I just bought this house about 2 weeks ago and the cooling is inadequate in my opinion. I will star with unit specs.
1550 sqft with 3 ton trane heat pump. Model 2twb0036a1000ab
I had condenser coils and evap coils cleaned they were extremely dirty. I am only getting about 10 degrees from outside temp. I have now had 4 techs look at system and all say something different so I am confused as ever. My pressures were 80 suction and 185 head with outside temp being 85 and inside 75 with unit never getting below this. During the 95-100 temp days I am seeing 85-87 inside my home with unit never cycling off. I have measured my air temp many times and at night i get about a 13 degree air temp difference in return to supply air. In heat of day i get about 7-10 at best return to supply air temp difference. Unit is 6 years old. I was told this is all the unit will do by one the other said coil was still dirty he thought and last tech said could be my compressor going out. Please any help would be appreciated as I have a lot of money tied up in this already and still not working correctly. Thanks
