What are you doing with this unit? When I repair refrigerant leaks, I use a bullet valve to assist recovery. Back at the shop I would braze a liquid line access port into the location where the...

Regarding R-410A, I was once given a list of formulas for weighing-in additional charge when conditions were not optimal for adding charge by subcooling. The list was confiscated by a former...

One company I worked for was owned by two brothers who inherited the company from their father. They split responsibilities by residential and new construction. I worked in residential, and the one...

I once worked for a company that implemented AirTime 500 principles after I was hired in 2000. The system pays handsome commissions if you sell repairs, accessory products, replacement systems,...

I'll ask my supplier. Never wondered until today when I wrote the post.

My boss does not order Goodman equipment more than twice per year if he can avoid it. We have not had good luck with it, but we just installed one on 6/5 (which turned out to be excessively...

I advise customers to turn it off only if the power goes out to reduce the restart load when power is restored. If they don't, it's no big deal. In the past I've encountered situations where too...

My boss swears by the Nu Calgon E Z Seal, but only as a last resort in case of emergency. He has used it in a few nuisance systems, never had a callback on any after that. He did tell me he...

My current employer provides only diluted acetylene (no oxygen tank and I don't know what it's diluted with) for brazing, and this is my first encounter with it. The torch attaches by reinforced...

Thank you, Jim Bergmann, for the explanation and clarification. I appreciate the time you took to respond.
:CU:

I'm don't blame Goodman for that, just the hassle of the whole situation. God help me if I know why it took that long to pull a vacuum on a 15' line set that was triple evacuated. I've been a...

I had an issue with excessive moisture in a new install recently, and it was quite irritating. What point do you open or close the ballast? Does it add extra time? How effective is this method...

I just had a 2-week string of terrible luck with a Goodman a/c. New unit installed on 6/5 didn't operate on startup immediately, compressor sounded stuck despite being a scroll. When it did start,...

In what way would one use a heat gun while evacuating an a/c or refrigeration system? It was never mentioned when I was in school or any other time during my years on the job until recently. To my...

I was hoping someone could share some techniques for recalibrating manifold gauges. My R-22 and R-410A sets were in storage for a few years, not pressurized, while I was out of work. Recently I...

Thanks for the input guys! :cheers:

Dumb question, I know, but my searches yielded no results. Are tank racks required by law for transporting refrigerant and recovery tanks in vehicles? Federal EPA and DOT websites have also been no...

This makes me sad, but it's worth the wait.

I've been posting occasionally for about a month and forgot to introduce myself. Oops :whistle:

My name is James, and I'm a service tech/installer/metal fabricator in my 12th year of...

Can anyone tell me if the Tech LC bag works well in the field, not just on paper? I'm 99% sure I want one, but I'm looking for feedback/ratings on field performance and satisfaction, just not...

I've worked for Carrier/Bryant/Payne dealers for 12 years and really like the equipment. It's consistently reliable, and when annual maintenance is performed, high probability the furnaces will...

Residential. We also do light commercial, but haven't encountered Lennox there yet.

So many people with Lennox equipment in my area turn to the company I work for now, which is a Bryant dealer, b/c the local Lennox dealers are beginning to treat them bad more frequently. It's a...

Carrier/Bryant/Payne did just that, and it shows in the latest models :grin2:
Lennox engineers seem to get more idiotic as time passes. It seems like they enjoy punishing field techs. The most...

How can someone obtain the wrench if Lennox suppliers won't sell it to you (as punishment for not selling Lennox crap). Is there another way to remove the plug and flame sensor without the special...

Lennox has been a PITA for us lately too. I work for a Bryant dealer in Rock County, WI, and I find Lennox encounters to be useless. We operate in a small town, and we only run calls on Lennox...

Got a call today for too much heat. H/o thinks furnace runs too hot, furnace was operating when I arrived. I replaced the mildly dirty filter, verified blower wheel was clean, pulled blower to...

Call your local dealer and have them perform a combustion analysis. The results from that test will help determine whether the secondary will be covered under the settlement. Carrier offers a credit...

I had time to do research today, and if anyone is looking for parts for these units, I found an online catalog! Thanks to all for the suggestions! Here's the link:
...

Yes, I suggested it to the boss, and he thought it a good idea to keep on-hand. Thanks for the idea! :cheers:

We could, but on a Saturday afternoon that was not possible and the man needed heat ASAP. I'll consider having the one that I removed rebuilt just in case I need it again in the future.

I needed to replace a failed motor (it was original, and it seized due to excessive dust and water exposure), and luckily we had one in an off-site warehouse among antique parts and used equipment. ...

The new primary and secondary hx designs are quicker and easier to access for cleaning or replacement, plus it's a one-piece configuration. After replacing 6 primary and secondary hx in 10 to 12...

I like the new designs, we've installed several in the last few weeks. We're a Bryant dealer, and my boss sends us to our supplier for classes regarding product updates. I attended the class for...

Today I encountered an Economite burner assembly and needed replacement parts. Does anyone know where to locate/obtain these parts quickly? It converts an oil burner to natural gas or LP. Any...

Congrats!:cheers:

No cooling call, I arrive to find a double-bit axe lodged in the side of a condensing unit, no refrigerant left in it. The lady of the house said her husband did it the previous night after they had...

No heat call from a new customer at night. H/o claims blower won't work, he tried to oil it, but it's stuck fast. Told him I'd be there in about 2 hours b/c I was already on a call and about to...

One possibility is a plugged secondary hx, characterized by a powerful sulfuric odor coming from the exhaust pipe or seeping from the combustion chamber when the cover is off. LP fuel applications...

Does the furnace have a dedicated electrical circuit with a good ground connection to the breaker box? I have seen DIY electricians cobble some real head-scratchers, as in "what were they...
