We were pleasantly surprised with the level of service and professionalism shown by Mike during his time at our home. We have 5 furnaces and he explained everything to us in detail, was extremely knowledgeable, courteous and willing to help. With the level of service and attention to detail that we experienced with Mike, we will definitely continue our partnership with Northwest for years to come. We recently moved from Texas to Iowa and are extremely impressed with the service we have received from Northwest. We will recommend Northwest to our friends and neighbors. Thank you for doing a great job, taking time to pay attention to the details, and giving us excellent customer service.
