The gauge will not be damaged by exposure to positive pressure when releasing the refrigerant, so the best practice is to leave the micron gauge attached until it reaches a positive pressure reading....

The yellow jacket gauge is made by and essentially the same as BluVac, one of the best gauges on the market in my opinion. The reason it is reading differently is because of its greater resolution. I...

What C02 sensor are you using? Does the fresh air come in via the dehumidifier or separately?

I can't speak for these ladders personally since I don't own one, but a lot of local roofers seem to use there around here. I have used one once to get on a roof and it seemed relatively sturdy,...

My G5 runs several time a week or more for me and has never even sneezed. It has the fastest recovery time of anything I have ever seen or used, and I also use it routinely to push refrigerant into a...

Very nice and clean looking.

If it is all one circuit, maybe something like this?

Try Duluth Flex pants from Duluth trading. Good fit, hold up well, comfortable in summer, and have lots of pockets for small tools. Like you, I wear a lot of hats, and these work for me.

Another item to check would be if there are any splices in the control wiring. Communicating systems, including the Carrier infinity, do not do well with splicing because of the interference it can...

Ask for what you want and have the contractor supply. I would have no problem with that with any of my clients, tho as BaldLoonie noted, I would tell you if I felt one of your requested options was a...

It has not ever made it hard(er) for me. I have always used dykes to sheer them off at the nut with no issues.

Also, I check rotation on these types of motors and wire accordingly. Then, I sleeve...

Something else is wrong. I would look for a more experienced tech or company to resolve this for you.

Permanent full-time year around position. Looking for 5+ years experience in residential and light commercial. Home performance testing knowledge and experience a plus. Pay is based on ability and...

Fluke 376. Backup is a fluke 902, and I also carry a fluke 116 and a fieldpiece hs36 for redundancy.

I would recommend a stand alone micron gauge for the reasons already mentioned. I prefer the blue vac, but there are many good options. Hope that helps you.

Iphone and IPad. I have used android phones and tablets for both personal and work application and did not care for them.

That must be why I prefer Makita. I always wondered about that.

Nailed it. This is off of Jefferson in Oak Cliff.

With all those errors, someone needs to re-evaluate everything for you. It is like the fuel light in the truck; you can ignore it for awhile, but eventually it ends badly.

You may be smelling the...

We do this with all new hires, and it is invaluable. I would not take it as disrespect for you and your experience sir, but rather an opportunity. With your time in the field, the tech you ride with...

Understood. I would want a 16" connection too. Also, I would want to be sure that the grille sizing is capable of conveying the volume needed. Basic formula to check this would be width X length X 2....

You may want to source a different contractor who is qualified and able to perform these calculations and see if the equipment and duct is really the right size.

I agree that the undersized...

Ask your contractor for a copy of the Manual J load calculation and Manual D duct design he completed for the new system and post them here. He did complete these, right?

Gerber Diesel Black Oxide. I got a little adapter for it that converts the Philips driver tip to a chuck holder. That and a 1/4", 5/16", and 3/8" in my pocket with a penlight and I'm good to go. I am...

Sorry guys let me clarify. The RTU "install" was permanent, as was the duct job. Apparently, we were called in for maintenance after they started having folks complain about the smell when the unit...

They wanted to know what it would take to "improve the duct system". Some unspecified person told the owner that the duct work "might not be quite right".

Possibly, but the gas line running across the middle of the hole makes me think no. Inside is tight as it is between floors, but it looked like it originally was fed by split system AHUs down in the...

This was my first time on the site. Manager of the building told me it has been this way for about a year. Some of the flex has standing water inside it.

If you smell gas, then I would infer you have a leak somewhere. The gas company or a differing hvac company should be able to find it for you.

My advice on equipment, when all of the considered equipment is similar, is to pick what you like best. The reason for this is that most of these units in that SEER class are very similar,...

I work in the DFW area and have no issue with Trane. I think anyone in the industry could potentially make a case one way or another, depending on their personal experience and preference. Side note...

The manual for the product that you posted recommends less than 100' of equivalent duct length. If you are properly transitioning the 3-1/4x12 to 6", and it it under 100' total equivalent length, it...

Regarding make up air: if you take 600 CFM out of a space, then 600 CFM will have to enter into that same space from somewhere else. Otherwise the vent hood would pull the home into a vacuum, right?...

Where/how does the make up air enter the building envelope?

Good choices; congrats on your purchase. Been there nailed it; there is very little ROI in a VS blower. That said, comfort is a valid consideration, along with reduced noise. It is equatable with the...

It is only up/down on Mitsubishi. Side to side is adjustable, but manually. The iSee sensor is on the hyper heat model, so if you are in a heating dominate climate, that is the way to go. For cooling...

Yes, I can.

10-4. Does that include the LC or just the small bags?

How much do you want for them? I have the LC now, but would consider one or more of the smaller meter bags.

Sure, just put a house and a VCRT inline with the low side.

I have Malco and Dewalt. I prefer the Malco. I have a 1/4" that still holds metal zip screws great, and I have had it for years.

I had a Carrier with the same over-current drive error this summer. After the second visit, we brought in the factory tech/rep to recommission the unit. They never told me what they changed,...

You are correct that there are many methods you could employ to get the thermostat installed. My advice is to ask a couple of friends neighbors for a HVAC company referral. Pick one and call them...

The mini is very convenient and easy to carry. I can get one in the side pocket of my cargo pants. PDF files open no problem for me and I have hundreds of them in iBooks and Dropbox. Since I moved to...

My hand tools always go with me when I travel. My in laws and grand parents always seem to have a list of little things they need help with when I visit, and I like to always help them out and have...

I have the 6+ and my experiences track with the above opinions.
-Seems obscenely large for the first few days, then you are sold on the product.
-Much easier to read on, and show clients...

So it is time to retire the F250 due to high mileage, and need for more storage. I have ordered a 2014 Sprinter / Frightliner standard roof 144" WB van to replace it.

I have been looking for a...
