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!

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!

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.

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!
