Common problems
Signs your AC needs repair
If you notice any of these, call us before a small problem turns into a breakdown on the hottest day of the year.
Blowing warm air
The AC runs but the air from the vents isn't cold.
Won't turn on
The thermostat calls for cooling but the outdoor unit stays quiet.
Ice on the lines or coil
Frozen refrigerant lines usually mean low refrigerant or an airflow problem.
Water leaking inside
A clogged condensate drain can flood the floor around your furnace.
Strange noises
Buzzing, clicking, grinding or a fan that won't spin.
Higher electric bills
A struggling AC runs longer and uses more power to keep up.

Reviews
What homeowners say
Our tech was knowledgeable, prompt, thorough, and generous with his time and skill. We had an AC unit that was flooding into our den, and the issue was solved in less than 2 hours. I'd give 6 stars if I could!
AQC Services in Schaumburg was outstanding from start to finish. They responded quickly, communicated clearly, and provided straightforward pricing with no games. They arrived on time and were able to repair my A/C the same week.
We've had Ross out twice now in the past couple years, and have had wonderful experiences both times. He and AQC are reliable, trustworthy, and responsible! We will call AQC for all needs in the future.

Why is my AC blowing warm air?
Common causes are a failed capacitor, a dirty or frozen coil, low refrigerant from a leak, or a tripped breaker. A clogged filter can also choke airflow. Check the filter and breaker first, then call us if it's still warm.
Why is water leaking near my furnace?
In summer, that's usually the AC's condensate drain or pump. When it clogs, water backs up and overflows. We clear the drain, check the pump and make sure it doesn't happen again.
Should I repair or replace my AC?
If your AC is newer and the repair is minor, repairing usually makes sense. If it's older, uses an outdated refrigerant like R-22, or needs a major part like a compressor, replacement can save money over time. We'll walk you through both options honestly.
