"Need" is kind of a strong word. They certainly "should" be trapped and sloped towards the traps and/or compressor. It depends on pipe sizing and length of runs. If the suction line is undersized...

No, I do not know of any reports of anyone who actually used or wanted to use this energy tracking feature. I've had the same thermostat installed on my furnace for the last 7 years, and personally,...

Yeah, quit looking at it. Yes, your thermostat does have this "feature", but all it was ever meant to be is a fun little toy that you can show off to your nerdy friends in order to impress them. ...

Call your dealer. They usually have their own tech support guy and are supposed to be the first line of defense. They will give out the number (or put you on a 3 way call with them) if their tech...

Who cares? Install an expansion tank or one of these things and be done with it...

....of their technicians and installers. It's hard to find good help these days.

I would guess that your A coil is probably OK. If there were dirt/dust to plug up something, it would get to the secondary heat exchanger first, which was changed out. Also, I would guess that...

I heard that Elon's plan for more efficient heating consists of light bulbs that provide heat at the same time that they provide light. Most light bulbs are made out of diodes that produce very...

Interesting. What do these sensors do? I'm guessing control outdoor fan speed, or does it have something to do with defrost?

Yes, that is standard practice.

Last summer I was told that a couple of residential type air conditioners that we installed were finally wired up by the electricians and ready to start. My apprentice and I got there to find...

The fan inside of the humidifier is not taking furnace room air and trying to force it into your ductwork. It takes air from inside of that duct and blows it back into that same duct. Here's a...

If by flex you mean CSST, then I don't see any reason why it wouldn't be alright (as long as the inspector is OK with it).

If you mean some kind of pre-made flexible connector, then maybe not.

How many amps is an orange wirenut good for? (That's what I normally use) :whistle:

I highly doubt over-charging has anything to do with pin-hole leaks. Have you ever worked on an outdoor refrigeration condenser? They are made to be pumped down, no matter if they have a micro...

Ahhh, we're talking about bronze brazing rods here. I misread. When I saw "flux coated", my brain instantly went to the blue or orange coated silver rods, since that's what I am used to. It helps...

A few years ago I dropped an old Revere pot and cracked it's rim. I smooshed it round again and brazed up the crack with 45% flux coated rod and it seemed to work just fine. I used extra flux,...

Ask her if she knows about the "trace amount of plastics" that's in bottled water? :whistle:

I was going to say pretty much the same thing that chander said. The brass parts inside of faucets,...

I have a walk-in cooler install to do that will need a condensate pump. There is no good place to put the pump on the outside of the cooler. Is it OK to put the pump on the inside of the cooler?

Are you sure there's no exhaust fan on the roof? My guess is there probably is, maybe with an exhaust grill in the hallway? Perhaps the make up air isn't working and is just getting air sucked out...

I don't know anything about airplanes, but this one was a "Bellanca Viking". I haven't heard the year, but Wikipedia says they were made in the 60's and 70's. The pilot is a competitive aerobatic...

This happened a couple of days ago on I-35 in Minnesota. Small airplane had engine failure shortly after takeoff and couldn't make it back to the airport, which was just a few miles away.

It was...

What's a "duct AC"?

If you meant to say "duct-LESS" AC, then you most likely don't have a "high side" port. On those, both pipes are on the low pressure side of the system and there usually isn't...

I'm with you except for the copper part. Furnace condensate eats copper. It has to be something else. Stainless tubing, maybe?? I've never worked with or seen the stuff, but I believe Propress...

Best option would be DO NOT EVER install a high efficient furnace in an attic. Seriously. Get that thing out of there, unless you live in a place where the attic never gets to below freezing.
...

Just got done watching "The Joker" movie yesterday. I thought it was a pretty bad movie, as far as Batman movies go. Not a whole lot of action, and it was mostly just a long depressing movie that...

Are those belt drive compressors? I didn't know belt drive compressors were actually still used anywhere anymore. About what year are they from?

Did the system have a lead-lag system before,...

Hmm What the h... [are you talking about]?

..is there -question someplace???[!!]

I had to think about this one, but I'm pretty sure a radiator is technically a water cooler. Maybe you could call it a "heater water cooler". Oh hell, I give up. Call it whatever the eff you want.

A few months ago a guy lost his marbles and went off on a bunch of us for using the word "Freon". I think he might have gotten banned over it. In my opinion, using the correct term is important,...

Just a few little nit-picks...

-Not enough pipe supports, especially on the gas line.
-No dirt leg before the gas regulators and/or boilers.
-Relief valves can't be replaced without cutting the...

I heard that the room where they're made is pressurized with 78% nitrogen all of the time, so that's how they do it. By the way, have you ever noticed how it smells like tacos when you take out...

I despise twist ties. When I was 19 I was thrown in jail for driving like an idiot and getting pulled over too many times. While in jail I got signed up for their work program or whatever it's...

It's Microsoft's cloud storage that they are trying to get you to sign up for. I don't know off hand, but pretty sure there's a way to get Microsoft to quit bugging you about it.

I believe most have a plug or a knockout in the damper blade that you're supposed to remove if you have a standing pilot.

Whoops, looks like my post was 2 minutes too late. RLJM beat me to it. ...

Sounds to me like either your TXV's powerhead is bad (or wrong), or your superheat thermometer is out of calibration.

I'm thinking the word "cast iron" might be a clue that this thing isn't direct vented. Is there such a thing as a cast iron direct vented boiler? I believe most are natural draft with a vent hood. ...

How about instead of asking the SAME question over and over and then getting mad at the well thought out responses to your question, you try asking a different question? Perhaps something like... ...

I'll give you a hint...

If you (or better yet, someone who understands electricity) would like to isolate the nest (and/or a separate transformer) from the furnace's control board, then NONE of...

Some thermostats have a fan "on" setting, as well as a "circulate" setting. Fan "on" will be high speed, while "circulate" will be a lower speed. Also, sometimes the "circulate" setting will turn...

Some low water cut outs are made just for steam, some just for water, some are approved to work with both. Either way, the wiring is about the same with either type, and should be easy for someone...

I believe California passed a code a few years ago that requires emergency back up power for any new building that has an elevator. Does this mean no more natural gas to power the emergency...

Fracking is good because it gets natural gas and oil out of the ground. Natural gas and oil are both toxic substances that you don't want down there. You're actually helping the environment by...

-Get yerself a wireless thermostat (Honeywell Redlink) and a wireless sensor.
-Wire up your new thermostat in the same location as the current one.
-Mount wireless sensor downstairs wherever you...

No, most systems do not come with a start capacitor. I don't think they ever did, except for maybe the top of the line units. You can not add a "booster cap" on top of an existing start capacitor. ...

What kind of problems? I agree that an OEM start relay and capacitor specifically matched to the compressor is always best, but in my mind, a universal hard start kit is still better than no hard...

What? I think this is the first time I've heard this opinion. As far as hard start kits go, I thought Kickstart was top shelf stuff. They are at least better than the Supco and other brands that...

For someone who claims to be educated, your grasp of the written English language does not seem to be very good. For example, what do you mean by "Isn't starter cap basically supposed to be "the...

Wow, that is alot of money. I was thinking a couple of gallons of diesel for the back hoe that's already on site, and maybe whatever it might cost for the plastic tubing.

I would imagine that if...

I always wonder why ground source heat pumps never seem to gain any popularity. I admittedly don't know much about them, but it seems like they wouldn't add much extra cost if they were installed...
