Hear from Our Great Customers in Crystal Lake and McHenry

The technician had to make two visits to my house that day to fix the “big” problem that was not very east to fine. He was professional, very courteous and friendly, and he was working very hard to get my furnace back in working order. I will definitely continue to use McHenry HVAC and I will always recommend them to my friends and family when they need HVAC services. I know times are tough right now and I really hope McHenry HVAC makes it through this economic crises.

Matt & Company are the BEST. I manage a commercial construction company and I know a quality residential operation. The people at McHenry Heating & Air are THE reason I have a Trane system in my home.

Matt & Jodie, Cary


I will recommend them to neighbors with confidence. Everything exceeded our expectations.

I had a very good experience with McHenry Heating and Air. Initially, it started with an emergency service call in the middle of winter because my old furnace broke down. The technician came out to my house promptly and was very helpful. He seemed like he genuinely cared about helping me out and getting my system back up and running. Unfortunately, he was only able to give it a temporary fix. However, after quoting me a figure of several hundred dollars to order the part and have it fixed the next day, the technician was kind enough to offer some very valuable advice: it might be worth it to look into buying a new furnace altogether rather than putting $500 into an 18-yr-old one. I was hesitant to even start that conversation, not only because I didn't have the money for a new furnace, but also because my old one needed immediate next-day repair - I didn't have the time to wait for a new furnace to arrive and be installed. The temp fix could break and my pipes could freeze by then! However, despite it being nearly midnight, the technician took the time to inform me on a number of different options for a new furnace, and quoted me fair and upfront prices. And he didn't try to upsell me to a fancy system I didn't need. Then, he made a call to the owner of the business to see if a next-day installation would be possible for the new furnace (by this time, it's after midnight mind you). The owner's response? "If the customer needs a new furnace tomorrow, we'll find a way to fit him in tomorrow and get it installed." A new furnace was not something I had built into my budget; however, he offered a decent price on a name-brand Trane system that would also save me money on my gas bills. The special rate of 0% APR with 24 Equal Monthly Payments, along with the 5-yr labor, 10-yr parts warranty really sold me. So I agreed to purchase a new one. And sure enough, the installation crew came to my house and installed the new furnace the very next day. And they were all very friendly, knowledgeable, cleanly, and courteous. Again, I felt like they truly cared about me as a customer. They cleaned up after themselves, hauled the old unit away, and explained everything I needed to know about the new unit. And the total amount owed came to exactly what I was originally quoted. Great all around job by McHenry Heating and Air, and fantastic customer service. I would definitely recommend to others.

I just wanted to say thank you for the incredible service experience. Coming home after a long trip to a broken water heater is an awful feeling, especially when all you want is a hot shower. I don’t know how you did it, but your service professionals, John & PJ, were at our house within 30 minutes of my initial contact. They were polite, professional and had the problem diagnosed and fixed in under 30 minutes. I can’t thank you enough for a great experience. I will certainly recommend you to everyone I know.

McHenry Heating & Air – It’s the BEST!! I love my furnace and will get to love my AC when the summer heats up.

Marcia, Richmond


We have used McHenry Heating & Air since we moved into our house. They put in our Trane furnace first which was a very good experience. When we wanted to change our 20+ year old AC we thought of no one else but McHenry Heating & Air. For the 5 years we have lived in this house they are our only choice. Great service! Great employees! Great products!

Anita, McHenry


McHenry Heating & Air is BY FAR the best contactor I have ever had!!

Dennis, Lake Villa


John arrived promptly; his appearance was very clean and neat. He went to work immediately; he had his tools and instruments well organized. Performed the AC clean and check and answered our questions with expert knowledge. We spoke to John about the new tools and instruments he had and he said McHenry Heating & Air is very diligent in keeping service technicians well trained with classes and seminars though out the year and supplying them with high tech instruments for more efficiently servicing customer’s equipment.

Mark & Sharon, Johnsburg


McHenry Heating far exceeded my expectations and their whole team impresses me again and again. True professionals with a real one on one feel that not just me, but anyone in the community can lean and improve their lives and health by a true seamless match between Trane & McHenry Heating. If all companies saw how McHenry Heating ran their team I’m sure they too would look up to them. Furnace works great and my breathing problems are becoming an old memory. Thank you Trane for sharing your team with McHenry Heating’s team. This has allowed me to get the best of the best in not only my house but my community.
