What do our customers have to say?

"Just want you to know what a great help Larry was on Saturday. We had a very high profile client in to do a taping with 6 Oscar (to be nominated) actors. This client has done a lot of work with us and we hope will continue to do a lot of work here. I called Larry for advice. I then asked him to come in . . . I also called F.M. Thomas service and let them know I had called Larry directly, and had asked him to come in. I have implicit trust in his (Larry's) knowledge and judgment. We averted a major meltdown of the taping and the relationship with the client. He (Larry) is also the reason I won't entertain bids from other vendors for HVAC services." R.K.

"Our system is quite complex, both in terms of the control system, and the layout. Almost everything is hidden away in the ceilings. It has been a major effort to understand the system. To have a new guy come in and spend half a day figuring out the system and layout doesn't work for me, especially in an "emergency" situation. William, who does our filters, understands the layout since her services the unit, and has the ability to diagnose the problem and solve it." Anon.
