OUR FURNACE REPAIR SERVICES & COMMON PROBLEMS WE FIX
At AMZ Appliance Repair in Buffalo Grove, we handle all types of furnace problems – from quick fixes to complex component failures. Here’s what our certified HVAC technicians repair:
Furnace Not Heating or No Heat at All
This is the most critical furnace failure, especially during a Buffalo Grove winter. If your furnace is running but producing little or no heat, the problem is often a faulty ignitor, a malfunctioning gas valve, dirty burners, or a tripped limit switch. Our technicians will diagnose the exact cause and restore full heating output quickly.
Furnace Not Turning On
If your furnace won’t start at all, the issue may be as simple as a tripped circuit breaker or a thermostat misconfiguration, or as complex as a failed control board or a broken ignition system. We’ll work through the diagnosis systematically and get your furnace firing again without delay.
Furnace Short Cycling (Turning On and Off Repeatedly)
A furnace that turns on and off too frequently – known as short cycling – is one of the more common heating complaints. It’s typically caused by a clogged air filter restricting airflow, an overheating heat exchanger, a faulty flame sensor, or a malfunctioning thermostat. Left unaddressed, short cycling puts excessive wear on your system and drives up energy bills.
Cracked or Damaged Heat Exchanger
A cracked heat exchanger is a serious safety issue – it can allow carbon monoxide to leak into your living space. If you notice soot around the furnace, a yellow or flickering burner flame, or unexplained illness symptoms in your household, call us immediately. Our technicians are trained to inspect, diagnose, and safely address heat exchanger issues.
Blower Motor Failure
The blower motor is responsible for circulating heated air throughout your home. A worn-out or failed blower motor results in weak or no airflow from your vents, even when the furnace is running. We repair and replace faulty blower motors to restore proper air distribution across every room.
Ignitor & Pilot Light Issues
On modern furnaces, a failed hot surface ignitor is one of the most frequent causes of a furnace not lighting. On older systems, a faulty pilot light or thermocouple may be the culprit. Both are repairs our technicians carry out regularly and can typically fix in a single visit.
Flame Sensor Problems
A dirty or faulty flame sensor will cause your furnace to light and then shut off within seconds, as the sensor can’t confirm the burner is producing a stable flame. This is a very common furnace issue during the heating season. We clean or replace the flame sensor to restore reliable furnace ignition.
Inducer Motor Failure
The inducer motor pulls combustion gases through the heat exchanger and vents them safely out of your home. A failing inducer motor can trigger pressure switch errors and prevent the furnace from completing its startup cycle. We diagnose and replace faulty inducer motors to restore safe, proper furnace operation.
Unusual Noises from the Furnace
Banging, squealing, rattling, or rumbling sounds from your furnace are never normal. Banging may indicate delayed ignition or a loose component; squealing often points to a worn blower belt or motor bearing; rattling can signal loose panels or ductwork. We identify the source of the noise and fix it before it leads to a more costly breakdown.
High Energy Bills from an Inefficient Furnace
A furnace that’s working harder than it should – due to dirty filters, restricted airflow, or worn components – will consume significantly more energy and drive up your heating bills. We perform a thorough diagnostic to identify what’s causing the inefficiency and restore your furnace to peak performance.
Furnace Maintenance & Annual Tune-Ups
The best way to avoid a costly furnace breakdown during a Buffalo Grove winter is regular maintenance. Our annual tune-up service includes a full safety inspection, burner cleaning, ignitor testing, filter replacement, heat exchanger check, and system calibration – everything needed to keep your furnace running safely and efficiently all season long.

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 furnace repair in Buffalo Grove depends on the specific issue and the parts required. Minor repairs like a flame sensor cleaning or ignitor replacement are typically straightforward, while more complex issues like a blower motor or control board replacement will cost more. At AMZ Appliance Repair, we always provide a clear, upfront quote before any work begins.
This is called short cycling and is usually caused by a clogged air filter restricting airflow, a dirty or faulty flame sensor, an overheating heat exchanger, or a thermostat issue. It's important to address furnace short cycling quickly, as it puts unnecessary wear on your system and significantly increases your heating costs. Contact us to schedule a diagnostic visit.
If your furnace is producing little heat, making unusual noises, short cycling, or showing a sudden spike in your energy bills, it likely needs a furnace repair in Buffalo Grove. A tune-up, on the other hand, is a preventative service for a furnace that's still running but may benefit from cleaning, calibration, and an overall health check. When in doubt, give us a call and we'll diagnose it for you.
Most furnace repairs are completed on the same day. Simple fixes like replacing an ignitor or cleaning a flame sensor can be done in under an hour. More involved repairs such as a blower motor or inducer motor replacement may take a few hours. Our technicians arrive prepared with commonly needed parts to minimize any delays.
If your furnace is under 15 years old and the repair cost is less than half the price of a new unit, repair is almost always the better option. For older systems that are breaking down repeatedly or running very inefficiently, replacement may make more financial sense long term. Our technicians will give you an honest, straightforward assessment and never push you toward an unnecessary replacement.
