Our AC Repair Services in Buffalo Grove, IL
At AMZ Appliance Repair in Buffalo Grove, we handle all types of air conditioning problems – from minor component issues to complex system failures. Here’s what our certified HVAC technicians repair
AC Not Cooling or Blowing Warm Air
This is the most common AC complaint during a Buffalo Grove summer. If your air conditioner is running but only blowing warm or room-temperature air, the cause is often a refrigerant leak, dirty evaporator or condenser coils, or a malfunctioning compressor. Our technicians will pinpoint the exact problem and restore proper cooling output quickly.
AC Not Turning On
If your air conditioner won’t start at all, the issue may be a tripped circuit breaker, a blown fuse, a faulty thermostat, or a failed capacitor. We’ll systematically diagnose the root cause and get your system powered back up without delay.
AC Short Cycling (Turning On and Off Repeatedly)
An air conditioner that turns on and off too frequently – known as short cycling – puts excessive wear on the compressor and significantly reduces cooling efficiency. It’s commonly caused by a dirty air filter, low refrigerant, an oversized unit, or a faulty thermostat. We identify the underlying cause and fix it to restore steady, efficient operation.
Refrigerant Leak
Refrigerant is the lifeblood of your AC system – without the correct level, your unit cannot produce cold air. A refrigerant leak will cause your system to blow warm air, ice up, and run inefficiently. Our technicians are certified to safely locate the leak, repair it, and recharge the system to the correct level.
AC Frozen or Icing Up
Ice forming on your AC unit’s evaporator coils or refrigerant lines is a sign that something is restricting proper airflow or that refrigerant levels are low. Common causes include a clogged air filter, blocked return vents, or a refrigerant issue. We’ll diagnose the cause, thaw the system safely, and fix the underlying problem to prevent it from recurring.
Weak or Poor Airflow
If your AC is running but the airflow from your vents feels weak or uneven, the issue is often a clogged air filter, a failing blower motor, blocked ductwork, or a dirty evaporator coil. We clean, repair, or replace the relevant components to restore strong, consistent airflow throughout your home.
AC Making Unusual Noises
Banging, rattling, squealing, or grinding sounds from your air conditioner are always a warning sign. Banging may point to a loose or broken component inside the unit; squealing often signals a worn fan belt or motor bearing; grinding can indicate a failing compressor or motor. We locate the source of the noise and repair it before it leads to a more serious breakdown.
High Humidity Inside the Home
Your air conditioner doesn’t just cool your home – it also removes moisture from the air. If indoor humidity feels uncomfortably high even with the AC running, the system may be undersized, low on refrigerant, or have a failing evaporator coil. We’ll assess the system and restore proper dehumidification so your home feels genuinely comfortable.
Water Leaking from AC Unit
Water pooling around your indoor air handler is usually caused by a clogged condensate drain line, a frozen evaporator coil that’s thawing, or a cracked drain pan. Left unaddressed, a leak can cause water damage to your home. We’ll clear the blockage, replace damaged components, and ensure the condensate system is draining correctly.
Thermostat Issues
Sometimes what appears to be an AC problem is actually a thermostat issue. A miscalibrated, malfunctioning, or failing thermostat can cause the AC to short cycle, run continuously, or not respond to temperature settings at all. We test and calibrate your thermostat and replace it if necessary to restore proper system control.
AC Maintenance & Seasonal Tune-Ups
The best way to avoid a mid-summer AC breakdown in Buffalo Grove is a professional maintenance visit before the cooling season begins. Our annual tune-up includes a full system inspection, coil cleaning, refrigerant level check, electrical connection testing, filter replacement, and performance calibration – keeping your AC running efficiently and reliably all season long.

Our technicians work on most major AC brands installed in Buffalo Grove homes, including Rheem, Carrier, Lennox, Goodman, Daikin, Trane, American Standard, and Heil.

What Our Client Says
Overall Rating
4.8















































































Now I post a thumbs up for AMZ. Don’t hesitate to trust them!


















































Got it done and dusted


We would highly recommend.






















