Something that meets or slightly exceeds the 35 in-lb rating, and matches the 24V spec (though you could check if your system is using AC or DC, and just get one to match your system rather than an AC/DC version.) I suppose the time should fall in the general range of this one's 80-110 seconds as well, so vents are not slamming open and closed, but I ...

You could try having the ducts Aerosol Duct Sealed. An expensive process not intended for it's acoustical value, but I assume it would offer some. Reduce noise from forced air furnace. -More related to unit noise then from people, but you still have two basic options: baffles or insulation. Other options: move the TV so it doesn't shoot at the registers; ...

The previous person answering your question does not have a sufficient understanding of HVAC systems. For the past fifteen years, I have been working on such systems five days a week. I have learned a few things about such systems. As long as you have more than one return in your home, capping one return will not damage your system in any way. I set up ...

I found this statement from the manufacture (Fasco) of my old and replacement part: The blower is designed to produce a certain amount of air-flow measured in CFM (cubic feet per minute). The airflow in some furnaces is needed to create a specific amount of vacuum at the vacuum tap mentioned above. If the replacement blower is not the exact one ...

R in general R, Rh, and Rc are all the same, but not. In general terms, the R terminal is where you connect the signal voltage source. In low voltage controlled systems, there will be a step down transformer that provides the power to the control circuitry. One of the legs from the secondary of the transformer will be connected to the R terminal, which ...

You want your vent venting to air as much as possible. If you are cooling/heating your walls/floors/ceiling this is much more inefficient than doing the same to the room. Think about it this way... Let's say 25% of the heat is absorbed by the wall. Do you think the wall will heat up the room to reflect that 25%? Maybe reflecting 1/5 of that if that. ...

What a great question. I love questions that hit the sweet spot between a textbook, and the real world. Textbook Physics says that you save energy by pointing the vent to blow to the room. Real world physics says that blowing toward you better when the A/C is on, and to the wall when heating. Personal preference is, of course, a personal decision. In ...

I will give this a try. Physics says that water can not make steam, at sea level pressure under 212 degrees F. It is also why steam pipes and automobile systems are under pressure, you can hold more heat, when water is under pressure and not have it boil. Pressure cookers cook food faster for the same reason. The only way to make steam, from water, at ...

This first thing to try is removing the thermostat and shorting the R and G wires. Usually, these are the red and green wires. This should start up the fan in the blower. If that works, try shorting R and Y (usually yellow). This should start up the fan in the blower, and the AC compressor. If all of this happens immediately upon shorting the wires together, ...
