Job Checkin

I arrived for a blue member no heat call on a heat pump. I first inspected the system and found the condenser fan blade to be completely frozen over due to the snow and ice dripping onto the condenser. I made this aware to the homeowner and and explained that the defrost board dose not come with a defrost sensor and that they are two separate components. And that the system will not build up 3” of ice on top of the system when the system is running normally. The system is in the off position when the top of the system freezes over. I melted the ice off of the system with a water hose and then cycled the systems defrost mode on. The system came on on defrost and successfully melted the rest of the ice on the unit. I recommended to install a thermostat that will shut off the heatpump when the outdoor temp drops below 36-34 deg. If you decide to install this there kit please let us know and we will do our best to help you in anyway we can. Your friend at Interstate.
