Reviewed home with John and Maryanne. They are experiencing comfort issues in the basement and are looking for a solution. Recommened rim joist sealing and adding a supply and return to basement in mechanical area. There is a fireplace in main room they use for heat. Recommend air sealing and insulating the attic space as well.

Reviewed home with James from basement to both attic spaces. There are several areas in both attics that are opportunities for making the home more comfortable and more efficient. Proposals will be emailed.

Reviewed information with Sanjay and discussed goals and expectations. The home is much larger than his previous home and only just moved there in November. He already had 2 fills on the propane totaling around $850. Electric is around $250. Walked the home and it appears pretty well sealed and insulation is acceptable but there is room for air sealing in attic and rim joists and adding some additional insulation in the attic space. There is also the potential to replace the air conditioner systems with a heat pump to lower propane usage. Follow up will be scheduled after all information is collected.

Discussed concerns with customer regarding difference in temperatures between levels of the home. Basement level was reading 60 degf and system was off, 1st and 2nd levels were reading 75 degf and setpoint was 75 degf. Bedrooms on 2nd floor were hotter than thermostat location, sun was on facing outside wall at time of assessment. Thermostat setup to automoatic for fan control. Measured airflows to registers and performed thermal imaging on areas of concern. Found barometric damper was valved off, measured basement supply registers at 25 cfm each with barometric open. Bleed through to 2 runs in basement zone. Recorded all other areas. Returns to problem bedrooms were low, supply airflow was sufficient for duct size. Recommend running system fan on thermostat in "on" position to see if it helps balancing. Also, it was indicated master bedroom feels cool, recommended closing off registers to master bedroom to move more air to other bedrooms. Room darkening blinds are recomm
