TIA for any help.
Geez, there's a ton of spam in this group, sorry for the pun...
Well, I have a 8 year old house with a unit that was described as a builders grade 3 ton Trane by the service tech that was at the house today. The house has been getting overpowered by the heat in the afternoon and I called my regular guy who does the PMs to check it.
He says I have high head pressure and was 3 pounds low of freon.
My options were.
1- Evacuate, clean and refill. 2- Leak detection 3- Just add freon, hope it lasts the season. 4- Replace the unit.He says he wouldn't waste money on #1 because the unit is 8 years old and it's a builders grade. He says he's seen a lot of them go after 8 -12 years. Leak detection would probably chase the leak to the evaporator, which again, he wouldn't replace because I've got a 10 SEER unit and if I replaced it with another 10 SEER unit that would screw me if the condenser outside went. I asked him to add the freon and the house immediately cooled down and even though it was 96 degrees today, the house stayed comfortable. I'm happy but I know it won't last. He said he was able to get almost a full charge of freon in the unit without the pressure getting way high.
He explained the high pressure is being caused by a dirty control valve between HS/LS. He says evacuating, cleaning and refilling may help or hurt and then you still have the leak...
Question is. Is 8 years enough for this "builders grade" 3 ton Train unit or should I consider getting the system cleaned, recharged and find the leak. If the leak is in the evaporator, should I then consider replacing the whole shebang.
Thanks Much.
