Depends. The foil mastic tape won't come off.

Unsealed ductwork and big gaping holes at the air filter connection likely helped with the early demise of this system that's not quite 10 years old. It isn't made to cool the attic...

I have one made by Thermal.

Not sure that guardrail will slow down, much less stop, a piece of heavy equipment... 🙃

Well, except for the first two iterations of the Digi Cool digital manifold, pretty much everything is now made in China. There's way more choices now, compared to when the Digi Cool came out, but the Digi Cool was made to be just about bombproof. I recall many, many issues with the early Testo...

Pretty sure one can get Testo for under 500.

Almost no one used to pull a vacuum, much less use a micron gauge, "back in the day". I had a Thermal analog gauge, it was the only game in town. Now, Blue Vac is the standard. Theirs is still the best. Used to have a Cooper thermocouple box, used velcro to hold the sensors on. Used a PT...

The Little Giant ladder can be positioned so you can face a wall, and be right in front of the wall. Much safer than leaning a regular ladder against the wall- but there are regular A frame ladders that are made to be leaned against a wall, which is a fairly recent design. Little Giant used...

I bet someone ordered the wrong voltage 😁

It doesn't take much to stop a Trane... 🙃 You'll want hail guards. You'll want the economizer. If those have micro channel coils, do NOT use anything but plain water to clean them.

You are looking for something called a "Magic Pack". There are variations. Good luck with that. A mini split condenser on the roof and heads or ducted systems inside would be the most theft resistant solution, but roof access is needed. Those Bard units are likely serviced from outside and...

Darn. I was half expecting a thread on VW's... or Honda. 🙃

If there is an evacuation mode, you'll never pull it into a vacuum without opening the solenoids. The solenoids seal good enough for normal operation, but will leak refrigerant, or whatever they are holding back, under vacuum. I would strongly suggest going to Tru Tech tools and watching...

Some units have a specific reclaim and evacuation mode. If the proper procedure is not followed, there will be closed solenoids and trapped refrigerant or nitrogen.

Might have something to do with seatbelt enforcement. Some cargo vans have an option for colored seatbelts for easy driver compliance confirmation.

I prefer Markal over Sharpie. Not particularly impressed with Milwaukee markers.

The above is true of any welding class I have taken. Running a bead on a short and flat coupon, in your preferred position, is completely opposite from welding in the field. Moving from something flat to something round adds more difficulty. Then use your non dominant hand. There's no...

867-5309?

Just bought these. They work great.

If the room is closed and if the water heater is natural draft, it isn't a good idea without transfer openings.