I recommend you give AMZ a call for appliance repair.
Stan and Dal helped repair a control board on my Dacor oven.



































Very recommend










Definitely will use them again






1 yr warranty on parts and labor
















He even refused to leave the house even though I told him to send me the invoice and I would pay. We finally had to pay to just get him to leave the house.
We spoke to the office manager who did not intervene and was only focused on getting paid.
I would give a zero star if it was an option. I do not recommend this service to anyone.











Marella O’Neil












Reached out and they were available to come the same day, that Saturday morning. Gave an arrival window and called when on the way.
Troubleshot, fixed and tested the solution all within that same window after confirming price. There was a $89 service fee, but it was deducted from final cost. Accepted Zelle which made payment easy.
For those wondering about the number of ratings, they do ask if you would provide Google feedback, but they do not pressure you or stand there making you feel like you must. They just offer you the QR code.
Good experience and nice to know they are insured and I would be lying if I didn’t say the Google guarantee did help me decide on who to reach out to. Thanks























































My dryer’s issue was “not heating “. He maintained it once like cleaning inside but my dryer doesn’t heat yet. He came to my house again and fixed it by replacing a coil.
Now, my dryer looks work well, he’s a really professional technician and great customer service. Of course, 2nd visit was for free, no additional charge for this trip.
His manager is also excellent, he arranged the technician on the day and I called and told the story it wasn’t fixed to him, he arranged the technician next day. Very quick work.


Many places ask for credit card info in advance but these guys take payment after work is done. That was important to me.
I have them in my contacts now. Definitely a company I would use again!
Thank you

Responded within 5 minutes to my inquiry. Answered my general questions on price and offered to be out the next day. As this wasn't an emergency, that was fine. Showed up in time range and identified the issue. Part was ready for install the next day and installed. Didn't fix the issue but actually showed the real issue, which was then fixed and I was only charged for the initial fix. I was pretty stunned by the fact they called me and said they would make it right since they diagnosed it incorrectly at first - that's top notch customer service. Part was installed an hour later and all fixed.
Happy with the speed and service of AMZ and very impressed with the customer service to make it right. Will recommend them to others.
Updating review: just had another issue so called them out. Tech was able to solve my issue in about 5 minutes, so had him give the fridge a maintenance tune up and clean the condenser and such so I could get value for my trip charge. Still keeping the 5 star rating - great group.

- FAQs
Have A Question On Your Mind?
The cost of AC repair in Buffalo Grove depends on the specific issue and the parts required. Common repairs like a capacitor replacement or a thermostat fix are relatively straightforward, while more involved jobs like a compressor repair or refrigerant recharge will cost more. At AMZ Appliance Repair, we always provide a clear, upfront quote before any work begins so there are no surprises.
The most common causes are a refrigerant leak, dirty evaporator or condenser coils, or a malfunctioning compressor. A clogged air filter can also restrict airflow enough to significantly reduce cooling performance. We recommend calling us to schedule a same-day AC repair so we can diagnose and fix the issue before it gets worse or causes further damage to the system.
This is called short cycling and is usually caused by a dirty air filter, low refrigerant levels, a faulty thermostat, or an oversized unit. Short cycling puts serious strain on the compressor and drives up energy costs. It's important to address it promptly - contact us and we'll diagnose the cause and restore stable, efficient operation.
Most air conditioner repairs are completed on the same day. Simple fixes like a capacitor replacement or thermostat repair can take under an hour. More involved repairs such as a coil cleaning or refrigerant recharge may take a few hours. Our technicians arrive prepared with commonly needed parts to minimize delays as much as possible.
If your AC is under 12–15 years old and the repair cost is less than half the price of a new unit, repair is almost always the smarter financial choice. For older systems that are breaking down repeatedly or running very inefficiently, replacement may offer better long-term value. Our technicians will give you an honest, straightforward assessment and never push you toward an unnecessary replacement.
