The other way I find gpm is
GPM=Tonnage*24/delta T
I just calculated above formula with machine operating one comp one circuit only close to fully loaded 87.5 tons? If that’s correct I got 210gpm...

Thanks I see what you’re saying my delta T shouldnt be so high with it at a partial load and I agree. I thought the best way to find GPM was to read deltaP off the evap barrel in ft of head and...

The iom chart says with my ft of head deltaP across the barrel is 900 gpm and with my 10* delta T on the water I thought flow was good

When I'm by myself I attach my pipe clamp thermometer right there before txv. Then heat it up and ice water it. you should see temp go up and down if txv is opening and closing

Oh thank God it's not about ME I had a red dot on my ass I was so ashamed i didnt leave the house for weeks glad I'm in the clear now. Hahaha PC people need hobbies so they don't have to bi*ch about...

If the metering device is a TXV then you charge according to SC not SH as units stats it wants a 10-11 SC. Keep in mind with no heat load in the house and low ambient your not going to see ideal...

Do you have a fresh air intake, it could be stuck on

Taking before and after readings on PM can help show customers the increase in performance and efficiency.

I did all that stop bein a di** and read my post

Ducts looked clear didn't see any obstructions I played with fan speed and removed filter. The best I could do was get it to run a little longer before limit trip. I'll try to crack the door some...

410a typo fat fingers

A customer paying excessive electric bills for one and two its harder on the equipment. Of course my previous company had a similar view just pass the extra energy cost to the H/O. Mo99 Is a joke...

Be prepared to explain to the H/O that there unit will run night and day to satisfy t-stat. Thats been my experience with 99 your better off changing unit out to 4150a or stick with the 22
