I just wanted to take the time to compliment Michael, too many times we hear a lot of complaints and not enough compliments. Michael is a very kind person who obviously cares about his job his attitude proves it. He had to walk back and forth through the office to get to thermostats and check the temperatures several times and everyone who interacted with him just had nothing but positive things to say about him. We enjoyed having him!

I really appreciate all your help in getting the repairs completed on both our Liebert and chiller units. It is an understatement to say that we are impressed by the professionalism, knowledge and ability of Stephen T. You mentioned that he is new to your organization, and he is a true blessing to our company. He has been right there, helping out wherever and whenever this past week. From providing immediate repair, to primary research into the problem, to clear communication and follow-through, we could not have done it without his expertise, thoroughness, and patience.

I am writing to compliment Greg on his tenacity and commitment to fixing the boiler. Our house is warm and comfortable. I have monitored the boiler and it is striking first time each time I check it out. Please give Greg my thanks. He promised he would get it done and he did.

- Killis A., FAIA

I just wanted to say thank you for the quick service response we received today. I am a very happy customer (much cooler too)!

- Nancy York, Purchasing, Navarro ISD

I didn't get the typical you need x, y and z other items. It was just fixed. The price was more than fair and the attention to detail (and service) was off the charts. There is something to be said for making the customer the first priority and backing it up. I would recommend Barrett & Sons to anyone.

- Mike K., S.A.

Thank you, Todd, for all your assistance. Wonderful to have someone to trust and count on from so far away!

- Ida C., N.C.

I don't write reviews as a general rule of thumb for anyone, but this company went above and beyond my expectations, not once but twice now. If you have any type of issues with your heating or AC, call this company. You won't regret it.
