We had such a great experience with Air Dynamics! Our AC stopped working during the summer, and everyone we dealt with was wonderful. Melissa was so friendly and helpful getting everything taken care of, and Danny and Zach did an amazing job installing our new system. They were professional, courteous, and made the whole process so much easier than I expected. They worked hard, cleaned everything up when they were finished, and took the time to make sure everything was working properly before they left. Best of all, our house feels amazing again! The new air conditioner is cooling really well and we are already noticing much better airflow upstairs. I would definitely recommend Air Dynamics Heating & Cooling to anyone in the St. Louis area who needs AC repair or a new HVAC system. Thank you Melissa, Danny, and Zach for taking such good care of our family!

Absolutely fantastic experience with Air Dynamics Heating & Cooling. Our air conditioner went out during the summer and they made what could have been a very stressful situation incredibly easy. Melissa was great to work with from the beginning and made getting everything scheduled simple. Zach came out, diagnosed the problem, explained exactly what was going on with our old AC system, and gave us our options without ever making us feel pressured. We ultimately needed a full HVAC/air conditioning system replacement, and Danny and Zach did an outstanding job with the installation. They were professional, friendly, knowledgeable, and took the time to answer every question I had. The new Carrier system is already cooling the house extremely well, and we’re actually getting noticeably better airflow to our upstairs bedrooms than we did with our old system. The entire process—from the initial service call to the new AC installation—was excellent. The price was very fair, the work looks great, and most importantly, these are people I felt completely comfortable having work in my home. If you’re looking for an honest, dependable HVAC company in the St. Louis/Fenton area for air conditioning repair, AC replacement, heating and cooling, or HVAC installation, I can’t recommend Air Dynamics enough. Thank you to Melissa, Danny, and Zach for taking such good care of us. Five stars without hesitation.

Couldn’t recommend Air Dynamics enough! We had both our AC and furnace replaced, and the entire process was so smooth from start to finish. Melissa was incredibly organized, personable, and helpful throughout. Dan and Zack did an amazing job—super professional and the quality of their work really shows. Truly would recommend them to anyone!

Heather V.
Incredibly honest and trustworthy company and amazing people. Melissa got me set up with an appointment. 10/10 customer service, she was so polite, and respectful. Dan was awesome, figured out the problem, fixed it, and showed me what happened and what to look out for. Super personable and honest guy. If you are debating on using anyone else, don't. These guys are the way to go. They will be my first and only call to get the job done. Thank you Dan and Melissa!

Alec B.
Amazing service from Dan (President) who was dispatched for my semi-annual maintenance review of my system (2nd year customer). Zach was the tech for my initial review and was great. Dan was thorough and explained everything he was doing and the measurements. He didn't rush through things. I'm a DIYer and he wasn't bothered by my constant questions about stuff (asked out for curiosity) to understand things (HVAC is outside my wheelhouse). Very happy with the level of professionalism of Air Dynamics - from the front office (Melissa) to their field experience/work. Since you found them your search for a HVAC company is over. Highly recommend without reservation if you need HVAC work.

David M.
Very professional from start to finish! We needed a system replacement and Dan and Melissa were prompt, detailed, and professional throughout. The install team of Zach and Tony were very knowledgeable, friendly, and helpful as well. Great experience from start to finish. I highly recommend them to anyone in need of HVAC services!

Matt M.
Air Dynamics is fabulous! During the cool Lest days of winter they diagnosed my furnace issues as a problem with our humidifier. Another Company said I needed to replace my furnace! Appreciate Dan’s hands on service and determination to figure out our problem!!! Jean G

Tabarak M.
After calling many places to no avail, Dan, the owner himself came out immediately at 10pm to fix our AC capacitor that went out. With a new baby, this was vital our house didn’t get too hot, we were extremely worried! He came out and had it fixed in under 30 mins. He was extremely friendly and communicated amazingly with us the whole way. Prices were beyond fair! We are happy customers! We will now be customers for the long haul and we will definitely be referring any family and friends!

Rhianna J.
Professional. Honest. Reliable. Excellent customer service. Our unit went out on a hot July 4th. Air Dynamics was on site within 24 hours and kept us cool all summer.

