Good to hear that I'm not the only one swearing at the York heat exchanger replacements. They have dozens of screws, some right against the bulkhead, insulated or taped over and the rest rusted away....

I went to the PDF figuring it must be some confounding miasma of technical information. The solution fairly jumps out at you and the document is so well laid out I printed it for my apprentice for...

I'm using the Blackberry Playbook, it pairs via bluetooth with my blackberry so they share data as well as the blackberry's data plan. Since I do all of my reporting and quoting online it's nice to...

I went further down this road and upgraded to the latest version of Rover hoping this would fix the problem. I downloaded the latest drivers for the Quatech card (comm 4), none were available for the...

I have had to move Tracer summit and rover twice, once when my hard drive died and again when I upgraded my laptop. The procedure is pretty straightforward and the same as moving your customer's...

Ever since Carrier got the great idea of putting oversized ceramic fiber gaskets on their combustion blower housings I have been dealing with the effects of fouled fan wheels contributing to...

I'll take my rain in January over -35 in a lot of the country. The winters I spent in Toronto weren't so bad, it was kinda snowy but the hot fog coming in off Lake Ontario all summer was the killer....

With the dollar above parity with the US and a new journeyman making around 100k it's hard to imagine heading South to be a very small fish in a big pond. Maybe once you have some marketable...

Come to Vancouver, lots of work and definitely warmer albeit wetter.

The overall temperature drop over the evaporator is lower with one stage running than with two. With the second stage running you have another circuit pulling heat from the airstream so the OVERALL...

Exactly that, there is some organic growth somewhere in your system. Whether is be mould growing on a dirty cooling coil or standing water in the drain pan growing slime, something isn't quite right...

One thing I would add is a check valve at the pump in case the breaker trips or someone pulls the plug while you are out for lunch or overnight. I had someone pull the plug on me and came back to the...

Worse still Lennox makes valves that look exactly the same but all that you find when you take off the cap is a spring with an operator cap on it. You can get a replacement from Lennox for less than...

In your hypothetical "charging from a duster can" scenario I'd be more concerned that the refrigerant destined for a refrigeration system goes through more stringent QC than that destined to blow...

you do with Lennox's terrible pink txv's with the rounded cap on the bottom. If you take the cap off you lose all the gas because the adjustment takes a hex key but the hole goes through the adjustor...

I will check but it doesn't much matter, I turned them up when I got my new cutting tip and they are set far too high for most of the tiny tips I use. I just crack the gas, fire up the torch and open...

My favourite for sensitive jobs is oxy/acetylene with a small rosebud tip. Connections up to 7/8 can be made very quickly without the valve getting hot enough to make the wet rag steam. If I try...

I doubt that the OEM is miswiring the units causing them to fail. Typically when I see a run of PTACs losing their compressors it is because they have been abused/neglected either through improper...

That is so funny, you just made my day. I'd really love to know what the situation is with that guy. Either he bought a compressor off the back of a truck and is trying to hack it in or he's a bean...

When someone's first post as a newbie in a general forum is to ask technical information about a screw compressor that nobody will know off the top of their head then berate people for being...

Were he someone entitled to that information Trane would give it to him in 2 minutes, a check of the comfortsite would yield it in 5 minutes. If you can't figure out how much oil to put in it, what...

That attitude will not get you very far in these forums. Call Trane back and explain to them that the compressor that they sold you has no oil and no literature. I'm sure that they will help you out...

It's a horrible design, as soon as the econo gets some dust in it the gears bind against the sheet metal and the actuator dies or the gear hubs strip out. I have made the repair by replacing the...

I've spent a lot of time on hold with Lennox tech support to find solutions to problems that are not documented in the IOM for the Prodigy board. The tech support folks are hit and miss with support...
