Need to replace old Fraser-Johnston a/c unit in Los Angeles
My a/c broke last week and the hvac specialist says my Fraser-Johnston condensing unit is over 40 years old. I've only been in the house 16 years, so I can't verify it's age.
It's a single story ranch-style house with 1430 sqft of living space with crawl space under house and attic above. It's an oven in here.
The 1993 (Made in the USA) Rheem Criterion Gas Furnace in the attic looks new. It's a model RGPH-07NAMGR, 75k BTU, 21.97 kW, 3/4 HP. The only repair that I've done to this gas furnace is replace the electronic ignitor a couple of times. It was an easy job that I did myself by reading the forum.
Fraser-Johnston Model HDEC-F042SA, R-22
Evaporator Model G(M)BUA048
HVAC specialist says to replace this Fraser-Johnston outside condensing unit and its electrical wiring. He suspects that everything in the attic like the furnace, ducts, etc. was done new in 1993, but somehow kept the old Fraser-Johnston condensing unit on the outside.
He's also not recommending to change the pipes (lineset?) that go from the outside condensing unit up to the attic.
Does this recommendation sound reasonable? I don't have quote since I don't have the details of what to replace with.
Any help is appreciated.
