kermy,

So true! Next time I have this dilemma, I'm going to ask them to fill a large glass with water. Then I'm going to say you have 2 seconds to drink it all... when they can't, I'll ask them if they...

What kind of unit is that where they still run the refrigerant lines through the cabinet?? I HATE those!

Bet if you tossed a fire cracker in the exchanger...

Geez! Just wrap it with some solid strand 10 gauge copper wire and be done with it LoL!

The tech who diagnoses your problem with that unit needs to have good knowledge of Lennox equipment. Could be a venting problem, a draft inducer problem, board problem, flame sensor problem, or...

Well they're gonna have to have an onboard speaker on those non-clicking thermostats so the technician will be able to hear when it calls... kinda like the click on camera phones... lol

Ok, some of those sensors have to have a special shielded wire ran from them to the thermostat... If that's not the problem, your sensor might be bad. Must ohm the wires open and then with sensor...

The problem is the furnace is wet;) Wait for it to completely dry before trying to use it again.

Think wind blowing through trees. That there filter is too good for your return design. Also, alot of people do not realize how having a 'good' expensive filter can make unfiltered air more...

No, they have never gotten stuck to where it blows out the charge in the hose for me. But sometimes the pressure pops the o-ring out, and sometimes damages it, and you have to ease it back into it's...

I bet if there were a designated oriface for the bulb to go into, it would always be installed properly. LMAO

That's a Square Dead box isn't it?

I think your tech knows what's wrong;-)

So THAT"S why the bottles are pink!! 410A systems are ultra sensative.

I've noticed that it's much more difficult to spot a problem on a 410A TXV in the earliest stages of it's failure. Pressures are so close to what they are supposed to be! Most of the time for us,...

Awesome! I remember a few Rheem package units LAYING on top of the unit soldering in a compressor, suction and liquid line driers and such UPSIDE DOWN because there wasn't room to 'get in'. I'd...

This has been my experience.

Perhaps they changed out the 'guts' and left the old coil box with the original data sticker?

Ask them about the TXV.

Call an electrician!!!

If only they could make a condenser look like a tree, maybe people would stop trying to hide them...

Dick Cheney must work in that office.

Ma'am, were gonna have to schedule your tune-up for tomorrow! lol

The elecricians always put the darn disconnect in a bad place when the high voltage wire comes out of the wall like that. And I can see the unit used to sit alot closer to where the lineset exits...

Do 2-speed units have this problem when running in LOW speed? Think about it...

Wow... WOW! Sounds like alot of on-the-job training;-) Well hang in there, and good luck! The new employees always get the difficult and dirty jobs like that in snake, spider, and creepy crawler...

I didn't know BP made PVC fittings!!

Too much work and not enough play time?

That thing must be a limited edition because I've never seen or heard of an HS31 either. Collector's item I guess! ;-)

Yes, Lennox NEEDS to do that! I hate wiring up the harmony zones with humiditrol, EDA's and ERV's... oh, and add in the April Aire fresh air controls and damper while you're at it! lol... in a 130...

I've noticed on an undercharged system, when the evaporator coils isn't 'full', the suction line temperature is the wetbulb temperature. But the coil has to have condensate on it already to get the...

Well, it could be a small amount of air being drawn from around the edges of the cabinet panels, disconnect switches, or lineset cutouts. You would be suprised how much air can be drawn into the...

It's doable, but opening up the system at any rate is risky at 30 years old. It's worked like that so I see no need to know what kind of pressure drop there is across that section. A single pump...

7/8"?? I bet that's 3/4" LoL

Yes, it does a number on cork tape with tar... makes one hell of a mess... trying to get it all off without getting gooey goop everywhere is almost impossible, but at least it was obvious where the...

Are you positive your S/A reading is accurate??? One time when I was an installer I got a 30+ degree split on a slab coil lol, and I was a little concerned about it, but then I found out there can...

Gotta have that turbo button! lol

That low pressure switch is very important in certain circumstances. I've seen a few Lennox systems right at or past the 10 year warranty lose charge and run too long without refrigerant. Most...

Where's the #3 N.O. terminal tab on that DPDT relay? And what shocked the control box there??? Something is amiss!

I second that contactor replacement ;-)

Don't believe it's wrong until sparks fly! lol

It would probably be good to sit tight until you get used to your new thermostat. Chances are, the reason you changed it out is the reason it's going to seem "different". And, more than likely, the...

You don't want to do that. I've done that, and I don't enjoy doing that!

Fixed orfice, hardlined suction pressure.... I think you're right, it's dirtier than it appears. One trick I know of is brushing your fingernails over the coil fins, and if the fins ring, it's...

It's a.... DEHUMIDIFIER!!!

Yes Sir! Heat Pumps occasionally make my temperature and pressure go abnormally high... this shall pass once you meditate and focus;-)

Aside from watching for generic filters, alot of the times in alot of cases, a 20X25X5 filter doesn't actually measure those dimensions. Measure the original filter, then match that with 'actual...

wow... really need more info. like what was the customer's reason why you were called out? it does sound like a restriction in a way... did you check the bi-flow drier? reversing valve? which...

I have only seen one second stage 18-24 Volt internal solenoid fail (open winding), and heard of one other failure... both of these 410-A units were less than one year old. I hardly think it's...

Could be broken loop in a safety device circuit. You probably don't need a manual... just a multimeter. Good luck!