Chad P.
We will be customers for life! Dan was amazing to work with. Came over the day we called and had our air back on right away! Hands down one of the nicest guys, who by far went above and beyond to help our family. We have already recommended him to family and friends.

David B.
Great company with great employees! If you want an honest inspection of your home, give them a call!

Jake T.
Called them Sunday morning and they came out within a couple hours. Dan was super knowledgeable, friendly and answered all my dumb questions. Had us up and going in a half hour. Will definitely use them again. Highly recommend.

John K.
I had Air Dynamics come out and replace my leaking 18-year old R22 system recently. I chose to go with a new higher efficiency Infinity system and we are already amazed at the improved comfort and quiet operation of this new system. The workmanship is top notch and your service technicians Zack and Tony were both very professional and did a great job answering the few questions I had and cleaning up before they left. I would highly recommend your firm to anyone looking for a recommendation as well as recommending a Carrier Infinity air conditioning system.

Bob G.
A true family-owned business (unlike a lot of local companies with familiar St. Louis names but who are actually owned by out-of-town corporation$). They were very responsive. They came out the day after I called, took a thorough look, and provided a truly reasonable, transparent, no-nonsense estimate on a new air conditioning system the same day. There was no presentation or hard-sell to endure and they were able to accommodate my availability for install on short notice. They put in a high quality system and explained everything they did. They were kind to our pets. (Sidenote: I appreciate the gentleman that warned me about letting our dog eat grapes!) A truly dynamic company. I've never written a review- and probably never will again- but this business was well worth it. I would recommend them to all my family and friends. Thanks, Melissa and Dan!

steve C.
Air Dynamics provided exceptional service when I needed them most. They responded quickly, even in single-digit weather, and their pricing was fair and transparent. On top of that, their team was incredibly kind and professional. I highly recommend them to anyone in need of reliable HVAC services!

Kelly C.
We couldn’t be happier with the service provided by Dan. During a snowstorm, he came out promptly to fix our furnace, ensuring our home stayed warm and comfortable after other companies canceled on us. Dan offered a great price without compromising on the quality of his work. His professionalism, reliability, and expertise truly stood out. I highly recommend Dan to anyone in need of furnace services.

Jake W.
Dan was quick, capable and polite. He immediately solved an issue that another company couldn’t identify. Great experience.

Sarah R.
Air Dynamics, a locally owned and run business, recently replaced the HVAC system in my 100 year-old house, and I can finally breathe blessedly cool, dry air again. After the install was complete, Dan identified an attic duct issue that was dumping all the cold air into my attic, preventing the upstairs from cooling. He was committed to ensuring that everything worked properly, helped me figure out the terribly complicated thermostat, and identified/fixed a problem when I had a concern after install, and Melissa made sure it all got done! Air Dynamics also has phenomenal financing that allowed me to do this work. Two thumbs up and 5 gold stars!

C. L.
What a great company! Came out fast and not only fixed my problem on site but explained it in terms I could actually understand! Not over priced and very friendly! I will only use them in the future!

Ellen M.
Dan was so friendly and helpful!! After taking a look at the thermostat and AC unit he was able to locate the problem and explained it in a way that’s easy to understand. He shared the cost upfront and completed the repairs in a timely manner!! Definitely would recommend and will call again with any future AC/Heating needs! Thanks, Dan!!

If you are having HVAC problems you really want to call these folks. From start to finish they showed a sense of urgency, communicated well, professional, down to earth, courteous and did exactly what they said they were going to do. As we are business owners that just moved into the area we thankfully and absolutely found our go to for any of our HVAC needs.

Renee M.
Dan and his team are something special. 24 hours ago I was sitting in front of an air vent, sweating my butt off. Tonight, I’m considering throwing on a hoodie. Dan came out himself, early on a Saturday morning, and fixed the issue within minutes of arrival. Knowledgeable and friendly are just two words you use to describe the Air Dynamics team. Couldn’t be happier to have them around!

Dan B.
So happy I went with Air Dynamics. They got me a quote quickly for AC replacement and got the job done in such a timely manner. Extremely kind owner as well. I will use them for any future needs!

Kaprise S.
