Combined Services HVAC 756 Ridgeview Drive, McHenry, IL 60050

"They did a great job installing our multi zone furnace and ac in new construction. However their customer service and maintenance is not good. They are more expensive than other reputable HVAC companies and their scheduling for maintenance is a mess. I would use them to design and install but not for maintenance. I am moving to Ibbotson’s."

"Very knowledgeable, high quality work, very fast response time. they came out and replaced my whole A/C system and had me up and running before the heat wave. Highly recommend"

"Ed came out and walked us thru the process. And answered all of our questions. Trey and Carter were incredibly informative and did a fantastic job with the installation. I would highly recommend their service to anyone in need."

"Trey did an excellent job of installing a brand new AC & Furnace in my home! His professionalism and knowledge are/were very much appreciated. Would recommend Combined Services to anyone needing a new HVAC system...and especially if Trey is doing the instal!"

"Extremely professional. Mr Trey who attended to the request was extremely well versed in engineering, energy, heat transfer, and installation techniques that surpassed any other service person encountered before. Trey was meticulous in his approach, in his concern for the user’s convenience in terms of operating the system, mastery over piping and neatness in installing. Once completed, the installation looked perfect. His instructions to operate the system were equally professional. Looks like Trey has been very well trained in what he is doing and therefore is able to represent his company very well. More importantly Trey was extremely personable and willing to take all time needed to answer every question that I had, calmly and with patience. Thank you Trey for such a marvelous job."
