"Our current experience started with Ryan's regular six month checkup of the system. We shared with him that we had been hearing some irregular sound during maximum heating. His evaluation led to his recommendation that we needed additional air return capability. He contacted Jeff Miller while he was here, and Jeff came out the next day to examine the situation. He agreed that additional air return capacity would be good and reviewed duct work location with us. He provided us a quote. We agreed. Today, Dave installed the ductwork and return air vent/grill. All personal interaction was professional and very pleasant. All work was done well and efficiently. In the last two years you have replaced for us our: furnace and air conditioner; sump and ejector pumps; and water heater. We have been very pleased with all work, installers, and the performance of the products. Thank you. Yes, we would and do recommend Althoff."
