No heat
Check the thermostat and the switch that looks like a light. If the furnace is silent, call. Do not keep resetting a unit that smells wrong.
Emergency
If water is moving or the house is at 48 degrees, start here.
Sample line (920) 555-0194. This demo will not dispatch a truck.
Call the sample lineNo cooling
A frozen coil can look like a dead system. Turn it off and write. Priority members are first in the fiction.
Active leak
Shut the valve if you know which one. A photo of the meter helps the sample form. Standing water near a panel is a reason to leave the room.
What can wait
A dripping faucet until morning. A noisy pipe that has been noisy since winter. The form lets you say it is not urgent.
