Are thermostat mercury switch tubes supposed to be exactly aligned?
Merry Christmas!
I have an older Trane system with a mechanical thermostat that uses two mercury switches mounted to the bi-metal temp-sensing coil.
One of the mercury tubes is just a hair off from parallel with the other so what will happen is when it heats to a certain point the heating element turns off but the air handler will keep running because there's still contact with the mercury switch.
Are they supposed to be like this or are both mercury tubes supposed to be exactly aligned so they always complete or break the circuit at the same time?
Merry Christmas to you! I can't answer your question regarding the thermostat alignment. However, I wanted to mention that it's normal for the air handler/blower to run for a period of time after the thermostat has reached its set point. It would be very inefficient if it didn't. When the thermostat stops calling for heat, there is still a lot of heat left in the heat exchanger. The blower runs until the heat exchanger temperature drops to a low level. Many thermostats have an "anticipator" setting. This slightly heats the thermostat so that it turns off slightly before the set point is reached. When properly set, the anticipator prevents the heating system from overshooting the set point. The anticipator essentially gives you fine control over the cycle length.
Hi everyone.
I have a thru-the-wall AC unit that it's making the living room very drafty in the winter.
So I want to place a small shed on the exterior to cover it permanently, and the idea is that I'll have vents on the shed that I can open in the summer.
I've been googling for hours, including reading manuals, and I couldn't find the answer to this question:
Is it safe to cover it?
Thank you, and Merry Christmas!
Guido.
Hey Guys,
Hoping for some assistance here. I just moved into a new apartment and am having a tough time dealing with the Moist, Humid, Water odor coming from the AC unit. At the first the issue appeared to be mold, but that does not seem to be the case.
So far steps taken:
1) Unit has had its inside fins cleaned. twice.
2) Ducts have been cleaned
3) Ozone Machine was brought in.
None of the above has fixed the issue. The problem i have is i cant tell what the cause of the odor is, I tried adding a MERV13 filter to it, but that doesn't do much as the odor is coming out of the AC itself.
The apartment management company has called the AC Contractors to come out and look at the system and they say there are no leaks, and that the odor is not mold.
So what should i look at next? Do i just buy a dehumidifier? Spray the the inside fins down with Odo Ban? I am not sure what the best course of action is moving forward. Or if i am just being overly sensitive?
Thanks,
Robert
