I have a Ruud high effecency Achiver 90 Plus, it comes on and runs for 10 minutes and then shuts down for 5 then starts all over again. We have a old farm house about 2300 sqft. We keep the thermostat set at 67. I changed it out thinking it was bad but it still cycled alot. We went through 360 gal of propaine in 4 weeks with this furnace anyone have any advice?
I do not have any HAVC experience so simple terms would be appriceated.
