Fully Licensed & InsuredProfessional Air Conditioning Repair in Illinois
When your air conditioning quits in the middle of an Illinois summer, every hour without cool air matters. A+ HVAC and Refrigeration delivers fast, accurate air conditioning repair for homes and businesses, with most repairs completed the same day.
As a family-owned company serving Illinois since 2015, we hold ourselves to a higher standard of care than the big national chains. We work on central and ducted split systems, packaged rooftop units, and commercial cooling, and we take full responsibility for every job from the first phone call to the final test. That means honest, flat-rate pricing you approve up front, background-checked technicians who respect your property, and a full warranty on every repair we complete.
Whether you're a homeowner who needs comfort restored quickly or a business owner who can't afford downtime, our goal is the same: diagnose the real problem accurately, fix it right the first time, and leave your space clean. Most air conditioning repair jobs are completed the same day — and if a special-order part is required, we typically wrap up the very next day.
Signs You Need Air Conditioning Repair
Comfort problems rarely fix themselves, and small issues have a way of becoming expensive ones. If you notice any of the warning signs below, it's time to call our team at (312) 549-8885 before the problem gets worse:
- The system runs but the air isn't cold
- Weak or uneven airflow from the vents
- The unit short-cycles — turning on and off rapidly
- Warm air, ice on the coil, or water pooling around the indoor unit
- Grinding, buzzing, or clicking noises
- A sudden spike in your energy bill

Common Causes We Diagnose and Fix
Accurate air conditioning repair starts with an honest diagnosis. Rather than guessing or upselling, our technicians test the system methodically to find the true root cause, then explain exactly what's wrong and what it will cost before any work begins. Some of the most common issues we resolve include:
- Low refrigerant from a leak
- A failing compressor or capacitor
- A dirty or frozen evaporator coil
- A faulty thermostat or control board
- Clogged condensate drains
- Worn contactors and electrical connections
What's Included in Our Air Conditioning Repair
Every air conditioning repair visit follows the same methodical checklist, so nothing gets skipped because it wasn't the obvious symptom. Here's what the technician actually does on site:
- Measure refrigerant pressures and superheat/subcooling to confirm the actual charge
- Test the capacitor, contactor, and compressor windings under load
- Inspect the evaporator and condenser coils for restriction, fouling, or ice
- Verify thermostat calibration and control-board operation
- Clear the condensate drain and check the safety float switch
- Confirm the temperature split across the coil before we call the job done

What Air Conditioning Repair Costs
Most AC repairs land at our $199 labor minimum plus parts, with the final flat price set by the technician once the fault is confirmed — a capacitor swap and a compressor replacement are very different jobs, and you'll know which one you're facing before we start. Refrigerant is priced separately when a system needs to be recharged, and if we find a leak we'll tell you honestly whether sealing and recharging is worth it or whether you're putting money into a system near the end of its life.
Because we price per repair rather than by the hour, you know the total cost before we begin and there's no incentive for anyone to work slowly. Our diagnostic fee is $79 residential and $149 commercial, waived in full when you authorize the work during the same visit.
Preventing the Next Repair
Roughly half the emergency AC calls we run trace back to something a tune-up would have caught: a coil choked with dirt, a capacitor reading well below its rating, or a slow refrigerant leak that had been quietly killing efficiency for two summers. A spring tune-up is the cheapest insurance available against a July breakdown.
When our technician finishes, we'll give you an honest read on the overall condition of the system and whether routine maintenance would save you money — no pressure and no upselling, just straight advice about what we saw.
How Urgent Is This?
An AC failure during an Illinois heat wave is a genuine health risk for infants, older adults, and anyone with a respiratory condition — not just a comfort problem. Tell us if that describes your household and we'll prioritize your call. Our trucks carry the capacitors, contactors, and common motors that account for most failures, so the majority of AC repairs finish on the first visit.
Book online in under a minute or call us at (312) 549-8885. We'll give you a realistic arrival window and keep you updated — and if your situation is urgent, say so when you book.

Air Conditioning Repair — Frequently Asked Questions
How much does air conditioning repair cost?
We price per repair, not by the hour, so you approve a flat, upfront price before we start. Our diagnostic fee is $79 residential / $149 commercial and is waived in full when you proceed with the repair. Minimum labor is $199, with final pricing based on the complexity of the job.
My AC is leaking water inside. Is that an emergency?
It usually means a blocked condensate drain or a frozen evaporator coil, and while it isn't dangerous it can cause real water damage to ceilings and flooring. Turn the system off to let any ice melt, and book a visit — it's typically a straightforward fix once we're on site.
Do you offer same-day air conditioning repair?
Yes. The majority of our repairs are completed the same day as the service call. If a specialized, non-stock part is required, we typically finish the next day after it arrives.
Do you service window AC units or mini-splits?
Our air conditioning service covers central, ducted, and commercial systems only. We do not service window units or mini-split systems.
Is air conditioning repair backed by a warranty?
Absolutely. Every repair is backed by a full warranty — most replacement parts carry a 12-month warranty, and labor is warrantied 30+ days depending on the repair.
