Heating and cooling services we handle
One call covers the whole system. We repair and replace furnaces, AC units, boilers, radiators, heat pumps and mini-splits, and we run seasonal tune-ups that catch small problems before they become emergency HVAC repair Chicago IL calls.
Furnace Repair
No heat, cold air from the vents, short cycling or a furnace that won't stay lit.
AC Repair
AC running but not cooling, warm air, ice on the lines or a unit that trips the breaker.
Boiler Repair
Boilers lose pressure, short cycle or quit firing entirely. We service Weil-McLain and Burnham units, test zone valves, circulator pumps and thermocouples, and purge air from hydronic lines.
Radiator Heat Repair
Steam radiator water hammer, cold radiators, leaking valves and uneven heat floor to floor.
Heat Pump Repair
Heat pumps that blow cold in heating mode, freeze up or fail to defrost. We test the reversing valve, defrost board and refrigerant charge, and repair or replace what's failed.
Emergency HVAC Service
No heat at 2 a.m., no cooling during a 95-degree weekend, or water pooling around the furnace.
Ductless Mini-Split Repair
Mini-splits that freeze up, leak water indoors, smell musty or stop responding. We clean coils and drain lines, check refrigerant charge with an electronic leak detector, and repair control boards.
Furnace Replacement
When repair no longer makes sense, we size the new furnace with an ACCA Manual J Load Calculation, not a guess.
AC Replacement
New AC sized right, matched to your existing ductwork and paired with R-410A or R-32 refrigerant equipment.
HVAC Tune-Up & Maintenance
A heating and air conditioning tune-up in Chicago IL twice a year keeps the system efficient and catches failures early.
How a service call works
No mystery, no waiting around all day. Here's the sequence from your first call to the moment your system is running again, whether it's a furnace repair Chicago North Side call or a full AC replacement in River North.

Call and describe it
Tell us what the system is doing. We ask a few questions, give you a realistic arrival window, and tell you what to check in the meantime, like whether the breaker tripped or the filter is clogged.

Diagnose and quote
The tech tests the system with the right instruments, shows you what failed, and hands you a written price before any work starts. You decide. No pressure and no sales games.

Repair and verify
We make the repair, then run the system through a full cycle. You'll see temperature rise or drop, amp draw and refrigerant pressures, so you know it's actually fixed and not just quiet for now.

Walkthrough and follow-up
Before we leave, we show you what we replaced, set the thermostat if needed, and note anything worth watching next season. If a part is under warranty, we handle the paperwork.

(312) 638-0812Most full system replacements in Chicago run $4,800 to $11,500 installed in 2026, depending on size, efficiency and whether ductwork needs work. A furnace-only replacement typically lands between $3,200 and $6,800. We size every job with an ACCA Manual J Load Calculation and quote the full scope before we order equipment.
The right company is the one that diagnoses before it sells. Look for NATE Certification, EPA Section 608 Universal Certification and a City of Chicago Mechanical Contractor License. Ask whether the diagnostic fee is credited toward the repair, and whether they stock common parts. We do all three, and you can call us at (312) 638-0812 to test it.
Yes. HVAC work in Chicago requires a City of Chicago Mechanical Contractor License, and refrigerant handling requires EPA Section 608 Universal Certification. Illinois also regulates contractor registration at the state level. Ask any contractor for their license before work starts, and verify it. We carry both and pull permits on replacements.
Carrier, Trane, Lennox, Rheem, Goodman, Bryant and American Standard all make equipment that holds up in Chicago's climate when it's sized and installed correctly. Installation quality matters more than the badge. We install AHRI Certified Equipment and match the system to your ductwork, which is where most reliability problems actually start.
Ask three things: are you licensed and insured, will you quote the job in writing before starting, and do you stock parts or schedule a return trip. A tech who shows up with a manifold gauge set, combustion analyzer and digital multimeter can diagnose on the first visit. If a company can't answer those questions clearly, keep calling.
