We install over 600 UPS systems every year for businesses nationwide. Discover what our clients have to say about their experiences with Carter Sullivan below.

The site contact who oversaw the work last night was that the Carter Sullivan engineers were “the best he’s ever seen”. They removed all of the old UPS equipment and batteries and took back all of the packaging materials leaving both comms room in a “very tidy state”. It’s not often we get positive feedback like this so I thought I would let you know – please pass this back to Lee and his colleague!

Site called and asked if you could pass on his comments to the engineers – efficient, extremely polite, clean and tidy, appreciated them wearing masks at all times, he really was genuinely pleased with the way they worked, a huge thank you from me too because you certainly make my life a lot easier when it comes to installation.

“I wanted to say thank you myself for Jamie originally spotting the swollen batteries on the adjacent systems in the room where he is currently working and informing us immediately.

This is especially important as it is people on the end of these units not machines so both Joe and myself express our thanks to Jamie for being so observant and helpful with the situation.
