Reviewed jobsite to look for Cooling improvements. Currently there are 2 rooftop units with ductwork from restaraunt but could not locate locate the thermostats. There is stair access through main building and walk out to roof area. Need to send technician out to aßess current units, locate the thermostats, and inspect ductwork to see if it can be reconfigured.

Reviewed system ans turned on breaker and found tripping right away. Inspected outdoor unit and checked for moisture in the disconnect. Inspected all wiring in unit. Removed compressor wires and found short of compressor winding to ground. Left disconnect off and energized breaker and breaker stays on so wiring is OK. Unit requires replacement, there is no temporary fix

Comfort issues in the home. Found home drastically imbalanced with the basement temperature at 60 degf, 1st floor set to 72 and at 72 degf, 2nd floor setpoint 72 and at 77, and loft in excess of 85 degf. Reviewed system and found zone panel calling for conditioning but 2nd floor zone damper closed. Spring open power close damper with no voltage to damper. Manually opened damper for now and checked airflow. Damper requires replacement due to spring failure. Recommend upgrading zone panel and both dampers to prevent future issues. Issue dampers is 8x18 and other dampers is 8x16. Also recommend sealing all ductwork in mechanical room as ductwork is leaking in several locations. Turned up water heater at customers request from "A" to "B". Recommend changing air filter as last filter change was March 3. Filters should be checked monthly during peak season operation. Booster fan recommendation as well to increase airflow to loft area.

Recorded photos and filter sizes for (15) Roof units where roof was accessible by my own ladder. There are (47) Rooftop units by my count (assuming there is 1 at the Citizens bank and 6 on the tallest section above where the Popeyes will be) I could not access that part of the roof so there may be 2 more. There was way too much traffic to set up ladder to get a close look at citizens bank roof. * Very important; Determine lockbock location for mounted ladder access

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.
