Home had an existing Trane 5 ton system. Back in 2009 we had the system replaced to get a more efficient unit and take advantage of tax credits. Electric bill use to be 300+ now we are only paying 150-200 which is great!
The proposal was to replace it with another 5 ton system model #s 4TEE3F60 and 4TWR5060. From my understanding these are both 5 ton units. I just now noticed the units that were installed was 4TEE3F65 and 4TWR5048. I believe this is a 4 ton condenser and 5.4 ton air handler?
Before I go back and question what happened with the install I just wanted to know if this was okay to do. From my understanding the AHU should not exceed more than .5 ton than the condenser unit. The system has been saving us money but the quality of the air didn't seem as comfortable as the previous unit in terms of humidity.
Please give me any thoughts about this situation. Thanks!
