Outstanding HVAC service. The tech was very competent and efficient. He explained everything he was doing and why the repairs were needed. This place has better response on a weekend than many others do on a weekday. Great communications from intake to dispatch to after-service invoices and quotes.


After dealing with almost every well known company in the IC area, I can hands down say that Schaal is THE BEST in town! We had a geothermal system that needed repair 4 times a year since we occupied the home in 2016. We’ve wanted to replace the system for a long time but the other companies who said they’d give us an estimate never followed up. Obviously they were unqualified to attempt this huge task. Schaal, on the other hand, gave us an estimate the next week. They were very conscientious about minimizing our time without AC. They left our home spotless throughout the weeklong project. They also provided a lot of knowledge and answers about our previous issues in the past. We are so happy that Schaal decided to expand their business into the Iowa City area!!! Nothing but rave reviews here! Seriously the only company you should deal with!
