What We Believe About the Customer Experience

A great HVAC contractor does more than fix equipment — they partner with customers to improve comfort, reduce energy costs, and provide predictable system performance. We believe the customer experience should include:

  • Clear communication: We explain what we will do, why, and how it impacts your home or business.
  • Respect for your space: We use floor protection, clean up after work, and leave your property as tidy as we found it.
  • Documentation: Every major service or installation includes a written report, parts list, and operational guidance.
  • Follow-up: After installations and significant repairs, we check back to ensure everything is running as expected.

Our Technicians & Training

Each Maci Mechanical technician undergoes rigorous training in service diagnostics, installation techniques, code compliance, and safety procedures. We focus on problem-solving skills so technicians can identify root causes — not just symptoms — and propose solutions that balance upfront cost with lifetime value.

We maintain certifications relevant to HVAC work, refrigerant handling, and specific manufacturer credentials for Trane and Goodman equipment. Constant training ensures technicians can install and service advanced systems like variable-speed equipment, heat pumps, and energy recovery ventilation (ERV) units.

Community & Local Commitment

Being a local contractor means more than geography — it means investing in the community. We support local suppliers and contractors and prioritize hiring and training within the region. We’re familiar with Tinley Park’s building types, typical insulation levels, and energy usage patterns, which helps us provide solutions optimized for real-world conditions.

Safety & Compliance

Safety is central to everything we do. For furnaces and combustion appliances, we test for carbon monoxide, check venting systems, and confirm safe operation. For electrical connections and starters, we ensure proper wire sizing and protective devices. Our installations comply with local building codes, and we obtain necessary permits on behalf of customers when required.

How We Work With You

We can calculate expected energy savings and discuss available rebates or incentives.
