Their service technicians are well trained and professional in their service delivery. Last night our air conditioner stopped working, I called and left a message requesting assistance and the very next morning (a Saturday) they returned our call and scheduled Tyler H. To come to fix our air conditioner the very same day. Tyler H. Arrived early and quickly repaired the issue. He was so knowledgeable, kind and professional and answered all our questions. So fortunate to have Heritage Heating and Cooling and their quick response to help us in this scorching heat, and on a weekend!! Thank you so much for always being there for us!!

Since It had been less than 90 days then that leak belonged to him or the manufacturer. I surely didn't cause it but Im surely being charged for it. Im elderly and on a fixed income and haven't had central air in my home all summer. He take no pride in his work. It's all about the dollars to him. He knows that I should not be paying for a coil leak. No other company with take the job using the manufacturer warranty. He could have did the leak test last summer and submitted documents to Goodman Customer Service Warranty Dept and got the problem solved but he wasn't any help even though he got paid to install the unit.

King did a fantastic job with our new HVAC system. We are all electric with a heat pump and I was…read moreconcerned about how all that would go. We had a very old system and desperately needed the upgrade. Every single part of our experience was seamless, professional, and excellent! We called on a Friday and we had a crew working the next week, completing the process in just two days. From the start of working with King, it was easy! John D. came to our home, explaining what we had, what was needed and what options we had to get the most from our hvac system. He was polite, professional and very informative. He wasn't just selling stuff to sell it, he really gave us confidence from the start, knowing his information and being able to explain the options and different brands and systems to us. We were even able to get a new filter system that only needs changed once a year to save on replacement costs. We also now have a working humidifier system too! Then meeting the install pros, like Mike W. He continued to add to my confidence in King Heating and Cooling. He came in very friendly introducing himself and his crew (he did this any time a new tech would come out), explaining what would happen, answering questions I had going into the install day, and was very respectful of my property (asking where they could park, laying down protective sheets to cover flooring & stairs and they all wore booties over their boots to make sure and show the upmost respect and politeness). I appreciated that and actually didn't even expect that! I also was grateful of how John D came to make sure all was going well on the job. What company do you know of that provides this type of quality assurance, none that I know! King is different, they're not only experienced, but they go above and beyond for their customers! Mike W made sure to help set up our new thermostat and walked me through the app process and answered all questions. The whole experience was exceptional! It's a huge purchase and you want to have confidence that every part of the process is smooth. King knows just how to do that. They have a very kind office staff that welcomes you in and creates a pleasant phone experience too. They also provide updates any time your technician is coming out, sending you a text with their picture and a bio about them. I loved that. Taking extra safety precautions like this is important in our world today. I'm so happy we went with King Heating and Cooling! We'd recommend them to everyone! From start to finish, you will be taken care of with professionalism, expertise and excellence!

That's how we found out about Craig-Air, as they were the recommended local provider by them. We haven't always had the best customer service from our warranty management, but most of their contracted providers, once engaged, have been good. Craig was way better than good. We got a call from them first thing in the morning after the home warranty verification, saying they could be right out. We asked "how soon was that"...the technician, Mark, said "ten minutes". He was there in EIGHT. He quickly diagnosed the problem, replaced a part, and then explained to us what had happened and how it caused the water leakage, in layman's terms we understood just fine, and was in and out. I really appreciate the speedy service, the quality and efficiency of the work, the courtesy, but most especially, I appreciate the value added of Mark explaining to me the process and remedy without talking down to me as a non-mechanic homeowner. He didn't have to do that, even though it was only a few more minutes of his time. A company with professionals like Mark is a company I want to recommend. I'm including a picture of their business card he left!

I have a Sears Warranty Program Contract, and after having two no-contacts from D AND S HEATING AND COOLING (No word from in almost 72 hours) and Malherek's Heating and Cooling who just failed to answer their phone, even after telling the Sear Service Rep they would get to me and resolve my heating issue. How do they stay in business when treating customers like this in beyond me. In any event Craig as was contacted by a Sear Warranty Rep and immediately stepped up in response. Jenny from Craig made it clear that I should contact her ASAP so as to find out what was going on. I did so at the suggestion of the Sear Warranty Rep, and the rest was a major surprise. Jenny told me that might be able to get a serviceman out in a few hours, but that it could be the next morning. Fine by me since I have been waiting 3 days to hear from anyone at D AND S Heating and Cooling to no avail (two phone calls and two voice mails later). They were actually able to get a serviceman out that day. He was very very professional, and did a quick job at assessing the problem with my furnace. Within and hour I was back to having heat once more. I want to say thanks to Craig-Air for being about the business of Heating and Cooling. They made me have some confidence in the fact that there are a reputable HVAC service in the area that cares enough to quickly contact a possible client. Side joke of sorts: After the rep from Craig-Air had restored my heating and been gone about 15 mins. I get a call from D AND S asking if I need someone to come out. I basically told him already taken care of (No thanks to his company). Their excuse for no call backs: My number showed up as SPAM. Not sure how but I ask them did they ever bother to listen to the voicemails I left...Basically a BIG NO as he didn't even bother to check!....AGAIN, WHY IS THIS PLACE in Business?...DAys LATE and dollars short at that point. I'll never use D&S HVAC to work on anything. Anyway if you guys need HVAC work and lots of other stuff done..See Craig-Air in Troy, Illinois @ 618-624-8722 and let them give you a quote as well.

It was time to replace a 30 year old system. The moment I opened the front door and met Tyler Koonce, I relaxed and realized I was in very good hands. I can't say enough good things about Tyler. He's mature, professional, knowledgeable, an incredibly hard worker, and just a nice person. Tyler explained everything that would occur that day and encouraged me to check in on the progress at any time and ask questions, which I did. His colleague Chris joined him and the two of them spent the next five hours installing the new Lennox system. The two of them did a great job and were a great team. When they were finished, they reviewed what they had done, answered my questions, and showed me how to use the new thermostat. They made the entire process easy and interesting and even fun with their good humor. The new Lennox system is working beautifully and is making all the difference. Thank you, Tyler and Chris! You and Level 9 are the best!
