The other possibility is that your installer set the heat pump lock out or "balance point" to high setting. This setting locks out heat pump operation below the selected set point. So for example if...

Yes based on that you are using ALL electric heat. Have you noticed the outdoor unit is not running??

Scroll down through the menu and look for the block that says "heat source" and make sure it...

From the main screen touch menu in the lower right corner then touch energy tracking. This will give you the option to view usage and inter how much you pay per kWh.

This is explained on page 22...

To my knowledge the weigh in method is the most accurate method to charge a system. The problem is you need to know the exact line length. Super heat and subcool verify, troubleshoot, and aid in...

The Carrier 25VNA0 is a green speed unit and as so has an charging section in the installation menu. When the weather outside is warm enough it will tell you how much charge to add. if this was done...

Charge listed on the rating plate is for the unit and 15ft of connected line set of the proper size and the matching coil(in some cases). With York and some other brands there is also a compensation...

Why not just install a WaterFurnace Geothermal system. With an IntilliZone2 damper control system. One of the options with this set up is for a first stage call to satisfy by just running the blower...

Just had a very similar problem with a Nest hooked to a Lennox gas furnace. I am getting 14 volts on the Y terminal with only the sub base installed. It pulls the outdoor contractor in as soon as the...

Do you really think the compressor would live long enough pumping water to accumulate that much water in the coil. For it to get in the condenser coil it would have to go through the compressor....

Just a weak spot. Finally gave out. If nothing else was found I would not over think the problem.

Best zoning system Ive ever installed or worked on is the carrier Infinity. Using all Infinity equipment and carrier dampers as well. The system lets you set air flow limits for each zones and runs...

Not that I endorse it but there is Aluminum line sets available. There is also a soldier that will join it to itself as well as join it to copper or brass. I know this because my company used this...

"Hot Water High Limit (Domestic Hot Water Option)
This mode occurs when the hot water input temperature
is at or above 130°F for 30 continuous seconds. The DHW limit status LED on the unit...

Expert recommendation...... Leave it to the experts. Thats how they make a living.

If it were my house I would have it replaced because thats what the expert recommended.

UEI DTH31. Been using the same one for years. Only thing I have ever done is replace the battery once a year.

Work looks amazing (with the exception of the source piping) but Kevin is correct. You are not supposed to hook a hot water generator to a gas water heater.

Try taking the UI to the outdoor unit. hook it to the unit with a short piece of stat wire. Leave the wire running to the indoor hooked up inside and outside but remove the stat wire that went from...

are you zeroing the meter to atmospheric pressure before you stick it in the duct?

Check the stat wire you have running to and from all the Infinity connections. The green and yellow are used for communication and if you have any splices that are not 100% or have been exposed to...

H-10 is the gold standard of the industry. It has never let me down. If it says there is a leak. Then there is a leak. I too like to visually verify but I have learned to never doubt my trusty friend.

Im not familiar with that particular leak detector. On the H-10 the low, med, and high reference the leak rate not the sensitivity. So the Low setting would be most sensitive setting.

Yes put a few oz of r22 gas in the system. Then fill to a good pressure with nitrogen. If you have a H-10 try searching on Medium first and if that does not come up with anything switch it to low.

This by no means is meant to be a training tool. I only posted it in this "Tech to Tech" forum because a few people had asked about how the material was joined. The guy doing the soldiering was a rep...

Let me explain how things are done here.

We have crews that do nothing but run line sets, PVC flues, and set equipment. The service department does the actual start up of the system. The systems...

Well I didn't find the plug inside the line set but all I can figure is something must have been loose floating around inside it. I cut the lines into 2 foot sections after I pulled it out and still...

Its on a Carrier 2 ton condenser. The line set is 3/4 suction and 3/8 liquid. I went back in with the same size. Even took the exact same rout through the house. Only took 32 holes in the drywall....

I checked ever inch of the line set. No kinks at all.

Not sure where the stuff is purchased from. We use a solider that can join aluminum to aluminum, copper, or brass. Below is a link to a demonstration video.

Yes Aluminum. My company gave it try. It was in an effort to cut cost. They have since changed their minds and we no longer use it.

I love a good challenge and the chance to learn something new. But this one was ridiculous.

With the correct charge weighed in the suction would pull into a vacuum after about 30 seconds and the...

I use 2 of the methods mentioned above and have had great success with them both. The dye works great on the formicary corrosion leaks at the indoor coils. During the summer you can usually see the...

Can I get some opinions on liquid line solenoid valves? Installation location, purpose, wiring, and some experiences both good and bad.

I know they are recommended on long line set applications....

Sure. But not likely this "Grand Canyon" crack appeared at the same time the blower was replace. With no symptom of the crack before.

We have had the same problem at my company only it is with Zonex damper control boards. It is only on duel fuel set ups and is completely random. Even to the point that we have the set up on the...

If its the roll out and not the limit I would not think it has anything to do with the blower and board replacement. I would be looking at the HX and venting.

I have had this happen to me in the past also. As long as the high limit is shutting down the heat strip before it gets hot enough to melt the wire itself it will continue to cycle. If the customer...

Man I thought I was installing a space pac system. They must have given me the wrong unit out of the back of that truck???

Vibration isolator.

I think that is the greatest thing I have ever seen.

We also run warranty calls 24/7. Our home owners are told on the phone if the problem found is not under the warranty (i.e. installed their own stat) there will be a charge. And if they refuse to pay...
