During heating season, it may not run long enough to warm up the space evenly. During cooling season, it may not run long enough to pull out humidity properly. No benefit.

The OP wants zoning to "save money" by turning off the HVAC to "unused" parts of the house. It doesn't work that way. The equipment, with rare exception, does not modulate capacity. The desire to change temperature in an area is an unusual example for residential HVAC zoning. The common...

It's not, because you do not know how the equipment works. A typical residential system cannot modulate output. If there is a 100,000 btu furnace and 3 ton air conditioner, the equipment is still operating at full capacity, even if 1/2 of the ducting is "shut off". The dump zone recirculates...

The adaptive cruise doesn't work on the 2 vehicles I have had with it, if the radar sensor is covered with snow. The VW sensor was down low and the Honda has it behind the grille emblem. Neither have figured out how to keep the sensor warm enough to keep snow/slush from sticking to it. I did...

Pretty sure that it's radar based. It is on a prior VW and current Honda.

Thanks for this.

Zoning is for comfort- it will absolutely NEVER save any money. Comfort, if it is installed properly. I have not seen many zoned systems, and of those, none of them worked properly. Most residential equipment can't modulate capacity, certainly not the lower priced stuff that is mentioned in...

Woo hoo. An update.

Last I looked, their vacuum stuff was sorted by itself, or tagged on evacuation product pages.

Did you go to the site I recommended and watch their videos? They will sell tools to anyone with a credit card. I do not recommend buying the tools unless you know how to use them. But, whatever.

They won't be, maybe a house in California could be an exception.

I can guarantee that damn near every residential duct system installed prior to the adoption of the 2012 energy codes has a minimum of 20% leakage. I have personally tested 30% leakage. Unfortunately, testing methods and reports can be falsified. "Sealed ductwork" does not mean that the...

A vacuum pump can be left running for hours. Connect the micron gauge to the port on the pump and turn it on. The pump should reach under 100 quickly if the pump/oil is good. Vacuum is isolated with core removal tools and vacuum rated hoses. The valve on the pump is no good for this. Watch...

If the micron gauge was attached directly to the pump, and if the micron gauge is a good one, it should read below 100 microns very quickly, even down to 20 microns can be attainable. I would run it with the valve closed for 30 minutes or so, change the oil, and check it again. Old oil or...

Yes. I use Amsoil synthetic compressor oil in mine.

If there's enough moisture, you can see it 😁

Lots of bad reviews on the Milwaukee version. Personally own a Ridgid, nothing wrong with it, and certainly wouldn't buy the Milwaukee to "try it out".

I honestly had no idea that so many people would need this.

I have a Cox "extra thrust" caulk gun, made in England (IIRC) that is over 20 years old. The design has since been copied and knockoffs are available at the box stores. Also have a Tajima that works nicely.

Bypass the thermostat and jumper out "fan", "heat" and "ac" and see if the fan motor acts up. Turn off the AC circuit breaker or disconnect so the condenser doesn't run.
