About Us
A commercial mechanical contractor, not a side job
Richard A Demars Inc works on commercial plumbing and HVAC systems — the kind that run at pressures, volumes, and duty cycles residential work never touches. That focus is the whole point.
Who We Are
Built on the work, not the pitch
Commercial mechanical work is a discipline of its own. A building's water and air systems are sized, pressurized, and regulated to standards that don't apply to a house — and the consequences of getting it wrong fall on tenants, customers, and inspection reports.
We stay in that lane deliberately. By working exclusively on commercial properties, we carry the licensing, insurance, and hands-on experience that this work actually requires — and we bring both trades with us, so plumbing and HVAC don't become two separate contracts, two schedules, and two sets of opinions.
The result is straightforward: one contractor who can diagnose a system, quote it honestly, pull the permits, do the work, and hand you the documentation when it's done.
How We Operate
What you can expect on every job
These aren't slogans — they're the standards we hold ourselves to on commercial work, where the margin for guesswork is small.
Licensed & insured
Fully credentialed for commercial mechanical work, with the insurance coverage commercial property owners require before anyone touches their systems.
Code compliance as standard
Permits pulled, inspections coordinated, and documentation delivered. You get the paperwork your records and your insurer need.
Both trades in-house
Plumbing and HVAC under one contract. No coordinating between vendors, no gap where each side blames the other.
Scheduled around your operation
Overnight, early-morning, and weekend slots available so tenants, customers, and staff aren't disrupted.
Straight answers on scope
Written scope and clear pricing before work begins. If a repair will do, we'll tell you that instead of quoting a replacement.
Reachable when it matters
A number that answers at 2 a.m. Emergency dispatch is available around the clock, every day.
Let's talk about your facility
Whether it's a repair, a planned replacement, or a maintenance program you've been putting off — start with a conversation.
