All Service Heating & Air Conditioning, Inc. 900 Vincent Drive, Sandwich, IL 60548

"This is by far the best company in this field that I have worked with. They are honest in their assessments and in the work they do. Everyone we dealt with was an absolute professional from start to finish. They performed tasks quickly and cleaned up afterwards. I can’t say enough about how happy we are with this company. I have recommended them to family, friends, and to anyone reading this."

"Astronomical service. Called to have the furnace serviced as the motor went. Prompt response and repair. The gentleman Jamie I believe his name was (sorry if it’s misspelled). Very kind did an excellent job. Would recommend to family and friends for sure!!"

"Best service and reasonably priced for a new boiler. Everyone at All Service was amazing to deal with. I will definitely do business with you guys again. Thank you!!!"

"I had my furnace serviced by another company and was told I needed to replace it because the heat exchanger was cracked. I called Jamie for a second opinion, and he confirmed that it was not cracked, and I didn’t need a new furnace. I knew from the way he spoke to me I could trust him. He has saved me thousands of dollars, and I am thankful that I met him. Take it from me, you will be very happy you called them."

"My furnace wouldn't kick on during these cold nights. I own a modular home which a lot of companies won't work on.I called the office and spoke with Melissa. She was very helpful and put me on the schedule for today. Jamie came out and within a hour or so he had the problem resolved. Jamie was very professional and showed me everything he did and told me what I can do if the furnace quits again. There will be several parts that I will need and he is going to get the cost and let me know asap. I couldn't be happier with All Service Heating. I will highly recommend to everyone! Thank you Jamie and Melissa for your help."
