This is what the HVAC specialist said that I need done

This is what the HVAC specialist said that I need done besides the new central A/CDo you agree that considering what he says this is needed? I amTalking about the copper wire and duct workThere is currently a 3 ton system from 1994 at the house. It will need just a few things in order to make the system work at its peak performance.The system will need larger sized copper lines to insure that the refrigerant from the condensing uint to the air handler can handle the higher pressures that the new systems operate at without causing extra stress on the equipment (Current copper size is 3/4” x 5/15” and it needs to be 7/8” x 3/8” copper).The other thing that it will need to make the system be as efficient as posable, and reduce a sweating air handler, is to enlarge the return duct and supply duct from the air handler. Right now there is roughly 750 cfm's on both the supply side and return side. A 3-ton system should be moving around 1200 cfm's on both sides. By enlarging the ductwork, there will also be less stress on your coils, blower motor, and compressor.

I have a carrier gas heater and the "pipe" coming out of it

Hi, I have a carrier gas heater and the "pipe" coming out of it is very hot. It kinda burned my finger. It is very cold here in san francisco and I wonder if the fact we have it turned up to 70 may be the issue-is it normal for the pipe to be that hot-the heater does appear to be working...JA: How long has this been going on? And how severe is the problem?Customer: I just discovered it now. Everything is working it is just a very hot pipeJA: Do you plan on doing the work yourself?Customer: no-I called a heating company and left a message but I wanted someone to tell me if this is normal for the pipe to be so hotJA: Anything else we should know to help you best?Customer: I think that is all

Why does our Carrier Weather maker 9200 gas furnace

Why does our Carrier Weather maker 9200 gas furnace converted to propane (at church) will work fine except it will shut off and on. If it stays on until the thermostat shuts it off it will heat the building fine. But most of the time it will shut off for a few minutes and come back on for a few minutes never getting the room temperature high enough for the thermostat to shut the furnace off. Has been doing this for years.

I have a Ruud 90 plus deluxe drum furnace that initially

I have a Ruud 90 plus deluxe drum furnace that initially starts fine everytime, but when the main blower comes on the gas valve shuts off. The flame seems to flutter or lift and the flame is somewhat sooty not clean blue but yellow when blower starts the flame flutters then the gas valve shuts off.JA: Did you check the furnace's filters?Customer: yes they are cleanJA: Do you plan on doing the work yourself?Customer: yesJA: Anything else we should know to help you best?Customer: after several tries, the furnace will eventually keep running, but never on the first try. the igniter always glows and gas always comes on initially. I checked the gas valve pressure with a digital manometer and it is at 3.50" w.c. incoming air not obstructed, the condensate drain is clear. I did notice the gas valve pressure did fluctuate quite a bit between 3.4-3.7" w.c. Could the gas valve be bad?
