TESTIMONIALS
Our Customer Stories
Jeremy is very knowledgeable and professional. Jermey explained everything the way I could understand for the every step of the diagnosing the issue and reparing the unit. I appreciate his courtesy and hard work. I am so glad that Stillwater finally has a heat and air company we can trust
I was really impressed with OnSite! My furnace went out on the coldest day, even though it was a holiday Stephanie got back to me early in the morning and Jeremy came out that afternoon to fix the problem. He explained everything to me and gave me pointers on how to improve my heating system on my own. He was kind, polite, efficient, and knowledgeable! The cost was within my budget and only exceeded my expected cost by a few dollars. I’d rate the service 5+!
Colin brings passion, integrity, and great customer service, he goes above and beyond to provide the best service needed and creates a great relationship with his customers.
