Install. Service. Support.
MMS stands for Master Mechanical Solutions — a Metro Detroit contractor serving facility managers, building owners, developers, and homeowners who expect their mechanical systems to just work.
We specialize in Variable Refrigerant Flow (VRF) systems, large-scale cooling, mechanical audits, and industrial filtration. Whether it's a 200,000 sq ft manufacturing floor or a custom residential build, we bring the same discipline to every project.
The Philosophy
Invisible by design. Precise by discipline.
We believe a building's mechanical system should be invisible — quietly regulating temperature, humidity, and air quality without ever demanding attention. When it does demand attention, we believe in precision — diagnosing the real cause, not just the symptom, and delivering repairs that last.
— The MMS Team
02
Relentless Responsiveness.
We believe communication is everything. From the first call to long after the installation is complete, we stay accessible, proactive, and accountable. No unanswered calls. No disappearing after the job is done.
03
A relationship, not a transaction.
We take on clients we expect to work with for decades. Service contracts, preventive maintenance, seasonal check-ins — the best HVAC relationship is one where nothing surprises you.

Spotlight
Why VRF is the future of commercial comfort.
Variable Refrigerant Flow systems use inverter-driven compressors to deliver only the heating or cooling each zone actually needs — in real time. The result: up to 30% lower energy costs, simultaneous heating and cooling in different zones, and quieter operation than any conventional split system.
- Zone-by-zone control without the ductwork footprint
- Heat-recovery models recycle waste energy between zones
- Ideal for retrofits, additions, and multi-tenant buildings
- Manufacturer-certified MMS installation and service

Client Reviews
What Metro Detroit says about MMS.
Five-star reviews from the real clients — homeowners, facility managers, and building owners — we've served across Metro Detroit.
"When the original installing contractor wouldn't return my calls, I turned to MMS. Their team responded immediately, quickly diagnosed the issue, and got my VRF system back up and running without delay."
"When our water heater died, no one else had the courtesy to return our calls. A friend referred us to Master Mechanical Solutions. We experienced a fast response, quality workmanship, for a very reasonable price. They have become our go-to company for all our heating and HVAC needs. Highly recommended!"
"I highly recommend Master Mechanical Solutions. I had 2 services completed recently. They flushed my tankless water heater and added a filter for the tankless to ensure any impurities are removed. Brendan was great to work with. Was on time and gave me a heads up that he was on his way. After install was done he cleaned up any debris and spent time to walk me through what was done and how to replace the filter in the future. I will be using them in the future for all my HVAC related needs."
