We have had numerous projectors serviced by Projector Doctor and have also purchased projector lamps from them. The service is always swift and tremendous! I could use a company that is closer, but why mess with perfection?

Susan is my rep at Projector Doctor and she’s a delight to work with. I ask for a quote and within an hour or two, I have a quote. Some of my vendors will take days to get me a quote.  And every order so far has arrived on or before the projected ship date. So that’s excellent service.

We have never had any problems in obtaining any projector lamp that we order.  Projector Doctor always comes thru in getting anything that we need. The communication between the parties is great. It is a pleasure to deal with such an organized and friendly company.

Just wanted to let you know that Dar, who handled our service repair for a very expensive projector, was AMAZING. We needed the repair quickly because we had a client that was very upset about the projector having to be pulled and she handled everything for us and was right on top of communicating every to us every step of the way, even with a holiday weekend to contend with! We got the piece back today and the client is thrilled. Just wanted to thank you and tell you what a wonderful experience it was, thanks to Dar! and your service team 🙂

One of my team sent a unit for repair. In the interest of time and schedules on our side, we opted instead, to cancel the repair and quickly replace the unit. Susan Williams was incredible in her timely responses and customer relational approach. The company cheerfully worked with us on the diagnostic charge and recycled the unit for us. That afternoon the team member discovered that the mounting unit was mistakenly sent with the repair. Upon this news I called Susan who was immediately able to contact her tech in Atlanta, recover the mount, catch UPS and overnight it to us for our install the next day. I have been Directer of Tech Arts for 11 yrs and daily handle AV repairs. Susan and Team: this was truly an incredible customer service experience ! Thanks much !!

We send gear to Projector Doctor from 9 different offices for repair. The have always been timely, fair priced, and most importantly stood behind there work. I will continue to be a client.

Beware of Generic Lamps. Projector Doctor does NOT recommend or sell low quality generic projector lamps. Generic projector lamps are built using the substandard components and build techniques that result in a dimmer and shorter life for the lamp. These low-quality lamps can damage the projector itself causing safety concerns and voiding your projector’s warranty. The pricing on these lamps can be very attractive, but you will get what you pay for. Buyer beware.
