GREEN HVAC SOLUTIONS INCORPORATED — Zero Handoffs. One Team. Every Time.
Green HVAC Solutions Incorporated is a locally rooted energy-efficient HVAC and green building systems contractor based in Chicago, Illinois. Founded in 2010 by environmental engineer and longtime neighborhood resident Elena Vasquez, the company has built its reputation not only on high-performance, eco-conscious installations but also on directly supporting local youth through mentorship and technical education. Since 2015, they’ve partnered with local high schools to host an annual "HVAC Youth Workshop," where students learn basic system diagnostics, safety protocols, and sustainable energy practices — all while gaining real-world experience in the field.
Frequently asked
Our team specializes in energy-efficient retrofits and controls upgrades that help reduce energy consumption while maintaining optimal comfort. We install smart-thermostat retrofit kits, perform duct-sealing using aerosol injection rigs, upgrade to variable-frequency-drive retrofit panels, and service energy-recovery ventilator units with our portable service cart. These targeted upgrades are designed to improve system performance, lower utility bills, and enhance indoor air quality.
We understand that no-heat or no-cool situations can be urgent, so we offer a dedicated 24/7 emergency line for immediate assistance. If your system fails during weekends, holidays, or after normal business hours, you can call our emergency service and our team will respond promptly to restore comfort to your space. Regular business hours are Monday through Friday from 7am to 5pm.
The timeline varies depending on the scope of work and system complexity, but most of our energy-recovery ventilator services and smart-thermostat installations can be completed within one to two days. Larger projects such as duct-sealing with aerosol injection or full variable-frequency-drive retrofits may take up to a week. We always provide detailed project timelines during the initial consultation and keep customers informed throughout each phase.
We use industry-standard tools and methods to track and verify performance gains. After installing smart-thermostat retrofit kits, we perform system diagnostics to confirm proper operation and calculate potential savings based on actual usage data. For duct-sealing projects using aerosol injection rigs, we conduct post-treatment testing to measure airflow improvements and leakage reduction. Our team also provides a detailed report showing energy consumption trends before and after upgrades, giving you clear visibility into your investment's return.
