Heating & Cooling in Joliet
Joliet weather doesn't do gentle. January nights push below zero, July afternoons sit in the 90s with lake humidity, and the furnace or air conditioner in your house takes the beating. When it quits, you don't need a sales pitch — you need a technician who diagnoses the real problem, quotes the repair before touching a wrench, and gets your system running the same day.
That's what Joliet Heating & Cooling Pros does. We repair, tune up and replace furnaces, central air conditioners, boilers, heat pumps and ductless mini-splits across Joliet and Will County. Every make and model, every age of home — from the 1920s brick bungalows near downtown to the new construction along Route 59 and Caton Farm Road.
No heat, furnace short-cycling, blowing cold air, flame sensor and ignitor failures, cracked heat exchangers, thermostat problems. Emergency no-heat calls are prioritized.
AC not cooling, frozen evaporator coil, refrigerant leaks, failed capacitors and contactors, condenser fan motors, drain-line backups, units that run nonstop and never catch up.
High-efficiency furnace and AC replacement, spring and fall tune-ups, indoor air quality, and help claiming ComEd and Nicor Gas efficiency rebates.
Our Services
Gas and electric furnaces of every brand — Carrier, Lennox, Trane, Goodman, Rheem, Bryant, American Standard and more. We fix the fault, not just the symptom.
Central air conditioning repair with same-day service through the summer. We carry common capacitors, contactors and fan motors on the truck so most repairs finish in one visit.
Heat pumps, ductless mini-splits, rooftop units, zoning systems and smart thermostats. A full diagnostic with a written, flat-rate quote before any repair begins.
When repair no longer makes sense, we size and install high-efficiency systems that cut Nicor and ComEd bills — and we handle the rebate paperwork for you.
Joliet's older homes run on hot-water and steam boilers, and not every HVAC company will touch them. We service radiators, baseboard systems, circulator pumps and zone valves.
A fall furnace tune-up and a spring AC tune-up catch the failing part before it strands you at 2 a.m. in January. Priority scheduling and repair discounts for maintenance members.
How It Works
Tell us what the system is doing. No-heat and no-cool calls go to the top of the schedule.
You get a call when we're on the way. Shoe covers on, drop cloths down.
We find the actual fault and show you. You approve a written price before any work starts.
Trucks are stocked for the common failures. We test the full cycle before we leave.
Why Joliet Homeowners Call Us
A person picks up the phone at night and on weekends. No-heat calls in winter and no-cool calls for households with infants, seniors or medical needs are dispatched first.
You pay to find the problem or to fix it — not both. Every quote is flat-rate and in writing before work begins, so the price doesn't climb while the tech is in your basement.
If a $240 capacitor gets another five summers out of your AC, that's what we'll recommend. When replacement really is the better money, we'll show you the math.

Common Questions
The most common causes are a dirty flame sensor (the burners light, then shut off within seconds), a failed ignitor, a clogged filter that trips the high-limit switch, or a thermostat set to "fan on" instead of "auto." A dirty flame sensor is a quick, inexpensive fix; a cracked heat exchanger is not, and it's a carbon monoxide risk — if the furnace keeps shutting down, call rather than keep restarting it.
Most furnace repairs in the Joliet area land between $150 and $900 depending on the part. Flame sensors, ignitors and capacitors are on the low end; blower motors and control boards on the high end. We quote a flat rate in writing after the diagnostic, and the diagnostic fee is waived when you approve the repair.
A useful rule: multiply the repair cost by the system's age in years. If the result is over $5,000 — say a $600 repair on a 10-year-old unit — replacement usually wins, especially with current ComEd and Nicor efficiency rebates. Under that, repair. We'll run the numbers with you either way and won't push replacement when a repair is the smarter spend.
Usually low refrigerant from a leak, a frozen evaporator coil (often from a dirty filter or low airflow), a failing capacitor that keeps the compressor from starting properly, or a unit that was undersized for the house. On 90° Joliet days a healthy system should hold the thermostat setting; if it can't, something is wrong and it's costing you on the ComEd bill.
Yes — 24 hours a day, 7 days a week, including holidays. No-heat calls in winter are treated as emergencies. There is a modest after-hours premium, quoted up front when you call.
Once a year, ideally in early fall before the first cold snap. An annual tune-up keeps the manufacturer's warranty valid, catches worn parts before they fail, and includes a carbon monoxide safety test. Air conditioners get the same treatment each spring.
Yes. The City of Joliet requires a mechanical permit for furnace, boiler and air-conditioner replacement, and the work must be done by a contractor registered with the city. We pull the permit and schedule the inspection as part of every installation.
