Allied Air Conditioning & Heating Corporation - Palatine

I have used Allied for many years, both at home and at work. They have always provided outstanding service and responsiveness. I highly recommend them.

I was very happy with the service I received from Bill. He is very professional. He is friendly and knows what he is doing. He goes the extra mile. I will always ask for him.

I had hope that after many calls and talk someone from this company can really help me with estimate and preparation of install AC Carrier.
Nothing...I lost my time and energy.

Purchased my HVAC unit from Allied nine years ago, and use them to service the unit.
Allied has, time after time, delivered nothing but EXCELLENCE.

Great service and clean up when done. Chris was very professional, explained all work being preformed and very polite. Will can again for AC service in spring.

As always, prompt, personal and professional! I have referred to my clients with confidence as well ~ they are my "go to" HVAC service company!

Great tech, got new ac with lots of info on how to choose one at our price point for our home, and a great new thermostat. Great service and prices!

The periodic check up went very satisfactory. Chris, the tech, was punctual, very personable and informative. All systems go!

Great service! Answered all my questions and was very polite.

Chris was the technician who attended my house. He did a thorough check and figured the problem very quickly.
