Your home’s heating and cooling system is the most complex, expensive, and critical appliance you own. It’s connected to your electrical panel, your gas line, and the very air your family breathes. When you need service, hiring the cheapest “handyman” or an unverified contractor is a massive gamble, one that can put your Orland Park home at risk of safety hazards, voided warranties, and catastrophic secondary damage.
This is why choosing a professional is non-negotiable. Potocki Heating & Air Conditioning is a team of fully licensed HVAC contractors serving the Orland Park, IL, community. We provide a guarantee of safety, accountability, and expertise that only a true, credentialed professional can offer. Protect your home and your peace of mind by calling the proven experts at 815-693-5579.

The Potocki Guarantee: Licensed, Insured & Certified for Orland Park
When you hire Potocki Heating & Air Conditioning, you are not just hiring a technician; you are partnering with a professional, fully-vetted business. Our credentials are your protection.
We Are Fully Licensed
A state-issued HVAC license is the baseline for professionalism. It proves we have passed rigorous testing on heating, cooling, and refrigeration systems, and that we are registered and recognized as a legitimate operator. We are fully compliant with all Illinois and Orland Park municipal codes, ensuring your work is done safely and correctly.
We Are Fully Insured
This is one of the most critical protections for you as a homeowner. What happens if a technician is accidentally injured on your property? What if a mistake causes a water leak or an electrical short? Because we carry comprehensive liability and worker’s compensation insurance, *we* are responsible, not you. Hiring an uninsured contractor can make you personally liable for damages and injuries.
We Are Certified Experts
While a license is the law, we go a step further. Our technicians pursue ongoing training and certifications (like NATE-certification, for example) to stay on top of the industry’s latest technology. This ensures that the certified HVAC technician who arrives at your Orland Park home knows how to service your high-efficiency system as expertly as an older model.
Why Hiring a Licensed Contractor is Your Only Safe Choice
Some homeowners are tempted to save a few dollars by hiring an unlicensed individual. The potential costs of this decision, however, are catastrophically high. Here is what our license *really* means for you.
- It Protects Your Family’s Safety. An improperly installed or repaired furnace can leak deadly carbon monoxide (CO) or create a serious fire hazard. Our license is your assurance that we understand the critical science of combustion, ventilation, and electrical safety.
- It Upholds Your Manufacturer’s Warranty. This is a crucial, often-overlooked fact. Virtually *all* HVAC manufacturers will void your expensive parts warranty if they discover that an unlicensed person has performed service or installation on the unit.
- It Guarantees Accountability. As a licensed and local Orland Park-area business, we have a reputation to protect. We have a physical address, a public record, and a long-term commitment to our clients. We stand behind our work.
Don’t take an unnecessary risk with your home’s most important system. For a guaranteed safe and professional service, call the licensed HVAC contractors at Potocki Heating & Air Conditioning. Schedule your service by calling 815-693-5579 or contacting us online.

Frequently Asked Questions About Hiring a Contractor in Orland Park
How can I check if an HVAC contractor is licensed in Illinois?
This is a smart step for any homeowner. You can verify many professional licenses through the Illinois Department of Financial and Professional Regulation (IDFPR) website. A reputable contractor, like Potocki, will also be able to provide you with their license number and proof of insurance upon request. If a contractor is hesitant or cannot provide these, consider it a major red flag.
What are the warning signs of an unlicensed contractor?
Be wary of a few common warning signs. These include:
- They ask for the full payment in cash, upfront.
- They cannot provide a license number or proof of insurance.
- Their business vehicle is unmarked, or they use a personal cell phone with no business listing.
- Their price is “too good to be true,” often because they are cutting corners on insurance, parts, and permits.
For more tips on avoiding scams, you can check resources from the Better Business Bureau.
Is there a difference between a “licensed” and “certified” HVAC technician?
Yes, and it’s an important distinction. “Licensed” means the contractor (the business) has met the legal requirements set by the state of Illinois to operate. “Certified” typically refers to an individual technician’s advanced, optional training from an industry body (like NATE) or a specific manufacturer. At Potocki, we are a licensed contractor, and we employ certified technicians to ensure you get the highest level of expertise, a standard recommended by Energy.gov.
