Original furnace and A/C replaced after 22 years. Removal of the old equipment and installation of the new, including two new basement ducts and a cold air return took only six hours. The new system works so good we stopped using the portable A/C unit in the loft. Can't wait to test the new humidifier this winter. We are very happy with the purchase and will be recommending Thielmann/Roth to our friends and neighbors. Services: HVAC duct & vent installation, Install AC, Heating system installation
