"They did a good job. They gave me a $40 discount since my ducts were not very dirty. My only comment is they left some particles of dry wall chips on my floor and did not vacuum them up."

"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!"

"Did excellent work and left me in a better place than I started - no more leaks! Substandard work had been done on the roof prior to buying the house, they found everything wrong and fixed it how it should have been."

"We received a great explanation about the options we have that fit our home, everything was very clear and simple we were happy with Jon proposal and we choose Service Legends to replace our HVAC system. The replacement of the old unit was done very professionally, fast and they care and respect of our property, Steven did a very great job and also take time to answer our question about our new units and the simple maintenance required. Everyone at Service legends was great and the name of the company clearly reflect the people the work for them."
