Depending on your specific equipment setup, you may have a variable speed condenser fan, variable speed compressor, or both. With a variable speed compressor and condenser, the system would ideally maintain stable superheat and suction pressure (effectively controlled by the Siemens superheat controller) and would maintain a stable temperature differential ...

Former HVAC controls guy here - so I understand this stuff a little bit. Disclaimer: It has been about 10 years since I worked on this stuff so my memory is a bit rusty. The Siemens module is controlling the amount of evaporator superheat by means of modulating the TXV (thermostatic expasnion valve). So the mechanic is partially correct, it does make the ...

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'm in Michigan and we get harsh winters and salt our roads. Salty roads and ice get on our cars, and this combination is really harsh on our metal parts of our cars. Salty humidity is also very harsh on any metal parts, even galvanized steel. Now galvanized steel in the US has improved in the past 20 years, but it is not impervious to salt water. That ...

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 ...

If you're not allowed window units (not even stuck mostly inside?) but could get away with an exhaust vent in the window: Portable Server Room Air Conditioners: -uptime4u.com Depending on the kind you get, you're going to have to empty it occasionally or find a way to drain it. It should have a standard filter rack that will work to some degree. Or ...

My wife is asthmatic and has strong allergic reactions to dust, mold and dust mites, so we deal with this very condition. There are some 'portable' air conditioners that draw air from inside the room and cool it, while also cooling the room by blowing the heated air outside. These come with rudimentary filters, but also have the added benefit of creating a ...

Check the CFM rating of your blower unit against the square footage of your home, and the capacity of the furnace/AC units. It could be too high and in need of adjustment or replacement with a lower CFM unit (contact an HVAC pro if you aren't confident in making this assessment yourself.) Also, check that you have the right air filter in place ahead of the ...
