Customer Quotes Of The Month

  • "AJ Warren Service Co is a very well managed and well run company. They are dependable, knowledgeable and thorough. We now use them for both our residential and commercial AC/Heat maintenance and service. I highly recommend them.", Cathy P., Houston, Texas 77043, 1/19/2015
  • "Mark, Just wanted to let you know that we’re still very happy with the system. In fact we still haven’t spent more that 85.00 for an electric bill yet. We just received the May - June bill and it was 84.00 compared to over 200.00 last year. Air quality and comfort is just great. With the old system it was either on or off and you just could never get it perfect. With this variable-speed system the air is always exactly right and most of the time you don’t even know it is on. If you ever have any customers doubt that it is worth it just pass my comments along - your complete package of engineering the air handling, sizing the system, and recommending other contractors was great. Anybody can go and buy some boxes of AC equipment and slap it in but doing it properly really makes a difference. Thanks Again.", Tim Fitzhenry, Houston, 6/16/2014
