  I used to like this company for back-flow testing every year but   they would raise their prices every year. At first I didn’t think much of it because everything is going up on price. However I contacted several plumbing companies who do back flow testing and this company was the most expensive!  Not by a little but by a lot!! So I switched.  Very sad because I liked their customer services.

  I have an annual contract with A.O. Reed & Co. for quarterly maintenance of the HVAC system at my business downtown. This is the fourth HVAC maintenance company I've worked with since 2017, and it is SO REFRESHING to work with the professional experts at A.O. Reed & Co.
Omar was in my shop this morning for quarterly maintenance. It was good to see him again. He knows exactly what he's doing, and always explains it to me very clearly, showing me what he's referring to when necessary, and even breaking down various options when repairs are necessary. This is top-notch service at a very reasonable price.
I recommend without hesitation or reservation.

  We've had them forever, a few newbies fall short in respecting the customer. You are in someone's home respect is everything. Overall I give high marks to AO Reed. They do an excellent job.  They don't hire thieves.
