Once we repair your system, we guarantee our work for 1 full year. If the repair does not solve the problem, we will refund your money for the prior repair. If you wish, we will re-diagnose the problem and repair accordingly for the cost of the new repair. Also, if at any time you are dissatisfied with our service, we will refund you the full amount of our service call and labor charges. We are truly 100% committed to providing you with the best HVAC service and want you to be excited to tell your friends about the quality of our company.
