When your furnace or air conditioner fails in your Tinley Park home, it’s tempting to find the cheapest, fastest fix. You might get a “promise” from a handyman or an unlisted contractor that they can save you money. But when it comes to a complex system involving gas lines, high-voltage electricity, and your family’s safety, a promise isn’t enough. You need verifiable proof.
At Potocki Heating & Air Conditioning, we are the licensed HVAC contractors Tinley Park residents trust because we provide that proof. Our license is your guarantee of our expertise, our insurance, and our accountability. Don’t risk your home on a promise; get guaranteed peace of mind from a proven professional.

What Does Our HVAC License “Prove” to You?
The term “licensed” is the most important word you can look for when hiring an HVAC professional. It’s not just a word; it’s a legal and financial shield for you, the homeowner. Here is what our license *proves* to every client in Tinley Park.
1. Proof of Financial Protection (Insurance)
This is the most critical protection for your finances. A licensed HVAC contractor is required to carry full insurance. This includes:
- Liability Insurance: If we accidentally damage your property (e.g., a water leak, a damaged wall), our insurance pays for it, not you.
- Worker’s Compensation: If a technician is injured on your property, our insurance covers them.
If you hire an uninsured contractor, *you* become the general contractor. If they get hurt, you could be liable. If they damage your home, your homeowner’s insurance may deny the claim. Our license is proof that you are fully protected from all liability.
2. Proof of Technical Expertise (Testing)
An HVAC license isn’t a participation award. It is *proof* that we have passed rigorous, state-mandated exams on the complex systems we service. This includes proven knowledge of:
- Safe handling of natural gas and combustion systems.
- Correct high-voltage electrical wiring.
- Refrigerant handling and EPA regulations.
- Tinley Park and Illinois state building codes.
This proof means you are getting an expert who knows how to do the job safely and correctly, not someone who is learning on your expensive equipment.
3. Proof of Warranty Validity
This is the hidden financial trap of hiring an amateur. Read the fine print on your furnace or AC warranty. *All* major manufacturers (Trane, Lennox, Carrier, etc.) state that the warranty is void if installation or service is performed by an unlicensed person. That “cheap” repair from a handyman could cost you thousands by voiding the warranty on a part that should have been covered for free.

Frequently Asked Questions About HVAC Contractors
What is the difference between “licensed,” “insured,” and “bonded”?
This is an excellent question. They are all forms of protection for you:
- Licensed: This is *legal permission* from the state of Illinois. It proves the contractor has passed exams and is registered to perform HVAC work.
- Insured: This is *financial protection* for you. It’s an insurance policy that covers accidents, property damage, and injuries.
- Bonded: This is a *financial guarantee*. A bond is a type of insurance that protects you if the contractor fails to complete the job, doesn’t pay for permits, or commits theft.
A true professional, like Potocki, will be fully licensed and insured.
Can’t I just hire a “good handyman” for a simple HVAC repair?
It’s tempting, but it is a major risk. First, as we mentioned, you will almost certainly void your manufacturer’s warranty. Second, there are few “simple” HVAC repairs. Even a “simple” thermostat replacement involves low and high-voltage wiring, and a mistake can fry your entire system’s control board. A mistake with a gas line or a flue pipe is a life-safety hazard. It’s never worth the risk.
How can I verify a contractor’s license in Tinley Park?
You can (and should) verify any Illinois professional license by visiting the Illinois Department of Financial and Professional Regulation (IDFPR) website. You can also check for a long-standing positive reputation with groups like the Better Business Bureau (BBB). A professional contractor will always be transparent and provide their license number upon request.
