That unit is a solder in unit, so no field installed flares, unless they used a flared filter drier.
He may be calling the TXV connections flares, which can leak from factory.

I think that in a new install, new construction, the residential is so cut throat, you would lose jobs. That may be the mentality that contractors have towards your question. Run it in sch 80 PVC,...

What are the temps on all four pipes of the reversing valve?

That wont be a problem for us! We have multiple gas furnaces in our classroom.

We use the TruBlu kits at our HVAC program where I teach. They save valuable lab time!

My next van will be solid panels in place of the windows for sure, keep nothing important in the cab, everything locked in the back. The slick locks do work. Cant be pried off.

I have reached out via the contact form on the website. I had a conversation with my Dean, looks like he would be willing to green light the event. Hopefully I hear back soon.

Thank you for...

Is it just the recertification that is virtual? I have been wanting to go to the 3 day class (waiting to hear back from NCI), they say 2 days instructional and the 3rd day is testing. Is this how...

NCI is great, but no classes available right now...
Do they publish a textbook?

I will now that I know it may be possible to host a class.

Understood, I will look for contact info on the website....and then see how to add to next year's budget request.....

I'm pretty sure we have the space, I teach at Tyler Junior College, so is ten the minimum amount of students needed for a class?

Do you who at NCI I would need to contact? I must have missed that...

Does anyone know when NCI will start giving classes again? Currently it has online instruction for those who wish to renew the certification, but I do not see the 3 day in person class listed on the...

Here, I am not allowed to even run the gas line to the furnace. Code states that as HVACR contractor I can install the furnace to the provided gas shutoff. Similar on the electrical side, we can...

So how long does it take to do?

Start there, in your area of the country, are your competitors doing a CA every time?

If you suspect low subcooling
1. Find the leak
2. Find the leak.
3. Recover refrigerant
4. Pressurize with nitrogen
5. Find the leak
6. Read the install manual
7. Calculate how much charge to...

Isnt that what the helper is for?

If I can, I tape first then put that thing in the closet.

I have the G5 twin. Only problem I had was when I turned it on with the recovery tank valve closed. It sprung a leak in the condensor, which was VERY easy to repair myself. I have used the G5 twin...

I have had this happen to a hanging propane furnace in a greenhouse. Furance is way oversized for the space, we had to bring in fresh air to avoid starving the flame, now I see why it has the...

I thought the vibration was at the Air Handler?

Oh, and always charge enough for a job to be worth the headaches it will cause, that way if they do say yes, the extra money is there.

Depends, is the furnace safe to operate? Is the heat exchanger in good condition? Cant answer those questions without moving the water softener. As others stated, include that work in in your bid,...

These are builders models for the track home market. You know, the subdivisions where all the houses look the same just flipped the other way.

Are waterless traps code compliant?

AmRad capacitors. They also make the Turbo series. Pretty much all I install now

That would be collusion.

That would not be covered, that is owner negligence.

I met a guy at a conference who does the testing. He charges 150 per hour, stays on the job with the crew so they can seal and test for pass. Now this is part of his home energy business, coupled...

With the right duct blaster, you can do the residential test, but as far as what test standard to use, I am still looking into that. The Minneapolis Duct blaster has interchangeable rings to be able...

You are right, the leakage should be small, but how many installers out there actually do it right?
I have heard of California going for a super low allowable limit for duct leakage, causing the...

My jurisdiction goes by the International Energy Code of 2012 or 2017. In that standard, all new air moving systems, whether residential or commercial shall be sealed. This has to be verified by a...

If you have any questions about ductwork, get a duct blaster test done. Only way to prove the ducts don't leak, now the test does nothing to address undersized or oversized (very rare) duct systems....

Turning the system on off repeatedly from thermostat also causes damage. Hopefully your system has a protection circuit for the compressor. explain to the next tech that they may need to stay awhile...

Have your new tech check the outside unit for proper operation in all modes.

Good to hear he did the right thing.

Replace.

When you find an actual qualified tech, let him know that little breaker has tripped multiple times, it will need to be replaced as well. But unless this system is ancient, it is fixable, and it is...

According the most residential building codes, you will need to have a Manual J Load Calculation done. This is required even for system replacement. As far as the furnace, an 80% is just fine, maybe...
