Our York Heat Pump is not doing a very good job cooling. Yesterday, the temperature soared up to 91 degrees and we had 60% RH outside. Upstairs, the t-stat was set on 73, however, the system could not get the temp down bellow 75 until the late evening. Went outside to look at the unit and I noticed that the Suction line going into the unit did not seem very cool to the touch. The liquid line, however, seemed warm like it should. I compared the temps to our York Condensing unit and the Suction line seemed much colder to the touch. Also, usually there is no of condensation on the HP Suction line and around the uint. Last cooling season there was much more condensation around the unit. Inside the house, the supply temperature did not seem as cold as it did last cooling season. Our service people are coming for the spring inspection next week but I just wanted to see what you guys thought.
