Rockford & Loves Park Commercial Test & Balance

Occupancy Permit Verification for the I-90 West Corridor

Building code enforcement in Winnebago County is changing. With the adoption of the Northwest Illinois Regional Building Code and the strict 2021 International Energy Conservation Code (IECC), commercial projects in Rockford and Loves Park face tighter mechanical inspections than ever before.

If your HVAC installation is complete but the city inspector is demanding a certified Test and Balance (TAB) report before issuing your Certificate of Occupancy, Northwest Energy LLC is your solution.

We provide independent, rapid-response Commercial Test and Balance services for General Contractors, MEP Engineers, and Business Owners throughout Rockford, Loves Park, Machesney Park, and Belvidere.

1. Beating the Inspection Bottleneck

A delayed occupancy permit costs you money. We specialize in closing out your permits fast.

• IECC & IMC Compliance: We verify that your Rooftop Units (RTUs), Exhaust Fans, and Make-Up Air Units meet the exact airflow metrics (CFM) demanded by the 2021 mechanical codes.

• HVAC Contractor Partnerships: We act as your independent TAB subcontractor. We do not perform service or install work, meaning we never compete for your maintenance contracts. We simply provide the  data you need to release your retainage.

2. Industries We Serve in Winnebago County

We bring specialized air physics expertise to Rockford's growing commercial sectors.

Industrial & Manufacturing (I-90 Corridor)

Rockford is an industrial powerhouse. Massive warehouses and manufacturing floors suffer from severe thermal stratification and building pressure imbalances.

• We test and balance high-bay heating, exhaust systems, and MAUs to correct Negative Building Pressure.

Restaurants & Kitchen Build-Outs

Opening a dining concept near Downtown Rockford or East State Street?

• The local health department requires strict smoke capture and exhaust rates.

• We provide comprehensive Restaurant Kitchen Hood Balancing to ensure your kitchen exhausts properly without pulling freezing winter drafts into the dining room.

Medical & Dental Clinics

Healthcare facilities require far more than basic comfort cooling.

• We provide precise Medical Office Air Balancing to verify Air Changes per Hour (ACH) for infection control and ensure patient privacy by managing sound transfer through ductwork.

3. Why Choose Northwest Energy LLC?

While many contractors look for TAB services in Chicago or Naperville, we specifically service the I-90 West corridor to bring high-level compliance testing directly to Winnebago County.

• No Hourly Guesswork: We use a predictable, Flat-Rate Pricing model based on your equipment list.

• Ventilation Assessments: We measure Outside Air (OA) intake to verify your building meets ASHRAE 62.1 standards for indoor air quality and occupant health.

• Problem Solvers, Not Just Testers: If a system is underperforming, we don't just hand you a failing grade. We work with the on-site mechanical team to adjust sheaves and fan speeds to get the numbers passing.

Frequently Asked Questions

Q: Does the City of Rockford require a TAB report for a Certificate of Occupancy? A: Yes. Under the recently adopted 2021 ICC code family, new commercial construction, major renovations, and "Change of Use" permits require verified mechanical airflow data before final sign-off.

Q: Do you charge a travel fee to Loves Park or Rockford? A: Because we frequently travel the I-90 corridor, we build our travel efficiency into our flat-rate bids. Send us your drawings for a transparent, out-the-door price.
