How long has your AC run ?

Hey, thx everyone, great info.
I feel better now, not assuming its a ticking problem anymore.
I have rinsed it and filter changed it over the years.
I foamed it today, and saw results. Blowing colder still
Interestingly it stopped dripping condensation, pan may have debris clogging it. Will check.

Thanks again.

Mine is on a motorhome.
The date code shows 10/93 installed 02/94 on my RV. It's a Coleman TSR rotary. Still going strong, cools well and no leaks. Routine maintenance is the saving grace.

My 1993 Emmerson is still going strong. That's good because Emmerson doesn't make a RV AC anymore and I don't know how I would get a any parts. It sure works good though. My brothers new 5th wheel AC doesn't work as well as mine.

The AC in my 07 was still working fine when we traded it in a few years ago. I did have to clean out the condenser fins a couple of times.
I had a 93 Award TT and the AC was working fine when we bought it. Right before our first trip I went to turn the AC on and it was warm. Thankfully my neighbor does commercial HVAC. He found a line that cracked from vibration. He repaired the crack. Installed a charge fitting, vacuumed and charged it and it worked fine for the 2 years we had it until we traded it in.

And because of that little find, I always test things 3-5 days before we leave.

Clean the filters, remove shroud on roof and clean the coils. You are way better off with that one than a new one.

1997 5er in sig still puts out cold air here in 100-110 degree heat. It did need a small charge in 2010 era but has been fine since.

The 1 on my tent trailer was installed in '95. Can't say it keeps trailer cool, it is a old tent after all, but on a 100* day the outlet temp is 40+ degrees colder than inlet

Our last 5er was a '04' we brought it in '10'. We fulltimed in it for 7 1/2 years. It was the original AC as the owner had been meticulous in his record keeping.

My 5th wheel is a 2002. I just replaced the aging unit last January.
