As a homeowner in Frankfort, IL, you know that home comfort is a year-round battle. It’s not just about surviving the winter with a strong furnace or the summer with a cold AC. It’s about the *entire system* working in harmony. Your home’s HVAC—Heating, Ventilation, and Air Conditioning—is an interconnected network. When one piece is out of sync, your comfort, air quality, and energy bills all suffer.
You don’t just need a furnace specialist or an AC technician; you need a true home comfort specialist. At Potocki Heating & Air Conditioning, we are Frankfort’s experts in complete residential HVAC repair. We look at the whole picture to find the true source of your problem. For a diagnostic that goes beyond the obvious, call our team at 815-693-5579 today.

Beyond “H” and “AC”: Why the “V” (Ventilation) is Key
Most homeowners only think about their HVAC system when the heat or air conditioning fails. But the “V” in HVAC—Ventilation—is the unsung hero (and often the secret culprit) of your home’s comfort. Your ductwork, blower motor, and vents are the lungs of your home. If your “lungs” are in poor shape, both your heating and cooling will struggle.
Our residential HVAC repair service goes beyond the furnace and the AC unit. We are experts at diagnosing how all three parts work together. A poorly designed or leaking duct system (a “V” problem) can make your AC (the “AC”) freeze up or your furnace (the “H”) overheat. A technician who only checks the AC unit will miss the real problem, leading to repeat service calls. We find the root cause.

Frankfort HVAC Repair: Your Questions Answered
What is the difference between HVAC repair and just furnace repair?
Furnace repair focuses on just one component: the “H” (Heating). A residential HVAC repair service, like ours, looks at the entire interconnected system: Heating, Ventilation, and Air Conditioning. This is crucial because a problem that *looks* like a furnace issue (e.g., poor heat) could actually be caused by a ventilation issue (e.g., bad ductwork).
My energy bills are really high. Can an HVAC repair help?
Absolutely. High energy bills are a classic symptom of a system that is struggling. This could be a dirty AC coil, an inefficiently burning furnace, or—very commonly—leaking ductwork that is sending your expensive heated or cooled air into your attic or crawlspace. A full HVAC diagnostic can pinpoint this waste, and the repair often pays for itself in energy savings, as noted by the U.S. Department of Energy.
Do you service all brands of HVAC equipment?
Yes. Our technicians are certified and trained to service all major makes and models of furnaces, air conditioners, heat pumps, and ventilation systems. Whether your system is 20 years old or 2 years old, we have the expertise to diagnose and repair it correctly.
