Real reviews from real South Jersey homes.
Verified Google reviews from S&M Mechanical customers.
"After our a/c system went belly up 1 month into our home purchase, and mid-heat wave, Scott fit us in on short notice, explained our options and associated price points, leaving to us how much to patch vs overhaul without a hard sell. I've used a large company for years satisfactorily but they've never explained things as well or been as conscientious as Scott. He backs up his work with a no b.s. personal warranty so I won't be going back to the corporate folks ever again. He also addressed my wife as an equal vs the usual condescension."
"Nothing but great things to say about this company. Fantastic honest family business. Care about the clients and don't want to waste their time or your time and money. Great values. Best company I've hired to do work at my home. Definitely would recommend and hire again."
"Scott & team from S&M Mechanical were reliable & accommodating. We did away with our boiler & water heater for a tankless heating system. Great value for a great price! We highly suggest S&M. Thanks again!"
