Arrived to thermostat set to 69* reading 72* due to homeowner running stove to warm up downstairs. Checked temperatures upstairs and downstairs and found a 5* difference upstairs being warmer. This is normal for 2 story homes that don’t have zoning or dampers. Informed homeowner of 5* difference and the only way to make upstairs and downstairs the same is with zoning but we could use dampers to give her more comfort. Homeowner wants estimate to install dampers. Need to have the comfort advisor who quoted her new system to quote dampers if possible.
