An installer adds a UV light inside an air handler near a plastic drain pan and wiring harness. The UV kit is aftermarket but marketed for HVAC coils. What should be verified?
A new R-410A split system with a TXV has a 15 ft factory charge allowance, but the installed liquid line is 55 ft. The data plate gives an added charge per extra foot of 3/8 in. liquid line. Outdoor ambient is too low for final cooling-mode verification. How should the initial charge be established?
A hydronic coil is added in an air handler cabinet for dual-fuel heat. The installer notices the coil partially blocks blower access and has no means to purge air. What must be addressed?
At cooling start-up, measured total external static pressure is 0.92 in. w.c. on an air handler rated for 0.50 in. w.c. maximum at the selected airflow. The installer also records low airflow at the farthest bedroom. What is the best commissioning action?
A furnace is installed in a sealed mechanical closet with a louvered transfer grille to the hallway. After doors are closed, return static improves but the closet becomes strongly negative when the blower starts. What must be evaluated?
