it for cooling only.

I realize economic hard times require a flare in salesman ship but I have to take issue with a few things. The first one is the scare tactic about price and availability. Price wise r22 costs exactly $1.11 more per pound than r410a. Availability wise, r22 will be produced until 2020 although at a reduced rate as you said. How much the price will actually go up is based on a guess but Im willing to bet as r22 goes up r410a keeps pace.

The second one is the quantity of r22 in a 10 seer system vs r410 in the new minimal seer rating of 13. The 22 system held (arco aire) for instance 4.25# of r22 where as the new unit of the same size (2.5 tons) holds 4.10# of r410a. Not even close to half. The cost differential to fill both systems is less than five dollars.

That being said, sometimes I read some of the stuff here and wonder, is it mere ignorant misrepresentation or borderline dishonesty. I also wonder if sometimes when these sales pitches are given if you can actually see the sales mans nose growing.

Your brain and mouth cancels each other out.

[.p.jm.]

You give him too much credit in the first half of that. Unless of course his mouth is empty, in which case I understand the comparison.

[The King]

Assuming he has a brain, it dosen't work very well.

[The King]

opps. corrected.

[Steve]

Too bad you couldn't cut it in the resi market, and had to resort to doing commerical/industrial in a union shop.

For now, the price of R22 has not yet started going up.... but its coming, you know its coming. Think back to the R12 phase-out. This is the same scenerio, but on a much larger scale.

[Don Ocean]

The latest word I have on R22 is that this year only 20% of what we normally use will be available. The large producing companies are indicating that the price will skyrocket and that it would be a good idea to purchase large quantities in advance. I suspect the companies are trying to create a shortage to drive prices up. Also it turns out that R134A is being scheduled for a phaseout in the future also. R410 and a few others are also to be replaced. It was stated that Carrier already has a replacement in their research facility. The socalled replacements will consist of HFO's and CO2. This information is merely being repeated and the source is a Johnstone Supply Training person.

Welcome to the future of the cooling industry, after Brobama gets done 'reinventing America' for us.

On the bright side, at least it's a 'green' job .....

[Don Ocean]

You could be partially correct. I have met a large number of Commercial HVAC techs that have switched to the light inductrial and residential markets. I also note some new licensing requirements coming in the upper states. They are going to redo licensing to :

(1)Masters Cannot touch any work, but has to be in direct contact with journeyman at all times on the job..Cell phone is acceptable. Cannot bid jobs, but is under a contractor.

(2)Journeyman Can do work and direct Apprentices and helpers.

(3)Apprentice must work under Journeyman

(4)helper Can only do menial chores, Wash van, Sweep floors and not allowed to touch contract work.

There are also 4 vocation licenses. #1 would be a plumber under its own subgroup. #2 would be HVAC at one of the above levels. #2 would be Hydronics at one of the above levels #3 would be refrigeration at one of the above levels.

Which means in certain cases you would have a large number of licenses. It does appear to try and kill off the one man operations. The Unions under the Obama administration have been the drafters of this muck.

However...HVAC licenses will place up to 40 gallon water heaters for install and repair in our bailiwick. Any water heater above 40 gallons will require a Plumbers license.

Last but not least the Feds seem to be involved in eliminating the EPA licenses all the way up to Universal. For the replace system there will be a $280 filing fee and a $300 a year renewal and possibly more. If anyone has better data on any of this please post it.

What might increase it more is the fact that the 3 substitutes may be pulled from the market due to some international treaty that either has been signed or is waiting to be signed.

Resi is so easy even Stormy muddles his way through it. But hey if you find it challenging thats cool too. Yeah I know im just a lowly commercial/industrial union tech. Not quite as prestigious as a residential service mechanic but it pays the bills.

Its hasnt gone up? Okey dokie. Sorry Steve I wasnt trying to ruffle your feathers but your nose is growing.

All refrigerants have gone up and you know it. Still its no reason to use scare tactics to convince a customer to buy a new system for

5-15G's or what ever you charge when they have a bad compressor or something. Im all for energy efficiency and the like but sell it as such and if your real honest about it you would point out the pros and the cons of the newer equipment and let the customer decide whats best for his wallet. Thats how I operate

Even if 22 went up to a grand a 30 at that point you just use one of the drop in's for 22 at a much cheaper price. Like we did and still do with older r12 systems. We dont sell a new walk in or reach in because the old r12 system has a leak. We fix the leak and convert it to 414b or what ever you flavor of choice is. We will do the same thing down the road with 22 systems. I can just see it. you walk up to a million dollar chiller and you tell the customer OMG its got a leak, you need a new chiller. Yeah thats gonna fly. Not.

One more thing about this manual J stuff. I bet you a hundred bucks that you could have five manual J's done by five different companies and have five different results and every one of them would say they are right and the others are wrong. The old garbage in garbage out thingie. I mean really, theres like a 10% fudge factor built in to the damn thing so it isnt an exacting science now is it.

[.p.jm.]

You wanna talk 'difficult' ? I talked to a place today that makes custom one-off equipment that does things like :

Maintains high flow volume ( 500 GPM + ) process water at 0.5 C. Can you say 'on the hairy verge of becoming slush' ?

Maintains other process high volume chilled flow water within

0.2 F precision of setpoint. Does it LARGE ( is making a hundred tons of ice a day 'large' ? ), and in HOSTILE environments ( this ain't no little pansy-assed lab equipment living in a carefully controlled environment, this shit gets beat up by illegals all day every day ).

Does it all while maintaining FDA-level 'food grade clean' EVERYTHING.

I was impressed.

[The King]

134 was always going to be an interim refrigerant long before Obama came along because its a greenhouse gas. The Europeans are phasing out its use in autos beginning next year and banning it all together by 2017. Its old news. They wont be happy til were back to using ice.

[TimR]

As far as I know, there is no consumption of refrigerant in any residential system.

If you're low, you have a leak. You fix the leak and refill. There is no periodic topping off of refrigerant that got used up, can't happen.

[The Daring Dufas]

I recover every ounce of refrigerant I can. If it's not contaminated, I'm going to reuse it. Somewhere I have a 124 lb R22 recovery cylinder. I take a little whiff and if it doesn't burn the hair out of my nose, a good set of filters and some Acid Away makes it usable.
