Rooftop units, crane sets, and the maintenance that keeps your building open.
Install & Repair
When a shop, office, or multi-unit building loses heating or cooling, it is not just uncomfortable — it costs business. E&A Mechanical installs and services commercial HVAC across Carroll County, from packaged rooftop units set by crane to the split systems serving storefronts and offices. The crane-lift photos on this page are our own jobs, not stock imagery.
Rooftop and packaged units staged, crane-set, and commissioned — see our own job photos above.
We plan the work around your operating hours so the changeover does not close your doors.
Repair, replacement, and maintenance from the same local crew — with a 24/7 line behind it.

The tech finds the real problem and explains it in plain English, with the price before any work begins.
Work done, system tested, everything cleaned up — "as if he was never there," as one review puts it.
Packaged rooftop unit replacement and installation, including crane coordination and rigging day logistics. Split systems for storefronts, offices, and mixed-use buildings. Ductless systems for server rooms, additions, and spaces the main system never reached. Ongoing maintenance that keeps warranties valid and energy costs in line.
A national service contract sends whoever is available from wherever they are. We are based in Westminster — when your building's heat fails on a February morning, the crew that knows your equipment is minutes away, not hours. And because the same techs return each visit, the fixes build on real knowledge of your system instead of starting from zero.
