I had a 3.5 ton Lennox AC that the outside unit failed (r22)

I had a 3.5 ton Lennox AC that the outside unit failed (r22) the air handler is it a store that would involve a lot of carpentry work to replace. I found a brand new 3.5 ton Ruud to replace the failed outside unit with however did not realize the Ruud had a TX valve and so does the Lennox indoor unit. Here is the question can I remove the TX valve from the indoor unit or should I replace the whole A coil? Thanks Jay

I recently purchased a Lennox AC unit. After it shuts off it

I recently purchased a Lennox AC unit. After it shuts off it goes through a series of sounds that drones on like an airplane landing. The AC company says everything is fine, but the noise alone is very annoying going on for 15 seconds after it shuts off. It seems that the manager that finally came was able to adjust it to lessen the volume of the noise, but it still occurs. The only explanation I got was its probably my metal ductwork loosening and causing the sound and that they don't know why it makes that sound, but everything is fine. Help! I paid $12,000 for the system and I feel like it's defective. I've lived here 20 years and had a Trane and Carrier that never made these sounds. Thank you.

I have 2.5 ton residential split unit, it said to be 400cfm

I have 2.5 ton residential split unit, it said to be 400cfm per ton , so it will be suppling 1000 cfm, when installing new duct work, do i need to have all supply vent total equal to 1000 cfm? What i am trying to do is because there is three rooms total 800 sqft 2nd floor. The air handler is far away from two of the rooms i tried to push a stronger air flow to the rooms.I am currently using two 10 inch flex duct from the plenum and use a Y to split two 8" flex ducts. Can i just leave it like this? Because one 10inches supply only 300 cfm, so i only have 600 cfm supplying, would this choke the system?

I I'm installing a Honeywell rthl2510 thermostat on my heat

I I'm installing a Honeywell rthl2510 thermostat on my heat pump system. I have the wiring completed and started the system. The cool on indicator is on though the system does not operate. I noticed something in the installation instructions about a Y1, W1 & W2 needing technician service. My old system has a Y, a W1 jumpered to the Y and a W2. There was a jumper from the W2 to an E terminal on old thermostat. All that to say does this system qualify as a Y1, W1 & W2 system that needs special wiring? Or have I just not wired something correctly? For reference, I have the W2 wired to the W/Aux terminal

I'm purchasing a new top of the line Trane AC system with

I'm purchasing a new top of the line Trane AC system with the new XLV20i compressor that supports variable compression between 20% and 100% and a matching Hyperion XL variable speed fan air handler. These are communicating units. What I'm trying to understand is what kind of thermostat is required to allow these units to take full advantage of their advanced features. What exactly is meant by "communicating"? Can any thermostat be used or does the thermostat need to support the variable capacity compressor and air handler?
