"Mack and Aaron were both EXTREMELY helpful, knowledgable, professional, polite and concerned about cleaniness (and we appreciated all those postive characteristics!). Really excellent professionals who serviced our furnance and installed a new thermostat that is really nice. We cannot recommend Schaal highly enough and Mack and Aarson were really, really good to work with. If you are seeing this and considering an HVAC company, there is no other choice than Schaal! (We have used Schaal since the early 1990s and always been totally pleased with their service, technicians and people who answer the phones!)."

"⭐⭐⭐⭐⭐ Air Free Duct Cleaning exceeded all my expectations! Their attention to detail is unmatched, and the entire process was seamless. Scheduling was a breeze, with clear communication and timely notifications about my appointment. I had a last-minute change of plans, but their flexibility allowed me to grant them access to my home while I was away, keeping my maintenance schedule on track. They did an outstanding job, even providing before-and-after photos and videos of my ductwork, which looked spotless! They may not be the cheapest, but their quality and professionalism make them the best in the business. Highly recommend!"

"Comprehensive discussion of what will be done, included pictures, good discussion of the actual mechanism that removes the radon. Once scheduled the process was completed in about 3 hours - walked me through what was done. The final product looked just liked the pictures. Discussed maintenance before leaving. All went well and was pleased. Radon's now at healthy levels."

"I could not be more pleased with this service. Not only did they get a ton of gunk out of my ducts and dryer vent, but they went above and beyond the call of duty when we discovered the previous owners of my house really didn’t have the dryer connected to the vent. They didn’t need to triage that and could have asked I get a repair person over instead. But they figured it out and were just a great team. Two thumbs up!"
