Iíve been tasked with a job of replacing a evaporator coil on a small split system at a site thatís a 6 hour round trip drive, which only gives me 2 hours and there is no overtime allowed. I was wondering what the average time would be to accomplish this.
I already know that Iím going to have to make a couple of trips and I definitely need to pressure check this overnight. The system was already evacuated and a new condenser was installed 3 years ago, but never started up because a problem was found in the evaporator during the vacuum test. The condenser was never opened up and it still has the original charge. Iím hoping that I donít have to replace the lines due to the time constraints and Iím concerned about the lines being rotten.
My plan is to change out the evaporator coil and pressure check it over night with nitrogen, which Iím pretty sure I can do this in less than 2 hours. And by leaving all my tools on site I donít have to clean up.
I'm hoping to finish the next day if all goes well. I donít know what it is, but it always seems to take a lot more time for the little stuff like vacuum testing, charging and final operation checks. There always is something left to do. Oh and then thereís the clean up. I liked it when I had an apprentice to pick up all my stuff as I was working.
Anyway this going to be the longest time I've ever spent on installing an evaporator.
