Guess I can’t blame them for that. No need to call in for help to diagnose a bad igniter. Lol.

New thing for carrier. But was told by them today that it only applies to companies that don’t have an account, and homeowners. I’ve had an account for 20+ years so it didn’t apply to us. The women...

Starting this past Monday, 4/9/18, whenever you call Carrier tech service for assistance, they charge your credit card $100.00. This is good for 90 day’s on that case number.

I Googled it tonight.... wow... I see that they are.

Called to a carrier 58MVB080 that my company installed in 2006. Very first service call to it. Exhaust, outdoors smells. Performed combustion analysis and found over 1400 ppm of co at the vent. At...

Get what ya pay for....

Thanks for all the input. Never had to pipe one up. Owner is not doing the antifreeze. Pumps can run all the time on this so it sounds like he will be ok.....again thanks...I learned something.

I'm not sure if I'm in the right forum, but here is my question. I have very good commercial customer who owns a plastics factory, and commercial office space that hires us for everything. He hired...

I agree. Replace everything and go with 404A. Best choice.

OMG!

If there is no problem with the refrigeration I.e. leak, bad heaters etc. I would try a ke2 controller. Much better defrost. http://www.ke2therm.com/

I would check with you local code enforcement. If it is required and God forbid there is a fire, you may have a hard time with the insurance company.

Cheap ones because I keep losing them.

To top it all off the two boilers have aluminum heat exchangers. Water treatment has to be perfect for that. This place is a disaster.

I know that deal. Now I don't feel so bad. My oldest one with Manitowoc goes back to June. Scotsman is spot on. We go online, fill out claim form. Get paid in about 30 days which is very cool. ...

Hoshizaki is really good on hold time. Usually get through within a couple minutes.

They are adding heat to the loop water. Water treatment guy is very reputable but no use treating water going down the drain. Water bill through the roof. Very rich customers... More concerned with...

You mean we can actually get through to a person??? Every time we call we get the same line.....give us your number and a tech will call you back.....that does not work when you are out of town and...

Go with OEM. I try to go worth OEM on everything when possible. Been in the field over 25 years. Spent too much time in my early days trying to make something fit to save the customer money. Any...

Thats one direction to look thanks.

Sometimes the warranty might be different. We install mostly Ruud. Lifetime warranty on heat exchanger. Weathering is the same thing, a little cheaper and I think 20 years on the heat exchanger....

Where would the electrical current be coming from to creat electrolysis ?

Big inn and spa. Five years ago new maintenance man shuts down cooling tower for the winter and freezes the coil. We replace coil. $30,000 job. Poor maintenance no water treatment. Water...

We are Mitsubushi Diamond Contractors in our area. Those wall brackets give acceptable clearance, good looking job. Put a lot of these in.

R22 only. Hoshizaki will not suggest anything but R22. Tell the customer to stick to cooking or serving drinks.

We have put a few of these in with great success. Well worth it. The factory support was great when we had a question about adding a second coil sensor.

School is ok...but nothing beats experience...go to work first.

An update...went to the job site. Put in the proper size overloads. Check the CFM...didn't like what I saw. Pulled the cover back off the fan...guess what. THE MOTOR WAS GOING THE WRONG WAY! Roof...

There are two units. The other is on the roof back a ways. Needed that crane. We actually had to have the power company take down some high voltage lines to set the roof top unit. As far as the duct...

Good looking job! Nice looking trap.

No not plywood, but it is wood which is ok...turning vanes yes.

I had a hell of time trying to purge the oil out of the system with nitro...was almost at the point of cutting the evap...but we got it.

...and guess what, I was the high bidder on the install...

Yes you are right...good thing the insulation covers it (LOL)...this tin knocker decided he didn't want to do it anymore and I bought his whole shop. We do our own now (with a little help from a...

Less than five years old. One is a cooler, the other a freezer. Both of these compressors locked with in a year of each other. I figure due to poor oil return. Naturally when we replaced compressors...

I'm a little embarassed to admit it, but don't know what you're talking about. As far as these RUUD commercial units...love em'. Used to install Carrier...like these better.

These vents are a lot nicer than have two pieces of PVC sticking out of the house (the plumber put the PVC vent for the water heater). They only cost about $25.00.

...and yes, 1" filter...never on...

Tripp....don't worry about it...you said the right thing '...I learned something'. I know a lot of guys who would have ran and said '......wwwhhaatt screw!!!??? ...don't know a thing about it'.

MP 39 (R-401A) should not be used with low temp. I've seen it done, and seen it work, but you should use MP 66 (R-401B). It is a better retrofit for R12 in a low temp situation such as a freezer.

No need to get the furnace any higher. Dry basement. Its actually all finished now into a bar with a pool table, tile floors, a bathroom, etc.
Yard is now landscaped and the cement pad I built is...

Two story office building. Two 10 ton RTU's. Both RUUD. One had to go on the ground and, one on the roof. When the weather got nicer we insulated the outside duct, sealed it up and painted it. You...

We do mostlty commercial and industrial, but here is one of our resi jobs we did at a new house last year. All of our jobs look like this.

Fan is rotating correctly, wiring is correct. Don't know the recommended cfm. Municipal job specced by an engineer. Have to get my hands on the prints to see the recommended cfm, measure it and see...

I love this forum...but it got me thinking...do you think doctors and surgeons have a "Doctor Talk Forum" where they have their own 'wall of shame' area?
That would be interesting.

The only...

I wonder if they were purging nitrogen. Can't imagine what the inside of that pipe looks like.

I wonder what the HVAC guys were doing when the plumber installed this.....
....who needs sheet metal when they got that there flex stuff...duh

We see this crap all of the time unfortunately.

I have been happy with my E450 w/ the 6 liter diesel. It has a Knapaheid utlity body and a crane mounted inside that comes in handy... Utlity body...only way to go for me.

I'm looking into installing a gas fireplace in my personal residence. This would be a new installation where no fireplace currently exists.

Brand new building, new installation, all brand new equipment. Not sure why the motor is overamping at this point. Would like to adjust the sheive to try and lower the amperage, but they want to keep...
