What We Do

Full-Scope Services,
Zero Shortcuts

Every engagement is built around your specific project. We don't offer cookie-cutter packages — your building is unique, and your HVAC and roofing strategy should reflect that.

01

HVAC System Design

From load calculations and duct layout to equipment selection and zoning plans, we engineer HVAC systems built for peak performance, long-term reliability, and energy efficiency — tailored to every structure's unique demands.

Contractor Vetting & Oversight

We source, evaluate, and manage licensed HVAC and roofing contractors on your behalf — reviewing bids, verifying credentials, enforcing scope, and conducting quality inspections at every milestone so work is done right the first time.

Diagnostics & Troubleshooting

Persistent comfort issues, energy spikes, or unexplained leaks require more than guesswork. Our diagnostic process combines site analysis, equipment data, and thermal readings to identify root causes and prescribe precise, cost-effective solutions.

Code Compliance & Permitting

Navigating local building codes, energy standards, and permit requirements is complex. We guide projects through compliance from design to final inspection — preventing costly rework, delays, and liability exposure.

Preventive Maintenance Planning

Reactive repairs are expensive. We develop structured, schedule-based maintenance programs for both HVAC and roofing systems that extend asset life, reduce emergency call-outs, and keep operating costs predictable year-round.

Our Story

Built on Expertise.
Driven by Integrity.

MJ Consulting was founded on a simple principle: property owners and project managers deserve an independent expert in their corner — someone whose only loyalty is to the quality of the work, not the contractor performing it.

With over 15 years of hands-on experience across residential, commercial, and industrial projects, our consultants bring technical depth that flags problems before they become costly failures — and holds every contractor accountable to the standard your project demands.

Why MJ Consulting

The Difference
An Expert Makes

Most property owners don't discover problems with their HVAC or roofing work until something fails. We exist to change that — by putting certified expertise on your side from the very beginning.

Truly Independent

We have no financial relationship with any HVAC manufacturer, roofing supplier, or contractor. Our recommendations are driven solely by what is best for your project.

Deep Technical Knowledge

Our consultants hold industry certifications and bring 15+ years of field experience. We read blueprints, analyze thermal data, and evaluate membrane systems at a level general contractors cannot match.

Contractor Accountability

When you hire a contractor, they answer to themselves. When MJ Consulting is engaged, they answer to us — and through us, to you. We review every bid and inspect every milestone.

Code & Compliance Mastery

Local building codes, energy standards, and permit requirements change regularly. We stay current so you don't have to — preventing violations, rework, and legal liability.

On-Time, On-Budget Delivery

Scope creep and schedule slippage are industry norms — but they don't have to be. Our project management discipline keeps HVAC and roofing projects on track from kickoff to close-out.

Long-Term Partnership

We don't disappear after the job is done. MJ Consulting clients access ongoing support, annual condition assessments, and maintenance planning that protects their investment for years.
