will my generator run my central ac ?
I have a generator that is 5550 watt and peak 8550 it seems to run my whole hose when I need it, lights, refridge etc
Is it ok to run my central ac ?? AC company said no problem.
I would be real careful....many times the electrical sign wave isnt even and can damage circuitry.

Paci, what does that mean ??? Also, I have run my Rheem gas furnace on it and my refridgerators with no problems, isnt this what they are for ????

If you're already running lights and the refrigerator, a 5550 watt generator isn't capable of running even a small 2-ton central A/C. They simply don't have the surge power to start the compressor. They're pretty much maxed out with a 5-6000 Btu window unit.
Here's a good read on selecting a standby generator to handle your A/C:
I think my ac unit is 1-1/2 ton ?? Its a small ranch house. I have 1 refridg. I have had this run my 80 gallon elect water heater before no problem ????
How would I know for sure ?? If I tried it it would bog right down if it wasnt enough ?
It ran my NG furnace ok , should it have ??
You're on thin ice ... Water Heater, probably it's a resistive load.
NG Furnace, maybe - maybe not ... repair could be $$$.
You need 12 - 15 kw to reliably run an a/c and there's no guarantee attached. You wreck it - you own it.
Do not attempt vast projects with
half vast experience and ideas.
when I do the water heater I shut everything else off, the A/C chart beow said starting power needed fr 2 ton unit was 5k watts after 3 seconds that drops off a lot. Mine peaks or surges at over 8k watts !
You dont think I should use it to run the furnace either ??? What the heck good is it then
What the heck good is it then?
so you can fire up your puter and join us here.
looking at the online sizing chart it says mine is PLEANTY big enought ot run my furnace and refridge and lights, you guys dont think so ?? Again it has 8550 surge ! I have run the furnace before on it with the refridge and small freezer with zero problems.
If it couldnt handle the start wouldnt it throw the breaker on the generator ?
