We ended up getting a plastic cap and putting it in its place. The screw we had from another valve wouldn't fit. I was thinking the screw is only to keep someone from tampering with the pressure...

Today one of my employees was on a call and lost the cap. What have you done in this situation? I know we aren't the only ones to do this... :oops:

That is just outside the air handler in both the supply and return.

I haven't double checked the airflow with temp rise method. We pulled the piston yesterday and checked that. The Teflon ring was down inside of the piston housing. We corrected that and pressure...

24 is the cabinet width. The B at the end designates a 5 ton coil.

Also the TESP is 0.2 without the filters and 0.6 with the filters.

We came out today high pressure switch was tripped. Pulled the pureatech filters and dropped static to 0.1-0.2 in WC. Head pressure still rising in heat. Its running 265 head and 45 suction with ssh...

If you have constant discharge air at 55° then yes it will increase your energy cost to raise the thermostat if you are conditioning the air with reheat. It really boils down to what type of system...

I use the same clamp with my Fluke 16 and it has a loose connection in the plug somewhere. Less than 6 months old. Still better than the Fluke pipe clamp though.

Its a near 50/50 blend. You can top off without recovering. I have done this numerous times without any issues. Some of the other blends you might can get by with but if its not 50/50 I wouldn't...

No it is defined purpose.

Southeastern Cooler is a good one. Americooler is also a good one.

I keep paper invoices in the truck but only use them when requested. Most of the time my customers are happy with me emailing it or snail mailing it to them after the fact. If I write a paper invoice...

I have a friend of mine that subs some residential install work for me that is looking for something more regular. He lives in Molena. Are you still looking?

I don't care for my master cool. It hasn't held up like I expected. The yellow jacket is a much better product.

X5. I really like mine. I can't tell how much I've saved in fittings and sil-fos. To me this is a must have tool.

Water cooled is the only solution. You could rig up a lawn sprinkler spraying on the outdoor coil as a test. Saw that one time on a call. Stacked coil completely blocked.

You should look at trutechtools.com. They have kits made up with everything and I believe you can get a discount from being a pro member.

I have a CPS 6 cfm and it works good. I also have a yj super evac 6. Both work great but I usually go for the CPS first.

I had one Friday I just took the tube off at the gas valve and used compressed air from a can to blow it out. Worked great.

Caddy fasteners make a wide assortment of spring type clamps.

Just make it its own zone with a cool only stat to the board and that damper going to the corresponding zone.

I looked at one from supco. I think for the money it is the way to go. Just looking for opinions

Anybody have any ideas or suggestions on these? I would mainly use it to check power usage in homes and businesses. Mostly single phase.

If it is on a Copeland compressor Copeland makes an electrical handbook for all of their motors and units. You can get one at most supply houses. I highly suggest it. I can't count how many times its...

Quick books. I am a one man show and the money is decent. I am trying to grow my customer base.

When I do this I prefer a txv. It makes the job faster and easier with little guess work. I've done about 4 in the last month and they work like a top.

If the unit is out of warranty I say use 407c. If its still under warranty use 22. Sad to have to quote changing out a system that is only 4 or 5 years old. I did see 407 outdoor units at United...

I keep the Mapp & oxygen set from home depot in my pickup as a backup. Can't count how many times it has saved my butt at 2 AM.

Much appreciated!!! You guys don't get credit enough for the work y'all do. I do appreciate having a place to share ideas and help each other out. Thanks again Lusker!!

I read a thread one time saying it was going to happen. Im just curious as to when. My droid doesn't work quite as fast when going through the full site.

They should have instructions inside the cover. If you have the model number you can try and look up the manual. You can always check super heat sub cool and amp draw of compressor.

I have seen several new units come overcharged. I personally like to check them to verify.

If it is a heat pump there are charging procedures for winter. I do like to come back early spring and do a system cleaning and inspection and check the charge. Its something I do for every system I...

I would say put a 16" return on it assuming that the supply is correct. I have come to find that over sizing the return is better. Better for noise and better just to CYA with it not getting enough...

Ok guys the update is...yesterday I went and pulled the suction off and capped it. I put a service port on the suction intake of the compressor. The compressor would pull down to a vacuum but would...
