Recently had my furnace shut down during a cold spell. Guarenteed Mechanical arrived early the next morning and I was very happy wih the visit. The tech was very friendly and knowledgable. Excellent service.
Walker did a great job! Was able to troubleshoot the issue with the AC not cooling quickly and fixed it! Yesterday was record breaking heat index of 105-110 degrees . We were cooled off in no time. I am posting on behalf of Fischer Building and Remodeling Inc.
Chandler came out the same day our AC went out when it was in the high 80's. Tony and his crew are the best at what they do and take great care of their customers. Highly recommend!
Just had our HVAC system checked out for the first time with technician Chandler.Super impressed with his service and personality. Explained everything that he was doing and explained how everything works to my wife. She was very impressed with his personality and work ethic.Will definitely ask for Chandler again for our next service call.Great job Chandler!!!Sincerely, The Cerny’s
Guaranteed Mechanical is great! Tony answered the phone right away and was able to get his team out first thing the next morning for our office's broken A/C unit! The team was here on time, and you can tell they were very honest. As a business, we had two other companies come out and provide quotes on repair and not only was Guaranteed Mechanical accurate but they had the best, most reasonable pricing. Would recommend them to anyone.
