Allied Air Conditioning & Heating Corporation - Palatine

Very knowledgeable & pleasant to work with. Service call/estimator Chris was amazing. A bit pricey, supposedly due to busy season.

I've used Allied Air Conditioning & Heating for a number of years and always had a positive experience. Their invoices are well documented in terms of work performed and they also verbally explain what did and found before they leave. Happy to continue using them.

Steve, the technician on duty after hours is awesome, very helpful, very knowledgeable.... 👍👍👍Got us through on Thursday night the 22nd December, during one of the coldest, windiest nights, this year. TY very much Steve and your company...,,🙏🙏🙏

Kevin in sales was incredibly knowledgeable and helpful during my initial meeting. He walked me through the process and what to expect when the install specialists arrived. The install specialist was prompt, clean, and extremely knowledgeable. The entire process of replacing my furnace, humidifier, and thermostat was without issue. The team did a great job. Highly recommended!

Our serviceman was very knowledgeable and pleasant. The best serviceman we have had in a long time. Would definetly use Allied again.

Cannot recommend this place enough. Friendly helpful staff and they even helped me troubleshoot something over the phone in an emergency once. Going here you will get the job done correct the first time without a doubt

I would definitely recommend this company to my friends. They are represented very well by their employees.

Excellent installation. Technician was on time, friendly and explained the new equipment after installation. Would recommend Allied for any HVAC needs.

Honesty is the best policy. And Allied subscribes to this policy. 30 year old furnace stopped working and all it needed was a part to be cleaned. Didn't try to sell us a new unit when we didn't need it. Just good honest work.

My HOA required yearly cleaning and inspections on my HVAC system and Allied seemed like the perfect fit for the job. Tina and Jamie were very helpful over the phone. They helped answer my questions and were able to get me scheduled in a window that works best for my schedule. Chris L was sent out to my property. He was professional, knowledgeable, and polite. He was able to show me where safety issues were present and was able to get me in contact with someone who could give me replacement costs in the same day. Pat came out to do some estimates and was also professional, knowledgeable, and polite. Even around pets, the entire Allied team has displayed great care and professionalism.
