How to Install Room-By-Room Zoning in an HVAC System | Ask This Old House

Guy would make a killing if he would sell this off to NEST to integrate with their learning thermostats and temp sensors.

[alir.]

Wow! They showed an entire video without saying the name of the company??

[rodgraff]

One of the main issues all zoning systems have to overcome is trying to vary the airflow volume, when most residential HVAC equipment is constant volume. A true variable volume system has equipment designed to run on a wide range of airflow. There is high end residential equipment that is variable volume, with modulating heating and cooling. These high end systems, with variable capacity work well with zoning systems.

Their website says $5000 for this system. What a joke

[cg]

Really neat idea. The registers are a little ugly. Would like to see something that could take the existing registers, and mount under/OR replace the damper. Otherwise really neat.

[shadowbanned]

1 prob...no integration with furnace or t- stat. If register says need heat. Who tells t stat to fire furnace? Did I miss something?

[nellAyaR]

This videos should be titled, "how to piss off your hvac service tech & kill your compressor"

[tenthdimension]

$2200 for a 1500sqft house. Are you out of your mind? No WAY I'm paying that much for this cheesy plastic junk!!!

[jackoneill]

sensors used in missles defence., . lol i love how they upsale a 30 cent sensor.. military sensors are thousands of dollars redundancy your using a freaking arduino temp and moisture sensor 99cents on ebay dont lie bro... dont push a product that clearly anyone can do

[lin]

When the main thermostat is not calling for cooling/heating, how does the register or hub energize the cooling/heating for the other zones?

[davejoseph]

I don't see this as too thrilling. If you can adjust the registers to solve the problem then you don't actually have a problem.

[juant]

but what motor should the furnace have.? regular psc motor?? would closing registers over pressurize duct work? what about a closed register getting to cold and creating humidity problems? come on people don't just buy products without asking your contractor

[mikecsolak]

Sorry people: They are having a lot of trouble with these. defective dampers Need air bypasses etc. I really wanted to try these in my business but decided to wait until I heard of any problems. glad I waited. I was very leary when I heard they needed no bypass. Well, it sounds like they do! lol

[Nick_Lavigne]

You should make the outlet sensors so they screw on the the wall plate at the center screw. It will stop it from coming off when devices are unplugged.

[davidperry]

It would be nice if you could hardwire it with a transformer instead of using batteries.

[knockitofff]

i can hear the whistling in the room I'm sitting in now when the other rooms choke off LOL

[phatan]

What’s the name of this product. I see no names mentioned.

[seanmathews]

Attention public. You don't need zoning. It causes more problems than any benefits you might get from. Been doing HVAC for more than 30 years and have never seen a zoning system that really worked properly. You are far better off with one thermostat controlling the whole house.

[keereh]

As a hvac technician I won’t pick this option. This is not a good solution to get comfort.

[blueribb]

Where is this manufactured ? What is the warranty ?
