Our Story
All Environmental Services was founded on a simple principle: commercial clients deserve a contractor who shows up, does the work right, and stands behind it. What started as a small HVAC service operation on Long Island has grown into a full-service mechanical and electrical contractor handling complex commercial and industrial projects across Long Island, New York.
Over the decades we've built lasting relationships with property managers, general contractors, restaurant groups, retail chains, and facility teams who rely on us to keep their systems running. Our reputation is built on honest assessments, clean installations, and technicians who treat every job — large or small — with the same level of care.
How We Work
Honest Assessments
We tell you what your system actually needs — not what generates the biggest invoice. Our recommendations are based on what's right for your building and budget.
Clean, Code-Compliant Work
Every installation meets New York State code requirements. We pull the permits, schedule the inspections, and leave the job site clean.
Responsive Service
When something breaks, you need someone who picks up the phone. We offer 24/7 emergency service because downtime costs money.
Single-Source Accountability
HVAC, refrigeration, and electrical under one roof. One point of contact, one invoice, and no finger-pointing between trades.
Licensed, Certified & Insured
All Environmental Services holds all required New York State licenses for HVAC, refrigeration, and electrical work. Our technicians are EPA 608 certified for refrigerant handling. We carry comprehensive general liability and workers' compensation insurance on every project.
Where We Work
We serve commercial and residential clients throughout Nassau and Suffolk County, New York. From Hempstead to Montauk, our crews are local and familiar with the municipalities, inspectors, and code requirements across Long Island.
