Thanks for the help. I'll keep an eye on it.

Would it switch to EM Heat if it was in defrost mode?

It was in "Em Heat" mode when I came home from work today. I just manually switched it over to Heat. I don't remember ever seeing it run in "Em Heat" mode before. I don't know if it switched from...

Welp, I guess I am a moron. lol I just raised the temp to see what would happen and I do see the "Aux Heat On" message under the Set to temp. (With the "Heat" system setting.)

I guess Em Heat has...

Hello all.

Since 2008 we have had a dual fuel setup with a Trane XR-14 with a gas furnace. When it got really cold, the thermostat (TCONT803) would display AUX HEAT. 1 or 2 years ago, the...

Thanks guys. I'm pretty sure my overall energy costs are less this winter than last, but it's hard to quantify because we had a 500 gallon propane tank, and I'm not sure how much propane I was using...

The winter rate is actually a little lower than the summer rate.

My usuage is a little higher. About 6 Kwh more per day now than in August. In Aug I paid $113 bucks. And the bill I just received...

System: Trane Xr14 heat pump with XT90 gas furnace. (Hybrid)

Hello all. Been a while since I been here. Hopefully you can help me out. My system was installed in July. The last couple of warm...

Thanks for the help guys.

I have not noticed any issues since then. And all the settings and everything appear correct, so the defrost seems a likely option. It's good to know I don't have...

I guess it's possible. I have no idea of the conditions required to frost the coil.
Seems odd to me that it would freeze up at 40 degrees. Then again, I don't know much about heat pumps.

This morning when I woke up, the outside temp was 38 and the heat was operating in HP mode. I still have no idea why the furnace was on the other day when it was 40 or 41 degrees outside. Who knows,...

Yes, the outdoor temp sensor is hooked to the t-stat and it shows. I went through the setup numbers and everything looks ok as far as I can tell.

Setup# 170 set to 7 (2 heat/1 cool)

I think I understand what you mean, but it never got near 35 last night. I'm pretty sure 40 or 41 was the low. Seems to me the furnace should have never kicked on in the first place.

Just as a...

Hello all.

I had a dual fuel system installed a few months ago. A Trane XR-14 heat pump with a XT-90 furnace. I had propane when the system was installed in the summer. I recently converted to NG...

Dang, I guess this isn't as cut and dried as I hoped. Is the "low temp cutout" the same as the switchover temp from HP to the gas furnace? I guess I will just play it safe and not use the heat yet...

The system was originally set up to run propane. At the time, I wasn't sure if NG was an option. I inquired to the NG company and they extended the main line down the road a little to reach our...

I recently had a dual fuel system installed. I originally had propane but am switching over to NG. Unfortunately that switch is not complete yet. Still waiting to get NG meter set. Have been using in...

Is it possible you have the fan set to circulate instead of auto? I know if I put mine on circ it will come on at random times to help circulate the air.

I had read some stories on here about people upgrading their system and not really seeing any reduction in the power bill. Or even an increase. But my old AC was probably 30 years old, so pretty much...

RE: XR14 heat pump w/ XT90 furnace

Trying this again... I don't think my first post worked. Mods, please delete that other post. It shows as blank to me. :confused:

Just got my first full bill...

Thanks to everyone who responded.

They did put a sticker on it saying to use R410. It's right beside the factory label with the model/serial number that has "R22" on it. But if somebody wasn't...

Thanks. I hope this is the case. The person I spoke with from the company that installed it said it would perform exactly the same. But if they couldn't inform me of this change during the install, I...

I called the company and that's exactly what he said they did. Changed out the TXV. He said the R410 coils were back ordered at the time.

So, how does this affect performance? Will the R22 coil...

I just received my warranty paperwork from Trane. On it, they list the equipment covered. I checked the serial numbers, and this is what they installed.

No problem. I'm just trying to be an informed consumer.

I'm sure the HVAC company will have their preference. But as we all know, sometimes their preference isn't always the best choice.

Would...

It's not DIY.

Currently my furnace is set up for propane. There is a copper line feeding it. I am going to be switching to NG and the new line will be coming into the house in a different area. My question is,...

Ah okay. Thanks.

How do I determine the COP for my heat pump at certain temps? Thanks!

Maybe it's better described as a bulkhead. :confused: It's the area above my kitchen cabinets that is closed in.

Thanks for the info. I'll go ahead and seal those seams.

Do these type of seams in duct work need to be taped or sealed? I am trying to make sure all the duct work I have access to is fairly tight.
...

Yes, typical 2x4 studs with drywall. I think they are 16" on center. Sorry, I forgot to mention that in the original post.

Unfortunately, running the duct/flex along the garage ceiling will...

I am going to have the HVAC company add a return to our master bedroom. Obviously they are going to offer suggestions on how to accomplish this, but I wanted to get some ideas on how it’s usually...

I'll be safe and leave it as is. I don't want to screw up my septic system. They are even more expensive than HVAC equipment. :D

1. Would it hurt anything to have the condensate drain line empty into the washing machine drain that empties into the septic system? I didn’t know if the acidic nature of the condensation would...

Nevermind.

Does your digital camera have a macro option for up close shots? That may help.

Lance, I'm just a homeowner, so I don't want to give you any wrong advice. Hopefully a pro will chime in here soon.

My old condensate line was just a gravity feed pvc drain pipe that emptied...

I'm certainly no pro, but when this happened to me, the condensate drain was clogged. I just put the shop vac on the end of it and it sucked out the clog and the rest of the water. Not sure if that...

Hmmmm possibly. Would that take care of the supposed vaporizing problem from just having one 120 gal?

I am hoping since I will be using the heat pump for the majority of my heat that a 120 gal (or...

I called another propane company to ask them about it. They said you could use the 120, but if it got very cold, there is a chance the propane wouldn't vaporize correctly.

I was really hoping to...

I was told by the propane company that you can't run a furnace off of a 120 gal tank. Is that correct?

Now that I have a heat pump, I was really hoping to get rid of my 500 gal tank and go to a...

Wow, I think I'm finally starting to get it. :D I think the main problem was, I didn't understand the difference between non direct and direct venting.

Looks like the installers will be running...

So then what the inspector was saying is true?

Thanks.

I read the install manual and it did allow it to be indoors as long as it wasn't a confined space. Might be hard to get them to move it when the manual allows for it. Then again, they might have to...

That's what I thought. It made no sense to me.

No the vent pipe is off to the side about 15 inches. The disconnect box is behind the condenser.

Is there code to how close the vent pipe can be...

RE: "Pics of install - let the comments fly" thread.

The city inspector came by today to look at my heat pump/furnace install. He said the exhaust vent pipe is to close to a window and he would...

Still not a DIY job.

You are very wrong. I am fairly handy when it comes to DIY, but I wouldn't have a freakin clue where to begin on a HVAC install.

The reason I mentioned moving the dryer vent myself is that I don't...

Gasolair, thanks for the very detailed response. You are correct about that side of the house being busy. There are 2 windows, a door, a screened in porch and the regulator for the propane. That...
