Fardeen Ferozi from John Flood was here today to work on a couple of things that he had recommended we replace/upgrade. We were happy with his first visit. Fardeen gave us careful explanations of his work and the work he suggested. The second visit was equally successful. He worked on our electrical surge protector and cleaned the outdoor condenser, which needed it :). Fardeen himself is a very nice person. Polite, friendly and industrious, and very appreciative of cold drinks and his deserved gratuity. Happy customers here! Cheryl & Richard

The company provided us a couple of portable units, to go along with our own, which kept the condo sufficiently cooled during some serious heat indexes in DC. The job itself took a week to begin (after our financial commitment with a down payment), due to late arrival of some parts.

What was presumed to… read full review
