Everyone on your team is so professional, knowledgeable, polite, and friendly. It is a pleasure working with you.
Tavi and Dallas installed a new Carrier Infinity HVAC system to replace our aging system. They also installed an Aprilaire E80 dehumidifier which has in a few days changed the basement air quality. The work was completed professionally and respectively taking into consideration input from the owner. Travi and Dallas worked well together and they both took pride in their work and the results showed. Nate on the Sales Team and Paul supervising Engineer identified corrections to existing duct work which has resolved low airflow issues to the 2nd floor. We have already experienced an evenness of temperatures between the 1st and 2nd levels. Would highly recommend Team Goodco / Haller.
Water heater maintenance was superior by Johnathan. Recommended anode replacement. He added a valve on the hot water side to provide for easier isolation for maintenance.
Since anode replacement was performed during routine inspection I received a 50% discount on Anode.
