About E&A Mechanical in Westminster, MD
A family business where the owner still turns the wrenches.
Our Story
Clear Communication. Quality Work. No Surprises.
That line is not a slogan we bought. It is how E&A Mechanical actually runs. Mike started the company to do HVAC the way he would want it done at his own house. Show up on time. Explain the problem in plain English. Quote the price before touching anything. Leave the work area cleaner than he found it.
Today the crew is still small on purpose: four technicians and one office. Small enough that every job gets owner-level attention. Established enough to handle a capacitor swap or a crane-set commercial rooftop unit.
The scoreboard that matters most: a 5.0-star Google rating across 431+ reviews, written by homeowners across Carroll County who mention the crew by name.

The Crew
Mike Patterson, Owner & Master HVAC Technician
Holder of Maryland master HVAC license #59288, and still on the tools. Diagnoses with instruments, explains in plain English, and answers for every job that carries the E&A name.

The technicians in the wrapped vans. Trained on everything from oil furnaces to ductless mini-splits, and mentioned by name in the reviews.

The voice on the phone and the texts that keep you updated. Scheduling, follow-ups, and making sure nothing falls through the cracks.
