Best Heating & Air Conditioning / HVAC In St. Charles

“Ayden Schrader was very professional, on time, and VERY knowledgeable about central air units for being a young fella. Ayden did EVERYTHING possible to fix my unit but, unfortunately, my compressor was bad.
Assured heating and cooling are looking into a possible replacement compressor or, IF I buy a new unit, I WILL definitely have Assured heating and cooling do the job. Assured heating and cooling is a MUST if you need anything done.
VERY reasonable price and a VERY professional company. If you call anyone else, you will be making a big mistake. Thank you Adyen Schrader and everyone at Assured heating and cooling. You all rock...
UPDATE--Assured came back and got my heat working that was not working. Assured is the best of the best. ALL my heating and cooling work will be done by Assured heating and cooling.“

“Our air conditioner broke down on a Sunday evening during the extreme heat! When I called I left a message figuring we’d hear back from them in the morning. Kenny called me right back and was there within 45 minutes. He diagnosed and fixed the problem within an hour! This is the second time we’ve used them and they will always be the first ones I called. Love this company!“

Very reasonable and competitive pricing; excellent customer support and the install crew was professional and a great group of guys. Aidan was our lead service specialist and he was fantastic to work with providing good advice, explanations and follow-up. Office staff was also responsive and helpful at every turn with Tracy providing timely and accurate information. Really could not have been more satisfied.“

“Called Leiber HVAC following some issues we were experiencing on our new system that was installed by another company. From the first call to the office to when the technician (Josh) arrived at our house, the communication and service were great. Josh quickly identified a couple of installation problems that were the cause of our problems. He efficiently corrected them and gave honest feedback on additional questions of ours. Our HVAC system is now comfortably heating our house! Happy to have found a new HVAC partner - thanks Leiber!“

“I have been using Pallardy (now with Arco) for over 20 years. Today, my tech was Chris W, and he was amazing! Friendly, knowledgeable and very well trained. He explained everything he was doing. He showed me all the test results, along with explaining the ranges they should fall within. This allowed me to be informed about what condition all of my components are in, as of today. I would welcome him back into my home any time. If anyone at Arco/Pallardy reads this...you have an amazing asset in this young man. Please treat him well, he is guaranteeing you return customers. I will be one of them!Services: HVAC system maintenance“
