I have an American Standard unit showing error 91
Had error code 91 on Trane XL19i thermostat. Heat season on duel fuel system. Repair tech said board is bad ($963) and transducer ($1000). Unit is 3 ton 12 years old. Does it make sense to repair or put in a new unit?

I have American Standard error code of 156. What do I do to correct?
american standard error of 156... on a car? If PO0156, thats an ODB2 sensor... possibly the second O2 sensor on your emission system. You can reset the code and see if within 100 miles it lights back up... Likely it will. You may have a burned out catalytic converter... or a bad O2 sensor... or a blown head gasket, or many other things. If that is the ONLY code I would go forward with the O2 sensor. Look it up on ebay, year, make and model of car. Typically if one o2 goes, the other will follow. It is symptomatic of the cat going out though. How many miles on the car? More than 150,000? Likely its the catalytic converter. They are a consumable in your car. It will affect your mileage significantly while the code is on, and typically if it is the o2 sensor itself that has gone bad ( between 30 and 100$ per) and the cat is ok, if you don't fix the o2 sensor, the cat will burn up (cost between 200 and 700, and a bunch to swap out) Get it checked out, you're looking at more bucks the longer you wait

American Standard Heat Pump thermostat stuck in "waiting" mode, but running, blowing room temperature air not as hot as it usually is.
Could be a number of things:
Could be as simple as having bad batteries in your thermostat “ if applicable” some thermostats do not have batteries.
Could have a programming error “ this could happen from a power surge or outage. In this case the thermostat would need to be reprogrammed.
Could have a bad thermostat.
Could have a short on the heat pump itself.
Could possibly be none of the above, though I would trouble shoot in this order.
After checking batteries and programming I would suggest contacting a trained HVAC technician to further diagnose the issue.
