After having another company come out and advise me I had a slow leak and due to it being R22 would need to consider replacement, I contacted Diamond Blue to see if they could repair leak to get another year out of unit. They responded to advise me that there was no leak, the R22 was full in the unit and it was operating efficiently and effectively at the time of service. I was relieved that a new unit was not quite necessary at this time in complete contrast to the first company who came out two weeks earlier. I am getting 18 degrees temp differential, which was why I questioned first company in first place.I will not need to look any further for my future needs!Thanks guys!!PS: the technician Stephen! What a breath of fresh air. Knowledgeable, professional, helpful! What more can you ask for!

Sherman was very professional. He made sure to change shoes when coming inside versus the wet grass outside. Explained what needed to be repaired and took care of the problem.

Tech was on time and professional. I have a mini split that is not cooling properly. Added refrigerant and got a 24 plus degree drop acros the coil on a hot day. If happens again a lek test may need to be done.
