    Thanks, I confirmed that in the specs. I wish it would go lower. The balance point is low-mid 20's with typical NC cold dry air. It is probably in the low 30's with precipitation which we have had...

    The house is unoccupied during the day and I see no good reason to spend money heating and cooling it during this time. Winter setback is 62 from 70. Summer setback is 85 from 75.

    Thanks for the info. 40 degrees seems kind of high to be kicking on the (COP=1) heat strips. What is the COP of the heat pump itself at this temperature. For my climate I would like to see 30-35...

    Good point! The warranty is through American Standard Warranty company (ASWC) which appears to be Trane and not some third party. I dug through my paperwork and in the warranty under section A-6...

    Thanks for the feedback. I still have 3 years on the extended warranty. Hopefully, any "weakening" of the compressor or fan motor will show itself before then.

    My old system blew a blower cap. The...

  11. Failed Run Capacitor = Collateral Motor Damage?

    Hello,

    My Trane XL15I system died once again. This time it was a failed run capacitor. It was starting to make more noticeable compressor vibrations which get transmitted into the air handler in...

    My Trane XL15I recently blew it's dual run capacitor. The tech left me the original cap and the box the replacement came in.

  13. Heatpump Heat Strip Outside Temperature Lockout?

    I was sold a Trane XL15I system several years ago. It came with the Trane equivalent of the Honeywell TH8320 programmable thermostat with an outside temperature sensor.

    I was told by the...

    Any idea what these chemicals are and where they come from? This house is 33 years old so there are no building materials to outgass, no new furniture, no new carpet, and no Chinese drywall etc. The...

    Teddy Bear,

    I am not sure. What does a "copper spun" filter look like? Is it part of the compressor assembly or piping? A picture would be helpful here.

    Green Copper Evaporator Coil Corrosion?

    Just out of curiosity which particular models were they and what kind of problems did you see? Any recommendations for better products?

    HVAC Folks,

    Thanks for everyone's response. I definitely agree that heat strips are not a cost effective way to recover temperature.

    Is Temperature Setback Hard On Heat Pumps?

    A recent compressor failure in a 5 1/2 year old Trane XL15i has me wondering if setbacks could be a potential cause of the failure.

    Thanks for the heads up on the outside TXV and specifically what to look for. If you're right I owe you at least a beer and maybe a case!

    Thanks for the tip! I did actually track down the local DSO (NOT an easy task!) to confirm that the dealer shouldn't be trying to charge me $$$ for refrigerant that should be covered under the...

    Alright, I'll bite. How can I as an end user cause a compressor to fail in a little over 5 years? This was a complete new system including all new ductwork.




    Well, now you have a data point...

    Yes, but it appears that the warranty is through Trane. I could probably go to another Trane dealer but don't know if I would end up with someone even worse. One would think that the installing...
  45. FUTURE System Reliability AFTER Eating A Compressor
