I use to work for the company and I noticed for a new resume that I needed some information about the past and I believe Tina Diemer's customer service was really helpful for locating that type of information, God bless you for being kind and honest, wishing your company much success

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.

Truck 599 Learn how to drive and be aware of your surroundings. On a closing lane you speed up or slow down. This person started merging into me without even looking into the left lane. I couldn't move left due to the lane being occupied so so right as this dummy turns into me I had to hit my brakes on a freeway. 6:45 5 south April 17th.

I can not describe how good it was to work with Peggy at A.O. Reed & Co. She is a master of her craft and demonstrated the best customer service that I have ever gotten.

I visited the store today as I needed a plumbing fixture after going to Ace and the Home Depot, both of whom recommended that I visit A O Reed as they were plumbing specialists. Ace and Home Depot were experienced, pleasant and helpful. The opposite was true of the elderly person behind the counter at A O Reed, he was unhelpful, unpleasant and generally clueless and useless. With his kind of service it will only be a matter of time before they go belly up, I intend completing a major renovation of my home in La Jolla and will not allow the contractors to buy from them.
