Currently have Armstrong Ultra III HVAC using LP. Last few years have had a sooting problem, I've always cleaned it myself w/a vac and air under pressure.
Well, the sooting problem has gotten worse and checked the flame and it was it being blown about and yellowish-orange. The bottom of the flame was a healthy blue.
Pressure is fine and not water coming in w/LP. Still, the gas is shut down as a precaution for CO
The system was installed by our contractor in 1993 and has been fairly reliable for a bottom-feeding system. Visual inspection on the exterior shows some rust at the seams and around a couple of screw holes. Burners look terrible even after 3 cleanings. I know there are a few tests to check for a cracked heat exchanger, but is there anything I can do/look for until the professionals arrive?
I'd rather not him have to tear the thing apart only to find it cracked and have to be replaced. My question is can I spot the crack(s) w/out getting soot and mess all over the living area?
2ndary Q: If the system has to be replaced-I'm thinking about just going ahead and spending (near)top dollar and getting an efficient Trane system.
We live in the heart of Dixie w/fairly mild winters and blazing summers
