The challenge
Deliver clinical-grade ventilation and comfort for a brand-new dental practice on a fixed opening date.
What Mash installed
Complete HVAC package with dedicated operatory ventilation, exhaust and building controls.
What made it difficult
Operatory air changes, equipment exhaust and quiet operation all had to fit within a compact ceiling plenum.
The outcome
A quiet, code-compliant clinical environment delivered on schedule with Optimum Construction Co.

Project Overview
Mousam River Dentistry is a purpose-built dental practice delivered with Optimum Construction Co. Mash Mechanical installed the complete mechanical package — heating, cooling, ventilation and controls — for the reception areas, operatories, sterilization suite, lab and support spaces.
Dental offices demand quiet, consistent comfort and dependable air changes. We zoned the building so treatment rooms hold steady temperatures independently of the waiting area, kept equipment and ductwork tucked out of sight above the finished ceilings, and coordinated closely with the trades so the mechanical work never intruded on the clean, residential-feeling interior.
Scope of Work
- • High-efficiency heating and cooling equipment
- • Zoned distribution for operatories and public areas
- • Ductwork and diffuser layout coordinated with finishes
- • Ventilation and exhaust for sterilization and lab spaces
- • Thermostats and system controls
- • Test-and-balance and commissioning
