Reviewed installation of ductwork in the attic space. Checked airflow setting of equipment and modified dipswitches to reduce airflow to the correct system design settings. Found 1 duct that needed to be tightened up. Measured airflows from the system and adjusted dampers to achieve the desired airflow to each supply register. Checked settings of the zoning panel to ensure the damper was set to open correctly. Airflow to the 2 bedrooms is causing slight rattling from the vents when the system is only calling for the bedroom zone to be on. There is no other balancing that can be done to improve this. The 4 registers in the bedroom zone should be replaced with new 6x12 aluminum registers to reduce noise. Reviewed trying to get a duct down to the basement area from the system in the attic. It would be best to take this off of the common plenum and include a damper; A price will be provided for this and the new registers.

* Disconnect air handler from lineset and wiring and reorient air handler to be facing parallel with attic space on front side of chimney. Reconnect all mechanicals and wiring after air handler is in place. * Run new sheet metal trunk line sized to properly handle the airflow to each space. Sheet metal will be sealed and insulated on the outside with R8 foil faced fiberglass duct wrap. * Run new branch lines using R8 insulated foil faced flex duct sized accordingly to handler the air flow required to each space in accordance with our calculations. Each branch run will have a new adhesive take off with balancing damper so the system can be properly balanced. Connect to existing supply registers. * Install new high efficiency media filter on the main return air box to improve filtration for the space and protect the equipment. * Run new 12" flex duct for return from the supply run that was removed in mud room and connect to the main return air box. * Complete all mechan

Installed 3 new mv4s in the living room, kitchen, and family room. Relocated ducts as outlined in proposal and on schematic. Modified duct work to straighten and extend certain runs to improve airflow and comfort in the living spaces. and taped off registers that are not in use anymore. Insulated hot water piping.

Luis 8-18-25 performed ac tune up on geothermal split system for second floor. (Customer has package geothermal in basement for first floor did not service this unit). Check all electrical connections and components low and high. Check airflow supply and return ok. Filter 20x20x1 ok. On attic I check the drain, coil and blower. Attic unit does not have water protection/surge protection, it also doesn't have bacteria protection. Provided information about these items. On basement (second half of the attic unit split compressor) check water pressure and temps. Compressor electric capacitor and contactor. Capacitor resurfacing below standards, rated 40 reading 30 mfd. I offered solutions and recommendations, to take care of issues. Customer sign up for service plan. We need to come back to finish up repair repairs. Replacement of capacitor and add water to geothermal loop

Reviewed ductwork again in attic space. Found sevral ducts kinked and design and install is poor. Best solution would be to replace duct syalstem and design for zoning left to right. Provided ballpark pricing of 15-20k for this. Murali just would like to clean up ducts as much as possible and relocate some ducts on main floor. Also would like to add a register in basement off if master bedroom system. Need to provide load calc on this. Also took some initial airflow neasurements.

8-8-25 Luis customer called in for oil leaks. He just got oil delivered and noticed oil filter leaking. Checked system operation found spinoff filter leaking from top. Provided estimate to replace filter. Customer approved repairs. Customer also singed up for service plan on oil boiler. After repair test operation no more oil leak. Office will contact customer sometime in fall to schedule oil boiler tune up.

Reviewed installation with Gretchen and inspected to ensure it was up to our standards. All looked good and second floor was cooling comfortably. Showed Gretchen where dampers were located. She may proceed with other duct replacement in the fall after she determines the course she will head down with the addition. Looked at returns on first floor for project she is completing in the office. She also mentioned about possibly using us for service but needs to check the warranty she has with Oliver first.
