[QUOTE="Viper16, post: 2776511, member: 1558"] If it were me, I would find out my delta t from the supply/return based on the type of system you have installed. I would expect around 15-20 degrees. That could mean your system is doing the best it can for the current conditions (outdoor/indoor). If the delta T were struggling, I would check the evaporator coil for blockage, check filter, then I would look at condenser coil and make sure it is clean and free of debris, and open to fresh air. I would then have a refrigeration tech check the sub-cooling and pressures. If they are out of design, could be blocked expansion valve, or something fouled in the piping. [/QUOTE]
