You know it's also hard to diagnose over a computer
I would rethink your design a little. Maybe it would work better if you used a bag type filtering system that collects the dust on the outlet side and a cheap filter on the inlet side to catch the...
I understand where your coming from now. As far as proving the problem on the electrical side is from age verses damage from say, a surge or something, that would be difficult. The compressor,...
You would have to make sure you can even get enough loop in there to handle the load first. Then you have the concrete issue on heat transfer.
Not a good idea. If it had fresh water running through it all the time it would work. Then you could go open loop.
Main trunk should be reduced at certain intervals along the way to create proper backflow for even cfm to all supply outlets. this is laymans terms but, there is alot more to it.
2- ton is 18x8 one way. 3-ton is 8x25 one way.
Just a thought, most systems aren't designed for extreme weather. Reading into your problem and the age of the system, it may be time for an upgrade anyway. Personally I would want something more...
With all this information I would call back the technician and have him check more thoroughly.
I have a gut feeling that it is a 2-stage system and low stage is not wired, hence a lighter load on the house at night calls for low.
You wouldn't happen to have a 2-stage system would you?
If it's a programmable stat maybe it still has to be programmed? Just a thought.
Could be the system you have is way oversized. That's why it's important to have everything checked!
I don't know about them, but I wouldn't want to lose a customer over something so petty!
Sounds like a txv not operating properly (opening and closing as needed) or wrong size piston at evaporator coil. If it is an electric air handler you might make sure the heater is not running in...
Have you given any thought on Geo- thermal?
Variable speed helps alot wiht a 2 stage system. You get more run time in low speed to help with humidity levels, but the system must be sized properly. True Steam humidifiers really work well also...
If there is room to install a nice transition fitting between the existing furnace and coil, go for the 21 wide. If not you might consider changing it all now. Later prices will rise.
Make sure you didn't get confused on low voltage. It does happen.
The 2 filters are fine, They will help keep the return ducts clean. Only thing questionable would be if they cause too much restriction. Service tech should be able to check that for you.
I remember when Waterfurnace first came onto the market. In fact I still have the first books from seminars I attended. I have installed every system they came out with and have worked on several...
Check house insulation
My first guess would be a return air could be knocked off in the attic or system is sucking hot air from somewhere.
Did you say the geo is in an upstairs closet ?????
It sounds like what you are describing is a bad connection on the high voltage to the outdoor unit. All it takes is one side to drop out
