Chicago Commercial HVAC Installation: A Step-by-Step Guide

Installing a commercial HVAC system in Chicago is more than just plugging in new equipment—it requires thoughtful planning, expert execution, and compliance with local codes. Whether you're upgrading an outdated system or installing one for a new commercial build-out, understanding what to expect can save you time, money, and hassle.

At Planz Heating & Air Conditioning, based in Villa Park, IL, we’ve helped countless Chicago-area businesses stay comfortable year-round. Here’s what to expect from a commercial HVAC installation project from start to finish.

1. Initial Consultation and On-Site Assessment

Every successful HVAC installation begins with a detailed consultation. A technician from Planz Heating & Air Conditioning will visit your commercial property to assess your building’s:

• Size and layout

• Occupancy levels

• Current HVAC infrastructure

• Unique heating, cooling, and ventilation needs

This evaluation allows us to tailor a system that matches both your building and your business operations. Whether you're managing an office space, retail environment, or industrial facility, custom planning is key to long-term comfort and efficiency.

2. HVAC System Design and Equipment Selection for Chicago’s Climate

Chicago weather is no joke—sweltering summers and freezing winters demand a system that can handle both extremes. That’s why equipment selection is so critical.

Our team will design a system based on your building's needs, choosing between:

• Rooftop units

• Split systems

• Packaged units

• Heat pumps

We prioritize energy-efficient systems that reduce operational costs and support environmental responsibility. Brands and models are carefully selected to perform reliably in Chicago’s seasonal shifts, ensuring your business stays comfortable without driving up your energy bills.

3. Step-by-Step Commercial HVAC Installation Process

Our commercial HVAC installation process follows a proven workflow to ensure quality and safety:

1. Site preparation and removal of old equipment

2. Installation of new HVAC units

3. Electrical wiring and ductwork adjustments

4. Thermostat setup and zoning configuration

5. System calibration and fine-tuning

Throughout the process, our licensed technicians maintain a clean job site, adhere to all codes, and minimize disruptions to your business operations.

4. Handling Permits and City of Chicago HVAC Inspections

Chicago’s building codes are strict—and rightly so. Every HVAC installation requires the appropriate permits and inspections to ensure safety and code compliance.

Planz Heating & Air Conditioning will:

• File and obtain all necessary HVAC permits for your project

• Coordinate with city inspectors

• Ensure that your system passes all checks on the first try

This step is often overlooked, but failure to comply can result in project delays and penalties. Our team manages it all for you.

5. System Testing, Commissioning, and Client Handover

After installation, we enter the commissioning phase—a critical step to confirm everything is working as designed. This includes:

• Testing airflow, temperature regulation, and control settings

• Verifying energy efficiency performance

• Making any final adjustments for optimal function

You’ll receive a full walkthrough of the system, including how to operate the controls, recommended maintenance schedules, and who to call for support.

6. Post-Installation Support and Preventative Maintenance Plans

An HVAC system is a major investment—protect it with regular maintenance. Planz Heating & Air Conditioning offers commercial maintenance agreements that include:

• Bi-annual system tune-ups

• Filter replacements

• Emergency repair services

• System performance monitoring

Staying proactive reduces downtime, prevents costly repairs, and extends the life of your equipment.
