I will be purchasing a vacuum guage and was wondering which would be best. I am looking at the Supco VG64 the Fieldpiece SVG2 or the Yellow Jacket 69080. Any recommendations?

Thank you I'll check them both out.

I am considering purchasing software to do Manual J calculations. Is anybody using software that they would recommend?

Yep, absolutely call them back. It should not be doing that and if it continues could severely damage your comprssor. Most likely a problem within the electrical/start system.

Would not do it. It's not designed for that.

In answer to your question yes the system can generally be flushed, cleaned and pressure checked as long as there are not larger particles, parts lodged somewhere within the system. It can also have...

I can only guess that the system was sized properly and prior to the additions of the garage and screened in porch. Those two locations may very well be poorly insulated and after adding them to the...

Generally sizes can be determined through the model number. Somewhere in the middle or at the end two digits represent unit size. With your model number I would interpret it to indicate about a 2.5...

With your description it makes you wonder if he even knows what he is doing. If he is releasing gas into the air I would run away not walk that could become a serious problem. You should look for...

R22 is authorized to be sold until 2020 so it's going to be around. The EPA intent was to begin equipment phase out of R22 products after 2010 but due to a loop hole, without going into to much info...

Something is causing your compressors to fail, if in fact they have. I would get a second opinion, find out why they failed and repair it. It's only two years old it shouldn't require a complete...

The web site says it is not recommended for systems under 100 tons. I'd be using it primarily for residential. Thanks for the info.

I am looking to purchase a Fieldpiece SVG2 vacuum gauge and am wondering what opinions there are out there about this unit. Would you recommend the Fieldpiece unit or another brand?

I would suggest you get a second opinion. At ten years old you should have some life left in the unit. The compressor might be at the edge of warranty not sure. Looks like you are doing your...

It is somewhat labor intensive as the system has to be vacuumed down, brazed connections disconnected and rebrazed and recharged. Not really that big of a deal, I agree with Diceman I would probably...

What do you mean "have" a residential evaporator coil? What is your intent with this? Based on the question if you plan on personnaly installing it you better get some help because it doesn't sound...

I'm just a little currious, your post says you are looking to purchase, my question is how do you plan on making a purchase without the proper certifications? Most suppliers I know will not sell to...

Sounds like you have some sort of a problem going on with the system. How insulated and sealed is the attic? I would think you have more than adequate capacity, if anything I would think is is a...

I have always been a pretty good do it yourselfer. Studied construction is high school and have built homes and garages. My plan as a youth was to get into the trades but I took a different path...

I ment to say dry bulb issue.

Thanks, I am anxious to receive and use mine. I'll watch for an answer on your possible wet bulb issue.

3 ton unit for 2400 square feet in CT. Yes that would be plenty big enough my guess is that it is too big. I agree a manual J calculation for proper size should be done to determine if you do in...

Just wondering if it is properly sized. With your temp set at 73 I assume it reaches that point and if it still feels "sticky" it may still have high humidity in the air. Is it possible that your...

Dr. Phil: How do you like that Fieldpiece? I just ordered one and am waiting on its arrival and wonder how well it will performs.

I agree. If you work on that thing and he installs it then a fire breaks out guess who he is going to go after? I would avoid it.
