Oddly enough we were talking about this yesterday at work. It still baffles me why we don't use 134 for residential ac. It's used in vehicle ac, chillers, coolers, etc. But not residential ac for...

Rarely do I ever get any ot. Maybe 3 weeks in this entire year had actuall ot. A lot of times I get bored with nothing to do and leave early. A 35 hr week is pretty normal for me. Does suck being...

We don't hang out after work very much. Got stuff at the house to do. We do try and meet up every friday for lunch. Once a month we have a lunch at the shop that everyones schedule is cleared for....

No it needs 500 microns. But thats my opinion.

Sent from my SM-G900P using Tapatalk

No that's not what I meant. Was trying to say that you need better vacuum tools so you can get vacuum to 500 microns faster. The 500 microns isn't your problem. Your tools are the problem and...

If that is the normal type of equipment you work on then you need better vacuum equipment. I've used vacuum rigs that could bring a 450ton chiller to 5mm in a matter of a few hours.

Get a...

I actually don't know why 500 is picked as the magic number but from observations during vacuums there is something boiling off and being removed in the 750-800ish range. There are other things...

Chillers can still use remote air cooled condensers. I'd assume he is meaning the refrigerent lines to the condenser. Still don't know why you would need medical grade. Never seen that except in a...

What is correct about it? It looks like they used a float switch.

I'm looking into controls. If you really enjoy duct design you could move in that direction. Would take some college but with a solid hvac background and a degree you could be designing duct...

You better start looking at getting a degree then. Or possibly move to being an estimater. Then we can all be cussing you when we are wondering how to make your drawing match up with the jobsite...

If you ever find this holy grail of no crawlspaces, attics, or roofs please let me know. I'm actually researching a carrier change in a few years to get away from them.

The owner of my company is the son of the founder. He started in install when his dad ran everything and actually knows very little about service. He also has a business degree. I'd say his...

Trick there is don't get to technical with the homeowner unless they are an engineer. Simply saying it's your ductwork causing your issues because it wasn't designed correctly. Is usually good...

Hey that's actually clever. Moore Mechanical. Cool play on More Mechanical. I will agree with the people saying use your name. Look around your area at the older established businesses. I'd bet...

Honestly you need service and install if you want to branch out on your own one day. Most places in my area will start you in install though before moving to service. We just picked up a kid fresh...

Picture? What picture?

I had a similar issue on a hanging heater. It ended up being the wire from the board to the sensor. Even though wire actually read continuous. That unit about drove me bonkers. I've started...

Yea I've seen those excuses for duct systems before. They are pretty bad. But they are cheap and quick. Usually see them in lower priced trachomes. If you can get a static you will see it is...

We only do these during slow times of the year as promotions. We do look at the entire system though. There are a lot of things other companies might miss. So say the other guy diagnosis bad...

Best investment ever! Owner has decided to buy 2 more setups so everyone can have one. 6 cfm pump and megaflow hoses and crts and WOW!!!!

What kind of pump doesn't have a 1/2" or 3/8" connection?

Does it really matter? All we are waiving is the service call. If gaining a new customer what's more important? In this case i can guarantee i wasnt the first on it. About 99% of them are "i was...

Well this thread has really mophed. Goes to show that more than just size and staging goes into a system. While a system does need proper duct design i think the general consensus is that for a...

Actually have gotten a few new customers by doing it. Mostly repairs where another company condemned a perfectly good unit. This is the first wierd mess though.

So current promotion we have is a free second opinion. And boy did I get a doozy today. 94-95ish rheem package heat pump. Has a brand new scroll 3.5 ton compressor in it. No model or serial on...

The cost to install one and have it operate correctly will far exceed any money you spend on the electric bill. Opening a window and using a box fan would be much cheaper.

It's called an economizer.

In our area most units are oversized along with the ductwork. A properly sized 2.5 ton running 24/7 when outdoor temps are at design will be much better on the equipment and the electric bill than...

Sounds like you covering all of it. Shoot if you eliminate exhaust, intake, condensate, and draft motor. You're really only left with one other option.

Sent from my SM-G900P using Tapatalk

I'd be back to rechecking for restrictions in the exhaust or intake then. I mean maybe there's something you can't see easily. You've covered everything so its the best bet on having a problem that...

Have you checked the condensate drains?

Sent from my SM-G900P using Tapatalk

I'm not saying to oversize a system and allow the staging to make up for the oversize. I'm saying a properly sized system is oversized the majority of the year in most areas. Staging helps prevent...

The point behind staging is if you size an ac for 95f outdoor temp but you only hit 95f for 1 or 2 months out of the year then the rest of the year your ac is oversized. Staging works to make it...

I believe most manufacturers are coming out with them. Not all are a true full variable compressor but they are still multi speed inverter drive. For example ruud/rheem is inverter drive but really...

It is always worth it. Your ac and heat are both oversized for the majority of the year. Even sized properly you don't always need 100% of your heat and air. Staging really helps solve that...

Hopefully you learned something from this experience.

If you can jumper r and o outside and it will energize the reversing valve that eliminates anything in the unit. If you jumper r and o at the stat that should tell you if it is the wire or the stat....

There are quite a few that are mix matched per say. Usually see more systems with micro channel condenser and tube evaps. Just lately been setting pack units where both coils are micro channel. ...

What about basic honeywell pro 8000 stats with the wifi interface module? Can also use redlink remote sensors with them.

We have set several rheem micro channel units. Haven't had any issues with them yet. Do you recall what the issues were? Symptoms? Customer complaints?

Sent from my SM-G900P using Tapatalk

Yep. Of all ceiling damages if I'm remembering right only a few were from failed float switches. Many have been from aux drain setups.

I am not sure why it took so long but I'm glad it is finally here. I'm sick of telling homeowners their 4 year old unit needs a new coil. Btw there are ways to fix em without the epoxy and clamps. ...

We seem to have really good luck with rheem. Yes you should read the instructions though.

Im with you as well. Much prefer having a little light after work in the winter. I've yet to run across anyone who will admit face to face they like the time changes.

Micro channel isn't that new of a technology. Go look at the ac condenser on your vehicle.
