I apologize if this is old hat but any help would be greatly appreciated as I'm EPA certified but not well versed in R410. We had a complete system installed about 2 years ago still under warranty, hence my reluctance to work on it myself.
Yesterday the indoor temp was rising with both the air-handler and condensing unit running. The tech taped up some gaps on the indoor unit and added some refrigerant.
Today, although maintaining 77 degrees, the unit is running near constantly. Ambient is 95 degrees and we're getting a split of near 20 degrees. The outdoor unit sits in the shade and the air coming off the condenser is 108 degrees.
My question is really about head pressure. When I looked at the gauges the tech had on the unit I noticed a "normal" suction pressure of about 150psig but head pressure was 490psig and am concerned that this is too high.
Again, sorry to re-hash topics but I have much to learn and I've heard great things about this site. Thanks for any help provided!
