WHO WE SERVE

Commercial HVAC Installation for Every Property Type

We install HVAC systems across a wide range of commercial property types throughout Livonia, Northville, and Plymouth. Each property type has different requirements, and we know the differences.

Office Buildings

Single and multi-tenant office spaces require consistent, quiet HVAC performance across individual suites and shared spaces. We design and install systems that maintain comfort without disrupting office environments — and schedule installation to minimize downtime.

Retail & Storefronts

Retail environments have high foot traffic, variable occupancy, and front-of-house comfort requirements that directly affect the customer experience. We install systems sized for commercial occupancy loads — not residential estimates applied to commercial spaces.

Restaurants & Food Service

Restaurants present unique HVAC challenges — kitchen exhaust, make-up air, dining room comfort, and ventilation requirements that must meet health code. We're experienced with the specific demands of food service HVAC and the code requirements that apply.

Medical & Dental Offices

Medical facilities require precise temperature and humidity control, proper ventilation between rooms, and systems that operate quietly enough not to disrupt patient care. We install commercial systems that meet the specific demands of medical office environments.

Warehouses & Light Industrial

High-bay warehouse and light industrial spaces require commercial heating and ventilation systems sized for large open volumes, loading dock exposure, and the specific occupancy and process loads present in the space.

Multi-Tenant Commercial

Strip malls, multi-tenant office buildings, and mixed-use properties require individual unit systems or shared HVAC infrastructure with proper zone separation. We handle multi-unit commercial scopes from a single point of contact.

SYSTEMS WE INSTALL

Commercial HVAC Systems We Install in Southeast Michigan

Commercial HVAC is not residential HVAC at larger scale. The equipment, installation requirements, and code considerations are different — and we install accordingly.

Packaged Rooftop Units (RTUs)

The most common commercial HVAC solution for flat-roof commercial buildings throughout Southeast Michigan. Self-contained units sit on the roof and connect to the building's duct system, lower mechanical room footprint, straightforward maintenance access, and a proven commercial platform for offices, retail, and light commercial.

Split Systems — Commercial Grade

Commercial-grade split systems for properties where rooftop units aren't practical. Separate outdoor condenser and indoor air handler configured for commercial occupancy loads and Michigan's heating-heavy climate.

Multi-Zone VRF / Mini Split Systems

Variable refrigerant flow systems allow individual zone control across multiple spaces from a single outdoor unit, ideal for multi-tenant offices, medical suites, or commercial spaces that require different temperatures in different areas simultaneously.

Make-Up Air & Ventilation Units

Commercial spaces with high exhaust requirements, restaurants, kitchens, paint booths, and certain industrial applications, require dedicated make-up air units to replace exhausted air and maintain proper building pressure. We size and install dedicated MUA systems as standalone units or integrated with primary HVAC.

Commercial Heat Pumps

Commercial heat pump systems offer the same efficiency advantages as residential heat pumps at commercial scale, lower operating costs, single-system heating and cooling, and potential eligibility for commercial energy efficiency incentives. Available in rooftop and split configurations.

Unit Heaters & Radiant

Warehouses, garages, and large open commercial spaces often require unit heaters, infrared radiant heaters, or destratification systems rather than conventional forced-air HVAC. We install the right heating solution for the specific space and occupancy, not a one-size-fits-all approach.

COMMERCIAL VS RESIDENTIAL

What Makes Commercial HVAC Installation Different

Commercial HVAC involves different equipment, different code requirements, and different installation considerations than residential work. Here's what that means in practice.

Commercial Mechanical Code

Commercial HVAC installations in Michigan are governed by the Michigan Mechanical Code, which has different ventilation, equipment, and inspection requirements than the residential code. Our commercial installations are designed and permitted to meet commercial mechanical code — not adapted from residential standards.

Occupancy-Based Load Calculations

Commercial HVAC sizing accounts for occupancy density, internal heat loads from equipment and lighting, ventilation requirements per occupant, and operational schedules — factors that don't apply to residential calculations. We run commercial-grade load calculations on every commercial job.

Operational Schedule Coordination

Commercial installations can't always happen during standard business hours — particularly in occupied retail, restaurant, or medical environments. We offer after-hours and weekend installation scheduling to minimize disruption to your business operations and your customers.

Commercial Permitting & Inspections

Commercial mechanical permits involve different documentation, plan review requirements, and inspection processes than residential permits. We handle the full commercial permitting process — drawings, permit application, plan review coordination, and inspections — through the appropriate jurisdiction for your property location.

HOW IT WORKS

Our Commercial HVAC Installation Process

A clear process from first call to final commissioning — designed around the realities of commercial installation.

Commercial Site Assessment

We visit your property, assess the existing HVAC infrastructure, review your space layout and occupancy requirements, and gather the information needed for a complete commercial load calculation and equipment recommendation.

Load Calculation & System Design

Commercial-grade load calculation accounting for occupancy density, equipment loads, ventilation requirements, and your building's envelope. We recommend the right system type, capacity, and configuration — with options at different price points.

Written Scope & Proposal

A detailed written proposal covering equipment, installation scope, permit costs, and timeline. No verbal estimates, no line items that appear after the fact. You know exactly what you're getting before you commit.

Permit & Schedule Coordination

We pull the commercial mechanical permit and coordinate the installation schedule around your business operations — confirming access requirements, after-hours needs, and phasing if the project requires it.

Installation

Our commercial crew completes the full installation — equipment, ductwork, controls, and all associated connections. We work cleanly, communicate throughout, and flag anything unexpected before proceeding.

Commissioning, Inspection & Handoff

Full system startup, testing, and balancing — we verify the system performs to spec before signing off. Mechanical inspection coordinated and passed. Documentation provided for your property records.

Commercial HVAC Installation Questions

Questions business owners and property managers ask most before scheduling a commercial HVAC estimate.

Can you install HVAC during off-hours to avoid disrupting our business?

Yes. We offer after-hours and weekend installation scheduling for commercial projects where daytime installation would disrupt operations or customers. We discuss scheduling requirements during our initial site assessment and build the installation timeline around your operational needs.

What size HVAC system does my commercial property need?

Commercial HVAC sizing is based on a commercial load calculation that accounts for your building's square footage, occupancy density, internal heat loads from equipment and lighting, ventilation requirements per Michigan mechanical code, and your building's construction and insulation. We run a complete commercial load calculation on every job — the right size is specific to your building, not a rule-of-thumb number.

Do you handle the commercial mechanical permit?

Yes. We handle the full commercial permitting process — application, any required plan review documentation, and inspection scheduling through the appropriate jurisdiction for your property location. Commercial mechanical permits involve more documentation than residential permits, and we manage the process so you don't have to.

How long does commercial HVAC installation take?

Timeline varies significantly by project scope. A single rooftop unit replacement for a small commercial space may be completed in one to two days. A full HVAC installation for a larger commercial building, multi-tenant property, or project with significant ductwork may take one to two weeks. We provide a detailed timeline in our written proposal before any work begins.

Do you work with property managers and building owners, or only direct business tenants?

We work with whoever is the right point of contact for the project — building owners, property managers, facilities managers, or business tenants coordinating with their landlord. If there are multiple parties involved in the decision or approval process, we can structure our proposal and communication to accommodate that.

Can you provide a certificate of insurance for our property records?

Yes. We carry full general liability and workers' compensation insurance and can provide a certificate of insurance naming your property or organization as an additional insured on request. Most commercial property owners and managers require this before work begins — it's a standard part of our commercial engagement process.
