I know sounds like a non geo question.. but its right down the geo ally... I have recently had a brand spanking new Bosch water to air installed down stairs and it works fine.. on for 10-15 min per hour and off for 45 min and cool and humidity free like a big dog.. However i have a Trane 2 ton installed upstairs.. and it runs 24x7 to keep up and when the temp outside reaches 80 degrees it can no longer keep up.. so not only runx 24x7 but no longer can maintain the temp at or near 75 degrees.. They have so far tried everything under the sun and they are about ready to give up.. with that is the best we can do.. WRONG! if it comes to that i will say FINE.. i will get off your back if you bring me a letter from Bosch or Trane that states its perfectly NORMAL to have the unit run 24x7 and fail to hold the temp past 80+ outside... LOL. So what are the odds that a mfg would write such a letter.. hopefully they will say pack it and upside to 3 tons.. My conditioned space is approx 800 square feet so 2 tons should do it since i am well insulated.. but just makes no sense.. I am hoping to get them to remove the Trane and replace it with a Bosch.. i really do like bosch better than trane... So folks keep your fingers crossed and i will let you know what happens... please give me some comments.. am i in left field or do i have a right to demand they get the temp under control and stop the 24x7 (hely terror on electric bill) or step the size of the unit up a notch at their expense.. What do you think?
