Comment: Dealing with Trinity we had a tech come out after hours to say that he had never seen the system with the pressure's that it had and had to ask his boss. I called back the next day to talk to the boss or someone with some knowledge and they still had now idea. I contacted Bock Services llc, and Robert Perkins came to check out my system. He determined I had compressor failure. No big deal right I ask him is that normal for a five year old system, he said absolutely not. he asked if it ran continuously, I told him yes it never shuts off. Come to find out when Trinity installed it five years ago it was the wrong size unit for my house. I got the the right size unit installed at a awesome price, that couldn't be beat. Best experience with a ac tech I've ever had. And had no problem with answering questions and concerns as they arised. My system has kept my house at a constant 72° in 103° weather with only running for 5-10 minutes I cant wait to see my bill go down. I would definitely recommend this company for the professional and timely response time.. further more I would suggest to any customer to ask for tech Robert Perkins for honest answers and professional opinion. To you Robert thank you.!
