Furnace Repair

When your furnace fails in the middle of a Frankfort winter, the stress is immediate. Your home is cold, your family is uncomfortable, and you’re worried about a costly, complicated problem. In this situation, the last thing you need is a “quick fix” that doesn’t last, or a technician who just guesses at the problem. You need a fast, accurate diagnosis and a lasting, professional repair.

Potocki Heating & Air Conditioning is Frankfort’s expert in furnace repair. We specialize in meticulous diagnostics to find the *true* root cause of your heating problem, ensuring we fix it right the first time. For honest answers and reliable service, call our certified team at 815-693-5579.

Furnace Repair Frankfort, IL

The Critical Difference: A Guess vs. a Professional Diagnosis

Why is a proper diagnosis so important? Many furnace problems have overlapping symptoms. A furnace that’s short-cycling (turning on and off) could be a simple dirty filter, a faulty flame sensor, or a more serious issue with the control board. A technician who just guesses might replace the flame sensor, charge you for the part, and leave—only for the problem to return a day later.

Our furnace diagnostic process is different. We test the *entire* sequence of operations. We check the electrical components, test the sensors, and analyze the system’s performance to find the *one* component that is causing the failure. This process saves you money and time, eliminating the frustration of repeat service calls.

Honest Repair vs. Replace Consultation

If our diagnostic finds that your furnace is 15+ years old and requires an expensive repair, we’ll give you an honest consultation. We will clearly present the cost of the repair alongside the long-term benefits and savings of a new heating installation. We provide the data, but the decision is always yours, with zero pressure. This transparency is a core part of our service, aligning with U.S. Department of Energy guidelines on system replacement.

Upfront, Flat-Rate Pricing

We eliminate the anxiety of a running meter. Once our technician completes the furnace diagnostic, we will show you exactly what’s wrong and provide a clear, flat-rate price for the repair. You approve the full cost *before* we begin any work, so there are never any surprises or hidden fees.

Frequently Asked Questions About Heating Repair

How do I know if my furnace problem is an emergency?

Any total loss of heat when the outside temperature is near or below freezing is an emergency. The other critical emergency is the smell of gas. If you smell rotten eggs in your home, do not turn on any lights or appliances; leave the house immediately and call your gas utility provider from a safe distance. For non-gas related emergencies, heating safety is our top priority.

What is your service call fee?

We charge a diagnostic fee for the service call. This professional fee covers the cost of sending a certified, insured technician in a fully-stocked vehicle to your Frankfort home to perform a comprehensive, multi-point diagnostic on your complex system. In many cases, this fee is applied toward the cost of the repair if you choose to move forward.

Do you service all furnace brands?

Yes. Our technicians are trained and certified to service all major makes and models of furnaces, including Trane, Lennox, Carrier, Rheem, Goodman, Bryant, and more. Regardless of who installed it or how old it is, we have the expertise to diagnose and repair it.
